IC Gateway Function

WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The IC  acts as a gateway module by receiving information in one format and transmitting it to other modules using another format. For example, the 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 HVAC, 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  ).
