Malfunction Indicator Lamp: Description and Operation

Malfunction Indicator Lamp (MIL)
1. The malfunction indicator lamp will light up when the ignition switch is turned ON without the engine running. This is a bulb check.
- If the malfunction indicator lamp does not light up, inspect malfunction indicator bulb or circuit.
2. When the engine is started, the malfunction indicator lamp should go off.
If the lamp remains on, the on-board diagnostic system has detected an engine system malfunction.
