ABS Module DTC C0051 Steering Angle Concerns With The PSCM

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2019 Ford Expedition, 2018 Lincoln MKZ, 2018 Ford Transit-350 HD, 2018 Ford Transit-350, and 2018 Ford Transit-250. However, it is still accessible from the selected car via links, so may be relevant.

The ABS module and PSCM communicate and compare steering wheel angle information. The ABS module may have steering angle sensor DTCs present (C0051:xx or C006B:xx) or a stability control symptom and the ABS pinpoint test may direct the installation of a new EPAS steering gear.
Stability-traction control warning indicator illumination and traction control messages are normal under extra load conditions such as those experienced during towing, cross-winds, or gravel roads. There may also be some mechanical or electrical components which can contribute to the concern.
The items listed below can potentially cause the steering wheel angle comparison differences to be outside the expected range resulting in a C0051:xx or C006B:xx DTC to set in the ABS module, the stability-traction control warning indicator to illuminate and a traction control message to appear in the message center.
