I have a 2000 Blazer 4dr 4x4. I am pulling C0246 code only. The abs was sticking on and you would have to tap the brakes and it would go off..at near stopped speed. Finally it quit and put up CO246. I cleaned ground on the radiator support but no help. Replaced left wheel hub..get wheel speeds on both wheels with scan tool. I am lost any help would be appreciated.
