2016 Crossroads Cruiser 322. 2016 Dodge Ram 3500
Last year I started having problems with the trailer brakes. Intermittently the truck system would chime and announce "Check Trailer Wiring". After a few times doing that, the system would announce "Trailer Brake Disconnected". This usually occurred when the brakes were applied, either through the brake pedal or the built in brake controller. After a while the controller would reset and we'd start all over again. Numerous trips to the RV Repair facility (No Crossroads dealers within a four hour drive) and the Dodge dealership, there was no diagnosis or fix. Finally, last week I went under the trailer and temporarily ran all new wire from the gooseneck J-box to the brakes. Guess what. I now have brakes.
Now, I now have the proper blue and white wires and will run a permanent system as soon as possible.
Yeah, I probably could have chased wires and maybe have found the problem. If you have never looked up into the belly of the trailer - don't. There are wires running everywhere and they are all loose.
So, my problem seems to be fixed, but I want to pass on my experience in the event someone else out there has a similar problem.
Best of luck and Happy Camping.
