NAVIGATION SYSTEM (for DVD) OPERATION CHECK


  1. Check System Normal Condition


    1. If the cause of a symptom is any of the following, the corresponding symptom is normal; it is not 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 paths 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 actual 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 actual position. When the vehicle is driving on new roads not available on the map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.

      The following symptoms are not a malfunction, but are caused by errors inherent in the GPS, gyro sensor, speed sensor and navigation ECU.


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

      2. A00DR6D

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

      3. A00DU4S

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

      4. A00DSEF

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

      5. A00DUFK

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

      6. A00DUCI

        When the vehicle makes a continuous turn of 360°, 720°, 1080°, etc., the current vehicle position mark may deviate from the correct position.

      7. A00DRKZ

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

      8. A00DR5NE02

        When the ignition switch is turned to ACC or ON on a turntable while parking, the current vehicle position mark may not point in the correct direction. The same will occur when the vehicle starts to move.

      9. A00DQRP

        When the vehicle is driven 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. A00DSRZ

        When a tire is changed, the current vehicle position mark may deviate from the correct position.

        Tech Tips


        • The diameter of the tire may change, causing a speed sensor error.

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