I'm not directly involved with scan tools but I do attend yearly trade group meeting with the Detroit automakers for preview service info on next year's models. The scan tool guys usually have a stack of paper 5" thick for each manufacturer documenting this and that trouble code, flag, etcetera. It's an immense amount of specification that changes yearly. I'll ask around this June to see if I can find anyone interested in lending a hand to you guys.
