WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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 on-board diagnostics (OBD) emission-related component or system concern.
- The MIL is located in the instrument panel cluster.
- The indicator is illuminated by a PCM message sent through the controller area network (CAN) to the instrument panel cluster.
- An engine or transmission with federal calibration operating in the failure mode effects management (FMEM) may cause the MIL to illuminate.
- 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, Refer to Section 3, GO to QUICK TEST QT1 , Powertrain Control Module (PCM) Quick Test.
