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