Fail-Safe Chart

Fail-safe Chart

When the DTC listed below is detected, the ECM enters fail-safe mode and the MIL lights up.

P0102-P2138:

- When there is an open circuit on MIL circuit, the ECM cannot warn the driver by illuminating MIL when there is malfunction on engine control system.

Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means of operating the 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.
