On-Board Diagnostics = ODB. An ODB-2 computer stores diagnostic information about your car, most of it pertaining to emissions, but some of it being useful for tuning perposes and such. AN ODB-2 reader is usually used to pull diagonistic information off of the computer as trouble codes. THey'll have codes for all sorts of things, like misfires, bad O2 sensors, etc.

There are a ton of people out there that sell ODB-2 cables and software for Palm devices and PCs. I don't know if 986 is ODB-2 compliant or not, and I'm guessing the 987 isn't at all.
