Check Engine Light

All models are equipped with a CHECK ENGINE light. As a bulb check, light illuminates when ignition is on and engine is not running. CHECK ENGINE light also illuminates when a system failure has been detected and a corresponding trouble code has been set in ECU memory. Not all trouble codes will activate CHECK ENGINE light. If the CHECK ENGINE light is on and no codes are in memory, refer to the TESTS W/O CODES article in this section.
