Gateway Module
The Body Control Module (BCM) and Instrument Panel Cluster (IPC) are the gateway modules. The BCM translates messages on the HS-CAN to the MS-CAN and vice versa. The IPC translates messages on the HS-CAN to the I-CAN and vice versa. This allows a message to be distributed through all three networks. The BCM and IPC are the only modules on this vehicle that have this ability.
