I've got an intermittent Trailer Wiring Error message that started appearing with a trailer connected on my '11 F250.

Brakes and lights work OK on the trailer, I thought I had read on the board here that there was a TSB for this, but I cannot find it.

Does anyone have the TSB ## handy?

Thanks, Ben

 

Here is a list of the 2011 F-250 TSBs

No trailer wiring fault listed, but you can certainly search it for yourself.

Great, thanks!

 

I had the same error many times with my newer trailer. To diagnose it one night I was on a side road when it happened with no traffic so I just stopped and it was while I was turning right.

I got out and wiggled the connector while the wife told me that it then said that it was connected again.

The problem I found is when it is cold outside this cord doesn’t seem to be the same quality as my older trailer connector and it gets much stiffer than the older cord.

When turning right the cord would be stiff enough that it would lift the door on the truck side of the connector and the trailer brakes would come disconnected as that connection is on the bottom side of the plug.

Even though the cord still had play in it I ended up re-routing the cord around the left side of my front jack and it does hang a bit lower now while driving straight, I don’t get the error anymore of it coming disconnected.

 

There is defintely a TSB for this issue even though I couldn't find it in the TSB lookup.

I had it done on my truck. Dealer replaced the module and said it was a known issue. I will see if I can find the paperwork.

 

Please let me know if you can find it!

 

The dealer won't look it up for you? I told my dealer what was happening and they looked it up and ordered the part.

I got the Trailer Disconnected message maybe once every month or two when I started the truck up. Then it started happening almost weekly.

 

Sorry, I thought you had it handy on your paperwork, just having the TSB handy when I show up at the dealership makes it clearer with less room for confusion, no big deal

 

I will try to find it and let you know.

 

Just checked, the only thing besides text on the service summary is SSM 22884, hope that helps.

 

THANK YOU!

 

Do yo know what module they replaced?
