Normal Operation

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) receives a vehicle speed signal from the transaxle control module (TCM). The PCM then sends the vehicle speed signal through the controller area network (CAN) circuit 1908 (WH) and circuit 1909 (BK) to the power steering control module.
