Operation Check

NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (for HDD): OPERATION CHECK

1. CHECK SYSTEM NORMAL CONDITION

(a) If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.





(b) The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor, speed sensor or display and navigation module display.





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

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





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





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





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





(8) 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) 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) When the tires are changed, the current vehicle position mark may deviate from the correct position.





HINT
* 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. REMOTE TOUCH INITIAL CHECK

NOTICE:
* 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.

HINT
* 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.

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

(b) Check that the remote touch switch knob moves automatically to the center of the movable area.

HINT
* 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.

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

(d) Check that the remote touch switch knob automatically moves to the center of the movable area.

HINT
* Initialization of the remote touch switch knob position is complete when the knob moves to the center of the movable area.
* If the remote touch switch knob does not move to the center of the movable area within 3 seconds because of foreign objects or the knob being stuck, the remote touch will stop operating. In this case, initialization of the knob position will not complete, but DTC B1581 will not be stored.

3. REMOTE TOUCH SELF CHECK

NOTICE:
* Before performing the remote touch self check, check that there are no foreign objects that would 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 unless instructed in the steps.

HINT
The following checks can be done via the self check:

* DTC check for the remote touch
* Switch illumination check
* Remote touch switch knob position recognition check
* Switch operation check
* Remote touch switch knob feedback force check

(a) Activate Self Check Mode





(1) Turn the power switch on (ACC) with the "DISP" switch and the down seesaw switch pressed to activate self check mode.

(b) Switch Illumination Check and DTC Check

(1) 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.





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

(c) 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.

HINT
* 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).

(d) 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.

HINT
If the "MAP/VOICE" and "MENU" switch illumination turn on when a switch is pressed, the switch being pressed is operating normally.

(e) Remote Touch Switch Knob Feedback Force Check





(1) Move the remote touch switch knob up, down, right and left to check that feedback force is generated.

HINT
The motors built into the remote touch generate feedback force according to the direction in which the remote touch switch knob is moved.

(2) Move the pointer on the screen by operating the remote touch switch knob and check that the feedback force of the knob changes according to the screen being displayed and the pointer position.

HINT
* Refer to Remote Touch Outline for further information on remote touch switch knob feedback force generated according to the screen being displayed and the pointer position System Description.
* When the feedback force of the remote touch switch knob changes according to the screen being displayed and the pointer position, it means that the remote touch is receiving feedback force request signals from the display and navigation module display.
* When the remote touch cannot receive feedback force request signals from the display and navigation module display, the remote touch generates feedback force according to the default feedback force image recorded in the remote touch (remote operation board).






(f) Finish Self Check Mode

(1) Turn the power switch off to finish self check mode.
