Malfunction Indicator Lamp (MIL)

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The MIL informs the driver that the PCM has detected an OBD emission-related component or system concern.

The MIL is located in the IPC and is the ISO (international standards organization) 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 OBDDTC exists.
To turn off the MIL after a repair, a clear DTC command from the scan tool must be sent to the PCM.
For any MIL concern, Refer to the PCM Quick Test.
