  1. Check the ground connection at the front left side of the frame,behind the bumper area,this is the battery to frame ground. That's one of the three grounds that I took apart, cleaned up with a drumel wheel and reattached. The second one was on the front driver side cab mount (just in front of the EBCM) and the third one is in the back just behind the gas filler door.
  2. I have a 2000 GMC Sierra 1500 with the same problem. I've cleaned and reinstalled the three grounds I could find along the frame with no luck. My son printed a picture of gound 110, which according to his source is located on the front shock mount... no such ground exists on any GM product I've looked at. I've had a Snap-On scanner give me codes CO265, CO245, CO241. CO251, CO246 and CO242. All of them seem to be connected with the ECBM. The only codes with any suggestions to them want you to check the 10 pin and 2 pin connectors, which I'm assuming the 2 pin connector is the one located on top of the shock mount and connects the wiring harnes to the lead that goes to the sensor in the front wheel hub. My Brother-in-law says he's seen this kind of problem and it usually is a bad wire connection in the front bearing hub (he said you wouldn't believe how small a wire they use for this connection) and replacing the front hub/bearing solves it. He also mentioned that an ABS brake scanner will pinpoint which side is causing the problem... is an ABS Scanner going to give me a better reading on the system? Anybody have any other input... I'll be cleaning the 2 pin connectors today and will let you know what happens.
