You can do it with a tool I use from AUTO ENGINUITY.COM It's their PC-based scan tool. Just load their disc into your pc for the software you need & hook up the OBDII connector to your car & follow the supplied handbook. You can run snapshots of your car, graphs, all kind of diagnostic goodies. Theres even a built in prog. for track & strip use by inserting your cars tire size, third member ratio etc. It's too expensive just to use to clear a CEL light or to find out what a code means. Mine was about $250.00 a couple of yrs. ago. Log onto their web site above to see if it's for you. I am in no way connected to this company period. One serious downfall using your P.C. as a scan tool is if you live in a cooler climate part of the year your P.C. screen will more than likely fade away when leaving a warm house & going into a cool to cold garage or outside setting. I never thought of this before ordering my setup. Good luck.
