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


    1. A00ONYP

      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.

      • A00OKTG

        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

    Tech Tips


    • ○: Stored.

    • X: When one side of CAN branch wire is open, storage may occur.

    • -: Not stored.

    • *1: During a communication stop, cannot be stored.

    • *2: Only stored when communication with both ECUs is lost.

    • *3: With gateway function.

    • ECB*4: Electronically Controlled Brake System
