AUDIO AND VISUAL SYSTEM(except 8 Speakers) OPERATION CHECK


  1. REMOTE TOUCH SELF CHECK

    Note


    • Before entering self-diagnostic mode, make sure there are no obstacles which may interfere with operation of the remote touch screen, and that the touch screen is not dirty.

    • Do not touch the touch screen except when required.

    • Since the remote touch screen may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the remote touch in self-diagnostic mode.

    Tech Tips

    The following checks can be done via the self check:


    • DTC check for the remote touch

    • Switch illumination check

    • Touch screen operation position recognition condition check

    • Switch operation check

    • Vibration feedback generation condition check

      *A for RHD
      *B for LHD
      *a "HOME" Switch
      *b Touch Screen Press Operation

      Activate Self-check Mode


      1. Set the light control switch to TAIL.

      2. With the frame of the touch screen and "HOME" switch pressed, turn the engine switch on (ACC) and enter self-diagnostic mode.

        Note

        If the frame of the touch screen is not pressed to enter self-diagnostic mode, a self-diagnosis cannot be performed properly.

    2. Switch Illumination Check and DTC Check


      1. B0059T7C02
        *a Switch Illumination

        Check that the switch illumination turns on.

        Tech Tips

        When DTCs are stored as present DTCs during the self check, the switch illumination blinks at 0.5-second intervals. The illumination will continue to blink until the self check is completed.

    3. B00575GC02
      *a Lateral Axis
      *b Longitudinal Axis

      Touch screen operation position recognition condition check


      1. Operate the touch screen laterally and longitudinally and check that the brightness of the switch illumination changes.

        Tech Tips


        • If the brightness of the switch illumination changes according to the touch screen operation, the touch screen operation position is correctly recognized.

        • The brightness of the switch illumination changes between 0% and 100% according to the touch screen position coordinates.

        • The touch screen position coordinates change between 0 and 255 on the lateral axis and longitudinal axis.

        • When the touch screen operation position coordinates are Lateral Axis: 0 and Longitudinal Axis: 0, the brightness of the switch illumination is 0% (off). When the coordinates are Lateral Axis: 255 and Longitudinal Axis: 255, the brightness of the switch illumination is 100% (illuminated).

    4. Switch Operation Check


      1. Check that the switch illumination turns on at 100% when each switch is pressed with the touch screen operated at the lower left position.

        Tech Tips

        If the switch illumination turns on at 100% brightness when a switch is pressed, the switch being pressed is operating normally.

    5. Vibration feedback generation condition check


      1. B005B0PC03
        *a Default Feedback Force Image
        *b Button

        Operate the remote touch screen to move the pointer displayed on the multi-display assembly screen and check the remote that touch screen generates vibration feedback according to the display screen and pointer display position.

        Tech Tips


        • If the remote touch generates vibration feedback according to the display screen and pointer display position, the remote touch is correctly receiving the reaction force setting signal sent by the radio receiver assembly.

        • If the remote touch cannot receive the reaction force setting signal sent by the radio receiver assembly, use the default feedback force image stored in the remote touch to generate vibration feedback on the touch screen.

    6. End Self-diagnostic Mode


      1. Wait 30 seconds without performing any operations or turn the engine switch off to end self diagnostic mode.

    This function is used to check the connection history when the connection between the radio receiver assembly and a "Bluetooth" device is unstable.

    CHECK "Bluetooth" CONNECTION HISTORY


    1. Check "Bluetooth" Connection History.

      Tech Tips


      • "Bluetooth" Connection History displays data stored in the internal memory of the ECU, such as the date a "Bluetooth" connection was attempted and the progress of a "Bluetooth" connection.

      • By checking "Bluetooth" Connection History, the date, cause, etc. of a "Bluetooth" device failing to register or connect can be analyzed.

      • "Bluetooth" connection history indicates the estimated cause of a malfunction, but does not determine it. Therefore, checking "Bluetooth" Connection History may not improve the problem.

      • Performing inspection using the GTS before recording the "Bluetooth" Connection History may clear the operation history.


      1. Connect the GTS to the DLC3.

      2. Turn the engine switch on (IG).

      3. Turn the GTS on.

      4. Enter the following menus: Body Electrical / Navigation System / Utility / Bluetooth Connection History.
