Navigation System: Testing and Inspection
Pre-Check
PRE-CHECK
1. USER TROUBLES UNDER NORMAL CONDITION OF THE NAVIGATION SYSTEM
a. Voice guidance does not perform in the following situation even if the system is in normal condition.
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 or map 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 a 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 it to "ACC" or "ON" again to see whether any trouble occurs again.
2. INSPECTION OF THE LOCATION WITH TROUBLE OCCURRENCE
Check 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 out of the parking area. In such cases the vehicle icon can be displayed off the real position of the
vehicle.
3. OUTLINE OF AVC-LAN
Each unit of the navigation system connected with AVC-LAN (communication bus) transmits a signal of each switch. When +B or GND
shorts out in this AVC-LAN, the navigation system will not function normally as the communication is discontinued. In this AVC-LAN, the
radio receiver assy becomes the master of the communication, having resistance necessary for transmitting the signals.
