I have a 2002 Chevy Tahoe LT with the 5.3 v8. I took my tahoe to the dealership to find a ground problem. When I got it back i was driving down the road not even a block away and now my ABS and Brake light are on. When driving I get a loud grinding sound coming from my drivers side front wheel. I check to see if it was a wheel bearing going out and it was not. I took it back to the dealership and they told me my EBCM was bad and it was going to cost me $1000 for the part and $150 for labor. The code they claimed it was throwing was C0265 or motor relay circuit is what they wrote down. Im almost wondering if it is not the ABS control module and maybe something else. I checked the ground going from the ABS control module to the frame rail. I took it off grinded down the surface and put it back on and sprayed it with some undercoating. So its not a ground issue with the EBCM. I still dont know why there is the awful grinding noice coming from the wheel. Please someone help me with this issue. I am in need of some desperate help.
