I have a 2004 Silverado 2500 . Recently the ABS warning light came on, and when I shut off the ignition, the ABS Module kept buzzing so I had to pull its fuse. Can a code reader distinguish between a faulty ABS Module, a faulty reading from one of the wheel sensors and /or some type of a wiring fault?

 

Welcome to the forum. I think you will need to get a special ABS scanner. Probably get a more definite answer in the Silverado section of the forum.
