Mopar Trailer Brake Controller for Jeep Gladiator Officially Released (Part # 82215652AB)

[shrinkhead]

Wrong. Maybe you didn't read the original posts in these threads where we talk about it happening WITH trailer or without trailer.

It occurs any time you want to apply trailer brakes only or setting and/or are testing the braking force of the trailer brakes. (such as initial setup, or adjusting gain)
It happens WITH trailer connected
It happens with NO trailer connected
It happens when you are not applying the truck brakes

If you were running down the road, ran into some sway, or for whatever reason, wanted or needed to apply the trailer brakes, but not brake the truck (as to come out of sway or an emergency situation) it would happen.
If you were adjusting the gain of the trailer brakes - the braking effort applied to the trailer only, and you pushed the button to check trailer braking (like I do EVERY TIME as perhaps the trailer is heavier or lighter than last time, I ALWAYS reset gain if there's been some time since last tow or my load is different) when you push that button it will happen.

It is a fault, not normal.

I know you are very passionate about this topic and thank you for that. I have to ask again though if it also happens when you apply the truck brakes or only if you don't. That piece is not clear to me and basically will decide if I install this or not on my 2019

Only if you are not applying the truck brakes.
The reason is that when applying the truck brakes, the BCM is aware of the pedal being pressed and thus is expecting a signal on the brake lamp line.
When the controller button is pressed to apply trailer brakes - adjusting and testing gain, or trying to come out of a sway, or to maneuver a trailer by braking only the trailer, and the truck brake pedal is not pressed, the controller puts voltage on the brake lamp line and the truck is not expecting anything and it sets codes - ABS faults among other things. Because it thinks there is an issue with the ABS, it disables front collision avoidance and ACC among other things, likely the ABS would also not function properly - maybe even traction control. You lose some of the braking features until you shut down and restart.

If you try to set gain like you are supposed to and check it by applying trailer brakes, you'll set codes and cause errors. If you tow and need to apply trailer brakes only in an emergency situation, trying to come out of sway, whatever, it will give errors and set codes.
Perhaps no one follows protocol and sets and checks trailer brake gain each time they tow or have a different weight on/in the trailer, or if it's been a while, recheck things, and from some of the posts, it appears a few people don't even bother to test trailer brakes only...... but I do.
I've seen the results of idiots towing and not having things setup properly (elderly couple decapitated in thier car, for example)

I would NOT install this in a 2019 build without adding a diode to the brake lamp line in the harness or using the Tekonsha wiring harness.
I am leaving mine installed - FOR NOW - in hopes for a fix from Jeep - otherwise I will NOT TOW with this controller. I just won't. My luck I'd need to hit the trailer brakes or need to set/change gain (maybe load a car or unload a car and pull the trailer).

JT owners are free to do as they see fit - but it's not a good thing if you must use that button and it disables the trucks safety features and throws braking for a loop.

Yeah, I have a passion about some safety things related to brakes and towing. There are things I simply can't unsee, even after 40 years.

Is this the correct harness?

You want the 3073P, not the 3024.

I'd look around as I found etrailer to be more expensive than some other places. In fact, I got my Redarc stuff cheaper direct from Redarc.

In this case, O'Reilly has it a lot cheaper-

Or try amazon - IF this is the same one, it's HALF PRICE =

I have bought several things a whole lot cheaper than etrailer just by doing a search for the brand and part number. They are expensive, IMO.

Make sure you get the one for RAM trucks - even the Redarc harness I used was for Ram.

Yeah thanks. It also looks like there is a JEEP specific one with the number 3073-P which I have now ordered and from what I understand no need to flip the wires on that one. I'll report back.

I don't think the JEEP one has the diode - Others' can confirm or say I'm wrong, but if it doesn't have the diode, it will be just like the Mopar harness....

In that case I'll just order both so I can flip the wires on the RAM one

Just compare the original Mopar controller JT harness to the Ram harness.

I thought the wire flipping was a Redarc only thing.......... but maybe Tekonsha has that thing, too.

Based on some of the reviews online for this one that is what people have been doing on JLs and JTs to get rid of the errors. Obviously not very robust Intel but worth a try while I have it apart when doing the install to just test the different configurations and harnesses

I’m a little confused. I thought the 3073-P is the one that will work with the mopar controller without issue. I bought one from amazon but haven’t yet installed. Do I need to get the 3024 or is this the right one for plug and play without dash lights?

 

[jwilson2899]

3073-P is the correct Jeep harness, and requires no wire swap. It also has the diode as well. That’s the one you want.

3073-P is the correct Jeep harness, and requires no wire swap. It also has the diode as well. That’s the one you want.

And since this controller is apparently a Tekonsha controller made for Mopar and Mopar branded, it is even MORE WEIRD that Tekonsha has for months had a harness with a diode that is wired for JT but the thing supplied with the Mopar version has no diode.......... and well, all of this makes zero sense.
Especially when we consider the 2020 build date JTs don't have this issue, the 2019 built date JTs do, Tekonsha apparently made the controller - and their harness has a diode, the one in the Mopar box does not...........
I'm still holding out for a Mopar/Jeep fix as if it's a BCM-based fix, that's what I really want, not a band-aid, but until mother Mopar comes clean and out with a fix, here we are.
Spend more money to make a product work that should out of the box.
Winter is here with a slap in the face and about 6" of wet snow so no towing anyway for a while now.

Installed the mopar brake controller
Dash lights up like Christmas
Found this thread
Im pre-January 2020 build

figured this pic should be in hereand ill see my dealer next week

mac ‘could be discussed somewhere else also and i missed it’ gyvr

LOL - yeah, I bet I posted the TSB and associated document at least a dozen times here and in other threads.

If I had the "power", I'd post them, make it a sticky and lock it so they'd not get lost in 150 pages, but I don't have that power, so I won't

The TSBs I have do NOT make mention of "automatic only". Not sure why there'd be any difference, the controllers work exactly the same in ALL trucks but MAYBE Jeep used different ABS code in the manual transmission vehicles. Anyway, I have not seen that on any OFFICIAL document to this point.
Bottom line - if you use any brake controller in your JT and your JT was built before 1-8-2020 AND if you have codes set and the dash warns you of disabled stuff, get the TSB done. It's really that simple!

Install trailer brake controller.
If it does NOT cause errors when you push the controller button and do NOT have your foot on the brake pedal, you are done.
Else If you press that button with your foot NOT on the brake pedal and it causes issues on the dash with errors
Then get the TSB done.

There, that was simple!

There's a notice telling dealers to IGNORE the instructions, ignore the bit about the harness, then there's the bulletin itself. Maybe no one clicks on it?
