Gear/Tire Wizard

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

I replaced my EBCM and had the dealer program it. Same problem.

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?
