LED light bar causing all these issues.. Chevy

[geswek]

I bought a Putco 60” blade with quick connect harness. I keep having weird blind split indicator issues and Chevy says it’s the bar and it’s causing all these alerts.

 

Putco says it’s impossible.

 

Going to pick up the truck and pull the harness.

 

Has anyone had this issue before? Here are the install instructions for my bar: https://www.putco.com/product/blade-tailgate-light-bar-plug-n-play/9202060-05/

I have the exact same Putco Blade and harness on my 2023 1500 High Country.......works like a champ, zero issues.

Love this thing, so bright and looks awesome. 

 

It's easy to disconnect the harness going to the Blade to see if something is causing it.....

Yep. I had one on my 2015 and it never caused me issues. Now I got all these problems and they’re sending me on my way. Telling me it’s the light bar…..

 

My guess is they didn’t sell me the truck so they have no vested interest in helping.

There's another Putco blade thread on here somewhere in the past month or two. There was issues with where it was being powered

It's a GM Accessory.  It should have a 12 month/12,000 mile warranty through the dealership.

Thanks! I just found it on their website -- and it looks like it comes with the harness too.

 

I pulled the harness last night so will see if the issues go away.

 

If they do I'll contact Putco; maybe I got a bad harness that is back feeding power or something.

GM is hyper sensitive to modifications because of warranty costs. There are a lot of instances where trucks have been modded and the tech chased an issue that wasnt GM's fault. The new electrical architecture is very fussy.

If those issues go away after unplugging the bar, its the bar causing it. 

 

Did you get the bar from Putco or the one Putco sells from GM?  The one they sell through GM plugs into the tail light harnesses via an adapter harness, not the trailer plug like the Putco one does.

I got mine from Putco directly and it had a harness. I had to get under the truck and unplug 3 different plugs; and then plug in putco's harness, then the GM plugs back into it. And at the end was a 4 pin plug and reverse plug -- along with a black box.

Gotcha so its likely the trailer style ones.  The harness had 2 round plugs and then the 4 flat?  Also, black box?  Did you buy the Freedom bar or the standard bar?  The Freedom bar, someone on the forums here has had nothing but problems with on a 2023 I think it was?

I don't think so. I think the trailer functions are based on detecting something plugged into the trailer plugs -- tapping the feeds for the lights themselves I would think is OK. Maybe. Just what logic is telling me but I could be so wrong.
