Is it an old data link or an obd2? 

When I brought my mc2 the abs didn't work, mine has a data link connecter, I found a 0bd2 conversion lead on the net an got it plugged in at local garage. Had 1 dead sensor on front and intermittent on the rear. 

When I got second hand ones an replaced it was still no good, so I got the car in the air again an head a wire brush on the abs ring on the shaft to clean it up, then took the car for a spin an locked the breaks, the abs then started working
