ABS Problems
 

Ok everyone I need your help again. I have a 1993 S10 Blazer with the W engine 2 wheel drive in it. It also has ABS and at present time I have the ABS & Brake light on and I am pretty sure that the ABS unit is not working is there some dianostic connection like the Dianostic connection for the enigne and if so how can I read it? My breaks work ok But would like to get the ABS system working also. any help would be great. Thanks
