I'll ditto that, and add that I've yet to come across an ABS problem that
necessitated any special equipment.  Worse I've ever had to deal with was
on my 200TQA.  Had a helluva time trying to get at an ABS problem, turned
out to be a bad sensor cable that somehow (the Sherlock Holmes in me
suspects it got pinched during a motor mount replacement long ago)  was
broken in the middle of the pristine sheath.  It was an intermittent, 
what made it really difficult was that when I put the car on a lift to
check, the cable would make positive contact and the problem would
correct itself for a while.  It was an intermittent problem, while I
can't prove it, I could swear on more than one occasion I heard Gremlins
under the hood having a good laugh at my expense.

BCNU,
