Test A-2: Malfunction Indicator Light (Mil) Remains Illuminated

NOTE: With ignition on, PCM energizes main relay. As PCM is supplied ignition power, MIL illuminates. After engine starts, MIL turns off if no malfunction is detected. If a malfunction is detected, MIL will remain illuminated until system is repaired.
  1. Connect scan tool to Data Link Connector (DLC). Turn ignition on, engine off. Attempt to retrieve DTCs. If any DTCs are displayed, see DIAGNOSTIC TESTS  . If no DTCs are displayed, go to next step.
  2. Start engine. Attempt to retrieve DTCs. If no DTCs are displayed, turn ignition off. Disconnect PCM harness connectors. Turn ignition on. If MIL illuminates, repair short to ground in Purple/Yellow wire between MIL bulb and PCM harness connector. If MIL does not illuminate, replace PCM and retest system.
