Body Control Module (BCM)
| Refer to COMPONENT INDEX . |
The BCM is one of two gateways on this vehicle with the other being the Security Gateway Module. The BCM converts several CAN-Flexible Date (CAN-FD) and CAN-Chassis1 (CAN-C1) messages between the networks that allows other modules on this vehicle to communicate with each other.
The BCM is responsible for transmitting IPC screen display status requests over the CAN-C and also transmits that the NVPM is present on the CAN-FD.
