System Operation: BCM

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The BCM controls various systems by monitoring inputs from switches, sensors and network messages from other modules and components on the HS-CAN1, MS-CAN, LIN and K-LINE. Based on these inputs, the BCM activates outputs. For example, the BCM monitors the HCM input. Based on this input, the BCM may provide voltage to the exterior lamps.
