OPERATION CHECK
CHECK NAVIGATION SYSTEM NORMAL CONDITION
(a) If the cause of a symptom is any of the following, the corresponding symptom is normal; it is not a malfunction.
| 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 hybrid control 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 internal memory, the system attempts to match it to another nearby road, causing the position mark to deviate. |
(b) The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor or navigation ECU.
(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 the 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) 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.
(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.
REMOTE TOUCH SELF CHECK
NOTICE:
- Before entering self-diagnostic mode, make sure there are no obstacles which may interfere with operation of the remote touch screen, and that the touch screen is not dirty.
- Do not touch the touch screen except when required.
- Since the remote touch screen may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the remote touch in self-diagnostic mode.
HINT:
The following checks can be done via the self check:
- DTC check for the remote touch
- Switch illumination check
- Touch screen operation position recognition condition check
- Switch operation check
- Vibration feedback generation condition check
(a) Activate Self Check Mode
| *a | "MAP" Switch |
| *b | "BACK" Switch |
| *c | "Sub-function" Switch |
(1) Set the light control switch to TAIL.
(2) The "MAP" switch, "BACK" switch and "Sub-function" switch pressed, turn the power switch on (ACC) to enter self-diagnostic mode.
NOTICE:
Self diagnostic mode will not start if any switches other than "MAP" switch, "BACK" switch and "Sub-function" switch are pressed.
(b) Switch Illumination Check and DTC Check
(1) Check that the switch illumination turns on.
.png)
| *a | Switch Illumination |
HINT:
When DTCs are stored as present DTCs during the self check, the switch illumination blinks at 0.5-second intervals. The illumination will continue to blink until the self check is completed.
(c) Touch screen operation position recognition condition check
.png)
| *a | Lateral Axis |
| *b | Longitudinal Axis |
(1) Operate the touch screen laterally and longitudinally and check that the brightness of the switch illumination changes.
HINT:
- If the brightness of the switch illumination changes according to the touch screen operation, the touch screen operation position is correctly recognized.
- The brightness of the switch illumination changes between 0% and 100% according to the touch screen position coordinates.
- The touch screen position coordinates change between 0 and 255 on the lateral axis and longitudinal axis.
- When the touch screen operation position coordinates are Lateral Axis: 0 and Longitudinal Axis: 0, the brightness of the switch illumination is 0% (off). When the coordinates are Lateral Axis: 255 and Longitudinal Axis: 255, the brightness of the switch illumination is 100% (illuminated).
(d) Switch Operation Check
(1) Check that the switch illumination turns on at 100% when each switch is pressed with the touch screen operated at the upper left position.
HINT:
If the switch illumination turns on at 100% brightness when a switch is pressed, the switch being pressed is operating normally.
(e) Vibration feedback generation condition check
(1) Operate the remote touch screen to move the pointer displayed on the multi-display assembly screen and check that the touch screen generates vibration feedback according to the display screen and pointer display position.
.png)
| *a | Default Feedback Force Image |
| *b | Button |
NOTICE:
On the multi-display assembly customize setting screen, when the remote touch screen vibration feedback reaction force setting is set to "NO VIBRATION", no vibration feedback is generated.
HINT:
- If the remote touch generates vibration feedback according to the display screen and pointer display position, the remote touch is correctly receiving the reaction force setting signal sent by the radio receiver assembly.
- If the remote touch cannot receive the reaction force setting signal sent by the radio receiver assembly, use the default feedback force image stored in the remote touch to generate vibration feedback on the touch screen.
(f) End Self-diagnostic Mode
(1) Wait 30 seconds without performing any operations or turn the power switch off to end self diagnostic mode.
