Scott,
Best place to start for the OBD_II stuff is SAE... Pick up their HS-3000
handbook.  Has all the protocols, formats etc all layed out.
There are 3 "flavors" of OBD_II communications... GM uses 1, Ford another
and chrysler the 3rd.  For a standard, It's not really... Still gives the
manufacturers leeway to make it what they want.
