Title: NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM: OPERATION CHECK (2008 LX570)

OPERATION CHECK

1. Check 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 paths 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 actual 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 actual position.	When the vehicle is driving on new roads not available on the map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.

(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 is driven 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°, 1080°, 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 engine switch is turned on (ACC) or on (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 starts to move.

(9) When the vehicle is driven 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.

HINT:

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.
