Instrument Cluster (IC) Gateway Function

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster (IC) acts as a gateway module by receiving information in one format and transmitting it to other modules using another format. For example, the instrument cluster (IC) receives the vehicle speed data from the PCM over the HS-CAN, converts the data into a MS-CAN message and sends (gateways) the message to other network modules such as the heating ventilation air conditioning (HVAC) module, the audio control module (ACM), the parking aid module (PAM), the restraints control module (RCM) and the SJB. This enables network communication between modules that do not communicate using the same network (HS-CAN or the MS-CAN).
