i bought a little hand held code reader from the mac truck, does alright. its not fancy or anything, gives me basic codes and i can also erase them. it was something like 50 or 60 dollars.
I just posted some update comments on AutoEnginuity scanner issue above. Not sure how to bring it into your question. Maybe check with the folks at http://www.autorepairmanuals.biz/, They have a good selection, though not the really cheap stuff, and I thought their advice to me was useful in choosing a scanner.
If you're on a budget, you'll want a code reader. Scan tools are more expensive but they can do a lot more than a basic code reader.
I've had very good luck with EQUUS products. They make very reasonable code readers at a decent price....SEARCH the web and you'll find their stuff everywhere.
New Law for 2010
Parts stores in CA and HI aren't allowed to scan or rent code readers.
It's suspected that people were trying to pass smog buy clearing the codes. How stupid is that..you've still got to fix the problem
I can't wait until our illustrious "acting" Governor is booted out...
I have the Actron one too, don't know the part # but it's the palm size one. Costs like $60 or so at any auto parts chain store, Autozone, Advance auto, Pep Boys, Strauss. It does let you reset codes.
