4) Using a lead wire with alligator clips ground the No. 10 terminal of the self-diagnosis connector (behind the glove box)


I think this step is incorrect.
Just saying... so everybody gets the best information...
Always open to debating this or other topics.

(There was and FSB or something that outlines why the "Dealer Scam Tool" couldnt be used for tune-ups...because it grounded #10 pin.)


Huh. That's interesting! I wonder what grounding the #10 pin does? I would conjecture that doing this prevents the ECU from trying to step the ISC while you are adjusting the base idle? I grounded the pin when I set my base idle speed a while ago (before finally replacing the ISC). It didn't seem to cause any problems...

Do you or anyone else have a copy of that FSB (TSB?)? I'd be interested in reading it...
