    You mean you want to monitor the CAN bus? Or access the engine controller (ECU) OBD-II for diagnostics?

    To access diagnostics, you can send the commands:
    ATZ
    ATSP0
    0100

    Then
    ATDP will show which OBD-II protocol is in use (make sure key in, engine off (dash lights on)/ engine on)

    Let me know if you're doing anything more advanced than this?
