I think he covered it already but that’s probably the problem. Gotta set it to the LM2 . It just takes a little time to get familiar with it and find the settings. Should work fine for you then.
What did you do to your AT4 today?
- Thread starter LamboTexas
- Start date
I updated the firmware and I selected LM2 for the vehicle. It shows when I start it up but then a few of the displays show blank when I drive. It was mentioned a comm setting but I haven’t found that. I do still have a bad NOx sensor that I am waiting on the dealership to get the part in.

I bought mine from Shop Chevy Parts.com Shipping is a little expensive but they're cheaper than anywhere else I could find. I didn't actually put them on yet. Waiting until I get it ceramic coated.

Might be a Banks question...mine works like a charm.
Have you had any issues with your auto high beams after install?
They basically said wait for a software update. I have used two different versions of firmware so either a bad cable or bad iDash.

None at all. They function just like OEM. Still have to manually activate the foglights when the low beams are on. But whenever the high beams are activated, either manually or automatically, the foglights come on, too.

Made it 2,500 miles before the factory Goodyears had to go. I can't believe GM puts the Territory on the truck from the factory, some of the worst tires I've ever had. Replaced with 275/60R20 Toyo Open Country RT Trail. Only drove it home from the tire shop so far so I need to put more miles on them before I form an opinion. Had read great things about these tires though.

Great choice. I had the Nitto Trail Grapplers on my last truck, which are similar
I am trying to decide between those 2 for my '24
Keep us posted on the road mannerisms!

I like my RT Trails. Went 275/70-18’s. They were a tad lighter than Ridge Grapplers and seem to ride well. They have a little noise but it is a truck. I can live with them.
Toyos don’t last anywhere near as long as nittos I have found out. But that’s on 3/4 tons. Especially towing the nittos far out perform anything I have found for longevity.
