CAN COMMUNICATION SYSTEM (for LHD without Entry and Start System) DIAGNOSIS SYSTEM


  1. BUS CHECK (COMMUNICATION MALFUNCTION ECU)

    Only CAN communication system DTCs for each ECU can be output to the intelligent tester.


    1. A01DLYV

      Select "Bus Check" from the "System Select" screen on the intelligent tester.

    2. A01DRVF

      Select "Communication Malfunction DTC" from the "Bus Check" screen, and then select "Enter".

    3. A01DSDV

      Select the system of the DTC to be checked and select "Details".

    4. A01DRVG

      CAN communication system DTCs are output.

  2. BUS CHECK (COMMUNICATION BUS CHECK)

    Tech Tips

    The ECUs and sensors that are properly connected to the CAN communication system can be displayed using the intelligent tester.


    1. A01DRVF

      Select "Communication Bus Check" from the "Bus Check" screen.

    2. The screen displays the ECUs and sensors that are properly connected to the CAN communication system.

      Tech Tips


      • If any properly connected ECUs or sensors are not displayed, there is a communication stop in the system Click here.

      • A01DRA1

        The default item displayed in the combo box is "ALL". When checking the ECUs (sensors) connected to each bus, pull down the combo box and select the bus to be checked from the drop-down list. The drop-down list displays "ALL", "V Bus" and the names of the remaining buses.

        Combo Box Display Content
        ALL All ECUs (sensors) connected to the CAN bus
        V Bus ECUs (sensors) connected to the V Bus
