wiring fault on trailer

2011 Fleetwood cougar, 2008 F250 Diesel. Been traveling very dirty, dusty and sometimes muddy roads in Canada/Alaska (Top of the Road highway for one.) Today, for the first time, a warning message came up - "wiring fault on trailer". It comes on for minute or so, then goes off for awhile. The output/gain module shows that I still have trailer brakes. Though every once in a while it goes red and out for a second or two - but I still have trailer brakes and lights. Any suggestions??

One suggestion was that the socket into the truck was dry and to try putting some Vaseline on the socket.

I'm in Valdez, AK and will not be near any repair facilities for more than a week. Nothing here in Valdez to assist.

DiElectric grease can be bought at most auto parts stores. It will help make contact and keep out moisture and dirt.

See if you can find an electronics supply house. With all the marine radios and bush aircraft up there you should find something.

Get a can of spray contact cleaner. Spray He== out of the plug and the socket.

On edit: any radio repair shop should have some you could "borrow".

Did that on my 08 Ford from day one. Went to no end of Ford dealers and trailer places looking for a fix. Eventually I replaced the Ford built in brake controller with an aftermarket and no problems after that. Good luck on your quest. I think my problem was related to the trailer hydraulic.electric brakes but if yours are just std trailer brakes, not sure what could be the cause.
