Gateway Function

The BCM acts as a gateway module by receiving information in one format and transmitting it to other modules using another format. For example, the BCM receives the vehicle speed data from the RCM over the High Speed Controller Area Network (HS-CAN), converts the data into a Medium Speed Controller Area Network (MS-CAN) message and sends (gateways) the message to other network modules such as the IPC module. This enables network communication between modules that do not communicate using the same network (High Speed Controller Area Network (HS-CAN) or Medium Speed Controller Area Network (MS-CAN)).
