# Service bulletin TSB 20\-2046

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## Other bulletins for the same vehicles and component

- [SSM 47701](/bulletins/10153943.md), 2019-03-04, Service bulletin: STEERING; SERVICE BRAKES, AIR:ANTILOCK. Some 2016\-2019 F\-150 vehicles may exhibit DTC C0051 in the ABS module. This DTC compares steering angle between the power steering control module \(PSCM\) and ABS and may set due to towing, driving in heavy winds, loose suspension or steering gear components, alignment, or harness or connector concerns with the ABS or PSCM circuits. The ABS pinpoint tests AE, LA, or LB may direct a replacement of the PSCM after disconnecting/reconnecting PSCM connectors. Do not replace the PSCM using ABS Pinpoint tests AE, LA, LB. Refer to the Workshop Manual \(WSM\) Section, 211\-02 to locate the correct PSCM pinpoint tests for the PSCM DTCs that are retrieved during the PSCM self\-test. The ABS pinpoint tests are in the process of being updated.
