Service bulletin SSM 50217

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.

NHTSA's summary

Some 2021 F-150 vehicles may exhibit diagnostic trouble code (DTC) U0143:87 stored in the trailer module (TRM). This may be due to various software parameters in the TRM. This DTC should be disregarded as it does not cause any observable concerns or warning messages and does not affect vehicle performance or durability. Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) TRM update beginning in March 2022 to prevent this DTC from setting.
