Normal Operation

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster receives engine data from the powertrain control module (PCM) over the communication network. If a DTC is set by the PCM, the MIL illuminates.
