System Operation: BCMC

The BCMC may be referred to as a BJB or a PDB (power distribution box). The BCMC controls various systems by monitoring inputs from switches, sensors and network messages from other modules and components on the HS-CAN1. Based on these inputs, the BCMC activates outputs. For example, the BCMC controls the A/C clutch control relays, horn relay and upfitter relays.
