I have a 2004 Denali XL w/ 107k, bought it new, no accidents or major issues, drove it normal all weekend like usual and on Monday morning as soon as I started it up I got Service Stability Message & ABS Light & TC Traction Control Light, the lights are now on constantly everytime I start the truck, brought it to my local mechanic and he said the ABS code said the ABS pump motor was seized or had a short, I have never heard the pump running excessive or anything of that sort.. anyone have any ideas?
