Malfunction Indicator Lamp (MIL) Check

Malfunction Indicator Lamp (MIL) Check

1. Turn ON ignition switch (but the engine at stop) and check that MIL lights. If MIL does not light up (or MIL dims) but engine can be started, go to Malfunction Indicator Lamp Does Not Come ON with Ignition Switch ON and Engine Stop (but Engine Can Be Started) for troubleshooting.
If MIL does not light with ignition switch ON and engine does not start though it is cranked up, go to ECM Power and Ground Circuit Check.




2. Start engine and check that MIL turns OFF. If MIL remains ON, and no DTC is stored in ECM, go to Malfunction Indicator Lamp Remains ON after Engine Starts for troubleshooting.
