If you have an Android Smart phone you can use a Torque App and EML327 bluetooth reader to read and reset the codes. Torque App also provides you with a full range of engine parameters. You can build an instrument panel with it. I use to accurately track water temperature and boost in one of my cars.
Google EML 327 for the reader. They range for $10 to $100. The cheaper ones sometimes have more trouble connecting to the phone. The reader is good for OBD 2 systems (1996 and latter engines)
The Torque App has both a free version and a $5 version with more data.
