Official summary
Some 2021-2022 F-150 vehicles may still have a false alarm activation with a trailer connected and/or diagnostic trouble code (DTC) U0143:87 stored in the TRM after technical service bulletin (TSB) 22-2122 was completed. This was due to a software release issue. To correct the condition download and run the TRM configuration application in the Ford Diagnosis and Repair System (FDRS). For claiming use 12651D4 in section 10 of the service labor time standard (SLTS) manual.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
