I have a 2002 Civic and I just bought an OBDII ELM327 adapter with OBDII cable but now I need some software to load onto my notebook so I can check my PCM for error codes.

I know that tuning software isn't free but i'm hoping that simple scanning software to check codes, that there is a free one. If there isn't a free one I'll pay for the best. Thanks!

Yeah I'm a newb, lol.
