The MIL informs the driver that the PCM has detected an on-board diagnostics (OBD) emission-related component or system concern.
- The MIL is located in the instrument panel cluster (IPC) and is 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 will remain illuminated after engine start if a confirmed emission related concern or an OBD DTC exists.
- To turn off the MIL after a repair, a clear DTCs command from the scan tool must be sent to the PCM.
- For any MIL concern, GO to QUICK TEST QT1, Powertrain Control Module (PCM) Quick Test.
