I had a quick look through and the checks from page 75 to the end definitely tie up to the normal ABS Module pins according to the cct diagram. Unfortunately these are mostly the same checks that Jon @ work has already listed. I am assuming you do have a diagram of the system. I have not traced through the cct to see what the effect of a shorted or open diode would be but I do see there are a few diodes in the system, including one in the warning indicator circuit. Have found in the past you can sometimes use these system test manuals to work out what part of the system they are checking with the breakout box and finding that item on the circuit diagram and finding which pins on the module to check on.
