Trailer Brake System Fault

[UpsideDownIn]

Cold start this morning, and out of nowhere I get this message. Didn't come back after restarting. Haven't touched anything related to the trailer system yet, so definitely strange and random. Anyone had this come up yet?

I haven’t seen it — but here are a few fuses to check:

1. Engine Bay Fuse Box — Check the “Trailer Brake Control Module Fuse” (30A) #42

2. Passenger Side Fuse Box - Check the “Trailer Brake Switch Fuse” (5A) #21

possible wiring issue.

There’s a recall/update on your rear sensor of the truck mines at the shop getting reprogram now.

Is it the trailer perimeter alarm? I’m not seeing anything else.

Interestingly enough, I just went in for that flash, and no problems afterwards until now. Haven't seen it again, so maybe a fluke.

How did you find out about the recall? Ford hasn't sent me anything.

I bought my truck 2 1/2 weeks ago and on the FordPass app on my phone, it showed Recall.

Interesting. I have had my truck almost 3 weeks and nothing on my fordpass.

This is what it it.

Wish there was more details on the nature of that Trailer Perimeter Alarm issue. Didn't get a good answer from dealer also.

 

[Dburns571]

The service manager said it had to do with a update to the system.

I picked it up yesterday works fine now.

Did it correct something specific you were experiencing? I just took mine in just because I got tired of seeing the recall on my FordPass app. LOL

 

[Dburns571]

My truck would beep in the rear for no reason at all.

After the update, it has fixed it.

This just started happening on my 21 tremor, any other details as to the issue?
