This is my first Chevy and got an 8 inch lift and 37 inch tires the first time I put it in four-wheel-drive to drive home from work the next day I got up and it said service four-wheel-drive system. What does that mean?
My Autel scanner also does the same thing. Not fully clearing fault codes using the "clear all codes" function. Yes, it only takes a few more seconds but it's annoying as hell. They need to fix that glitch! Anyways, Good find and repair.
Thanks for the comment. I don't think it's the scan tool at fault. I've noticed even using OEM scanners the same issues. Also on some ABS systems you can clear codes but they don't actually clear until the system performs a self test which might require a key cycle or wheel speed input.
