Does GM have a proprietary scan tool?
I fired up VAG-COM, which is a Porsche/VW/Audi scan tool I have, but it includes a generic OBD2 scanner as well.
When I connected it to the car and picked the generic scan tool, it still didn't work.
Is there a special tool needed to scan this motor? I'm going to head over to the neighborhood auto parts store tomorrow morning to see if they can scan it...
I'll see if the auto parts store can read the codes. If not I may have to hit up a friend who's a service writer at a local Chevy dealer.
