My ABS light and brake light both come on when I get on the brakes pretty hard, and stays on until I turn the truck off. After re starting the truck the lights are both off until I get on the brakes again. I found a person with a scanner and the code came up 63-shuttle reset switch, but neither of us know where it is or what it does. Is this just a sensor switch problem or more involved? Any info on this would be greatly appreciated considering I have a heavy trailer I need to pull Monday

 

Code 63 is for the ABS.
