AUDIO AND VISUAL SYSTEM(for 8 Inch Display) OPERATION CHECK


  1. REMOTE TOUCH SELF CHECK

    Note


    • Before entering self-diagnostic mode, make sure there are no obstructions which may interfere with operation of the remote touch switch knob, and that the remote touch switch knob is not stuck.

    • Do not touch the remote touch switch knob except when necessary.

    Tech Tips

    The following checks can be done via self-diagnostic mode:


    • Remote touch DTC check

    • Switch illumination check

    • Remote touch switch knob position recognition check

    • Switch operation check

    • Remote touch switch knob feedback force check

      Activate Self-diagnostic Mode


      1. While pressing and holding the down switch, turn the engine switch on (ACC) to enter self-diagnostic mode.

    2. Switch Illumination Check and DTC Check


      1. B002EDMC01
        *a Switch Illumination
        *b Switch Knob

        Check that the remote touch switch knob automatically moves to the center of the movable area and that the switch illumination blinks.

        Tech Tips

        During self check mode, all check mode DTCs are stored and the switch illumination blinks at 0.5-second intervals. When the clear conditions for each DTC are met, the DTC is cleared. The switch illumination continues to blink until the self check is complete and all DTCs are cleared.

      Remote Touch Switch Knob Position Recognition Check


      1. Move the remote touch switch 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 position of the remote touch switch knob, the remote touch switch knob position is being correctly recognized.

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

        • The remote touch switch coordinates change between 0 and 255 for both the lateral and longitudinal axis.

        • When the remote touch switch knob coordinates of both the lateral and longitudinal axes of the remote touch switch knob are 0, the brightness of the switch illumination will be 0% (off). When the coordinates of both the lateral and longitudinal axis are 255, the brightness of the switch illumination will be 100% (full brightness).

    4. Switch Operation Check


      1. Check that the switch illumination turns on at 100% brightness when each switch is pressed while the remote touch switch knob is in 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.

        Tech Tips


        • Refer to Remote Touch Outline for further information on the remote touch switch knob feedback force.

          Click here

        • If the remote touch generates remote touch switch knob feedback force according to the pointer display position, the remote touch is correctly receiving the feedback force setting signal sent from the radio receiver assembly.
