Does anyone know what fuse may operate the lane assist in a 2021 Suburban, i can't figure it out by looking a fuse diagram

lane assist is a function of ..........

The lane keep assist system is made up of the following components:

B174W Front View Camera - Windshield
P16 Instrument Panel Cluster Control Module
Multi-axis acceleration sensor (part of the K36 Restraints Control Module)
Steering wheel angle sensor (part of the K43 Power Steering Control Module)
K43 Power Steering Control Module
Lane keep assist switch
Infotainment system
Safety alert seat (with HS1)

So, no single fuse.

Do you know if the front camera B174W camera is VIN locked? I have been told this and it doesn't make sense to me.

Keith. Curious why you're looking for the fuse. Is lane assist not working? I don't know the Suburban is the same or similar, but my 2021 High Country Silverado had the lane assist button on the dash that wouldn't light up at all and also intellibeam, which I don't use, didn't work, and more importantly my cruise control stopped working. It turned out to be a code thrown in the BCM, dealer cleared the code and all working again. I posted here somewhere. If I can find it, I'll edit this. But it wouldn't come on because of the code if that's what you were checking for. If you want to disable it or something, sorry.

I don't know but would be surprised if it were.

I've played with the BCM plenty to know there are 4 or 5 fuses for the BCM all are labeled but not specifics in the two drivers and passenger side fuse box I doubt there's a fuse specifically for lane keep or the intellibeam. However, windshield camera fuse? maybe? headliner harness powers the overhead console... headliner fuse? good luck again still not sure what you're trying to accomplish.
