SCOPE OF THIS DOCUMENT This document describes the diagnostics applicable to all Central Processing Units with the following characteristics: Vehicle(s): SCENIC II Function concerned: AUTOMATIC TRANSMISSION Name of computer: Siemens TA 2000 Program no.: 94 VDIAG No.: 10 2. PREREQUISITES FOR FAULT FINDING Standard documentation: Fault finding procedures (this manual): – Assisted fault finding (incorporated into the diagnostic tool), paper version (Workshop Repair Manual or Technical Note) and Dialogys. Wiring Diagrams: – Visu-Diagram (CD-ROM), paper. Type of diagnostic tools: – CLIP Special tooling required: Special tooling required Multimeter. Elé. 1681 Elé. 1588 3. REMINDERS Procedure: To run diagnostics on the vehicle's computers, switch on the ignition in fault finding mode (+ after ignition forced setting). Proceed as follows: – Renault card on the card holder (keyless vehicle scenario 1, basic, not hands-free and scenario 2, top of the range, hands-free), – Press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled. – Then connect the fault finding tool and perform the required operations. Note: The left and right-hand Xenon bulb computers are supplied when the dipped headlights are lit. Fault finding procedures can only be carried out on them after the ignition has been switched on in fault finding mode (+ after ignition imposed) and the dipped headlights are on. To cut off + after ignition, proceed as follows: – Disconnect the fault finding tool. – Press the Start button twice briefly (less then 3 seconds). – See that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument panel have gone out. Universal terminal Terminal DP094101.0 23A-2 SIEMENS TA2000 PROGRAM No.: 94 VDIAG No.: 10 AUTOMATIC GEARBOX Fault finding - Introduction 23A Faults: Faults are declared to be either present or stored (depending on whether they appeared in a certain situation and have disappeared since, or whether they remain but are not diagnosed within the current context). The present or stored status of faults must be considered when using the diagnostic tool after switching on + after ignition (without activating the system elements). Deal with present faults according to the procedure specified in the section on "Interpretation of faults". For a stored fault , note the faults displayed and follow the instructions shown in the "NOTES" section. If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. In this case, 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 faulty component, – the condition of the wires (melted or cut insulation, wear). Conformity check The conformity check is designed to check the states and parameters which do not display any faults on the diagnostic tool when inconsistent. This phase therefore permits: – Fault finding on faults which are not displayed but which may correspond to a customer complaint. – Checks that the system operates correctly and that there is no risk of a fault reappearing after repairs. This section gives the fault finding procedures for states and parameters and the conditions for checking them. If a state 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 check using the diagnostic tool is satisfactory, but the customer complaint is still present, the problem should be treated as a customer complaint. A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

FAULT FINDING LOG WARNING All problems involving a complex system call for thorough diagnostics with the appropriate tools. The FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a record is kept of the procedure carried out. It is an essential item when discussing the fault with the constructor. WARNING! IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING SHEET EACH TIME FAULT FINDING IS DONE. You will always be asked for this log: q When requesting technical assistance from the Techline. q For certification requests when replacing parts that must be certified. q Which must be attached to monitored parts for which reimbursement is requested. It is therefore used to decide whether a reimbursement will be made under warranty and leads to improved analysis of the removed parts. 6. SAFETY INSTRUCTIONS All work on components requires that the safety rules be obeyed to prevent damage or injury: – Make sure the battery is properly charged to avoid damaging the computers with a low charge. – Use the proper tools. 7.

Check the power circuit of the starter relay and the starter. Carry out a fault finding procedure on the injection system. AFTER REPAIR Perform a complete check using the diagnostic tool. DP094101.0 23A-115 SIEMENS TA2000 PROGRAM No.: 94 VDIAG No.: 10 AUTOMATIC GEARBOX Diagnostic - Fault finding charts 23A CHART 3 Automatic transmission operating problem NOTES Consult the fault finding charts only after carrying out a diagnostic using the diagnostic tool and after completing the conformity check. Using the diagnostic tool, check the consistency between the display and the selector lever positions (ignition on and engine stopped). Adjust the controls following the instructions in the Technical Note. Check oil level and condition (colour, odour, etc.). If the oil condition suggests an internal problem, replace the automatic transmission. With the engine stopped, check the line pressure information supplied by the oil pressure sensor. Replace the sensor if the pressure signal is > 0.2 bar. Fit a pressure gauge to the pressure measurement tapping on the transmission housing (make sure the oil temperature is greater than 20˚C before continuing). Note the line pressure indicated by the pressure gauge and by the diagnostic tool in the following conditions: – With the brakes on, gearshift in "D" and engine speed = 1200 rpm. Replace the pressure sensor if the gauge and diagnostic tool readings differ. Repeat the check after replacement. Transmission oil temperature between 60˚C and 90˚C, brakes applied and gearshift in "D", place a pedal press or a stop on the accelerator pedal to get a stable reference pressure of approximately 8 bar (engine speed of approximately 1300 rpm). Note the pressure gauge and diagnostic tool readings obtained under these conditions, while ensuring that the engine speed remains stable between both readings. These measurements must be carried out rather quickly so that these conditions do not have to be maintained for too long. Replace the pressure modulating solenoid valve and the oil if the difference between the two readings is more than 0.5 bar. Repeat the check after replacement. If the fault persists, replace the hydraulic distributor and all the solenoid valves. Start the engine. With the brakes applied, move the selector lever into position "D" and accelerate, observing the turbine speed signal. If the turbine speed signal changes, replace the gearbox. AFTER REPAIR Perform a complete check using the diagnostic tool. DP094101.0 23A-116 SIEMENS TA2000 PROGRAM No.: 94 VDIAG No.: 10 AUTOMATIC GEARBOX Diagnostic - Fault finding charts 23A Chart 3 (CONTINUED ) Refer to the procedure and the safety instructions for carrying out a setting point check on the torque converter. Theoretical engine speed at setting point: 2300 ± 150 rpm. If the setting point value is incorrect, replace the torque converter, converter lock-up solenoid valve, and oil. If the oil is burnt, also replace the hydraulic distributor and all the solenoid valves. When replacing the torque converter, ensure that the reaction shaft is securely attached to the hub of the oil pump (flanged shaft). Note: a setting point which is too low may be linked to a lack of engine power. Carry out a road test, observing the engine speed on the instrument panel and the displays on the diagnostic tool. If the engine speed does not vary with each change of gears, replace the hydraulic distributor and all the solenoid valves. AFTER REPAIR As a final step, clear the stored faults with command RZ004 "Clear stored faults", the computer self-adapters with command RZ005 "Self-adapter" and the converter adapters with command RZ006 "Converter lock-up adapter". See the "System operation and track allocation" section for how to reset the oil aging counter to zero (enter gearbox oil change date). DP094101.0 23A-117 SIEMENS TA2000 PROGRAM No.: 94 VDIAG No.: 10 AUTOMATIC GEARBOX Diagnostic - Fault finding charts 23A CHART 4 Automatic transmission malfunction when changing gears NOTES Consult the fault finding charts only after carrying out a diagnostic using the diagnostic tool and after completing the conformity check. The automatic transmission may show malfunctions during gear changing without any fault being stored in the computer. These malfunctions may be due to contact resistance problems on the control lines of the sequence and sequence solenoid valves (EVS1 to EVS6) preventing the self-diagnostic system from detecting a fault in the solenoid valve or preventing the solenoid valves from being controlled. Check the clamping action and condition of the clips on all the connections to the solenoid valve control lines (from the computer to the solenoid valve). AFTER REPAIR Perform a road test, then do a complete check with the diagnostic tool.

Do a road test with the CLIP fault finding tool, making sure that status ET013 "Gear engaged" functions normally. If the customer complaint occurs when the brake pedal is released, check that status ET142 "Brake pedal pressed" really is NO. Otherwise adjust the brake light switch and brake pedal return spring. Make sure the instrument panel display of the gear engaged matches the gearshift position. Check the path of the automatic transmission harness (interference or high voltage problem). Change it if necessary. Check the adjustment of the external control. If the fault persists, replace the multifunction switch. Carry out a fault finding procedure on the injection system. Check the PR006 "Engine speed" signal during a road test at a steady speed. If the signal is wrong, replace the engine speed sensor. AFTER REPAIR Perform a road test, then do a complete check with the diagnostic tool.
