2006 Ford F-350 Integrated Brake Controller Troubleshooting: No Trailer Connect Message

Question

Question:

Good afternoon, We have a 2006 Ford F-350 we use to pull our gooseneck flatbed. All the running lights, brake lights, and taillights work correctly, but I have no trailer brakes at all. The stock brake controller indicates no trailer is connected and throws a fault when I use the slide to test the brakes. In your experience what do you believe may be the issue causing this?

What you described sounds like a short on the brake output circuit. What you will need to do is go over the trailer's brake output circuit looking for anything obvious that would cause a short like exposed wire or corrosion and fix as necessary.

I also attached a help article on brake controller troubleshooting for you to check out as well.

Basically I was referring to the width of the goosneck trailer nose. So measure the width of the trailer at the very front. This is the formula you referenced though. To determine if you can safely make tight turns, there is a formula you can follow.…

I would start by using a circuit tester, item #PTW2993 if needed, to check the wiring going to and coming from the brake controller. There are 4 wires that will need to be checked. White - Ground Red - Stoplight Switch Black - 12 Volt Constant Power…

If the controller is working fine with one trailer and not with the other then the problem is most likely with the trailer and not the truck. I would start by checking all of the ground connections on the trailer, especially the ground at the coupler…

If your current springs have 5 leaves then going to a 7 leaf spring will increase the height of the trailer a little and make the trailer more susceptible to sway. Regarding capacity if you go with springs rated higher than what is required it will…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
