brake problem
I have a 2006 f350 with a factory brake controller. I have been getting trailer fault messages when I hit the brakes. With it hooked to the truck I get brakes when just manually using the controller. But when pressing the brake pedal I get no trailer brakes. The local ford dealer tested it and said there was nothing wrong with the truck. I hooked another truck to the trailer and the brakes work fine. Any ideas. Thanks
