Subscribed, would love to know this as well.

 

This thread has a lot of discussion on this topic. See my post (#11) for what my dealer told me.

I did see your thread a while back, I was looking for it so I can post it there but could not find using the search. I just don't trust dealers until I see it for myself. Sometimes they say "mods/changes" will not work because they go by exactly what GM tells them. Even if it works they will never endorse it or tell you it will work until GM tells them, I think because of lawsuits or something.

PS 08Canyon, you can merge this thread with the trailer brake controller thread.

 

OEM controller

I believe the number you are looking for is ACDelco 23145874


You can also take a look here at http://www.jegs.com/i/ACDelco/065/23145874/10002/-1 to see a pic and vehicle applications

That part looks different or missing the top levers. Here is the picture of a diesel Colorado.

 

Any idea on what the part number would be for the trim piece that goes on top?

 

After looking around it appears to be number 14- not sure if the part number is different or not. Not easy to look at parts diagrams on a phone...

 

What is that website? I would like to look at stuff on there since I am interested in a factory brake controller as well.

Nevermind I found the site. It is gmwholesaleparts.com if anyone is interested.

 

Subscribed...I too would be interested in this.

 

I thought that I may as well look and see how to put an OEM controller in a Silverado as I figured they would pretty much be the same. For Silverados if you do not have the RPO code JL1 you can't do it. There was also mention of needing to mess with the computer. As of right now I have given up on an OEM install in mine unless a harness comes out sometime that does it. I won't have it screwed in though. I will just have it velcro'd so I don't damage anything, and so that if a harness does come out I don't have holes in my truck.

 

Any updates on this or anyone know where I can try to look up 2016 parts. Most online part sites only show 2015. Looking for the trim piece that goes on top of the trailer brake controller.

 

This seems to be the trim part that covers the controller:

Has anyone installed the OEM Factory Brake Controller

Following up to see if anyone has actually made this install in a non-diesel 2016 Colorado?
Has anyone installed the OEM Factory Brake Controller (that is available in the new 2016 diesel Duramax) into a non-diesel[A1] Colorado? Replacing the toll cardholder with the OEM brake controller (Amazon.com: ACDelco 23145874 GM Original Equipment Trailer Brake Control Switch Assembly: Automotive) and appropriate trim? I know there are many after market brake controllers, but the OEM one would be a much cleaner install and look.
I am looking for experiences/install tips/pix, etc. The controller is available but what about the trim piece and any associated wiring harness?

That is just the interface to the factory chassis control module, and is not a self contained controller.

Thanks to @NorcalAP2 parts diagram, we can see that a brake controller module is needed in addition to the existing chassis control module.

 

I had forgotten where i got this site from... i have it open at my home computer and will update the site when i get home.
For now...

Looks like as long as we have the wiring #2 then we can purchase everything else... Im not saying itll work for sure, just saying it looks like it can.

 

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?

 

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.

 

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...

 

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.

23299082

 

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.

Good information. Thanks for the research.

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.

 

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.

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

 

Fuse #F27 does indeed control power through the trailer brake controller wiring harness located behind the driver's side kick panel. I know this because I shorted mine out when wiring an aftermarket trailer brake controller and had to replace it.

 

Just seen it was found on previous page, on my chassis builders wire diagram on page 243 it has a item listed as electronic brake control module K17

I think we need to be very careful with the nomenclature here. The BRAKE control module you describe is indeed found on the left frame rail, by the rear of the transmission. This module has hydraulic brake lines running from it so it must be to control the ABS system. The TRAILER brake control module is located just above the spare tire, with the chassis control module. I just verified this by sliding my aging body on a cold garage floor. The sacrifices I make for this forum...

 

Diagram says its located ""On vehicle underbody, near the rear of the transmission, on the left frame rail "

 

I was just looking at the diagram and wires from it. It is for ABS as it is connected to wheel speed sensors and such. There is wiring for a module but there are probably all sorts of programming to be done to make it work like posted before.
