WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
For DTC U3000:41, the PSCM disables steering assist, enters manual mode and transmits an invalid steering angle message over the HS-CAN. The module also sends a message to the instrument cluster to display POWER STEERING ASSIST FAULT in the message center.
For DTC U3000:49, the presence of this DTC may or may not affect steering assist. It depends on what other DTCs (if any) are set along with U3000:49. Diagnose all other DTCs before diagnosing U3000:49. The module also sends a message to the instrument cluster to display POWER STEERING ASSIST FAULT in the message center.
