You would need one of these two capes to start with:

http://circuitco.com/support/index.php?title=TT3201_CAN_Cape
http://circuitco.com/support/index.php?title=BeagleBone_CANBus

Then you would need to figure out how to mate the pinout of the connector on the cape with the OBDII connector. I don’t know how, but Google should be able to tell you.

You also need to check for BB Black cape compatibility. If you search this forum there should be multiple messages about cape compatibility with the Black that should give you a link to a wiki page with more detailed information. Sorry I don’t have the link handy but I’m packing up to leave work.

I appreciate everyone's responses - I didn't expect so much feedback so quickly!

I was able to find the pinout for the obd2 port fairly easily.

Does anyone know of there are any cheaper (usb) alternatives to using one of the expensive capes?

Not cheap… we use PEAK at work, but you will have to spend quite a bit more than the CAN cape.

USB? the Can tranceiver chips are connected to the DCAN controller via the bone header
You have to do some circuit design I just opened mine up they plug on top of the bone using male connectors you could look at the cape schematics as reference of how to breadboard this or ask the previous poster if he will share his design

If you are in Europe, 8devices.com sell a USB2CAN device for about 50 Euro.
