I use a actron scanner. It works well and cheap. Here's a ebay link 45 shipped. I think you can even get them at about any auto part store.

Cipher.

Ho. That's good. Does it erase also?

i got an actron, does what its says, cipher if u got the cash and time to hookup to laptop and check all the jazz. actron is quick, simple and 1/4 the price. i only use it to check/clear codes and it does that so im happy. cipher will give u more data but dont know if its worth it if u just want to clear the check engine light

i got the larger actron unit which gives u the code # and a short descripion of the issue

I just ordered the actron, thanks guys!

It does erase codes. for the money it's well worth it.

FWIW, I have this one I know you can get them off the trucks for $50

^ oh that's what the one of my buddy had it.

I have the actron pocket scan, too. great little unit. it is small with a short cord....perfect for keeping in the car and quickly erasing codes. easy enough to do (even while driving!!)
