Looks like from that image that the trailer brake module is housed under the bed, and the control in the dash is just a control. The towing package just comes pre-wired for an aftermarket brake controller. I seriously doubt they would include the brake module and not include the interface in the dash.

Gentlemen,

I just crawled under my 2016 SLT and snapped this photo...

Is this the brake controller module mounted right above the spare tire? It could be. However, I could not find any information on part number 23231860. Perhaps some other super sleuths might be able to help out here.

Since the OEM controller uses the DIC to display information I would assume if one were able to procure just the switch that there would be some programming that has to be done to the computer(s).

I believe that is the Chassis Control Module. If you download the Upfitter Electrical Schematics, they show the CCM located above the spare. (Do a search on "spare" on the upfitter manual, after a few references to spare tire itself, you will find this module located. )

I should give credit here to SavageBob, he posted something about this module a few weeks/months back.

So confused. I was under impression if we have trailer wiring already installed, we could get the brake controller and some sort of trim package for dash change, and we would be in business.

Would be great if anyone has done this. Anyone? Anyone? Bueller?

i would assume the same thing. If we have the trailer brake control harness installed, i would think the module would also be there . I hope that is the case.

I also found some more infomation. Under the fusebox in the hood you want to look for fuse F27 which is the Trailer Brake Control Module.

Circled in blue is the 30A fuse for F27 - Trailer Brake Control Module.

Im going to assume that because a fuse is populated in that position, my truck has the module already installed.

Here's he best pic I can get without dropping the spare. Based on the diagram above, the finned aluminum module is the chassis control. My Duramax doesn't have anything where the trailer brake controller module is shown. My guess is that it is the module shown in my pic. Just a guess...

 

[DasGoob]

So what will it take to actually get the entire system to work? I am assuming that the dash unit will not allow the entire system to be activated. Good assumption?

Well for those looking here is the part number for the trim piece for the Brake Controller.

This one is black with that leather like texture.

Now, how did you sleuth out that part number and how can I figure it out for Cocoa Dune on a GMC Canyon?

I think I found it... 23299084. Started typing in part numbers incrementing by 1 until Cocoa Dune came up.

Gentlemen,

I spent some "quality" time with the gm upfitter electrical guide for the 2016 Colorado/Canyon. Man, what a great resource. I have come to the following conclusions...

1. That module I posted a picture of is the Chassis Control Module ( K38 ). On an LFX equipped truck it controls such functions as the aero shutters and fuel system.

2. The Diesel has a completely different Chassis Control Module( K38 ). On an LWN equipped truck it controls the trailer brakes. It is the brains that interfaces with the switch in the dash and then notifies the Trailer Brake Power Control Module (K133) which appears to be what actually passes the brake signal to the trailer.

It's obvious from the pin outs of the two Chassis Control Modules they are not compatible. You can't use a K38 from a diesel on a gasser and vice versa. They don't even use the same connector. Since this module is the brains I find it very unlikely we will be able to get JL1 (oem brake controller) on our trucks. In order for us to get an OEM brake controller we would need completely different Chassis Control Module, the Power Control Module and dash switch. That's assuming GM has the foresight to prewire the existing harness for the additional pin outs for the controller. Anything is possible but I find it highly unlikely. We are in the same boat as the Sierra and Silverado guys are. There is no way for them to add JL1 to a truck that wasn't equipped with it from the factory.

Now, this is just me doing a little reading up in this upfitter guide but I would expect if there was an alternate K38 it would have been listed in the guide.

Bummer for us V6 guys.

I guess there is hope for an aftermarket solution that fits in the dash, we might not get the integration with the DIC, but 4 wires is 4 wires regardless.

 

[Padre]

Good information. Thanks for the research.

I thank you for your research and insight on this topic. I'm still hoping GM makes this functional for those who'd want it on the 6's like me.

Just to follow up on the great post by Curtiss above:
If you want to find more than you ever wanted to know about the brake controller in the Duramax, check out the 2016 Upfitter Guide Electrical manual. It's a mind-blowing 913 pages, but you can find what you want on pages 62-64.

I am losing hope for a OEM controller so my next go to is to get the dash plate and switch then solder the buttons into an aftermarket brake controller. Then I can hide the controller in the dash. May need an Arduino to make some of the buttons work. I really just do not want a brake controller at my knees. This "modular" brake controller here (Hopkins 47297 INSIGHT Brake Control) would be a good start. Seems like it would be easy to modify and not not have to void any warranties. May just have to order the part next week and see what I find out. If anyone has any ideas let me know.


I will update this if I get more info.

Dash plate: 23299082
Switch: 23145874
Switch plug: ???
Brake controller: Hopkins 47297

I believe all the switches on the these trucks are actually microcontrolled modules. I don't believe you will be able to interface it with a third party brake controller.

I've actually ordered the parts to put something together that I think will look quite nice in the stock location. The parts are on order and I'm hoping to have them late next week so I can work on it over the weekend. I'll post pics when I'm done.

It's centered around the Redarc Tow Pro Elite brake controller. You might want to google it and check out the youtube videos. It may spark an idea like what I'm doing for it in the oem location.

Yeah you are probably right about the buttons but maybe I can convert the buttons "signals" with an Arduino. That Redarc actually looks really nice, for the price it seems really reasonable for one that is active instead of just a timer.

 

[CaryBosse]

I really just do not want a brake controller at my knees. ...

This is the main reason I have yet to choose a permanent location for my controller and why I am following all of the various brake controller threads.

May sound crazy, I love my V6 truck, but there is a part of me that is longing for the diesel, and half the reason is simply the integration of certain things, like this brake controller. I know that is not in the books until 2019/2020, barring a lottery win or some catastrophe, but I still can dream.

This is the one I purchased after it was verified we cannot use the oem brake controller

I mounted my display where he put his but I will be mounting my controller (slider) to where he has his 4WD knob because I only have 2wd. The brain will go down near the kick panel.

Wiring goes as follows from what I researched:
Red/Green Wire from Truck (Battery Feed) -> Black Wire on Hopkins
Black Wire from Truck (Ground) -> White Wire on Hopkins
White/Blue Wire from Truck (Brake signal to Controller) -> Red Wire on Hopkins
Blue Wire from Truck (Trailer brake power to trailer Brakes) -> Blue Wire on Hopkins

Thanks for the info. That actually looks really nice install, as far as a non-oem install goes. If I do get this altogether I will make a guide on how to do it.

Just looking at the engine fuse box to check a fuse and noticed we do have a fuse in the 2015 for a brake control module fuse # F27. Why would that be if we are using a totally isolated Aftermarket brake controller or at least I thought we where
