NAVIGATION SYSTEM SYSTEM NORMAL CONDITION CHECK


  1. CHECK 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 navigation receiver assembly 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 hybrid system starts, the navigation system deviates from the correct position. If the vehicle starts before the navigation system activates, the system may not react.
      When running 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 map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.
    2. A003SO4

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


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

      2. A003T0N

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

      3. A003TKR

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

      4. A003UIM

        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 GPS.

      5. A003UAV

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

      6. A003V05

        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. A003U3M

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

      8. A003TGH

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

      9. A003UKU

        When the vehicle runs 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. A003RT2

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

        Tech Tips


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

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