Electronics Geniuses? How are error codes sent ?

hey guys.....

just wondering how the error codes are delivered to the computers at the dealer? is it a serial thing, coded pulses, sometihng else?

i ask because i just got some programable microchips and i could easily set up a little LCD screen in the cab of my jeep that constatnly monitors the codes.....and then displays in text whats wrong ....i think it'd be sweet...and not expensive either.

let me know if you know!

1. You've got the OBDII compliant ECM...
2. On that one... I ain't got a clue,
3. It's much more involved than OBDI.
