Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
CSR-3308
Service Bulletin/Repair Instructions
Altec Industries, Inc. has received notification from Ford Motor Company that a condition relating to motor vehicle safety exists in certain 2022-2026 Super Duty vehicles equipped with Altec equipment. It is possible that the trailer module (TRM) may lose communication at vehicle start-up. If a TRM loss of communication occurs and a trailer is connected to the vehicle, the trailer's stop lamps and turn signal indicators will not function. This may result in inoperable trailer brake lights, turn signals, and braking functions, reducing a driver’s ability to control an attached trailer and making it less visible to other drivers, increasing the risk of a crash.
