The harness from the brake controller module to the trailer wiring plug needs a diode, the Mopar harness does not have the diode which results in the dash errors and safety systems being disabled until the next key cycle. The issue is not happening on all vehicles. I am trying to figure out if there is a pattern between options and build dates.
Perfect, when I get my Jeep back tomorrow, I will try it and give you the info you need.
It works like most other controllers, drive slowly and turn the gain up, apply the brakes, if you feel drag without locking the trailer then it is good. The only time the manual button is needed is if you are trying to reduce trailer sway at speed or going down a steep high speed grade.
Dealership overbooked and I picked it up with the job partially done. I have a new appointment on November 23rd. I have provided the Service Manager with the details on problems with the controller and my experience with the service. He is interested in seeing if the controller will work or not and why. His bulletins that he read are unclear. I will post results on November 24th.
If your Wrangler came with the trailer tow and auxiliary switch group (ADH) and they tell you that you need the harness referenced in the directions or that your Jeep needs programming they are wrong. The additional harness is not needed and there is no programming needed.
I do have the auxilary and ADH, however the bulletins from Chrysler where a bit unclear. So the Manager is going to see if it works on my Jeep and the differences. Nothing like explaining to a customer that they can't get an item to work. This will also be good to know for future purchases and orders. What ever they want to do with the information is up to them.
What if your foot is on the brake?
I agree, bought this Jeep to tow travel trailer. Pretty agitated right now...
