I was looking to get a basic OBD II code reader program for my PC that I can use to read basic trouble codes, reset CEL & service inerval lamps, etc. I have found a couple of versions for PC as well as PDA. Is anyone using anything right now that works well? Any recommendations or suggstions?

I probably wouldn't fix too many things on my own, but it is nice to know what's wrong before you take it in. This way I don't have to spend $75 to hear that my O2 sensor is bad.

Autozone, etc. will read and reset your codes for free if necessary. You also don't need a code reader to reset the service reminders. That being said, I have an OBDII reader that plugs into the port under the dash. My guess is that it reads maybe 5% of the available codes which I think is typical. If you really want to do it right, you need to get the code reader that reads off of the 38 pin connector under the hood. That reads every code from every system, assuming you have the appropriate software. Problem is the 38 pin connector unit with the software runs into five digits as far as I can tell. The under dash plug in can be had for about $100.

I bought a ISO scan tool from :http://www.scantool.net and worked fine on my 1998 SLK230.
I used a Palm m130 to connect. You can use a laptop or a PC too.

You can read all the codes and clear them.
you can also real live data from the OBDII.

Cheers
