always heard that these had to be "programmed " to the truck, i have a 2020 2500 that has no trailer lights, by far the worst truck ive ever purchased/ owned out of 90+ vehicles, never again ! thank you
Can confirm these do NOT need to be programmed. GM will state that if there are no lights it was likely caused by a fault in trailer wiring. When the unit fails, it’s “supposed to” kick the light on full so if you’re towing you aren’t driving blind at night.
Can you open your tailgate step with that trailer hitch receiver? I have the same one but cannot open my step without hitting it. Thanks for the video. I had the same problem with my 2021
I have a 2020 trailboss with the exact issue. You had said there was a recall for 2020 and my dealership says there wasn't and wants nearly 500.00 to fix it. Was there an acutal recall because I can't find one.
He couldn’t find it either. We had a friend with a 2024 and they covered it. Charlie chose to do it himself since it was a straightforward install and less hassle of having the dealer do it/fight them to do it. Maybe contact Corporate?
So I’m dealing with the same problem on my ‘21 right now but I just have no lights on my trailer. Ordered the part but was told it will need to be programmed to my truck. Did y’all have to do that?
I just bought a 2023 Sierra and the taillights on the trailer stay on all the time. I also get running light errors on the console in the truck. I'm assuming the same issue as yours.
You’re welcome! Also I found out in the meantime that since this is a new part number that it supersedes the old one as this one has revised hardware. So it shouldn’t happen again.

Asked Charlie to chime in on this. He said they make a special hitch for that style split tailgate so it doesn’t hit.

We don’t need to do any programming. And it’s worked flawlessly since doing it.
The trailer lighting module doesn’t show up in sps so no

Yea, exact same issue!
@@TheSometimesBuilds So did this module just go bad, and if I replace it, will this one go bad also?
@@TheSometimesBuilds Fixed it 100%. Thanks for the video

@@TheSometimesBuilds Awesome to know. Thanks again
First and first. Now let’s go to Mikey and Mel’s
What’s the part number
Trailer Lamp Control Module: 13554026 - $84.69 (at the time of this recording)
I think this is what my issue. At least I hope so
Did you have to get it reprogrammed
@@brandonehrke4549 nope just replaced the old with the new and it was good to go
That’s bull shit 💩
