Component Description: BCM
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The BCM is the gateway module, translating messages on the High Speed Controller Area Network (HS-CAN) to Medium Speed Controller Area Network (MS-CAN). This allows a message to be distributed throughout both networks.
