Fail-Safe Chart
- When the DTC listed below is detected, the ECM enters fail-safe mode and the MIL lights up.
- When there is an open circuit on MIL circuit, the ECM can not warn the driver by lighting MIL up when there is malfunction on engine control system.
Therefore, when Electrical controlled throttle and part of ECM related diagnoses is continuously detected as NG for 5-trips, ECM warns the driver that engine control system has malfunction and MIL circuit is open by means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected, and demands the driver to repair the malfunction.
