IPC Gateway Function
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The IPC acts as a gateway module by receiving information in one format and transmitting it to other modules using another format. For example, the IPC receives the vehicle speed data from the PCM over the HS-CAN , converts the data into an MS-CAN message and sends (gateways) the message to other network modules such as the HVAC module, the Audio Control Module (ACM) and the SJB . This enables network communication between modules that do not communicate using the same network (HS-CAN or the MS-CAN ).
