Malfunction Indicator Light (Mil): Notes

NOTE: MIL is also known as the CHECK ENGINE light.

All vehicles are equipped with a Malfunction Indicator Light (MIL), located on instrument panel. Light comes on, as a bulb check, when ignition switch is turned to ON position and engine is not running. Light should not flash at this time and should go out when engine is started.

If MIL remains on or flashes with engine running, self-diagnostic system has detected a problem. If problem goes away, light will go out after 10 seconds, but a fault code will be stored in ECM memory.
