I've discovered a way to trouble shoot the ABS Diagnostic Trouble codes (DTC) by using the ABS warning lamp. Basicly you jumper pins 12 and 4 of the OBD II scan port (DLC), turn the key switch to the on position. The ABS light will flash out the DTC.
Attached is a link to a .pdf file I created that gives the procedure with the DTC code descriptions. The description identifies the components that are the source of the problem.
