Check Engine Light

All models are equipped with a CHECK ENGINE light. As a bulb check, light will illuminate when the ignition is on and engine is not running. CHECK ENGINE light will also illuminate when a system failure has been detected, and a corresponding trouble code has been set in ECU memory. See RETRIEVING CODES .

Not all trouble codes will activate CHECK ENGINE light. If CHECK ENGINE light is on and no codes are flashed by LED on ECU, this indicates that back-up system is in operation. See TESTS W/O CODES article.
