I'd try blowing out the plug with some compressed air. It's possible something got in there and disrupted the circuit. Could be a simple fix.

You have an unusual problem. I would think there is a loose connection or bulb socket in the trailer somewhere causing this message.

You will need to collect more info to find it. Does the message appear right after a bump or rough bridge?? Maybe it happens after aggressive braking??

Sounds like the circuit is being broken and then reconnecting itself, , , prolly on the trailer.

I can say from experience that a running light out will not do this. I had a side clearance light completely corrode away the terminals in the socket and the light was out but no message.

I think the brake circuit may be the place to look??

Good Luck with it

This has happened to me twice. All I did was unplug the trailer from the truck and plug it back in. That took care of the problem both times so, it does sound like a connection problem.

Don't forget, could be magnet wires in the hubs.

I made my Samsung SGH-I997 send this.

The problem did occur I noticed the second time after hitting a rough section of road.
I pulled my bumper pull trailer this evening and no problems so the problem must be in the plug in the bed or the trailer.It will be a few days before I have a chance to check it out.Thanks for the suggestions.

Its probably an old or dirty/corroded plug on the trailer. All my trailers would do this in extreme cold or wet slushy conditions. I would change the plugs on the trailers every time I get a new truck (2-3 years) and that would pretty much take care of the problem.

You losing a ground between you truck and trailer. I have had a couple of trailers do this because of my B&W hitch. What I have done is make sure that my trailer is grounded to its self. Now I don't have this problem.
