System Operation: BCM

The BCM controls various systems by monitoring inputs from switches, sensors and network messages from other modules and components on the HS-CAN, MS-CAN, LIN and the GWM. Based on these inputs, the BCM activates many outputs. For example, the BCM monitors the HCM inputs and provides voltage to the exterior lamps. Or the DCMH to provide power and ground for the sliding door latch.
