Manufacturer summary

Original wording in English

Some 2021 F-150 vehicles may experience a diagnostics trouble code (DTC) U2100 in the trailer module (TRM) after installation of the Ford Accessory Trailer Brake Control kit. This may be due to an error in the configuration data needed to update the TRM. To correct the condition, follow the Service Procedure to configure and program the TRM and the instrument panel cluster (IPC).

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
