Latest recall 2024 GMC/Chevy towing trailers with solar power

[TPC]

Taking the Dually in for an update and a module replacement today.
Evidently trailers with solar and some other conditions back-feed power to the truck triggering a check brake system light and may disable braking.
Wife says she's sure it did it once.
Then an update of some sort.

I had that issue with my old Chevy. Could never figure it out.

We’re in Vegas and it failed again.

I’m pretty sure this issue has plagued GM trucks for a long time

Were told turn off the solar in route it’s sending a confusing signal to the truck.
Figuring that out now.

Hmmm. I have an older GMC (2004), and my trailer has solar. I haven't had any issues. Maybe my truck is too old for the back feed to affect it.

Just finished both updates as well about 2 weeks ago.
So far no issues and i have towed short distance 2 times and so far so good.

It used to do it almost immediately after putting it in drive and would do it a few times but then would be fine for my whole drive after. Funny it never did it the first 6 months of owning the truck and towing about every other weekend. Trailer has 400watts solar with lith batteries..

Hope the issue has been taking care of just a touch annoying haha
