High Speed Controller Area Network (CAN)
WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The high speed CAN has an unshielded twisted pair cable, data plus circuit 1908 (WH) and data minus circuit 1909 (BK). The high speed CAN is a high speed communications network used for the anti-lock brake system (ABS) module, the differential electronic module (DEM) (if equipped), the transmission control module (TCM) - 6-speed transaxle, TCM - continuously variable transaxle (CVT), the instrument cluster, the powertrain control module (PCM) and the restraint control module (RCM) communication.
On the high speed CAN, there are 2 terminating modules which are composed of the PCM and the instrument cluster.
