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 cannot warn the driver by lighting MIL up when there is a malfunction on engine control system.
Therefore, when electrically controlled throttle and part of ECM related diagnosis is continuously detected as NG for 5 trips, ECM warns the driver that engine control system has a 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.
FAIL-SAFE FUNCTION
| Engine operating condition in fai-safe mode | Engine speed will not rise more than 2,500 rpm due to the fuel cut |
