So I just picked up my new 2019 gmc evolution which I love, traded in my Doge ram and ill never look back.  Since this truck was one on the dealer lot it does not have the factory brake controller .  I know that you cant add it to the older ones but can the 19's be added.  Just hate to have to add an aftermarket one in a 2019 truck.  

 

thanks

It's possible to get the factory one installed. I got mine done on my 2019 Trail Boss. It was 300 bucks with the parts labor and software included at my dealer. The wiring is already there for LT

Guys and gals.  Its pretty cut and dry.   The Factory Integrated Trailer Brake Controller CAN'T.  BE.  ADDED.      

It's Tim
It's Tim

This is to advise you that, if the vehicle does not have the option (RPO JL1), it cannot be added to the vehicle.    They still won't get it.... 😉

Nope. The only option is an aftermarket controller.

 

Although, I suppose it would be *possible* if you are willing to tear apart half the truck, and replace several wiring harnesses and modules, and maybe the instrument cluster, and then hope that GM will give you the unlock codes for reprogramming. Which is another way of saying, nope, not possible.

Thanks for the good news.

The wiring is already there for LT and up Chevy Trucks. Just needed the controller and the software. 30 minute job at the shop.

This is interesting, and counter to just about everything I've read on here. So, it's only impossible on WT and Custom/Custom TB trucks?

LT trucks have all of the wiring already there for all of the features you find on an LTZ truck. The dealer can install it. They have to flash the computer to get the system to turn on once the hardware is installed. 

 

The WT and Custom trucks do not have the wiring already there.

Trailer brake control was an available factory option on all trim levels of the 2019 new style 1500. (and std on LTZ and HC).  

 

Perhaps it can be retrofitted to any trim of the new style.

It is possible, with all the trim levels.  Don't listen to those that say it cannot be done, they haven't even tried.

This bears investigation. Does anyone have a pic of the wiring harness and connector behind the dash that the controller plugs into? I can then verify whether or not my Custom has it.

I have a 2019 TB Custom.  The Brake Controller port is on the lower left driver side up under your dash.  You have to lay down on your back on the floorboard, look up to the left of the foot brake pedal and it's the GRAY Harness. I believe it does have a cap on it that has to be removed.  So you just need the controller unit that goes on the center dash area and the wiring that runs from it, to this location.  I'm not aware of what additional computer/ECM programming to enable the feature is needed, but the dealership should/can help with doing that as necessary. 

 

I read a post somewhere else, where a guy purchased an aftermarket Braker Controller unit and this GRAY port is where he hooked it up.  He did not mention any ECM/Programming required, the cost was something like $100+ and I think he purchased it from "etrailer.com"  Here is the website and instructions:  https://www.etrailer.com/question-354023.html

 

IMHO it doesn't look as nice as the factory unit, but it was certainly "doable" and not at all expensive.  If you were able to get factory wiring and the factory unit, it would be easy to pop into place on your center dash where it goes (lower left of the center console)

I figured this was the case as I doubt gm would allow a truck with the factory option to be able to add an aftermarket one as well.  I personally was going to buy the factory one and plugit into the port under the dash.  

 

Do you happen to know part numbers of what I need.  

Thanks.

^^ Ditto this. Also, what does the dealer need in order to program the unit? I ran across an issue with the Trailering Hookup Assist app where GM wouldn't provide the unlock code for the dealer to install it, because my truck didn't originally come with the option (which was the whole point of having the dealer install it!). I don't want to spend hundreds of $ just to hit a brick wall when it comes to programming.

Wow this is a complete change from the K2xx trucks as GM wouldnt allow the OEM trailer brake controller to be added after the fact.

      I can relate. 3 years ago I did that on my Avalanche. I was sore for a week. The only maintenance I do myself now is drop and fill on the transmission on my Honda’s. It’s just too easy. My yard work with my walks in the morning will be enough now I passed 70. The contributing factor is the heat in Texas. You just have to pace yourself.

      Forward collision and lane keep assist still a problem on 2022 refresh?

      By kr477 · Posted

      I am sorry if this was misleading. That was a document attached to our most recent work order number (Doc# 7105804) that summarized all the current updates. These programs were ‘redone’ in the past but these versions dated 4/1/2016 were the ones that actually made all of the problems disappear. These programs were relayed to the dealer from the technical services group at GM. Here is the exact wording on the last work order:   “Front view camera reprogramming with SPS. A new version of FCM software was released to the service dept. In addition to providing general robustness and stability enhancements, this update includes all enhancements from previous software version releases. SPS camera and calibrate camera. OLH to perform extended camera relearn procedure after camera calibration. Would not take with first GDS learn. Front camera SPS – BDYZ333157450 GDS2 – camera road calibration performed 2810835 Front view camera reprogramming with SPS LT 0.6 OLH – extended camera relearn procedure OLH LT 1.5”   I got the truck back on 4/8 – since that time it has been great no problems whatsoever. The lane keep assist, active cruise control and AEB all work very well around town and at highway speeds up to 80mph. During this time I had been away for a week and purposely let the battery sit without a batter tender. Even with the battery a bit lower there were no problems exhibited. I really think this one has it fixed after dealing with these issues over a couple of years. These new programs and relearn process when completed seem to make all the parts (and newer replacement parts) ‘talk’ to each other without any glitches. Hope this helps

      I turned 72 today. My day began with a trip to the pharmacy to pickup meds for me and the dog and then a stop at my chiropractor before heading home. Once home I started the job of replacing the rear brake pads and one rotor on our 2018 Silverado which will probably end up taking me 3 days to finish, gotta pace myself you know. Sometimes I question myself on why I still do most of my own repairs but if I wasn't then it's more than likely I would be sitting in front of the TV all day. It seems like the list of things I need to do gets longer no matter what I accomplish. I'm not complaining but being retired was so much easier when I was 62.   Peace

      google "bathub failure curve". Basically, any part of the vehicle can fail at any time.  It starts off as being more likely (early failure), then the failure rate goes down (but does not go to zero), then it goes up over time because it wears/ages out.
