Summary

Some 2023-2025 F-Super Duty vehicles equipped with a trailer brake control module may exhibit a "Trailer Disconnected" message after cycling the ignition off and back on with a trailer connected. This may be due to the presence of an integrated battery charger on a trailer equipped with electric over hydraulic brakes. If trailer functionality is restored after unplugging and plugging the trailer connector back in while the ignition is on, this condition can be corrected by downloading and performing the "Trailer Brake Configuration" application using the latest version of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 19H332 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

Owners of these vehicles have filed 29 complaints in the brakes category.
