Manufacturer summary

Original wording in English

Some 2023 F-150 vehicles equipped with a 3.5L PowerBoost engine may exhibit a Trailer Brake System Fault See Manual message in the instrument panel cluster (IPC) and/or diagnostic trouble codes (DTCs) U0140:87, U0143:87, and/or U0444:82 stored in the trailer module (TRM). These symptoms can occur without a trailer connected to the vehicle. This may be due to the software level of the gateway module A (GWM).

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.
