DTC Troubleshooting Index

Symptom Troubleshooting Index

If the vehicle has one of the symptoms below, check for a diagnostic trouble code (DTC) with the HDS. If there is no DTC, do the diagnostic procedure for the symptom.

Scheme 6

Scheme 7

Scheme 8

The IMA (integrated motor assisted) system is a highly-efficient parallel hybrid drive system with a main power unit (gasoline engine) and an assist unit (electric motor).

The engine is an in-line, 4-cylinder, 8-valve power plant with a displacement of 82 cu. in (1.339 liters). To reduce fuel use, the engine is equipped with i-DSI and a valve pause system that reduces engine pumping loss and increases the generation of electric energy during deceleration.

The IMA motor, directly connected to the engine crankshaft, functions as a generator during deceleration, an engine starter, and a motor to assist the engine that drives the wheels.

The IMA system contains a 100 V DC battery, a control system, and related parts. For safety, the intelligent power unit (IPU) is located under the cargo compartment.

The IMA system improves fuel economy by capturing and storing energy during deceleration.

Scheme 9

Scheme 10

1. Engine start: The IMA system drives the IMA motor and starts the engine during normal starts and when re-starting from an idle stop. The IMA motor is linked directly to the engine crankshaft.
2. Start running: The IMA motor assists the engine.
3. Slow acceleration: Runs only with the engine.
4. Low speed cruise: At a constant speed of about 25 mph (40 km/h) with light toad, all engine cylinders are deactivated, and the vehicle runs only with the IMA motor. When the state-of-charge (SOC) drops, the engine starts and the IMA motor begins to charge the battery module.
5. Acceleration: The IMA motor assists the engine.
6. High acceleration: The IMA motor assists the engine.
7. High speed cruise: Runs only with the engine. When the state-of-charge drops, the IMA motor begins to charge the battery module.
8. Deceleration: All engine cylinders are deactivated, and the IMA motor captures the deceleration energy and charges the battery module.
9. Stop: When conditions are satisfied, the PCM stops the engine automatically (auto stop).

Auto Idle Stop System Inspection

1. Check under these conditions: At 2.500 m (8, 200 ft) or less altitude (At higher altitudes, auto idle stop is often prevented because of the lack of vacuum in the brake booster). The low temperature indicator is off. The IMA battery level indicator displays at least half full. Climate control off. All electrical items (headlights, blower fan, radiator fan, rear window defogger, A/C, etc.) are off. The transmission is in D. The D indicator is not flashing. No heavy load in the vehicle (A heavy load prevents auto idle stop because the system "thinks" the vehicle is going uphill). Drive the vehicle on a flat road or downhill.
2. Start the engine.
3. Test-drive under these conditions: Drive the vehicle at 25 mph (40 km/h), then stop it within 5-15 seconds. Press and hold the brake pedal until the vehicle stops (Do not pump the brake pedal). Keep the brake pedal pressed after the vehicle stops.
4. Repeat step 3 several times. Is auto idle stop working? YES -The system is OK at this time. If needed, refer to «AUTO IDLE STOP CONDITIONS»(ref-513150-S19303202652012110700000) . NO -Go to the «AUTO IDLE STOP SYSTEM TROUBLESHOOTING»(ref-513150-S13585272892012110700000) .
