RECAP Procedure To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition feed). Proceed as follows: – Put the vehicle card in the card reader. – Press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled. – Then connect the diagnostic tool and perform the desired operations. Note: The left-hand and right-hand xenon bulb computers are powered when the dipped headlights are lit. Therefore fault finding can only be carried out on them after the ignition has been switched on in fault finding mode (forced + after ignition feed) and the dipped headlights have been switched on. To cut off + after ignition, proceed as follows: – disconnect the diagnostic tool, – Press the start button twice briefly (less than 3 seconds), – Ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the instrument panel have gone out. Faults Faults are declared as either present or stored (depending on whether they appeared in a certain context and have disappeared since, or whether they remain present but have not been diagnosed within the current context). The present or stored status of the faults must be taken into consideration when the diagnostic tool is used after the + after ignition feed has been switched on (without operation of any system components). For a present fault, apply the procedure described in the Interpretation of faults section. For a stored fault, note the faults displayed and apply the instructions in the Notes section. If the fault is confirmed when the Notes are applied, the fault is present. Deal with the fault If the fault is not confirmed, check: – the electrical lines which correspond to the fault, – the connectors on these lines (corrosion, bent pins, etc.), – the resistance of the component detected as faulty, – the condition of the wires (melted or split insulation, wear). Or use the fault finding to check the circuit of the faulty component. K9K44, 48X 84 4.0 13B-2 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - Introduction 13B Conformity check The aim of the conformity check is to check statuses and parameters that do not produce a fault display on the diagnostic tool when they are inconsistent. Therefore, this phase is used to: Run fault finding on faults that do not have a fault display, and which may correspond to a customer complaint. – Check that the system is operating correctly, and that there is no risk of a fault recurring after repair. – This section features the fault finding procedures for statuses and parameters, and the conditions for checking them. If a status is not operating normally or a parameter is outside permitted tolerance values, you should consult the corresponding fault finding page. Customer complaints - Fault finding chart If the diagnostic tool check is correct, but the customer complaint persists, it should be dealt with according to the customer complaint. A summary of the general procedure to follow is provided on the following page in the form of a flow chart.

FAULT FINDING PROCEDURE (continued) Wiring check Fault finding problems Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault. Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not present when the analysis is made (stored fault). Visual inspection Look for damage under the bonnet and in the passenger compartment. Carefully check the fuses, insulators and wiring harness routing. Look for signs of oxidation. Tactile inspection While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to present. Make sure that the connectors are properly locked. Apply light pressure to the connectors. Twist the wiring harness. If there is a change in status, try to locate the source of the fault. Inspection of each component Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on the insulating section). Make sure that the clips and tabs are properly locked in the sockets. Make sure that no clips or tabs have been dislodged during connection. Check the clip contact pressure using an appropriate model of tab. Resistance check Check the continuity of entire lines, then section by section. Look for a short circuit to earth, to + 12 V or to another wire. If a fault is detected, repair or replace the wiring harness.

NOTE Any fault on a complex system requires thorough fault finding with the appropriate tools. The FAULT FINDING LOG, which should be completed during the procedure, enables you to keep track of the procedure which is carried out. It is an essential document when consulting the manufacturer. IT IS THEREFORE COMPULSORY TO COMPLETE A FAULT FINDING LOG EVERY TIME A FAULT FINDING PROCEDURE IS PERFORMED You will always be asked for this log: – when requesting technical assistance from the Techline, – for approval requests when replacing parts for which approval is obligatory, – to be enclosed when returning monitored parts on request. The log is needed for warranty reimbursement, and enables better analysis of the parts removed. 6. SAFETY ADVICE All work on components requires that the safety rules be respected to prevent damage or injury: – Make sure that the battery is properly charged to avoid damaging the computers with a low load. – Use the appropriate tools. 7. CLEANLINESS ADVICE THAT MUST BE OBSERVED WHEN WORKING ON THE HIGH PRESSURE DIRECT INJECTION SYSTEM Risks relating to contamination: The high pressure direct injection system is highly sensitive to contamination. The risks associated with contamination are: – damage to or destruction of the high pressure injection system, – components jamming, – a component leaking. All After-Sales operations must be performed under very clean conditions. Carrying out an operation under very clean conditions means that no impurities (particles a few microns in size) should get into the system during dismantling. The cleanliness principle must be applied from the filter to the injectors. K9K44, 48X 84 4.0 13B-6 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - Introduction 13B IMPORTANT BEFORE CARRYING OUT ANY WORK ON THE INJECTION SYSTEM, CHECK WITH THE DIAGNOSTIC TOOL: – that the rail is depressurised, – that the fuel temperature is not too high. What are the causes of contamination? – metal or plastic swarf, – paint, – fibres: from cardboard boxes, from brushes, from paper, from clothing, from cloths. – foreign bodies such as hair, – ambient air, – etc. NOTE It is forbidden to clean the engine using a high pressure cleaner because of the risk of damaging connectors. In addition, moisture may collect in the connectors and create electrical connection faults. Advice to be followed before any operation Protect the accessories and timing belts, the electrical accessories (starter, alternator, electric power assisted steering pump) and the coupling face to prevent diesel fuel spilling onto the clutch assembly. Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to make them reusable). Unused plugs must be discarded. Ensure that you have hermetically resealable plastic bags for storing removed parts. There is less risk that the parts will be exposed to impurities if they are stored in this way. These are single-use bags; after use they must be discarded. Use lint free cleaning cloths (Part no. 77 11 211 707). Using normal cloth or paper is prohibited. They are not lint-free and could contaminate the fuel circuit. Each cloth should only be used once. K9K44, 48X 84 4.0 13B-7 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - Introduction 13B Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated container. For each operation, use a clean brush in good condition (the brush must not shed its bristles). Use a brush and cleaning agent to clean the unions to be opened. Blow compressed air over the cleaned parts (tools, workbench, and the parts, unions and injection system sections). Check that no bristles remain. Wash your hands before and during the operation if necessary. When wearing leather protective gloves cover them with latex gloves to prevent contamination. Instructions to be followed during the operation As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system. The plugs to be used are available from the Parts Department. They must not be reused under any circumstances. Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries impurities. All components removed from the injection system must be stored in a hermetically sealed plastic bag once they have been plugged. Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been opened. These items are likely to allow impurities to enter the system. A new component replacing an old one must not be removed from its packaging until it is to be fitted to the vehicle.

The fuel is compressed by a high pressure pump then stored in a rail that feeds the injectors. Injection occurs when a current pulse is applied to the injector holders. The injected flow is proportional to the rail pressure and to the applied pulse length, and the start of injection is phased with the start of the pulse. The circuit comprises two subsystems, which are distinguished by the fuel pressure level: – The low pressure system includes the tank, diesel fuel filter, transfer pump and injector holder return pipes. – The high pressure circuit contains the high pressure pump, the rail, the injector holders and the high pressure tubes. Finally, there are a certain number of sensors and regulating actuators for controlling and monitoring the entire system. Functions provided Function: Fuel supply management (advance, flow and pressure). Quantity of fuel injected and injection advance setting The injection checking parameters are the quantities to be injected and their respective advance. These are calculated by the computer using signals from the following sensors: Engine speed (Crankshaft + Cam lobe for synchronisation) Accelerator pedal Turbocharging pressure and air temperature (Turbocharger pressure) Coolant temperature Air temperature Air load (Flow and Pressure) Rail pressure Flowmeter Turbocharging solenoid valve The quantities to be injected and their respective advance are converted into: a reference tooth the time between this tooth and the start of the pulse the time the supply to the injector holder is active An electrical current (pulse) is sent to each injector holder according to previously calculated data. The system makes one or two injections (1 pilot injection, 1 main injection). The main principle is to calculate an overall injected flow which will then be distributed in the main injection flow, and a control injection flow to enable combustion to work properly and to reduce pollutant emissions. An accelerometer is used to monitor some of the fuel injection deviation. This has several functions: Protecting the engine by detecting injection leaks (disabled on the basic vehicle). Checking the pilot quantity by measuring deviation and dispersion. By changing both the injection duration and advance, the quantity of fuel injected and the mixture's moment of ignition can be readjusted. K9K44, 48X 84 4.0 13B-11 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B Rail pressure check The quality of combustion is influenced by the size of the atomised droplets in the cylinder. In the combustion chamber, smaller fuel droplets will have time to burn fully, and will not produce smoke or unburned particles. To meet the pollution requirements, the droplet size, and therefore the size of the injection holes must be reduced. With smaller holes, less fuel will be able to be introduced at a given pressure, which limits the power. To handle this drawback, the injected fuel flow has to be increased, which means a pressure increase (and more apertures on the injector nozzles). For the DDCR injection system, the pressure reaches 1400 bar in the rail, and must be constantly regulated. The measuring circuit comprises an active pressure sensor on the rail connected to an analogue port on the computer. The high pressure pump is supplied at low pressure (5 bar) by a built-in transfer pump. It supplies the rail, the pressure of which is controlled by the fuel flow actuator for loading, and for discharging by the injector valves. This compensates for pressure drops. The filling actuator enables the high pressure pump to supply just the exact quantity of diesel fuel required to maintain the rail pressure. This mechanism minimises the heat generated and improves engine output. In order to discharge the rail using the injector valves, the valves are actuated by short electrical pulses which are: – short enough not to open the injector (and pass through the return circuit from the injectors), – long enough to open the valves and discharge the rail. The fuel surplus is sent back to the fuel filter or the tank, according to its flow. If there is no IMV control, the rail pressure is limited by a discharge valve fitted on the pump. Idling speed regulation The computer handles the calculation of idling speed. This has to take account of the instantaneous power level to be supplied, according to the following factors: – Engine coolant temperature. – Gear ratio engaged. – Battery charge. – Electrical consumers (Heating elements, Air conditioning, Fan assembly, Heated windscreen, etc.) active or inactive, Individual injector correction (C2I) The DDCR system injectors must be calibrated with corrective values to adjust their flow precisely. Each injector is calibrated for different pressures on a test bench, and its specifications are shown on a label attached to the body of the injector holders. These individual correction values are then written to the computer EEPROM, which can then actuate the injectors by taking into account their manufacturing dispersion. K9K44, 48X 84 4.0 13B-12 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B Measuring the angular position (Cylinder reference sensor) The angular position is measured using a magneto-inductive sensor activated by machined teeth on the crankshaft flywheel. This flywheel has 60 teeth separated by six degrees minus 2 missing teeth, that form a notch. A second sensor (Hall effect) activated by a machined tooth on the high pressure pump drive pulley (synchronised with the camshaft) and which rotates at half the engine speed, supplies an injection cycle running signal. By comparing the signals from these two sensors, the computer's APS module (Angular Position Subsystem) can supply the entire system with the synchronisation factors, which are: the angular position of the flywheel, the engine speed, the number of the active injector and the injection cycle advance. This module also supplies the system with the engine speed signal. Flow capacity function (VLC) Because of the combination of several parameters such as the diesel fuel temperature, part wear, clogging of the diesel filter etc., the system limit may be reached during its service life. If this happens, the rail pressure cannot be maintained because the pump lacks the necessary capacity. If the pump lacks the necessary capacity, this programming will therefore reduce the requested flow to a value that will enable the pressure monitoring system to control the pressure again. The customer may have noticed a loss of vehicle performance when this program is activated (confirmed by ET563 Flow capacity function). This is part of normal operation. Function: Air flow management. EGR valve control The EGR system (Exhaust gas recirculation) comprises a proportional EGR valve, with a built-in valve position feedback potentiometer. The EGR valve position is controlled by the potentiometer in a closed loop and/or by changes in the estimated air flow. Calculating the air flow WITHOUT FLOWMETER (K9K 722) Certain models are not fitted with air flowmeters. In this case the amount of fresh inlet air must be evaluated, based on the values supplied by the surrounding systems. The (theoretical) air volume is calculated using a model with various calculation parameters, which are: – the inlet air temperature measured by a sensor located after the turbocharger and/or after the exchanger (if fitted), – the turbocharging pressure, – the atmospheric pressure (external air), – the EGR valve position, – the fuel flow, – the engine speed. The atmospheric pressure sensor is optional. If fitted, it sends back an atmospheric pressure signal to an analogue port on the micro-controller. If not, atmospheric pressure is found from the turbocharger pressure and the engine field. K9K44, 48X 84 4.0 13B-13 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B WITH FLOWMETER (K9K 728) The flow of fresh air entering the engine is given by a hot wire ratiometric sensor. This flowmeter is used to manage the amount of exhaust gas to be recirculated to ensure optimum recirculation rates. A fresh air temperature sensor is built into the flowmeter. Air flow measurement allows closed-loop control via the EGR valve. Besides electrical faults with the sensor, there is a consistency test between the measured air flow and an estimated air flow without EGR. This flow evaluates the amount of fresh inlet air, based on the values supplied by the surrounding systems, which are: – the inlet air temperature measured by a sensor located after the turbocharger and/or after the exchanger (if fitted), – the turbocharging pressure, – the engine speed. Pre-postheating actuation Pre-postheating actuation consists of controlling the heater plugs and preheating warning light on the instrument panel. The heater plugs are activated by relays, and the power is supplied from the battery. After the ignition is switched on. Preheating is activated for a period of time. The warning light is lit for the activation period which is dependent on the battery voltage, atmospheric pressure and coolant temperature. If the temperature is below a certain threshold, a postheating function can be used to improve the combustion stability, and consequently engine operation (reducing unburnt particles and pollutant emissions). Turbocharger control solenoid valve actuation The turbocharger system comprises a solenoid valve that is used to actuate the vanes (or wastegate) to create an overpressure or an underpressure in the inlet circuit. Functions included Air conditioning management assistance For vehicles with air conditioning, the DDCR system can switch off the air conditioning in certain engine operating conditions: – when requested by the driver, – when starting the engine, – if the engine overheats (in order to reduce the power the engine has to supply), – when the engine speed is kept at a very high level (to protect the compressor), – during transition phases (e.g. high acceleration demand for overtaking, anti-stalling and pulling away). These conditions are only taken into account if they do not occur repeatedly, so as to prevent system instabilities (erratic deactivation), – when certain faults appear. K9K44, 48X 84 4.0 13B-14 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B Cold loop air conditioning management The air conditioning is cold loop managed, shared between several computers. The injection computer is responsible for: – managing demand for cold air according to the passenger compartment commands and the pressure value, – determining the power absorbed by the compressor from the pressure, – determining the fan assembly commands according to vehicle speed and pressure. The driver requests the air conditioning to be switched on by means of the ventilation selector coupled to a switch. The cold air request is authorised or denied depending on the pressure measured. If this pressure is outside the operating limits, the cold loop program is not activated. Note: Requests to operate the fan assembly can be made by the injection computer but these are sent on the CAN. These requests depend on the air conditioning but also on the coolant temperature and vehicle speed. Thermal regulation of the passenger compartment heating circuit In a direct injection engine, fuel is injected directly into the combustion chamber. This leads to heat being lost through the upper part of the engine and consequently, the cylinder head cooling circuit is smaller in size. The effect of this is that the temperature of the coolant which flows through this circuit rises more slowly. This coolant is also used by the passenger compartment heating system. In very cold conditions, it is therefore difficult to achieve a comfortable passenger compartment temperature quickly. To limit the heating time, air heating resistors, called RCH (passenger compartment heating resistors), are fitted into the passenger compartment heating circuit. The UCH decides whether or not the passenger compartment heating resistors are required; the Protection and Switching Unit physically controls the passenger compartment heating resistors; and the injection computer determines whether to limit the power supplied to the passenger compartment heating resistors depending on alternator load and also whether to prohibit the operation of the passenger compartment heating resistors according to engine speed, load and vehicle speed. K9K44, 48X 84 4.0 13B-15 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B Cruise control/speed limiter management: When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the driving conditions encountered. Using the control buttons, the driver can increase or reduce the speed of the vehicle. The cruise control function can be deactivated either by using the control buttons, or by switching off the cruise control function selection switch or when system events are detected such as depression of the brake or clutch pedals, or when system errors are detected such as an incorrect vehicle speed or a deceleration level which is too great. The cruise control function can also be temporarily suspended when the driver wants to resume control of the vehicle and exceed the selected cruising speed by depressing the accelerator pedal which then exceeds the selected fuel flow. The cruising speed is resumed when the driver releases the accelerator pedal. The cruise control function can be reactivated and the last cruising speed can be reselected after deactivating the function for whatever reason until the ignition is switched off (i.e. for as long as computer supply voltage is not switched off). The vehicle will then attempt to return to the cruising speed using a controlled vehicle acceleration rate. When switched on using the selection switch, the vehicle speed limiter function limits the vehicle speed to a preset value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached. If an attempt is made to exceed this speed, the system will ignore the pedal demand and will control the vehicle speed as it does with the cruise control function, provided that the driver continues to press the accelerator pedal. Like for the cruise control function, the cruising speed can be altered using the control buttons by means of a quick or a sustained press. For safety reasons, the cruising speed can be exceeded by depressing the accelerator pedal beyond the pedal position limit value; the accelerator pedal regains full control until the vehicle speed falls back below the cruising speed, when the limiter function is reactivated. The driver has the following controls for the cruise control/speed limiter function: – accelerator pedal, – brake pedal, – clutch pedal, – function selection switch, used to select cruise control or speed limiter operating mode. K9K44, 48X 84 4.0 13B-16 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - System operation 13B Instrument panel display The computer manages the data display on the instrument panel relating to engine operation. This concerns five functions: The MIL (Malfunction Indicator Lamp) for the EOBD (European On Board Diagnostic), pre-postheating, coolant temperature and engine faults: Level 1 (non-critical fault) and Level 2 (emergency stop). These five functions are represented by 3 warning lights or messages displayed by the trip computer. Pre-postheating warning light This warning light is used both as an in operation indicator light and as a system fault indicator: – permanently lit during + after ignition feed: indicates preheating of the heater plugs. After preheating and an automatic timed 3 second off period, the warning light will come on if a Level 1 fault occurs (leading to reduced operation and reduced safety levels. The user must carry out repairs as soon as possible). Temperature/emergency stop warning light This warning light is used both as an in-operation indicator light and as a system fault indicator. It comes on for 3 seconds when switched on (automatic test procedure managed by instrument panel). Permanently on: this indicates engine overheating or a level 2 fault. – if the fault reaches a critical level, the injection cuts off automatically after a few seconds. – in the event of overheating, it is up to the driver whether to stop the vehicle or continue driving. WARNING LIGHT ACTIVATION PROGRAMMING ON THE INSTRUMENT PANEL Orange SERVICE warning light (level 1) This warning light comes on, accompanied by message Injection Faulty. The driver should carry out repairs as soon as possible. Red STOP warning light (level 2) This warning light comes on, accompanied by message Injection Faulty. The driver should carry out repairs as soon as possible. Excess pollution OBD ORANGE warning light: This warning light is used to alert the driver of any injection faults causing excessive pollution, or if the EOBD system has been deactivated. The injection computer requests activation of the OBD warning light for a present fault only after three successive driving cycles. The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the instrument panel) is carried out by the injection computer.

The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic tool (Consult Technical Note 3585A and follow the instructions provided by the diagnostic tool). NOTE – Switch on the diagnostic tool (mains or cigarette lighter supply). – Connect a battery charger. – Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.). – Wait for the engine to cool (engine coolant temperature below 60 °C and air temperature below 50 °C). Every time the computer has been reprogrammed or replaced – Switch the ignition off and then on again. – Use the diagnostic tool command SC001 Enter saved data to restore C2 and the engine adaptives. – Use command AC212 New pump chamber filling. – Press the Start button (repriming time until the engine starts may take 20 seconds). – After the engine has started, refer to ET637 New pump chamber filling and check that it is Done. If not, repeat the starting procedure. – Stop the engine, switch off the ignition (to initialise the computer) and wait 30 seconds. – Switch on the ignition again and use the diagnostic tool to carry out the following steps: – Use command VP010 Write VIN. – After injection system (re)programming, stored faults may appear in other computers. Clear the memories of these computers. – Carry out a road test followed by another check with the diagnostic tool. Note: If commands SC001 and SC003 are ignored or do not work, after replacing or (re)programming the computer write the C2I codes for each injector manually by reading the C2I code on each injector (see replacing injectors). – Use command AC028 Static test to autoconfigure the computer (fan assembly, etc.). NOTE It is not possible to try an injection computer from the Parts Department because it will no longer be possible to fit it on another vehicle. K9K44, 48X 84 4.0 13B-22 Edition 2 DDCR INJECTION Vdiag N°°: 44, 48 DIESEL INJECTION Fault finding - Replacement of components 13B REPLACING THE INJECTORS Note: The C2I (individual injector correction) is a factory calibration applied to each injector, to adjust the flow of each of them precisely. The correction values are written on a label affixed to each injector, then entered in the computer which can then actuate each injector by taking account of their manufacturing variation. The system can be set up using the diagnostic socket with the RENAULT CLIP diagnostic tool. The C2 parameters must be replaced after replacing an injector/injectors. To do this, reprogram the C2I into the computer using the following commands: – injector cylinder 1: command VP001 (flywheel end cylinder), – injector cylinder 2: command VP002, – injector cylinder 3: command VP003, – injector cylinder 5: command VP004. It is also possible to enter the four C2I codes using command SC002 ENTER INJECTOR CODES. The technician will use the appropriate command to enter the new C2I for the replaced injector and erase the old C2I. – Only after having simultaneously replaced of at least 3 injectors should you reset the injector adaptives using the command RZ004 Pressure regulation for adaptives. HIGH PRESSURE PUMP REPLACEMENT When replacing a high pressure pump on a vehicle fitted with a computer with Vdiag 48, apply the following procedure before starting the engine. When replacing a high pressure pump on a vehicle fitted with a computer with a Vdiag 44, it is essential to reprogram the injection computer (see Replacement of components). This reprogramming will install new functions in the computer to enable the injection pump to be reprimed with diesel without damaging it. After reprogamming, Vdiag 44 is replaced by Vdiag 48. PROCEDURE – Switch on the ignition and establish dialogue with the injection computer. – Use command AC212 New pump chamber filling. – Press the START button (repriming time until the engine starts may take 20 seconds). – After the engine has started, refer to ET637 New pump chamber filling and check that it is Done. If not, repeat the starting procedure. REPLACING THE EGR VALVE When replacing an EGR valve, it is essential to clear the EGR adaptives using command RZ002 EGR adaptatives.

A second sensor (Hall-effect sensor). the number of the injector that's active and the progress of the injection cycle. the camshaft sensor enables a distinction to be made between these two states. the computer is able to provide all its systems with synchronisation parameters.: B1 DIESEL INJECTION Fault finding . The injector voltage is very high (much higher than that of conventional injectors) This voltage can be as much as 150 V. namely: the angular position of the flywheel.: 44 Program No. this is known as the crankshaft or TDC sensor. provides a signal relating to the progress of the injection cycle. 2 of these teeth are missing to form a notch. at the correct time. which turns at half the engine speed. The angular position is measured by means of a magneto-inductive sensor which is excited by the teeth machined onto the flywheel. this will not affect the operation of the engine. IMPORTANT! Engine synchronisation One of the determining factors for fuel injection control is knowing the position of each of the pistons in their respective cylinders at all times. Up to a certain rate. – Fuel temperature.System operation 13B Quantity of fuel injected and control of start of injection The parameters for controlling injection are. – Coolant temperature. – Accelerator pedal position. – Air flow – Pressure of fuel in the rail. Air valve control By default the valve is open when in the rest position and is actuated only when the engine is switched off. the quantity to be injected and the start of injection. the coefficients are initialised to 1. compression rate. The regulation process is only active at idle speed. An air temperature sensor is integrated into the flow sensor. Turbocharger control The turbocharger system consists of a solenoid valve connected to the vacuum pump circuit.: 44 Program No. EGR valve control The EGR (exhaust gas recirculation) system consists of a direct current EGR valve fitted with a valve position sensor. thus ensuring the best possible recirculation rates. etc.) which affect the torque generated by each cylinder during combustion. this is "learning" all the time the regulation process is active and remains fixed at the last value that was learned when the regulation is inactive. At each new cycle. – Turbocharging air pressure. An injection timing correction coefficient is assigned to each cylinder. this has a damping effect and helps to stop the engine. Station to station flow regulation The aim of this regulation process is to facilitate smooth engine operation by compensating for the system variations (injectors. The EGR valve is controlled in a closed-loop via the position sensor. These are calculated by the injection computer from the following information: – Engine speed.: B1 DIESEL INJECTION Fault finding . exhaust gas recirculation enables nitrogen oxide (NOx) emissions to be reduced significantly. The flow sensor facilitates control of the quantity of exhaust gas sent for recirculation. – Air temperature.Siemens SID301 injection system Vdiag No. this enables the vanes to be controlled by means of a diaphragm so as to create either an overpressure or a vacuum in the fresh air inlet circuit. with a warm engine and on condition that the engine speed is sufficiently stable. Air flow measurement allows closed-loop control via the EGR valve. Siemens SID301 Injection 13B-12 Edition 3 . AIR SUPPLY Measurement of the fresh air flow The flow of fresh air entering the engine is calculated by a flow sensor (ratiometric hot-wire sensor). for each cylinder. The injection computer requests the UPC to activate them via the multiplex network. Siemens SID301 Injection 13B-13 Edition 3 . MANAGEMENT OF ENGINE COOLANT TEMPERATURE Engine cooling is guaranteed by a 2-speed fan unit (GMV) (slow: GMV1 and fast: GMV2). Preheating is activated for a period of time. GMV2 is activated when the coolant temperature exceeds 104°°C and is deactivated when it drops below 102°°C.System operation 13B IDLE SPEED MANAGEMENT The injection computer is responsible for regulating the idle speed as a function of the idle speed setpoint which it calculates. The computer arbitrates between the inter-system torque requests and the driver's request (comprised of the accelerator pedal or the cruise control/speed limiter function). To provide cooling: – Engine running GMV1 is activated when the coolant temperature exceeds 96°°C and is deactivated when it drops below 94°°C. – the gear engaged. Each inter-system (ESP. atmospheric pressure and coolant temperature. automatic gearbox. a postheating function enables combustion stability. the computer determines the quantity of fuel to be injected (injection duration and number of injection processes) and the amount of air required (turbocharging pressure and EGR rate) so that the engine is able to provide the torque required in the best possible conditions (in terms of smooth running performance. The result of the arbitration gives the torque setpoint.). etc. ENGINE TORQUE MANAGEMENT The torque structure is the system which translates the driver's request into a torque supplied by the engine.: 44 Program No. – air conditioning requirements. The heater plugs are activated by a relay box and the power is provided by the battery. It is required for certain functions such as the electronic stability program (ESP). After the ignition is switched on. sequential gearbox) sends the injection computer a torque request via the multiplex network. When the coolant temperature is below a certain threshold. MANAGEMENT OF PRE/POSTHEATING Pre-postheating management involves controlling the heater plugs and the heater plugs indicator light in the instrument panel (via the multiplex network). pollutant emissions.: B1 DIESEL INJECTION Fault finding . The indicator light comes on for the activation period which is dependent on the battery voltage. The idle speed setpoint is dependent on: – the coolant temperature.Siemens SID301 injection system Vdiag No. and thereby engine operation. the automatic gearbox or the sequential gearbox if fitted). – the emission control programs. – battery voltage. From this torque setpoint. – the electrical consumers. to be improved (reduction in unburnt fuel and pollutant emissions). the injection computer requests the UPC computer. heated rear screen. performance. etc. – Airbags. OTHER HOSTED FUNCTIONS The other functions hosted by the computer are: – CAN.) for engine operation purposes such as: start-up.. These requests pass via the multiplex network to the Protection and Switching Unit where they are converted before being sent to the alternator. the injection computer requests the instrument panel computer. to switch on the coolant temperature warning light. – Engine immobiliser. INTER-SYSTEM EXCHANGES The inter-system connections concerning the particular requirements of engine management are as follows: – Request for instrument panel computer to illuminate the OBD warning light to warn of an OBD-related pollution fault. – Request to shut down the air conditioning compressor for engine programming requirements such as start-up. overspeed. – Engine stop management. If the engine coolant temperature exceeds the threshold of 115°°C. the injection computer requests that the coolant temperature warning light is lit and that GMV2 is activated. – Cruise control/speed limiter. This enables engine smooth-running performance to be improved in the critical operating phases. – Request to light the Level 1 warning light to warn of an operational safety fault with the engine management system which may restrict performance. The cut-off request is cancelled if the coolant temperature drops below 110°°C. – Formulation of requests to engage electrical consumers and limit power based on rail conditions. anti-stalling. – Trip Computer. – Starter management.System operation 13B If the engine coolant temperature exceeds the warning threshold of 120°°C. anti-stalling. via the multiplex network.Siemens SID301 injection system Vdiag No. Siemens SID301 Injection 13B-14 Edition 3 . – Request to start the Fan units for engine cooling and also for air conditioning purposes. If a fault in the coolant temperature sensor circuit is detected.: 44 Program No. etc. etc.: B1 DIESEL INJECTION Fault finding . The warning stops if the coolant temperature drops below 117°°C. In addition to engine management. – Request to light the Engine overheating warning light to warn of an engine overheating fault or a fault in the coolant temperature sensor. to switch off the air conditioning compressor so as to reduce the load on the engine and attempt to limit the rise in temperature. performance. overspeed. This last function is made possible with the introduction of alternator control. – Panic hardware. via the multiplex network. – Heating and ventilation. – Request to light the Level 2 warning light to warn of an operational safety fault with the engine management system which may result in the engine stopping. mainly at idle speed and when starting up. the injection computer centralises the cooling requirements for the climate control and automatic transmission/sequential gearbox functions (where fitted). – Request to switch off electrical consumers (passenger compartment heating resistor (RCH).

Finally. The amount injected is proportional to the rail pressure and the applied pulse length. diesel fuel filter. the quantity of fuel injected and the mixture's moment of ignition can be adjusted. An electrical current ("pulse") is sent to each injector holder according to previously calculated data. These are calculated by the computer using signals from the following sensors: – engine speed (crankshaft + cam lobe for synchronisation). Functions performed: Function: Fuel supply management (timing. DCM1.2 injection system used on the K9 engine is an electronically-managed high-pressure injection system. An accelerometer checks some of the fuel injection deviation.: 48 DIESEL INJECTION Fault finding . and the start of injection is synchronised with the start of the pulse. The general principle is to calculate the total injection flow which is then divided between the injection stages to promote correct combustion and reduce pollutant emissions. The fuel is compressed by a high pressure pump then stored in a rail that feeds the injectors.DCM 1.

The system includes two subsystems. – air temperature (flow sensor). – the time between this tooth and the start of the electrical impulse. Injection takes place when a current pulse is applied to the injector holders. which have different fuel pressure levels: – the low pressure system includes the tank. – accelerator pedal. – turbocharging pressure sensor.0 Injection 13B-11 . one post-injection). – air load (calculated flow rate). The quantities to be injected and their respective timing are converted into: – a reference tooth. one pre-injection. The system carries out one to four injections (one pilot injection.: 4D Vdiag No. This has several functions: – Protecting the engine by detecting injection leaks (disabled on the basic version). there are a certain number of sensors and regulating actuators for controlling and monitoring the entire system. – the time the injector holder is supplied. System operation 13B Rail pressure check The quality of combustion is influenced by the size of the spray droplets in the cylinder.

Each injector is calibrated for different pressures on a test bench. less fuel will be able to be introduced at a given pressure. – gear ratio engaged.2 X84 V1. Idling speed regulation The computer handles the calculation of idling speed. This has to take account of the instantaneous power level to be supplied. This compensates for pressure drops. and its specifications are shown on a label attached to the body of the injector holders. The filling actuator enables the high pressure pump to supply the exact quantity of diesel fuel required to maintain the rail pressure. The rail filling pressure is controlled by the filling valve (IMV) and the discharge pressure is controlled by the injector valves. taking their manufacturing variations into account. which can control the injectors.: 48 DIESEL INJECTION Fault finding . heated windscreen.) active or inactive. the pressure in the rail can reach 1600 bar and must be constantly controlled. The fuel surplus is sent back to the fuel filter or the tank. which means increased pressure (and more holes in the injector nozzles). In the Delphi Common Rail injection system. – long enough to open the valves and discharge the rail.: 4D Vdiag No. This pump supplies the rail. the rail pressure is limited by a discharge valve fitted on the pump. smaller fuel droplets will have time to burn fully.

The High Pressure pump is supplied at low pressure (5 bar) by a built-in transfer pump. etc. the droplet size must be reduced and therefore the injection holes must be smaller. – electrical consumers (Additional heater. In order to discharge the rail using the injector valves. To offset this disadvantage. To meet emission control requirements. the valves are actuated by short electrical pulses which are: – short enough not to open the injector (fuel passes through the return circuit from the injectors).DCM 1. – system faults detected. according to the condition of the following factors: – engine coolant temperature. These individual correction values are then entered into the computer memory. the quantity of fuel injected must be increased. if the key is released before the end of this "first starting" phase there is no need for a power latch phase before a fresh attempt to start the vehicle. which is the time required for filling the pump and starting. DCM1. the number of the active injector and the injection cycle timing. The lubrication goes through a procedure called new pump chamber filling. This procedure runs after the first start in the factory. this programming will therefore reduce the required flow to a value that will enable the pressure monitoring system to control the pressure again. which prevents starting for approximately 10 s.System operation 13B Angular position measurement Engine speed sensor: The angular position is measured using a magneto-inductive sensor triggered by machined teeth on the shaft flywheel. This flywheel has sixty teeth. Variable Low Capacity (VLC) output function Because of the combination of several parameters such as the diesel fuel temperature.0 Injection 13B-13 . Cylinder reference sensor: A second sensor (Hall effect) triggered by a machined tooth on the high-pressure pump drive pulley (synchronised with the camshaft). supplies information about the progress of the injection cycle. which are: the angular position of the flywheel.

You must respect the cleanliness guidelines and safety advice specified in this document when completing any work on the high-pressure injection system. As a result: – the activation of the fault warning lights on the instrument panel is performed by the multiplex network. – the vehicle speed sensor on the gearbox is no longer required. The driver requests the air conditioning to be switched on by means of the ventilation selector coupled to a switch. from the UPC. – during the engine starting phases.

If this pressure is outside the operating limits. the damper valve closes by a few % in order to create a Venturi effect in the EGR valve flow section. the EDC16 system has the option of deactivating the climate control through the UCH. high acceleration demand for overtaking. Management of the damper valve: The damper valve now carries out two functions: – Damping: when the engine is switched off. EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - System operation 13B Passenger Compartment Heating Resistor Management: In order to reduce the time required to heat up the passenger compartment, the vehicle is fitted with Passenger Compartment Heating Resistors (RCH). These resistors are managed by the UCH. The injection computer gives authorisation to the resistors according to the operational phases and the engine output. Cruise control/speed limiter management: The vehicle cruise control function, when activated, allows you to keep the vehicle speed at a selected value regardless of the driving conditions encountered. Using the control buttons, the driver can increase or reduce the speed of the vehicle. If the driver wishes to exceed the limit speed, he/she may: – depress the accelerator pedal and exceed the cruising speed (the vehicle will return to the original cruising speed once the driver takes his/her foot off the pedal), – press the system control buttons. The cruise control function can be deselected either by: – the system control buttons, – switching off the cruise control switch, – when system events are detected, such as the brake or clutch pedal being depressed, – when system errors are detected such as an erratic vehicle speed. The cruise function can also be temporarily inhibited when the driver wants to increase speed by depressing the accelerator pedal. The cruising speed is resumed when the driver releases the accelerator pedal. The vehicle will then attempt to reach the cruising speed at a controlled acceleration rate. It is possible to reactivate cruise control and resume the last cruising speed after deactivation (computer supply not switched off). When activated (using the selection switch) the vehicle speed limiter function limits the vehicle speed to a preselected value. The driver controls the vehicle in the normal way using the accelerator pedal until the setpoint speed is reached. If an attempt is made to exceed this speed, the system ignores the pedal request and controls the vehicle speed in the same way as the cruise control function, provided that the driver keeps the accelerator pedal sufficiently depressed. As with the cruise control function, the setpoint speed can be modified by pressing or pressing and holding the control buttons. For safety reasons, the setpoint speed can be exceeded by depressing the accelerator pedal so as to exceed a pedal position limit value. The vehicle speed is then totally controlled as a function of pedal position until the speed falls back below the setpoint speed when the speed limiter function will once again be reactivated. If the driver wishes to exceed the limit speed, he/she may: – exceed the accelerator pedal's kickdown point, – increase the limit speed by the pressing or pressing and holding the limit speed switch. The speed limiter function can be deselected either by: – the system control buttons, – turning off the speed limiter switch, – when system events are detected, such as the brake or clutch pedal being depressed, – when system errors are detected such as an erratic vehicle speed. 13B-14 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - System operation 13B Exhaust gas recirculation management The exhaust gas recirculation system comprises a direct current EGR valve controlled by an H bridge in the computer. This system has a built-in valve position feedback potentiometer. The EGR valve is controlled in a closed loop on the change in the air flow measured by the flow sensor. The potentiometer is used in the fault finding procedure for the EGR valve position. Catalysed particle filter management The particle filter eliminates the emission of carbonated particles emitted by the engine that have not yet been removed from the exhaust fumes. The particle filter has a microporous structure containing channels in order to force filter the exhaust fumes. The exhaust system consists of several components: – an oxidation catalytic converter located after the turbocharger. This catalytic converter allows the HC/CO levels to be attained in line with current standards and to generate an exotherm (rise in exhaust temperature by means of catalysis) required for particle filter regeneration, – a catalysed particle filter located under the bodywork, – a pressure differential sensor to inform the computer of the pressures upstream and downstream of the particle filter particle filter upstream and downstream temperature sensor, – a temperature sensor upstream of the turbine (TAVT). When driving, the particle filter is loaded with particles (soot). Using a given weight of soot determined via computer mapping, regeneration mode can be triggered when the maximum weight of soot in the particle filter is reached and the engine operating conditions are met (coolant T°, etc.) Particle filter regeneration consists of burning the particles of soot accumulated in the filter. The pressure differential sensor measures the particle filter input/output pressure differential. This measurement is used to estimate the weight of soot present in the particle filter via the mappings in the computer: (soot weight = pressure differential in accordance with exhaust volume flow rate). If all the criteria are met, the computer enters regeneration mode. The injection programming is then adjusted in order to raise the target exhaust gas temperature between 550 and 650°°. This temperature allows the particles accumulated in the filter to be partially or completely burnt (regenerated). The efficiency of regeneration depends on the particle filter inlet temperature and the time spent in regeneration mode. Regeneration may be automatic when driving if the soot weight is under 45 g. If the soot content is above 45 g or it has not been possible to perform regeneration when driving, the user will have to request an After-Sales regeneration. This regeneration is carried out in the workshop. It is imperative that the instructions described in the Interpretation of commands for this Note are followed, to safely carry out the regeneration. NOTE The particle filter should be replaced after a period of time which is largely dependent on the quality of the engine oil used - this information is found in the Driver's handbook. It is essential, after replacing the filter, to reconfigure certain parameters in the computer. 13B-15 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - System operation 13B Warning light management: Instrument panel display The computer manages the data display on the instrument panel relating to engine operation. This concerns five functions: – the pre/post heating operating light, – the coolant temperature warning light, – the fault level 1 warning light (non-critical fault), – the fault level 2 warning light (emergency stop), – EOBD (European On Board Diagnostic) OBD warning light. These five functions are represented by 3 or 4 warning lights and/or messages transmitted by the trip computer. Orange pre/post heating/non-critical fault "SERVICE" warning light (level 1) This warning light is used both as an in operation indicator light and as a system fault indicator: – Continuously lit with + after ignition feed: Indicates plug preheating. – Continuously lit with the "CHECK INJECTION" message: Indicates a level 1 fault (implies operation in injection system defect mode). The driver should carry out repairs as soon as possible. Temperature/red emergency "STOP" (level 2) warning light This in operation indicator light is used both as an in operation indicator light and as a system fault indicator light. Lights up for 3 seconds when the ignition is switched on (automatic test procedure managed by the instrument panel): – Continuously lit: Indicates engine overheating (the driver is free choose whether or not to stop the vehicle). – Continuously lit with the "FAULTY INJECTION" message: Indicates a level 2 fault (In this case, the injection is automatically cut after a few seconds). The driver should carry out repairs as soon as possible. "ORANGE" "OBD" excess pollution warning light Symbolised by an engine, it lights up for approximately 3 seconds when the engine is switched on. This warning light lights up if the system has one or more OBD faults. This warning light is used to alert the driver of any injection faults causing excessive pollution, or if the EOBD system has been deactivated. The injection computer requests activation of the OBD warning light for a present fault only after three successive driving cycles. The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the instrument panel) is carried out by the injection computer. 13B-16 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - System operation 13B Management of the EOBD: The OBD (On Board Diagnostic) system enables any faults relating to the vehicle emission control system (OBD EURO IV emission control standards being exceeded) to be detected. This system should be active for the entire life of the vehicle. 1. Conditions causing an OBD fault An OBD fault will be detected after 3 driving cycles and the following parameters will be registered in the computer: – engine load, – vehicle speed, – air temperature, – coolant temperature, – turbocharging pressure, – rail pressure, – air flow, – distance travelled in miles by the vehicle since activation of the "OBD" warning light. It allows the driver to know whether his vehicle has a fault directly linked to the emission control system. 2. System faults indicated by the OBD Only a few faults are indicated by the OBD system: – DF012 "Sensor supply voltage no. 2". – DF038 "Computer" in 6.DEF "EEPROM fault". – DF040 "Cylinder 1 injector circuit" in CO "Open circuit". – DF041 "Cylinder 2 injector circuit" in CO "Open circuit". – DF042 "Cylinder 3 injector circuit" in CO "Open circuit". – DF043 "Cylinder 4 injector circuit" in CO "Open circuit". – DF054 "Turbocharging solenoid valve control circuit" in CC.0 "Short circuit to earth". – DF209 "EGR valve position sensor circuit". – DF621 "EGR valve jammed open". Some repair operations require programming to ensure that certain engine components function correctly. Follow the programming procedures (see "Replacing components"), if replacing the exhaust gas recirculation valve or an injector. 3. Conditions for clearing an OBD fault An OBD fault is cleared in several steps. The fault present in the diagnostic tool is not stored (following repair) until the vehicle is driven 3 times. The OBD warning light will only light up after these 3 driving cycles. The warning light coming on does not always mean that there is a fault on the system. In order that the OBD fault and the display parameters are cleared from the computer, the system needs to go through 40 engine heating cycles. An engine heating cycle is a driving cycle during which: – the engine coolant temperature reaches at least 71.1 °C, – the engine coolant temperature varies by 22.2 °C in relation to the engine starting temperature. If one of these conditions is not fulfilled, the OBD fault will still be present or stored in the injection computer. 13B-17 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Allocation of computer tracks 1 - 32-track black connector A 13B 2 - 48-track brown connector B Track Description Track Description A1 A2 A3 Not used Cruise control on/off control Passenger compartment CAN L1 network signal Passenger compartment CAN H1 network signal Air conditioning inhibition control Engine speed signal Not used K line diagnostic socket output Not used Not used Speed limiter on/off control Clutch supply signal output UPC feed (+ after ignition) Cruise control programming control Cruise control programming feedback signal Fuel flow signal Not used Air conditioning cycle control Heated windscreen activation signal Brake switch supply signal output Not used Accelerator potentiometer load 2 supply Accelerator potentiometer load 2 signal Accelerator potentiometer load 2 earth UPC feed (+ BAT 1 after relay) Accelerator potentiometer load 1 supply Not used Battery earth Battery earth Accelerator potentiometer load 1 signal Accelerator potentiometer load 1 earth Battery earth A1 Camshaft sensor earth (cylinder 1 reference) and particle filter upstream temperature sensor Additional heating fault finding signal Not used Fuel rail pressure sensor supply TDC sensor supply signal (engine speed) Damper valve fault finding Not used Air flow sensor supply TDC sensor earth signal (engine speed) EGR valve engine supply signal Engine CAN H2 network signal (automatic gearbox) Fuel rail pressure sensor earth Camshaft sensor signal (cylinder reference 1) EGR valve engine earth signal Engine CAN L2 network signal (automatic gearbox) Turbocharger pressure sensor earth Main power supply relay control Air temperature and air flowmeter earth signal Not used Not used Refrigerant pressure sensor signal Coolant temperature sensor supply signal Refrigerant pressure sensor supply EGR valve position potentiometer feed Air flowmeter supply signal Air temperature signal Fuel rail pressure sensor signal Turbocharging pressure sensor and particle filter pressure differential sensor supply Coolant temperature sensor earth Not used Particle filter upstream temperature sensor signal Electric coolant pump relay control A4 B1 B2 B3 B4 C1 C2 C3 C4 D1 D2 D3 D4 E1 E2 E3 E4 F1 F2 F3 F4 G1 G2 G3 G4 H1 H2 H3 H4 A2 A3 A4 B1 B2 B3 B4 C1 C2 C3 C4 D1 D2 D3 D4 E1 E2 E3 E4 F1 F2 F3 F4 G1 G2 G3 G4 H1 H2 H3 H4 13B-18 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Allocation of computer tracks 2 - 48-track, brown connector B (continued) Track J1 J2 J3 J4 K1 K2 K3 K4 L1 L2 L3 L4 M1 M2 M3 M4 13B 3 - 32-track, grey connector C Description Track A1 A2 A3 A4 B1 B2 Not used EGR valve position potentiometer signal Not used Damper valve solenoid valve control Not used Turbocharging pressure sensor signal Particle filter downstream temperature sensor signal Auxiliary heating relay coil 1 control Not used Not used Not used Flowmeter earth Not used UPC feed (+ BAT 2 after relay) Not used Fuel pressure regulation solenoid valve control (fuel flow actuator) B3 B4 C1 C2 C3 C4 D1 D2 D3 D4 E1 E2 E3 E4 F1 F2 F3 F4 G1 G2 G3 G4 H1 H2 H3 H4 13B-19 Description Additional heating relay coil 2 control Water in diesel detection sensor signal Not used Preheating unit diagnostic signal Not used Particle filter pressure differential sensor signal Not used Not used Not used EGR valve position potentiometer earth Refrigerant pressure sensor earth Not used Turbine upstream temperature sensor earth Not used Not used Not used Turbocharging pressure solenoid valve control Preheating unit control Particle filter downstream temperature sensor earth Turbine upstream temperature sensor supply Not used Not used Particle filter pressure differential sensor earth Not used Injector 4 feed Injector 2 feed Injector 1 control Injector 2 control Injector 1 feed Injector 3 feed Injector 4 control Injector 3 control Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Replacing components 13B COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS: The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic tool (See Technical Note 3585A). While the computer is being (re)programmed the engine fan assemblies are automatically triggered. NOTE – Switch on the diagnostic tool (mains or cigarette lighter supply). – Connect a battery charger. – Switch off all the electrical consumers (lights, interior lighting, air conditioning, audio system, etc.). – Wait for the engine to cool (engine coolant temperature < 60°°, and air temperature < 50°°). – Before the computer is reprogrammed or replaced in After-Sales, save the following data in the diagnostic tool using command SC003 "Save computer data": – the IMA codes (individual injector correction), – the engine adaptives (engine speed, and options available on the vehicle). IMPORTANT A computer without the IMA option can be replaced by a computer with this option. The codes have therefore not been saved during command SC003. In this event, status ET104 "Using injector codes" becomes "YES", fault DF276 "Injector code programming" is present, and the engine operates in defect mode. Use command SC002 "Injector code input", applying the procedure described in the interpretation of this command. After programming, reprogramming or replacing the computer: – Switch the ignition off and then on again. – Start and then stop the engine (to initialise the computer) and wait for 40 seconds. – Use the diagnostic tool to carry out the following steps: – use command SC001 "Write saved data" to re-establish the injector codes and engine adaptives, – use command VP010 "Write VIN", – deal with any faults displayed by the diagnostic tool. Clear the computer memory, – carry out a road test followed by another check with the diagnostic tool. Note: If commands SC001 and SC003 are ignored or do not work, after replacing or (re)programming the computer, write the IMA codes for each injector manually by reading the code on each injector (refer to Replacing injectors). NOTE – The injection computer retains the same immobiliser code for life. – The system has no security code. – It is prohibited to perform tests with computers borrowed from the Parts Department or from another vehicle which must then be returned. – These computers are hard-coded. – If the injection computer appears to be faulty, contact Techline and refer to the "fault finding log". 13B-20 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Replacing components 13B REPLACING THE INJECTORS: Note: The "IMA" coding (individual injector correction) is a calibration made in production on each injector to adjust its flow accurately. These correction values are etched onto the Bakelite body of each injector (6 alphanumeric characters) and then entered into the computer which then controls each injector taking into account their manufacturing variance. After one or more injectors have been changed, you must record the IMA codes again. The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool. To do this, record the "IMA" code(s) etched in the injector casings, and enter the codes in the computer using the SC002 "Enter injector codes" command, and follow the instructions given by the diagnostic tool. IMPORTANT: The letters J and Q, and figures 0 and 9 are not used in IMA coding. If these characters are used the entry will be invalid. Cylinder no. 1 is the cylinder located at the engine flywheel end. Procedure to be followed: – Read the 6-character alphanumeric codes etched on the upper section of the injector bodies. – Use command SC002. – Select the cylinder number for the cylinder concerned in the "Desired" column, then confirm. – Enter the injector code displayed for the cylinder. – Enter the new codes for each cylinder, then confirm. – When the command is completed, the modified codes appear in the "Current" column. – Check that the codes correspond to those read earlier. – If the codes entered appear in neither the "Current" column nor the "Desired" column, check the codes read and make sure the data has been entered correctly, The possible confusions are: digit "1" with the letter "I" digit "5" with the letter "S" digit "8" with the letter "B" – – – – Exit fault finding mode. Switch off the ignition and wait 40 seconds. Switch the ignition back on and check for faults. DF276 "INJECTOR CODE PROGRAMMING" should be stored. If fault DF276 is still present, the command has not been performed correctly. Start the procedure again and follow the instructions. If the codes are not always referred to, check to see if power latch* has functioned correctly: Switch off the ignition and wait 40 seconds. If the warning light flashes as soon as the ignition is switched off, the power latch* has not been performed and the command will be ignored. If all these checks still do not enable the command to be confirmed, contact Techline. *Computer on standby after switching the ignition off: approximately 40 seconds. 13B-21 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Replacing components 13B REPLACING THE EGR VALVE: After the exhaust gas recirculation valve is replaced, the computer has to store the new valve offset (at 0 miles), and the measured offset from the last time the ignition was switched off (in power latch* phase), this corresponds to the valve closing. The computer detects clogging or a blockage in the valve using this data. 1. Procedure to follow after replacing the EGR valve: – – – – – – – – – – switch on the ignition, select the "CLEAR" menu, run the clear command RZ002 "EGR adaptives", display the parameters in the "Emission control/OBD" sub-function: PR128 = PR129 = 0 %, switch off the ignition and wait 40 seconds, as soon as the ignition is switched on again the EGR valve offset is automatically reinitialised, display the parameters for the EGR circuit: 10 % < PR128 < 40 %, start the vehicle to enable the latest EGR valve offset to be programmed, switch off the ignition and wait 40 seconds, display the parameters for the EGR circuit: 10 % < PR128 = PR129 = PR051 < 40 % Clear any faults. 2. Static test: Exit fault finding mode and switch off the ignition: – – – – – – wait 40 seconds, and switch on the ignition again, clear any faults, start the engine, let the engine idle for 1 min, accelerate very slowly up to 1,500 rpm for 2 mins until the exhaust gas recirculation function becomes active, repeat this procedure 5 times. Check for faults. If the fault does not recur, end the fault finding procedure. If the fault reappears, restart the procedure after disconnecting and reconnecting the EGR valve. If the fault is still present, replace the EGR valve. Carry out a vehicle test at low-speed, without accelerating heavily, then normally. Check for faults using the CLIP diagnostic tool. If the fault does not recur, end the fault finding procedure. If the fault reappears, restart the procedure after disconnecting and reconnecting the EGR valve. If the fault is still present, replace the EGR valve. *Computer on standby after switching the ignition off: approximately 40 seconds. 13B-22 Edition 2 EDC16 PROGRAM no.: C1 Vdiag no.: 50 DIESEL INJECTION Fault finding - Replacing components 13B REPLACING THE PARTICLE FILTER: After replacing the particle filter, reconfigure the computer.

Impact detected If an impact has been stored by the injection computer. Role of components. then switch it back on so that the engine can be started. the injection computer and the UCH exchange authentication data via the multiplex network. Each inter-system (ESP and automatic gearbox) sends a request for torque via the multiplex network to the injection computer. The torque structure uses the torque setpoint to calculate the throttle position setpoint. this determines whether the engine start is authorised. If this fails again. It arbitrates between the inter-system torque requests and the driver's request (pedal or cruise control/ speed limiter).System operation 17B 2. switch off the ignition for 10 seconds. the engine management computer goes into protection (anti-scanning) mode and no longer tries to authenticate the UCH computer. : AD Vdiag No. This is the case on engines that do not have a camshaft dephaser. It is based on torque analysis. a second program confirms the first decision. the throttle position is regulated according to the idling speed setpoint. This information can be viewed through status ET084 Camshaft dephaser. The camshaft dephaser is continuously variable in operation. This setpoint takes into account the major power consumers (air conditioning) and operating conditions (air temperature and coolant temperature). Motorised throttle valve The throttle valve carries out idling speed regulation and engine air inlet modulation functions. – checks the position of the inlet camshaft. A first strategy called "Memo phasing" is applied to phase the engine management on starting according to the data recorded when the engine last stalled. It is composed of an electric motor and two throttle position potentiometers. The injection computer actuates a camshaft dephaser that varies according to the engine: – K4M engine Continuous variable inlet camshaft dephaser between 0 and 43°° of the crankshaft. controlled by a solenoid valve supplied by an opening cyclic ratio circuit through the injection computer. the engine phasing is controlled by software. 17B-10 .

Adaptive corrections take 50% as an average value after computer initialisation (clearing the programming) and have the following limit values. Richness regulation is controlled by the upstream sensor. any power assisted steering action. the voltage supplied to the computer represents a Rich . The richness correction value PR138 Richness correction value is around 50%.Poor signal. Calculation for setting the idling speed: The idling speed setpoint is given by parameter PR010 Idle speed regulation valve setpoint. The richness adaptive corrections PR143 Self-adapting richness gain and PR144 Self-adapting richness offset are used to offset the injection mapping to centre richness regulation on 50%. The sensor gives voltage according to the difference between the partial oxygen pressures contained in the exhaust and a cavity filled with a reference mixture (atmosphere). 1 minute after starting the engine and during the idle speed regulation phase. the position of the gearbox selector. the idling speed opening cyclic ratio value PR091 Idling speed regulation theoretical OCR varies between a high value and a low value to obtain the nominal idling speed. The idling speed regulation setpoint depends on the coolant temperature. the air conditioning requirements. As the partial oxygen pressure in the exhaust is representative of the richness. the passenger compartment heating resistors. the richness regulation corrects the injection timing so as to obtain a metering as close as possible to richness 1. This adjustment only takes effect if the coolant temperature is above 75°°C. The adaptive correction PR090 Idle speed regulation programming value on the idle speed opening cyclic ratio enables the engine's air requirement to be slowly varied. the richness must be maintained around 1.

The misfiring and fuel supply system fault finding is performed continuously. turbocharging pressure. canister bleed. ignition coil 2. ● the OBD fault warning light receives a request to be lit continuously. The more the catalytic converter is degraded. then the average taken. The fault finding check may be staggered. divided over several consecutive engine stability phases. If the catalytic converter is in good condition it will absorb the oxygen sent to it and the downstream sensor voltage will remain at its average value. As the catalytic converter ages. ● chemical or thermal damage to the component leading to a slower response time of the sensor and to the increase in the average rocking time. richness excitation peaks are applied. it rejects the oxygen that it cannot store and the downstream sensor starts knocking. There are 2 kinds of oxygen sensor damage: ● mechanical damage to the component (breakage. and its duration will vary according to the condition of the sensor.System operation 17B Catalytic converter: Objective Catalytic converter fault finding should detect a malfunction which would cause hydrocarbon pollutant emissions to exceed the EOBD (European On Board Diagnostic) limit. The principle lies in using the correlation between the oxygen storage capacity and the HC emissions. its ability to store oxygen reduces along with its ability to treat pollutants. Principle The ability of the catalytic converter to store oxygen indicates the condition of the catalytic converter.: 4C PETROL INJECTION Fault finding . If it is degraded. i. When the conditions for starting fault finding are confirmed. and compared with an EOBD (European On Board Diagnostic) limit average period. which has the effect of sending bursts of oxygen into the catalytic converter. the upstream sensor signal periods are read and the glitches (interference phenomena) removed.
