SYSTEM NORMAL CONDITION CHECK

1. CHECK NORMAL CONDITION
(a) If the symptom is applicable to any of the following, it is the intended behavior, not a malfunction.






(b) The following symptoms are not a malfunction, but are caused by errors inherent in the GPS, gyro sensor, speed sensor, and 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 running, 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 runs on a steep hill, the current vehicle position mark may deviate from the correct position.




(6) When the vehicle makes a continuous turn of 360°, 720°, 1,080°, etc., 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 while parking, the current vehicle position mark may not point in the correct direction. The same will occur when the vehicle comes out of parking.




(9) When the vehicle runs 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 a tire is changed, the current vehicle position mark may deviate from the correct position.
- The diameter of the tire may change, causing a speed sensor error.
- Performing the "tire change" in calibration mode will allow the system to correct the current vehicle position faster.
