Malfunction Indicator Lamp: Testing and Inspection

1. Turn ON ignition switch (but the engine at stop) and check that MIL lights.
If MIL does not light up or dims, go to "MIL Does Not Come ON or MIL Dims at Ignition Switch ON Leaving Engine OFF" for troubleshooting.
2. Start engine and check that MIL turns OFF.
If MIL remains ON, and no DTC is stored in ECM (PCM), go to "MIL Remains ON after Engine Starts" for troubleshooting.
