NAVIGATION SYSTEM OPERATION CHECK


  1. CHECK NAVIGATION SYSTEM NORMAL CONDITION


    1. If the cause of a symptom is any of the following, the corresponding symptom is normal; it is not due to a malfunction.

      Symptom Answer
      A longer route than expected is chosen. Depending on the road conditions, the navigation ECU 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 internal memory, the system attempts to match it to another nearby road, causing the position mark to deviate.

      The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor or navigation ECU.


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

      2. B0070BM

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

      3. B006WT5

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

      4. B006ZN9

        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. B006Z6U

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

      6. B0071DV

        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. B007061

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

      8. B006WZH

        When the ignition switch is turned to ACC or ON 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. B006XK8

        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. B006XXL

        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. STORAGE CHECK (DCU STORAGE CHECK)

    Note

    When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:

    • The radio and display receiver assembly may not operate normally.

    Tech Tips


    • Check the storage with it installed to the radio and display 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.

      • OK: Connected properly

      • NG: Not connected properly

      • -: Not equipped with digital TV antenna

      Tech Tips


      • As digital TV is a terrestrial broadcast, the digital TV antenna cannot receive the signal in places where the signal may not reach the vehicle, such as mountains or tunnels.

      • Even in areas where digital TV broadcasts for households can be received, the in-vehicle digital TV may not be able to receive the broadcast.


      1. Select "Recheck" to start the DTV reception check.

      2. Check the result displayed when the DTV reception check is complete.

        Tech Tips


        • Do not depend solely on the reception level as a reference value as it may vary depending on signal conditions such as wave interference.

        • If the result changes after turning the vehicle around, it is not due to a malfunction, but is caused by a local weak electric field.

        • If the reception level is abnormal, the antenna system or radio and display receiver assembly is malfunctioning.

  12. CHECK DAB RECEPTION (w/ DAB Function)
