Symptom
Cause Remedy
Map screen and BIRDVIEW™
Name of the place vary with the
screen. Some thinning of the character data is done to pre-
vent 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 not
be displayed every time on account of the data
processing. System is not malfunctioning.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function. Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed.
Press “MAP” button to display the current lo-
cation.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current lo-
cation.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el. Do not place anything on top of the meter dis-
play (instrument panel).
GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov- ing the vehicle.
Vehicle location accuracy is low. Accuracy indicator (GPS sate llite mark) on the
map screen stays gray. Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.) As a rule, an updated map DVD–ROM will be
released once a year.
Symptom
Cause Remedy
Destination cannot be set. Destination to be set is on an expressway. Set the destination on an ordinary road.
Passing point is not searched
when re-searching the route. The vehicle has already passed the passing point,
or the system judged so. To include the passing points that have been
passed into the route again, set the route
again.
Route information will not be dis-
played. Route searching has not been done.
Set the destination and perform route
searching.
Vehicle mark is not on the recommended route. Drive on the recommended route.
Route guide is turned OFF. Turn route guide ON.
Route information is not available on the dark pink
route. System is not malfunctioning.
After the route searching, no guide
sign will appear as the vehicle
goes near the entrance/exit to the
toll road. Vehicle mark is not on the recommended route.
(On the display, only guide signs related to the rec-
ommended route will be shown.)
Drive on the recommended route.

NORMAL OPERATING CONDITION
PlaceIn a parking lot
When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
Turntable
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be eas-
ily returned to after rotating the vehicle on a
turntable with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
travelling on banked roads, or in other cas-
es where the vehicle turns when tilted, an
error in the turning angle will occur, and the
vehicle mark may deviate from the road.
Map data Road not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair) If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the cor-
rect road.
Vehicle Use of tire chains When tire chains are used, the mileage is
not correctly detected, and the vehicle mark
may deviate from the correct road.Drive the vehicle for a while. If
the distance still deviates, ad-
just it by using the distance ad-
justment function. (If the tire
chain is removed, recover the
original value.)

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 directions
in the surrounding area, no matching determination ma y be made. The location may not be corrected until
some special feature is found.
Name of Road is Not Displayed
The current road name may not be displayed if there are no road 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 too complex. In some cases
and in some locations, the display contents may differ.
• The same place name, street name, et c. may be displayed multiple times.
Vehicle Mark Shows a Position Which is Completely Wrong
In the following cases, the vehicle mark may appear on completely different position in the map depending on
the GPS satellite signal receiving conditions. In this case, perform location correction and direction correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle mark becomes out of place, it may
move to a completely different location and not come back if location correction is not done. The position will
be corrected if the GPS signal can be received.
• When the vehicle has traveled by ferry, or when the vehicle has been being towed
Precautions
for driving Just after the engine is started
If the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location. Wait for a short while before
driving after starting the engine.
Continuous driving without stopping When driving long distances without stop- ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road. Stop and adjust the orientation.
Abusive driving Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct detec-
tion, and may cause the vehicle mark to de-
viate from the correct road. If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
How to cor-
rect location Position correction accuracy
If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads. Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the correc-
tion.
Direction when location is corrected
If the accuracy of location settings during
correction is poor, accuracy may be re-
duced afterwards. Perform direction correction.

- The voltage waveform of INPUT corresponding to the
formed circuit changes according to the operation of
the transistor on OUTPUT side if any (1 or more) switches are ON.
- It reads this change of the voltage as the status signal of the combination switch.
Operation Example
In the following operation example, the combination of t he status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TURN RH switch) is turned ON
 The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON.
 BCM detects the combination switch status signal “1E” when the signal of OUTPUT 5 is input to INPUT 1.
 BCM judges that the TURN RH switch is ON when the signal “1E” is detected.
Example 2: When some switches (turn RH s witch, front wiper LO switch) are turned ON
