    J1708 and OBDII in same vehicle

    Why would a Ford F650 have both and what would be available on each?

    It is made by Navistar and uses heavy duty diesels, that explain why they have both, OBD for EPA requirement, J1708 for dealer diagnostic and service. There should be a J1939 on the same vehicle as well. Can you confirm?
