Malfunction Indicator Lamp: Testing and Inspection




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.
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.
