WARNING: This page is about a different car, the 2020 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When this DTC is set, the PSCM removes steering assist, enters into manual mode and transmits an invalid steering angle message over the HS-CAN. The module also sends a message to the IPC to display POWER STEERING ASSIST FAULT in the message center.
