    Since I added Y connections to make the under-dash connector available while the OBDLink devices are plugged in (details here), I can run PriiDash in ATMA Only mode to listen for the OBD queries during the annual state inspection. Here is a list of the query commands:
    Code:
    7DF 02 01 00 00 00 00 00 00 PIDs supported [01 - 20]
    7DF 02 01 00 00 00 00 00 00 PIDs supported [01 - 20]
    7DF 02 01 20 00 00 00 00 00 PIDs supported [21 - 40]
    7DF 02 01 40 00 00 00 00 00 PIDs supported [41 - 60]
    7DF 02 01 01 00 00 00 00 00 Monitor status since DTCs cleared. (Includes malfunction indicator lamp (MIL) status and number of DTCs.)
    7DF 02 01 1C 00 00 00 00 00 OBD standards this vehicle conforms to
    7DF 02 01 01 00 00 00 00 00 Monitor status since DTCs cleared. (...)

    7DF 02 09 00 00 00 00 00 00 Mode 9 supported PIDs (01 to 20)
    7DF 02 09 04 00 00 00 00 00 Calibration ID
    7DF 02 09 00 00 00 00 00 00 Mode 9 supported PIDs (01 to 20)
    7DF 02 09 02 00 00 00 00 00 Vehicle Identification Number (VIN)
    7DF 02 09 04 00 00 00 00 00 Calibration ID
    7DF 02 09 06 00 00 00 00 00 Calibration Verification Numbers (CVN)
    7DF 02 09 00 00 00 00 00 00 Mode 9 supported PIDs (01 to 20)
    7DF 02 09 04 00 00 00 00 00 Calibration ID
    7DF 02 09 06 00 00 00 00 00 Calibration Verification Numbers (CVN)
    
    It looks like the main ones are mode 1 PID 01 for status since DTCs cleared, and mode 9 PID 04 and 06 for calibration data.

    Anyone knows Toyota specific command for reading VIN? I sent 09 02 command to my Toyota Corolla Altis (CAN bus) and it returned all FF
