NAVIGATION SYSTEM OPERATION CHECK


  1. CHECK NAVIGATION SYSTEM NORMAL CONDITION


    1. If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.

      Symptom Answer
      A longer route than expected is chosen. Depending on the road conditions, the radio receiver assembly may determine that a longer route is quicker.
      Even when distance priority is high, the shortest route is not shown. Some routes may not be advised due to safety concerns.
      When the vehicle is put into motion immediately after the engine starts, the navigation system deviates from the correct position. If the vehicle starts before the navigation system activates, the system may not react.
      When driving on certain types of roads, especially new roads, the vehicle position deviates from the correct position. When the vehicle is driving on new roads not available on the SD card (disc player disc), the system attempts to match it to another nearby road, causing the position mark to deviate.
      Expected arrival time is earlier than current time, or time different from expected arrival time is displayed. If a destination is set to a point where a different time zone is used, the system displays an expected arrival time corresponding to the time zone of the destination. If a location on the sea is set as the destination, the system may display an expected arrival time corresponding to the time zone setting of the vehicle. Check which communication is not used for displaying traffic information.

      The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor or radio receiver assembly.


      1. The current position mark may be displayed on a nearby parallel road.

      2. A01W071

        Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.

      3. A01W0HS

        When the vehicle turns right or left at an intersection, the current vehicle position mark may be displayed on a nearby parallel road.

      4. A01W0VW

        When the vehicle is carried, such as on a ferry, and the vehicle itself is not driving, the current vehicle position mark may be displayed in the position where the vehicle was until a measurement can be performed by the GPS.

      5. A01W3U7

        When the vehicle travels on a steep hill, the current vehicle position mark may deviate from the correct position.

      6. A01W11E

        When the vehicle makes a continuous turn (e.g. 360, 720, 1080 degrees), the current vehicle position mark may deviate from the correct position.

      7. A01W378

        When the vehicle moves erratically, such as constant lane changes, the current vehicle position mark may deviate from the correct position.

      8. A01W05G

        When the engine switch is turned on (ACC) or on (IG) and the vehicle is turned on a turntable before parking, the current vehicle position mark may not indicate the correct direction. The same will occur when the vehicle comes out of the parking garage.

      9. A01W2J5

        When the vehicle travels on a snowy road or a mountain path with tire chains installed or using a spare tire, the current vehicle position mark may deviate from the correct position.

      10. A01W1PN

        When the tires are changed, the current vehicle position mark may deviate from the correct position.

        Tech Tips


        • A change in tire diameter may cause a speed sensor error.

        • Performing "tire change" in calibration mode will allow the system to correct the current vehicle position faster.

  2. 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


    1. Activate Self-diagnostic Mode


      1. Turn the light control switch to the off position.

      2. A01W5QCC01
        *a Down Switch
        *b Switch Knob

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

    2. Switch Illumination Check and DTC Check


      1. A01W4H3C12
        *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.

    3. A01W2O8C01
      *a Switch Knob
      *b Longitudinal Axis
      *c Lateral Axis

      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 the lateral axis and between 1 and 255 for the longitudinal axis.

        • When the remote touch switch knob coordinates are 0 for the lateral axis and 1 for the longitudinal axis, 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.

    5. Remote Touch Switch Knob Feedback Force Check


      1. A01W2KHC02
        *a Switch Knob
        *b Movement Direction
        *c Feedback Force

        Move the remote touch switch laterally and longitudinally to check that feedback force is generated.

        Tech Tips

        The motors built into the remote touch generate feedback force according to the direction in which the remote touch switch knob is moved.

      2. A01W5NKC04
        *a Default Feedback Force Image
        *b Frame Area
        *c Icon Area

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

        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.

        • If the remote touch cannot receive the feedback force setting signal sent from the radio receiver assembly, use the default feedback force image stored in the remote touch to generate feedback force for the remote touch switch knob.

  3. CHECK SD CARD (DISC PLAYER DISC)

    Tech Tips


    • Check the SD card (disc player disc) with it installed to the radio receiver assembly.

    • Illustrations may differ from the actual vehicle screen depending on the device settings and options. Therefore, some detailed areas may not be shown exactly the same as on the actual vehicle screen.
