CHECK NAVIGATION SYSTEM NORMAL CONDITION
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 multi-media module 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 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 SD card (disc player disc), the system attempts to match it to another nearby road, causing the position mark to deviate. |
Expected arrival time is earlier than current time, or time different from expected arrival time is displayed. | If a destination is set to a point where a different time zone is used, the system displays an expected arrival time corresponding to the time zone of the destination. If a location on the sea is set as the destination, the system may display an expected arrival time corresponding to the time zone setting of the vehicle. Check which communication is not used for displaying traffic information. |
The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor or multi-media module receiver assembly.
The current position mark may be displayed on a nearby parallel road.
Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.
When the vehicle turns right or left at an intersection, the current vehicle position mark may be displayed on a nearby parallel road.
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.
When the vehicle travels on a steep hill, the current vehicle position mark may deviate from the correct position.
When the vehicle makes a continuous turn (e.g. 360, 720, 1080 degrees), the current vehicle position mark may deviate from the correct position.
When the vehicle moves erratically, such as constant lane changes, the current vehicle position mark may deviate from the correct position.
When the engine switch is turned on (ACC) or (IG) and the vehicle is turned 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.
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.
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.
REMOTE TOUCH SELF CHECK
Note
Before performing the remote touch self check, check that there is no foreign matter that may 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.
Tech Tips
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
Activate Self Check Mode
*a | Down Seesaw Switch |
*b | Switch Knob |
Turn the engine switch on (ACC) with the switch knob and down seesaw switch pressed to activate self check mode.
Switch Illumination Check and DTC Check
*a | Switch Illumination |
*b | Switch Knob |
Check that the remote touch switch knob automatically moves to the center of the movable area and that the "MENU" and home switch illumination blinks.
Tech Tips
When DTCs are stored as present DTCs during the self check, the "MENU" and home 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 disappears, allowing the knob to automatically move to the center of the movable area.
Remote Touch Switch Knob Position Recognition Check
*a | Switch Knob |
*b | Longitudinal Axis |
*c | Lateral Axis |
Move the remote touch switch knob up, down, right and left to check that the brightness of the "MENU" and home 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 switch 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).
Switch Operation Check
With the remote touch switch knob in the lower left position, check that pressing each switch on the remote touch turns on the "MENU" and home switch illumination at 100% brightness.
Tech Tips
If the "MENU" and home switch illumination turn on at 100% brightness when a switch is pressed, the switch being pressed is operating normally.
Remote Touch Switch Knob Feedback Force Check
*a | Switch Knob |
*b | Movement Direction |
*c | Feedback Force |
Move the remote touch switch knob up, down, right and left to check that feedback force is generated.
Tech Tips
The motors built into the remote touch generate feedback force according to the direction in which the remote touch switch knob is moved.
*a | Default Feedback Force Image |
*b | Frame Area |
*c | Icon Area |
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.
Tech Tips
Refer to Remote Touch Outline in System Description for further information on the remote touch switch knob feedback force generated according to the screen being displayed and the pointer position Click here.
When the feedback force of the remote touch switch knob changes according to the screen being displayed and the pointer position, the remote touch is receiving feedback force request signals from the multi-media module receiver assembly.
When the remote touch cannot receive feedback force request signals from the multi-media module receiver assembly, the remote touch generates feedback force according to the default feedback force image recorded in the remote touch (remote operation board).
