Re: 96 Chevy Cheyenne speedometer stopped working
Again, Thanks... I think that is what was throwing me a bit. I had read somewhere that part of the signal for the speedo runs through the ABS. The ABS is working fine with exception to significant wear on one of the rotors... and I'm not kidding when I say that some of the fins inside the rotor are totally gone and parts of the rotor are missing... you can feel them operating as if they were compensating for those missing fins. So, answering my question if I understand you correctly- If there was damage to that sensor on the brake and/or the VSS sensor was defective, then my ABS would be OFF? I guess I am thrown off a bit in assuming that if I had a bad wire or something grounding out, the ABS would still be OFF (under the assumption that the vss, speedo and brake sensor could not communicate) and the ABS seems to be fine.
All that said, I guess I'm asking for the extra effort in putting it into idiot's terms! Also, my statement on the OBD II reader not being able to detect the protocol.... any insight as to why it's powering up, but not able to read anyting?... very possible that pulling a code would answer my question of whether to be looking at wires or just replacing the VSS.
