Automatic High Beams and Halo LED

[meloftis]

Good Evening, I have a 2024 2500 Cummins I purchased that came off of a lease. The automatic high beams don't seem to work even though its set correctly in Uconnect. Also, the halo LED on the driver's side head light will light up for one second when the truck is cranked, then goes off. I checked my fuses but can't seem to trace down the issue. Are there other things to try to troubleshoot or is there a wire diagram I can find?

Do you have your high beam stalk pushed forward? (Basically if you turn your headlights on with the rotary switch do the high beams come on?)

As for the failing signature light I’d take it to the dealer for warranty work.

The headlights are set to auto and the stalk is pushed forward setting them to bright. They don't dim to oncoming traffic. I'm going to call the dealer tomorrow and see what they say about both the auto dim and the LED.

My auto high beams have a mind of their own. Sometimes they work great, other times they refuse to turn off to oncoming traffic.

I'll say this though. They work 1000x better in my 2020 than they did in my 2017.
