Check Engine Light: Notes

All vehicles are equipped with a CHECK ENGINE light located on the instrument panel. Light will come on, as a bulb check, when ignition switch is in ON position and engine is not running. Light should go out when engine is started.

When the CHECK ENGINE light remains on or flashes with the engine running, the self-diagnostic system has detected a problem. If the problem goes away, the light will go out after 10 seconds, but a trouble code will remain stored in the Electronic Control Module (ECM) memory.
