For some reason I have all lights working truck an trailer. However no power is coming out of the truck for the trailer brake. Very puzzling as I have checked all the fuses relate to trailer. The factory controller is not giving any signal or warning of any sort. I even cranked it to 10. Still no output from the truck on the electric brake wire. Any thoughts? ideas?

Even thought the DIC is not showing an error code my $ is on an bad brake controller output. Because that's a variable voltage output depending on gain control setting and brake pedal pressure it's probably not monitored.

So i had a similar problem to yours. Everything worked but brakes. Some one mentioned turning off Cruise control when plugging in trailer cord. Something about the fuse being close/similar. I did that and everything has worked for 4 years now. And I can still use CC.
