You're assuming the problem has been solved. I couldn't get the ABS light to clear in my '93 'Burb. I'd just done new rotors and calipers, what could be wrong? I eventually came to the realization that the parts house had given me an unmatched 'pair' of new rotors: one with the toothed sensor ring and one without. I'd failed to notice the difference during installation, but the internal code cops didn't.Disconnect the positive battery cable for a couple of minutes. 94 and older vehicles are OB1 and don’t need a scanner to clear codes.
