JUST brought a 2024 Silverado 3500 dually,  I have a HD trailer GVW of 26K. Electric over Hydraulic brakes. The truck dose not recognize the trailer for brakes.  I have 3 other trucks that it works fine with.  15 Silverado 3500, 21 gmc Denali 2500 HD , then hooked up to a 22 DODGE RAM 3500.  ALL TRUCKS the trailer worked fine.  GM says there is no Problem.  go figure.  Well their fix is to install a Aftermarket adapter non GM approved on my trailer to get them to work.  As everyone knows trailer wiring will not last and needs attended to because of corrosion and loose connections because of the environment.  So Spend 80k for a lawn statue.

I don't know if there is a question involved with your thread, but I have heard from other members on another forum, for Colorado's, about them having intermittent issues with the factory brake controller. So, on the 2017 Colorado I owned and on my "new to me" 2020 Custom I installed the RedArc system. The unit can be hidden and out of the way, while the dial is super small and not obvious.

UPDATE 7/15/2023:

Brake issue seems to be resolved.  I still need to clear the turn signal errors at startup every time. 

 

Additional issues now:

1. I have driven the truck/trailer a fair distance the past few days. New issue has arisen. 30 minutes into my drive the camera that is activated when the turn signal is applied does NOT show the side view of the trailer. It DID show it earlier in the trip but, now shows the FRONT camera view. After I stopped I took a video of the issue. Put in park and then revers, that cleared the issue.

 

2. The cameras for the trailer show a blank screen. I have the older camera that worked fine on my 2022. Blank screen.  I have a brand new camera that I plug in and same blank screen. I will have the dealership see if there is an issue caused when they did the bumper/bed plug swap. 

 

Sooooo, there is a service bulletin for the EOH brake systems NOT talking to the trucks correctly. This has been a known issue since about 2021. However, we found that this applies to our NON-EOH brake system (typicallly the Hydrastar brake system) on my Platinum horse trailer. Constantly dropping connection without losing lights. Constantly tripping turn signal failure alarm. 

 

We completed the fix by installing the Hydrastar Controller Adapter Module 382-7073 to THE TRUCK, not to the trailer, as this remedies the issue for any trailer I will pull. The bulletin says to connect it to the trailer. However, GM tech had our service department attach it to our truck.  So far it works fine after 50 miles. No turn signal or brake connection warnings at all. 

 

Our service department is filing this under warranty because it started immediately upon purchase. Even though this is not a GM part they use, it should be covered. 

 

Now, onto the camer system issues in a different thread!

 Did they splice the module into the wiring or just use an adapter and plug it into to bumper plug?  The module didn’t work for me splicing it into the trailer as I was told to do by GM

      Roll up bed cover experiences

      By XY74 · Posted

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
