WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2022 Lincoln Navigator, 2022 Lincoln Nautilus, 2022 Lincoln Corsair, 2022 Lincoln Aviator, and 2022 Ford Transit-350 HD. However, it is still accessible from the selected car via links, so may be relevant.

During the ignition cycle DTC U2016:47 initially sets, the PSCM enters limp home mode and steering assist is gradually reduced until the PSCM enters manual mode. The PSCM sends a message to the IPC to display POWER STEERING ASSIST FAULT in the message center.

During the next ignition cycle after DTC U2016:47 sets, if the concern is still present, the PSCM removes steering assist and enters manual mode. The module also transmits an invalid steering angle message over the HS-CAN and sends a message to the IPC to display the POWER STEERING ASSIST FAULT in the message center.

When DTC U2016:48 is set, the PSCM remains in normal operation mode, but all steering features: Active Nibble Control, Pull-Drift Compensation, Evasive Steering Assist (ESA), Lane Departure Warning (LDW), Lane Keep Assist (LKA) and Lane Centering Assist (LCA) may be disabled.
