Be sure to shut off the electrical circuits and isolate the IMA system and related parts before servicing the IMA system. • The high voltage cables and their covers are identified by orange coloring. The caution labels are attached to high voltage and other related parts (see page 1-5). Be careful not to touch these cables and parts without adequate protective gear. The front floor under-cover protecting the high voltage cables is marked . • If the 12 V battery has been discharged, or its cable has been disconnected, or the MCM (motor control module) has been reset, the IMA battery level gauge (BAT) will not display the state of charge when the engine is started. Start the engine, and hold it between 3,500 rpm and 4,000 rpm without load (in Park or neutral) until the level gauge (BAT) displays at least three segments. • Observe the following instructions when inspecting or servicing the IMA system. – When the IMA system indicator is on, do the IMA system troubleshooting first (see page 12-5). – Wear insulated gloves whenever you inspect or service the IMA system. Be sure to check the gloves for pin holes, tears, or other damage. – Turn the battery module switch OFF, and secure the switch in the OFF position with the locking cover before servicing the IMA system (see Turning off power to the high voltage circuit). – Wait for 5 or more minutes after turning off the battery module switch, then disconnect the negative cable from the 12 V battery (it takes about 5 minutes for the PDU capacitor to discharge). – Before disconnecting the high voltage cable terminals, make sure that the voltage between the terminals is below 30 V when measured with a voltmeter. • When servicing the parts without the insulating sheath, be sure to use the insulated tools to prevent short circuiting. • The rotor assembly contains very strong magnets and should be handled with special care. People with pacemakers or other magnetically sensitive medical devices should not handle the rotor assembly. If the rotor is installed by hand, it may suddenly be pulled toward the stator with great force causing serious hand or finger injury. Always use the special tool to remove or install a rotor assembly. • Keep the rotor assembly away from magnetically sensitive devices. • After disconnecting the high voltage terminals, busbars, etc., insulate the parts with insulated tape. • As a safety warning, attach a sign saying, ‘‘WORKING ON HIGH VOLTAGE PARTS. DO NOT TOUCH!’’ to the steering wheel. Disconnecting the motor power cable connector from the motor stator Slide the protector (A) in the direction of the arrow. Push the tab (B), then raise the lever (C). Remove the motor power cable (D) from the motor startor. NOTE: • If the motor power cable connector is dirty, clean it. • Cover the disconnected connector (E) with a plastic bag (F), and wrap the motor power cable terminals with tape (G). • If the motor power cable is wet, wait until it is dry. *01 G B A C E D F • Use the special tool to remove or install the rotor assembly. (cont’d) 12-3 SNC7A00A26400000000BAAT10 There should be 30 V or less. The following procedure should be performed prior to working on or near any high voltage components. make sure all the high voltage circuits are connected properly. • Before the battery module switch is turned ON.

The IMA motor is directly connected to the engine crankshaft, so it is quieter than the 12 V starter. If a problem occurs with IMA system, for example, low battery module state of charge (SOC), low temperature, faulty IMA system, etc. The PCM receives a signal from the MCM and starts the engine with the 12 V starter. 09 MCM ENGINE BATTERY MODULE IMA MOTOR Motor assisting function During acceleration, energy is supplied from the battery module to the IMA motor, and the motor generates a maximum torque of 103 N·m (10.5 kgf·m, 76 lbf·ft) to assist the engine. The PCM and MCM communicate to control the assist to maintain the battery module SOC within a specified range. When the battery module SOC is below the specified range, the MCM stops the assist to prevent over-discharge or damage to the battery. Assist is also not available when the IMA battery is very cold or very hot. 10 MCM ENGINE IMA MOTOR BATTERY MODULE Regenerative control (at deceleration) During deceleration, the IMA motor, driven by the wheels, functions as a generator. It charges the battery module by generating electrical energy. This is done by converting the kinetic energy of the vehicle during braking into electric energy that is stored in the IMA battery. When the battery module is full, regeneration stops to prevent overcharge of the battery. 11 MCM ENGINE IMA MOTOR 12-22 BATTERY MODULE 06/09/19 11:26:41 61SNC010_120_0023 Auto Idle Stop System The auto idle stop system stops the engine automatically when the vehicle comes to a stop to reduce overall fuel consumption and minimize tailpipe emissions. Refer to the chart to see the conditions when auto idle stop occurs and when it does not occur. Idle stop occurs: • When the vehicle is driven above 7 mph (12 km/h) in D position, and then decelerated with the brake pedal pressed (operation speed varies depending on the conditions). • When the vehicle is driven above 7 mph (12 km/h) in D position after restart from auto idle stop, and then decelerated with the brake pedal pressed. Under this condition, idle stop happens only twice. Idle stop does not • When the vehicle stops suddenly by sharp application of the brake pedal. occur: • When the engine coolant temperature is low. • When the climate control unit prohibits the engine from stopping. 1 • When the PCM (CVT system) prohibits the engine from stopping. 2 • When the IMA battery state of charge is low. • When the IMA battery module temperature is low. • When the electric load on the 12 V system is high. • When the accelerator pedal is pressed. • When the windshield defrost button is pressed. • When a fault is detected in a related system. 3 1: With the ambient temperature at 5 °F ( −15 °C) or below. 2: When the CVT fluid temperature is low. 3: PGM-FI system, IMA system, CVT system, A/C system, etc. The PCM restarts the engine by signalling the MCM to drive the IMA motor and by restarting fuel injection. Refer to the chart to see the conditions of engine restart. Engine restart occurs: • • • • • When the brake pedal is released. When the shift lever is moved from the N to R, or D to L position. When the accelerator pedal is pressed. When the engine coolant temperature is low. When the IMA battery state of charge is low.
