I have had this issue with customers purchasing a new trailer with the built in brake controller on all new trucks. First off go to the dealership and make sure you have the newest update and that your brake controller is unlocked. If your hooking up with a 7-pin connector you should have brakes, lights, brake/turn lights and also be able to adjust the brake controller setings from the dash.
Having a problem with my new 2014 dodge ram
. When I hook up the trailer, I get a"trailer not connected message on dash board but everything works on the trailer, lights brake turnsignals I went through the settings to set up the towing instructions. Any help or suggestions would be greatly appreciated.
