I just bought a 2005 chevy duramax with a 6 inch lift and superchip, the abs light won't turn off I have a code for the abs module and have replaced it twice. Its still on. Speed sensors are good. The truck has 20 inch wheels with 37 inch tires I have programmed the superchip to 37 inch tires. Is there some simulators out there that I need?? Has any one experienced this before?? :confused:

Have you tried checking the sensors for each wheel for the ABS, might just be a possible sensor for the ABS that's going out triggering the light to come on.
