Only thing I did to make this happen was cruisin to work one morning people in front of me locked up brakes so I had to slam on mine, the abs, traction, stab service fault lights come on. After the 4th start it will go out but if I restart truck, back on it came, took to dealer today said needs ebm electronic brake module, ordered part, take back up there tomorrow.... will see, I read both colorados and canyons having bad issues with this.
