Description On your vehicle 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, trailer stop lamps and turn signal indicators will not function. Additionally, for trailers equipped with electronic trailer brakes, the trailer brakes will not function. This loss of communication can occur with-or-without a trailer connected to the vehicle and can only initiate at vehicle start-up. If this occurs, a trailer brake module fault notification will pop-up on the vehicles instrument panel cluster. The vehicle brake and turn signal lamps will continue to operate normally and are not affected by this trm fault. If you do not tow with your vehicle, you may wait for ota deployment for your vehicle remedy. Safety Risk This may result in inoperable trailer brake lights, trailer turn signals and trailer braking functions that can reduce a drivers ability to control an attached trailer and make the trailer less visible to other drivers, increasing the risk of a crash. Remedy Software is available to repair your vehicle. Ford Motor Company has authorized your dealer to reprogram your vehicles trm free of charge.
