Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Gateway Module
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.
