NAVIGATION SYSTEM (for HDD) OPERATION CHECK


  1. CHECK SYSTEM NORMAL CONDITION


    1. If the cause of a symptom is any of the following, it is the 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 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 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 data, 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, speed sensor and navigation receiver assembly.


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

      2. A006DTT

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

      3. A006GAE

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

      4. A006HYN

        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. A006G00

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

      6. A006GVR

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

      7. A006HQM

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

      8. A006FKF

        When the ignition switch is turned to ACC or ON 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. A006FVO

        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. A006FW3

        When a tire is 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.
