Malfunction Indicator Lamp (MIL)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
The MIL informs the driver that the powertrain control module (PCM) has detected an OBD emission-related component or system concern. When this occurs on a California-calibrated engine, an OBD diagnostic trouble code (DTC) is set. On a federal calibrated engine and transmission, certain concerns also illuminate the MIL.
- On all vehicles, the MIL is located in the instrument cluster.
- The indicator is illuminated by a PCM message sent through the controller area network (CAN) to the instrument cluster.
- An engine or transmission with federal calibration operating in the failure mode effects management (FMEM) may cause the MIL to be illuminated.
- 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 the SYMPTOM CHARTS article PCM Quick Test.
