I used the gear/tire wizard after I installed 4.88 gears in my Silverado with 34.8 inch tires. Getting ABS/Brake light now. How can I fix it?

I am in the same boat exact tire and gears..i think we need to have a tech2 reprogram the BCM...i am going to try doing 4.1 and 29.4 into the wizard and see what it does..give me a few days to see what happens
check your speedo calibration I did a truck same thing happen under speedo>calibration>final drive
LSXSierra03, Final Drive are all listed at 4.88
Yeah I still don't have a fix...takes about 2-3miles then lights come on
This is the reason why I haven't messed with it yet. I keep seeing the same responses. One thing I was considering was not entering the tire size as listed but actually measuring the height and then verifying by using the chalk line method, that way it takes into consideration the tire pressure/wear/error. I know the size on the tire is never the actual size exactly, could this be the issue or no?
Any updates on this?
