Malfunction Indicator Lamp (MIL)
WARNING: This page is about a different variant/trim than selected.
The MIL notifies the driver the PCM has confirmed an on board diagnostic (OBD) emission related component or system concern. When this occurs, an OBD DTC sets.
- The MIL is located in the instrument panel cluster (IPC) and the international standards organization (ISO) standard engine symbol.
- The MIL is illuminated with the ignition ON, engine OFF, until the engine is cranked for starting. The MIL will turn OFF after engine start if no concerns are present.
- The MIL may flash after 17 seconds with the ignition ON, engine OFF, unless the OBD inspection/maintenance (I/M) readiness indicators indicate all of the OBD monitors have completed since the last keep alive memory (KAM) reset or since the PCM DTCs have been cleared with a reset command from the scan tool.
- The MIL will remain illuminated after engine start if a confirmed emission related concern or an OBD DTC exists.
- If the MIL flashes at a steady rate, after engine start, a severe misfire condition may exist.
- The MIL will remain OFF with the ignition ON, engine OFF, if a MIL indicator or IPC concern is present.
- To turn OFF the MIL after a repair, a reset command from the scan tool must be sent, or 3 consecutive drive cycles must be completed without a concern.
- If the MIL flashes erratically, a low battery voltage concern may be present causing the PCM to reset during cranking.
- For all MIL concerns, go to SYMPTOM CHARTS .
