You will need some sort of scan tool, or access to someone who has one. I believe there is a thread somewhere about all the members who have them and where they are located. www.autotap.com has a good one that requires a laptop or palm device and there are a few others on the net if you do a google for obdii scantool. Autotaps software and hardware combo runs about 270 i think.

Ok...My buddy has an odbII for his car, so I will just use his...

Thx..

Make sure it supports GM models, also some do and some dont support extended parameters. I'm not sure if KR is a generic parameter or not so you will just have to try it i guess.
