WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Power Steering Controls for schematic and connector information.

Normal Operation and Fault Conditions 

There are 2 power sources for the PSCM, the high current power steering fuse, and the low current power steering fuse. Refer to the wiring diagrams to review the PSCM circuit for both the high current and low current fuse locations as well as the associated power and ground wiring. Open power steering fuse can occur when the power or ground wiring is shorted against another component or water intrusion in the respective connectors or connections.
