Gateway Module
WARNING: This page is about a different car, the 2011 Ford RV Cutaway, 2011 Ford Econoline, 2011 Ford E450 Super Duty, and 2011 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The Instrument Panel Cluster (IPC) is the gateway module, translating messages on the High Speed Controller Area Network (HS-CAN) to the Medium Speed Controller Area Network (MS-CAN) and vice versa. This allows a message to be distributed throughout both networks.
The IPC is the only module on this vehicle that has this ability.
