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 starting, go to Malfunction Indicator Lamp Does Not Come ON with Ignition Switch ON (But Engine Stops):M13A with VVT for troubleshooting.
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:M13A with VVT for troubleshooting.
