I have a 2005 GMC Sierra. My ABS light has been on for several days. I took it to the dealer and they said it will be $150 just to diagnose the problem, thats just to figure out the problem thats not to fix it. On top of that I will need to pay to fix it (weather its big or small). Still, I dont want to pay this much. I have checked the brake fluid level of the master cylinder, and thats ok. Next I am going to check the four sensors. I was wondering other than checking the sensors what else can I look for? Is there some sort of diagnostic tool I can buy to help figure this out and do it myself? What else can I check.??? By the way my brakes feel fine, I just want the light off! Thanks
