Principles of Operation: Notes

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.

The Body Control Module (BCM) controls various systems by monitoring inputs from switches, sensors and messages sent from other modules. Based on the inputs received, the BCM activates outputs. For example, the SCCM monitors the headlamp switch and transmits the headlamp switch position to the BCM over the network. Based on this input, the BCM may provide voltage to the exterior lamps.
