All 2017 F-Super Duty vehicles equipped with a factory trailer brake controller (TBC) utilize a trailer
module (TRM) which initiates the trailer charging system. For trailer charging to operate, the TRM
must detect a trailer is connected and a brake pedal input before charging will be present at the
trailer connector. Adding the trailer battery charge relay and fuse into the battery junction box are not
required to operate trailer charging with a TRM. If testing of the trailer charging system is required
without a trailer, refer to the updated diagnostics and system operation found in the online Workshop
Manual (WSM), Section 417-01 Exterior Lighting.
