Invisible Trailer error

[MN1965]

I picked up my 2024 Yukon Denali with the trailering technology package. I'm trying to set up my invisible camera and have a persistent error that I can't clear. I'm doing the calibration drive at the recommended speed on a good road with no curves. I've tried unplugging everything, engine shut down, etc. Any ideas?

You're one of the few Yukon owners that has that feature. It's basically been on 100% constraint for the last three years so I don't think there's many people on this forum that have it and can share their experiences with the setup.

Not sure if you've looked at this guide, but maybe it has something in it that will help you?
