1994 full size blazer ABS codes
 

codes 41, 42, 45, 46, 51, 52 which are according my research "control valves"
code 65: open or shorted pump motor relay
code 67: open motor circuit or shorted BPMV output

if these are inaccurate please correct me.

this is a 1994 Chevrolet full size blazer 5.7L gas TBI 4wd. if I am missing any useful information please tell me.

I have an abs light obviously. I just shorted pins A-H and all of these codes are what I got. From my current researching if you have code 65 but you also have a wheel speed sensor code, then you maybe only have to replace the wheel speed sensor that is bad. In my case, my wheel speed sensors are not throwing any codes. Any experts in here know what my first course of action at this point should be? Do I buy a new ABS control module, do shops repair these things, or can I do it at home? I do a lot of work on my vehicles at home but as far as braking goes, the only repairs I have ever done are a brake light switch replacement, light bulbs, and brake pads. I have never bled my own brakes since I have never actually had to. So just trying to get an idea of what I am in for on this.
