Malfunction Indicator Lamp (MIL) DTCs

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

MIL DTCs are generated to alert the driver that there is a concern with the system or the vehicle is in failure management effects mode (FMEM). MIL DTCs are also used to indicate an emission concern. Non-MIL DTCs indicate a less serious or non-emission related concern with the system.
