  1. CHECK SYSTEM NORMAL CONDITION 
    1. If a symptom is any of the following, it is not a malfunction
      DIAGNOSTIC TROUBLE CODE

      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 actual 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 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
    2. The following symptoms are not a malfunction, but are caused by errors inherent in the GPS, gyro sensor, speed sensor, or navigation ECU
      1. The current position mark may be displayed on a nearby parallel road
        Fig 1: Symptoms - Current Position Mark May Be Displayed On Nearby Parallel Road

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

        HINT

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