Reading and Clearing Diagnostic Trouble Codes

NOTE: This is the only information provided by the manufacturer for Reading Diagnostic Trouble Codes for this system.

PRE-CHECK

1. USER TROUBLES UNDER NORMAL CONDITION OF THE NAVIGATION SYSTEM

a. Voice guidance is not performed even though the system is in normal condition when:
1. The destination is not set up.
2. The vehicle is not driving on the set route. (The remaining distance is not displayed at the lower left of the map screen that tells the current position of the vehicle.)
3. "Guidance in Other Modes" is not set up. (In this case no voice guidance is given except on the map screen.)

b. The vehicle icon turns around arbitrarily on the screen even when the system is in normal condition. If the ignition switch is turned to "ACC" or "ON" while the vehicle is turning around such as being on the turntable, the Navigation System memorizes the angle speed of that moment as the standard figure. To solve this problem, at the vehicle speed of 0 MPH (0 km/h), turn off the ignition switch and, then turn into "ACC" or "ON" again, and see whether any trouble occurs again.

2. INSPECTION OF THE LOCATION WITH TROUBLE OCCURRENCE
Examine whether the wrong display of the vehicle icon appears in a certain location or in several locations.

HINT: It is difficult to determine the accurate vehicle position when driving on a freeway, a looped road or a road which runs in parallel with another, and immediately after going a out of the parking area. In such cases the vehicle icon can be displayed off the real position of the vehicle.
