Fail-safe Chart
WARNING: This page is about a different car, the 2005 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
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 cannot warn the driver by lighting up 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 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.
FAIL-SAFE FUNCTION
