@peterlawl84 Does your contact have an updated list of RPO codes? That Detect Off button appears to interact with the pillar airbags so I would want to ensure the the RPO code is clear before ordering.

I would pull that switch out and see if you can cross ref your part number in the list that's posted above. From there I would see what other part is the same but also includes the UV2 code in the Usage Column, along with the other codes that align to your original part. Keep us updated

It’s what you expect. It remembers your preference of keeping auto-stop on or off between engine starts. Install video is on the page as well. https://www.autostopeliminator.com/products/2021-2022-chevrolet-suburban-autostop-eliminator

Thank you for all your help on this! We have an 2wd Duramax Yukon SLT that does not have Hill Descent Control. I ended up ordering the part number 84786496, and I also paired it with the auto stop eliminator and everything works great.
