Hey guys I got something going on with my trucks Trailer brake controller. My truck is a 2008 F-250 Lariat. Every time I start it it immediately displays a “trailer brake controller fault”. If I hit the reset button it goes away. The controller seems to be working perfectly normal as far as functional lights, etc. I have put a 7 way plug tester on the trailer plug and all the appropriate lights,( brakes, turn, 12 volt charging, etc are working. If I use the manual controller sliders I get braking power at the plug. Problem is that if I set the gain all the way to 10 and press the brakes no braking signal/power at all. Anyone have any ideas,? Also, on the chance the factory plug had corrosion I replaced it with a new one before the test. I’d appreciate any ideas. Thanks.
