Check Engine Light: Notes

All vehicles are equipped with a CHECK ENGINE light, 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 CHECK ENGINE light 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.
