Try one of the tools from http://www.iequus.com/
. I have one of their tools that reads OBD I, 2, & CANBUS. You can pull and store the codes in the tool and then take it to a pc and use their software. You don't have to have the tool to look up the codes, it just makes things easier. If you have any questions about it, I can get better answers once I get home.
