HELP!!!! I have a ABS Mystery

I have a 1998 C5 and have a ABS problem I just can’t fix.

The problem is when I slam on the brakes the car locks up one front wheel and you can hear the pump working as you skid to a stop then the DIC say “ABS is Activated”. Then I do it again and the other wheel skids as I come to a stop. Now I have a new pump and a overhauled control unit. No codes and everything checks out so far. Any ideas?

Wheel speed sensors? But that would probably cause a code...

If that's true STOP posting new threads. It'll be a lot easier to discuss your issue if we're all in the same place.

Check your brake line at the wheel that's locking up. The rubber brake lines will fail internally eventually...

Please pull all of the codes from the DIC and post them. Be sure to include any "H" or "C"s with each code.
