NAVIGATION SYSTEM (for HDD) OPERATION CHECK


  1. CHECK SYSTEM 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 computer sub-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 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 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 map data from the hard disk drive, the system attempts to match it to another nearby road, causing the position mark to deviate.
    2. A003Y31

      The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor, speed sensor or navigation computer sub-assembly.


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

      2. A003YME

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

      3. A003Y6H

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

      4. A003Y9E

        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. A003ZQ6

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

      6. A003WCK

        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. A003WKP

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

      8. A003W9Z

        When the power switch is turned on (ACC or IG) 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. A003W94

        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. A003XLY

        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. MULTI-DISPLAY OPERATION CHECK

    Note


    • Before performing the multi-display operation check, check for obstacles or protrusions which may interrupt opening/closing of the display and foreign objects stuck in moving parts or the multi-display switch. Remove any obstacles or foreign objects.

    • Do not interfere with the multi-display while it is moving.

    Tech Tips

    The multi-display can be operated using the multi-display switch.


    1. Open/Close Operation

      A003WL4E02

      1. Press the "OPEN/CLOSE" switch of the multi-display switch and check that the multi-display opens and closes properly.

        Tech Tips

        • When the multi-display is at tilt position 4, pressing the "TILT" switch causes the display to return to the initial position.

        • The tilt position of the multi-display at the time it was closed is stored in the display module board. The next time the multi-display opens, it automatically returns to the stored tilt position.

  3. REMOTE TOUCH INITIAL CHECK

    Note


    • Before performing the initial check, check that there are no foreign objects that will interfere with remote touch switch knob operation and that the knob is not stuck.

    • To avoid interruption of remote touch switch knob operation, do not touch the knob during the initial check.

    Tech Tips


    • The remote touch performs initialization of its knob position at the time the vehicle is started and turned off.

    • When remote touch switch knob position initialization fails, DTC B1581 will be stored.


    1. Move the remote touch switch knob to a position other than the center and turn the power switch to on (ACC).

    2. Check that the remote touch switch knob moves automatically to the center of the movable area.

      Tech Tips


      • Initialization of the remote touch switch knob position is complete when the knob moves to the center of the movable area.

      • If remote touch switch knob position initialization fails, remote touch switch knob operation and pointer movement on the screen will not match.

      • If the remote touch switch knob does not move to the center of the movable area within 10 seconds because of foreign objects or the knob being stuck, the remote touch will stop operating.

      • When the foreign object is removed or the remote touch switch knob is freed, and the knob position changes, the knob moves to the center of the movable area and completes its initialization.

      • The remote touch will repeatedly try to initialize itself until initialization has been completed, except when a built-in motor has a malfunction.

    3. Move the remote touch switch knob to a position other than the center and turn the power switch off.

    4. Check that the remote touch switch knob automatically moves to the center of the movable area.

      Tech Tips

    2. Switch Illumination Check and DTC Check


      1. A003V4HE01

        Check that the remote touch switch knob automatically moves to the center of the movable area and that the "MAP/VOICE" and "MENU" switch illumination turns on.

        Tech Tips


        • If the remote touch switch knob does not automatically move to the center of the movable area, DTC B1581 is stored.

        • When a DTCs are stored as a present DTC during self check, the "MAP/VOICE" and "MENU" switch illumination blinks at 0.5-second intervals. The illumination will continue to blink until the self check is completed.

        • The switch illumination stops blinking only when the factor that caused the remote touch switch knob malfunction (DTC B1581) disappears, allowing the knob to automatically move to the center of the movable area.

    3. A003V9HE01

      Remote Touch Switch Knob Position Recognition Check


      1. Move the remote touch switch knob up, down, right and left to check that the brightness of the "MAP/VOICE" and "MENU" switch illumination changes.

        Tech Tips


        • If the brightness changes according to remote touch switch knob operation, the knob position is being recognized normally.

        • The brightness of the switch illumination changes between 0 and 100% according to the coordinates of the remote touch switch knob.

        • The coordinates of the remote touch switch knob change between 0 and 255 for both the lateral and longitudinal axes.

        • When the coordinates of both the lateral and longitudinal axes of the remote touch switch knob are 0, the brightness of the switch illumination becomes 0% (the lights will be off), and when the coordinates of both axes of the knob are 255, the brightness of the switch illumination becomes 100% (the switch lights will be on at full brightness).

    4. Switch Operation Check


      1. With the remote touch switch knob in the lower left position, check that pressing each switch on the remote touch turns on the "MAP/VOICE" and "MENU" switch illumination at 100% brightness.

        Tech Tips
