WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When any of these DTCs are set the PSCM will remove steering assist, enter into a manual mode and transmit an invalid steering column torque message over the HS-CAN bus.
The PSCM will send a message to the IPC to display the POWER STEERING ASSIST FAULT message in the message center.
