Inspection Procedure 20: AS&G System Abnormal (auto start not carried out)

caution

If the following motions are carried out during the auto stop even one time, the engine-ECU blinks the AS&G display screen in the combination meter and prohibits the auto start. Even if trying to return to the previous status after that, the auto start is prohibited. When restarted, the engine must be started by the key.

In case the hood is opened

FUNCTION

When the driver depresses the clutch pedal <M/T> or the brake pedal <CVT> during the auto stop, the engine-ECU will restart the engine.

COMMENTS ON TROUBLE SYMPTOM
