Activate trailer brake control
I bought a OEM trailer brake control for a 2025 F250 XL and try to program it through forscan activated in IPC trailer gain and trailer brake control and it still won't work. Does anybody have any recommendations on how to get it to work very much appreciate it.
So after many hours researching it I figured it out I had to go in to TRM (as built format) and change one number in 791-01-01 in second set of numbers i changed it from 0 to 1 and pressed write the at bottom of screen I pressed write all and followed the instructions and then it started working I also had to buy the one year license because I couldn't get it to work off free trial license
