I have an Actron that works just fine. As Greg said, they won't read the
manufacturer extended codes (chassis, special controllers, etc.), but
they will read the basic engine codes.

I have an indy mechanic that has the Chevy specific tool. He read the
codes on the 'vette when the brake and traction control module went out.
It was still under warranty, so he sent me off to the dealer and didn't charge me a dime.

The 'vette is now gone and an Audi A6 has taken it's place. It has the
same issue as all new vehicles in that the reader only pulls the most
basic codes. The aftermarket reader for it is a $350 software and cable
package you run on a laptop. It allows you access to a ton of features
and settings that only the dealer can see. Stuff like turning on the
window up/down from your keyfob, internal and external lighting settings,
playing DVDs on the screen while moving, etc. And many service modes,
too. With the 100k mile warranty, I doubt I'll pop for it, though.
I have an Innova 3030. Reads and resets codes and has a connection for a
PC and a CD. Never used the connection. Works great. I bought it when
the truck went into limp mode, and the dealer could not find a problem.
Reset code and 40 miles later in Sacramento, limp mode again. Bought the
reader and went to McD's for free WIFI and found out there was a bad
connector on number 7 injector. Even a fix for the bad connection. Well
worth owning one.
