Ive had the TC and ABS lights on since i got the truck last year, I have already checked to make sure the wheel sensors are seated. My question is, can I diagnose this myself without paying 100 bucks to have it scanned? I know that my ABS is not working as when under hard breaking it just locks up no ABS studder. Does this also disable the traction control as it works by braking the wheel without traction? Your input is appreciated.
