ABS light is on all the time. if i hook my trailer up to the truck the ABS light goes out and stays off as long as the trailer is hooked up. i checked all the fuses and all seem good. any suggestions. could the electric brake box in the truck be bad it self? sorry for posting all at once its just my account was not working before.

Sounds like a wire is crossed somwhere.... Or the ABS controller is bad. But if that was the case, I would think the light would stay on ALL the time. Does you ABS system work???

i removed the brake controller box and wired in a box i had in my tool box. i have not plug it to the truck harness but the light is off so far. tom i will hook it up and see if the box did anything or not.
