Example of Symptoms Judged Not MalfunctionNKS004BF
BASIC OPERATION
NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or becomes dis-
charged. If this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE ICON
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turns off.
Push and hold to turn on the display.
No voice guidance is available.
The volume is too high or too low.The volume is not set correctly, or it is turned off. Adjust the volume of voice guidance.
Volume guidance is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
No map is displayed on the screen.The map DVD-ROM is not inserted, or it is inserted
upside down.Insert the map DVD-ROM correctly.
A screen other than map screen is displayed. Push “MAP”.
The screen is too dim.
The movement is slow.The temperature in the interior of the vehicle is low.Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others.This condition is an inherent characteristic of liquid
crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while the
vehicle is driven.Park the vehicle in a safe location, and
then operate the navigation system.
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between Plan view and Bird-
view™.This is because the quantity of the displayed infor-
mation is reduced so that the screen does not
become too crowded. There is also a chance that
names of the roads or locations may be displayed
multiple times, and the names appearing on the
screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition switch
was turned off, for example, by a ferry or car trans-
porter.Drive the vehicle for a while on a road
where GPS can be received.
The position and direction of the vehicle may be
incorrect depending on the driving environments and
the levels of positioning accuracy of the navigation
system.This is not a malfunction. Drive the vehi-
cle for a while to automatically correct the
position and direction of the vehicle icon.
When the vehicle is travelling on a
new road, the vehicle icon is
located on another road nearby.Because the new road is not stored in the map data,
the system automatically places the vehicle ion on
the nearest road available. Updated road information will be included
in the next version of the map DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the head-
lights were turned on.Set the screen to the night screen mode
using when turning on the headlights.
The map does not scroll even
when the vehicle is moving.The current location map screen is not displayed. Push “MAP”.
The vehicle icon is not displayed. The current location map screen is not displayed. Push “MAP”.
The GPS indicator on the screen
remains gray.GPS signals cannot be received depending on the
vehicle location, such as in a parking garage, on a
road that has numerous tall buildings, etc.Drive on an open, straight road for a
while.
GPS signals cannot be received because objects
are placed on the rear parcel shelf.Remove the objects from the rear parcel
shelf.
A sufficient amount of GPS satellites are not avail-
able.Wait for the satellites to move locations
available for navigation system.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
VEHICLE MARK IS IN A RIVER OR SEA
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
VEHICLE MARK AUTOMATICALLY ROTATES
The system wrongly memorizes the rotating status as stopping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
WHEN DRIVING ON SAME ROAD, SOMETIMES VEHICLE MARK IS IN RIGHT PLACE AND
SOMETIMES IT IS WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP-MATCHING IS SLOW
The map matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.
Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be cor-
rected until some special feature is found.
ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION
The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the vehicle mark may not be
on the correct street, even when GPS location-correction is done.
The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.
GPS location correction may not be performed when the vehicle is stopped.
NAME OF CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF DISPLAY DIFFER FOR BIRDVIEW® AND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW
® Screen From the Flat Map Screen Are As Follows
The current place name displays names which are primarily in the direction of vehicle travel.
The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
Some thinning of the character data is done to prevent the display becoming to complex. In some cases
and in some locations, the display contents may differ.
The same place name, street name, etc. may be displayed multiple times.

CAN COMMUNICATIONPFP:23710
System DescriptionNKS003XV
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

ILLUMINATION
Revision: 2006 January2006 M35/M45
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil,
which, when energized, directs power
through IPDM E/R terminal 21
to combination meter terminal 13
to LDW switch (illumination) terminal 5 (with lane departure warning)
to VDC off switch (illumination) terminal 3
to trunk lid opener switch (illumination) terminal 3
