Hey guys, I've got a buddy of mine coming home from Wyoming in a very bad snow storm and his built in trailer brakes have multiple failure readings. He has a 2012 dodge 3500 6.7l dually.

First error msg says heavy electronic trailer brakes disconnected. Second message shows a trailer with a line through it. 3rd message shows a yellow flashing trailer with a message in it that says CF. He has pulled the fuse and checked it and to posibly reset the brakes. No luck. He had a double blow out and the problem started afterwards. Any ideas to help me get some info to him. He is navigating through the mountains in Montana.
