Default ABS System Test Repeating

Occasionally the ABS system test that normally occurs once at approx. 3 MPH, will happen every time the car slows to 3 MPH. This may occur 10-12 times while driving when I slow to stop. The brakes seem to work fine. This is on a 1988 Vette. Any ideas?

Most likely the ABS computer is at fault. Call around to Chevy dealers and see if you can find one that still has a C4 ABS tester, it will at least find where the problem is.

Default Found The Problem

The problem turned out to be a wheel sensor. The wheel sensor was on the left rear and tested fine with my hand meter. I was suspect of it because the wheel bearing on this wheel was bad and I replaced it a month ago. It was driving me crazy. Hope this helps someone in the future.
