OBD II
I googled 'OBD II' a while back and found these:

They should get you started... -
CHECK ENGINE light, et alI looked at the OBD-II, but decided that I didn't want to lug my laptop everywhere so I went with the Equus OBD-II Reader instead. I mean I could take it to the dealer and pay 75 bucks, or pop my battery cable; but where's the fun in that?
Does anyone know of any low voltage led sequencer designs for driving fiber optic strands in sequence?
I'd like to spice up a Star Destroyer and maybe a few other spaceships! -
Re:In response to many questions
There are several companies that build interfaces to go from the OBD2 protocol to an async serial stream you can connect to a laptop or PDA

Re:Why spend $6000 for a computer with a cable?
http://www.obd-2.com/ is your answer. About $150 and you can interface with any of the 3 main OBD-II interfacing protocols. Downloadable updates. Error code sets for your manufacturer. Tons of information. And the author has a very impressive resume when it comes to automotive and computer diagnostic design!
Mix this with a little bit of community-brainstorming on an automotive message board, and most car problems can be solved.Not having the tools to fix something is a whole other issue :) Software has a hard time transforming into a torque wrench! -
Re:What I'd like to see.
Oh, I know how to do this! I just bought an adapter plus software to interface a PC to the on-board computer. This thing works like a charm.
I don't know that all on-board computers know when the oil was changed or coolant was flushed, but I'm sure a couple perl script could take care of schedule maintenance. -
Re:Their goal...
That "black-box" is available. Check this out. The whole rant is sort of flawed, because there is actually a standard for car diagnostic interfaces, called ODB-2. I had a link to the documentation, but can't find it right now.

Hack your car's computer...
You can't hack your car's ecu with linux, but you can hack your car's ecu with your palm

Most OBD2 in Japanese cars is synchronous serialAnd at a really funky baud rate, like 4312. You have to buy the right chipset and set it up just right. If your time has value, look for the manufacturer's diagnostic consoles on ebay or something. It'll be cheaper.
