Gateway Module
WARNING: This page is about a different car, the 2014 Ford F-550 Super Duty, 2014 Ford F-450 Super Duty, 2014 Ford F-350 Super Duty, and 2014 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The Body Control Module (BCM) is the gateway module, translating messages on the HS-CAN to MS-CAN and vice versa. This allows a message to be distributed throughout both networks.
Vehicles equipped with the premium audio system with touchscreen use an I-CAN network. The IPC is the gateway module, translating messages on the HS-CAN to the modules on the I-CAN , and vice versa. This allows messages to be distributed throughout both networks, if required.
The BCM and IPC are the only modules on this vehicle that have this ability.
