DRIVING TEST
=NBEL0427S03
During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test pattern 1
Test method in which current position adjustment is not made
according to GPS data.
쐌
Remove the GPS antenna connector from the display & NAVI
control unit. Drive the vehicle.
Before driving the vehicle, perform “ADJUST CURRENT
LOCATION” (EL-545).
Test pattern 2
Test procedure in which map matching is not used.
쐌
Before driving the vehicle, perform “ADJUST CURRENT
LOCATION” (EL-545). With the ignition switch OFF and the
map CD-ROM removed from the display & NAVI control unit,
drive the vehicle. After driving the vehicle, reinstall the map
CD-ROM. Compare the saved driving tracks for the vehicle’s
current location with roads on the map.
Example
<The position marker consistently indicates the wrong position
when driving in the same area. Determine if this is the result of the
map matching function or the GPS function.>
,
Perform test pattern 1.
<To verify the accuracy of the road configuration shown on the
display>
,
Perform test patterns 1 and 2.
쐌
Compare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.
<To make distance calibration and adjustments>
,
Perform test patterns 1 and 2.
쐌
Make adjustments by driving the vehicle over a known course
(highway or other road where distances are clearly marked).
Calibrate the distance against the known distance. Use the
formula below.
Calibration value = Screen display distance/Actual distance

EXAMPLE OF CURRENT VEHICLE POSITION MARKER ERROR
=NBEL0428S02
The navigation system reads the vehicle distance and steering angle data. Because the vehicle is moving,
there will be an error in the current position indication. After the error appears, drive the vehicle for a short
distance. Stop the vehicle. If the position marker does not return to its original position, perform “ADJUST
CURRENT LOCATION” (EL-545).

Possible cause
Drive condition
Service procedure
Area
Slippery road surface
On wet, icy, or gravel road where
frequent wheel slippage occurs, dis-
tance calculations may be errone-
ous. The position marker may show
the vehicle to be in inaccurate posi-
tion.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform “ADJUST CUR-
RENT LOCATION” (EL-545). If
necessary, perform “SPEED
CALIBRATION” (EL-543).
Slanted area
Hilly areas where the road has
banked curves. When the vehicle
enters these banked curves, there
may be an error in steering angle
measurement. The position marker
may show the vehicle to be in inac-
curate position.
Map
data
Map display for a given road does not appear.
SEL699V
When the vehicle is driven on a
newly constructed road that does
not appear on the existing map.
Map marking and calibration are not
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position.
Subsequently, when the vehicle is
driven on a road which is available
as map data, the position marker
may still indicate an inaccurate posi-
tion.
The vehicle is driven on a road whose course
has been altered (usually to improve the road or
to eliminate some hazard).
SEL700V
When the map data shown on the
display and the actual conditions are
different. Map matching will not be
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position. If
the vehicle is driven on the indicated
road, further errors may occur.
Vehicle
Use of tire chains (Stormy weather)
Tire chains will affect distance sens-
ing. The position marker may indi-
cate inaccurate position.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform “SPEED CALI-
BRATION” (EL-543). After
removing the tire chains, sens-
ing accuracy may recover by
itself.
NAVIGATION SYSTEM
This Condition is Not Abnormal (Cont’d)
EL-560
Possible cause
Drive condition
Service procedure
Opera-
tion
Driving immediately after starting engine.
The gyro (angular velocity sensor)
needs about 15 seconds after the
engine is started to precisely sense
the angular velocity. Directional
sensing errors will occur if the
vehicle is moved immediately after
starting the engine. The position
marker may indicate inaccurate
position.
Wait a few moments between
starting the engine and actually
driving the vehicle.
Continuous driving for long distances (non-stop)
When the vehicle is driven continu-
ously without stopping over a long
distance, errors in directional sens-
ing may occur. The position marker
may indicate inaccurate position.
Stop the vehicle. Perform
“SPEED CALIBRATION” (EL-
543).
Rough or violent driving
Wheel spinning (peeling out) or simi-
lar rough driving techniques can
adversely affect sensing accuracy.
The position marker may indicate
inaccurate position.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform “ADJUST CUR-
RENT LOCATION” (EL-545).
Posi-
tional
calibra-
tion pro-
cedures
Positional calibration precision
SEL701V
If current vehicle location is roughly
set, the system may be unable to
locate the road that the vehicle is
traveling on. (This is especially true
in an area where there are many
roads.)
Perform “ADJUST CURRENT
LOCATION” (EL-545) within a
precision standard of 1 mm
(0.04 in) on the display.
Note: During calibration, use
the most detailed map pos-
sible.
Position calibration direction
SEL702V
When calibrating the position, check
the vehicle direction. If the vehicle
direction is not correct, subsequent
precision of current location will be
affected.
Perform “ADJUST CURRENT
LOCATION”, refer to EL-545.

Service procedure
Road
shapes
Y-intersection
SEL703V
In Y-intersections with a very
gradual change in course, a direc-
tional sensing may be inaccurate.
This may result in the position
marker giving the wrong road indica-
tion.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform “Store place”. If
required, also perform
“ADJUST CURRENT LOCA-
TION” (EL-545).
Spiral road
SEL704V
On loop bridges and similar struc-
tures which result in a large and
continuous turn, turning angle may
be sensed inaccurately. As a result,
the position marker may separate
from the route on the map.
Straight road
SEL705V
In long distance driving on a straight
road or road with very gradual
curves, map marking inaccuracies
may occur. In such cases, the posi-
tion marker may stray from the route
being traveled during subsequent
turns due to inaccurate distance cal-
culation.
Winding road
SEL706V
Directional sensing precision errors
may occur when traveling on wind-
ing roads. During map matching, the
position marker may stray to an
adjacent road having a similar
shape. Subsequent position marker
error may occur.
Grid-like road shape
SEL707V
Directional sensing and distance
sensing, precision errors may occur
because of many roads having a
similar shape in the immediate area.
During map matching, the position
marker may stray to an adjacent
road having a similar shape. Subse-
quent position marker error may
occur.
Parallel roads
SEL708V
When driving on a parallel road,
map matching errors may occur.
Subsequent position marker error
may also occur.

Service procedure
Loca-
tion
Parking lot or similar area
SEL709V
When the vehicle is driven in a park-
ing lot or similar area, such as in an
area not normally marked as a road
on map, during map matching, the
system may select nearby roads.
This error may continue after the
vehicle exits the parking area and
begins to run on ordinary roads.
Vehicle operation in a parking area
may involve frequent turns and up
and/or down operation. Directional
sensing errors may occur leading to
subsequent route and position mis-
takes.
Turntable
SEL710V
When the ignition switch is OFF (the
usual situation when the vehicle is
on a turntable), the navigation sys-
tem receives no data from the gyro
(angular velocity sensor). When the
turntable rotates, no directional
change is sensed. During subse-
quent vehicle operation, directional
and route errors may occur.
Position marker displays a completely different location
In circumstances such as those described below, GPS signal reception conditions may result in an erroneous
position of the position marker. Perform “ADJUST CURRENT LOCATION” (EL-545).
NOTE:
쐌
When GPS satellite signal reception conditions are poor, the position of position marker may be errone-
ous. If correction is not made immediately, the position marker error will be compounded and a completely
different location will be indicated. In an area where GPS satellite signal reception conditions are good,
the system can be returned to normal operation.
쐌
The vehicle is driven aboard a car ferry or is towed for some distance with the ignition switch OFF. Vehicle
movement is not sensed. Current location calculations do not occur and current location data does not
appear on the display screen. Use GPS to accurately determine actual vehicle position. The system can
be returned to normal operation when the GPS satellite signal reception conditions are good.
Position marker jumps
In circumstances such as those described below, the position marker may jump as a result of automatic cur-
rent location corrections made by the system.
During map matching
쐌
During map matching, the position marker may jump from one spot to another. In this case, it may be cor-
rected to a wrong road or to an area where no road exist.
GPS location correcting
쐌
Vehicle current location is sensed using the GPS data. Positional calibration is performed. The position
marker continues to be in the wrong position. It may jump about from one area of the screen to another.
In this case, it may be corrected to a wrong road or to an area where no road exist.
Position marker indicates that the vehicle is in the middle of an ocean or large river
The navigation system does not distinguish between land and water surfaces. In some cases, a position
marker error may cause the display to show the vehicle above a water surface.
Position of position marker varies when the vehicle is repeatedly operated on the same road
Driving lane and steering wheel movement results in a variety of different positions of the position mark when
traveling on the same road based on sensing results by the GPS antenna and gyro (angular velocity sensor).
Slow locational correction using map matching
쐌
The map matching function requires verification of local data. To make the map matching function, some
distance needs to be driven.
쐌
The map matching function may not provide accurate performance in an area where there are numerous
parallel roads. Until the system judges the road characteristics, an incorrect position may be shown.

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
쐌
he system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limitation
of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
쐌
The navigation system uses GPS data to determine vehicle location. GPS data is compared with other
locational sensing data during the map matching process. The system decides which data is more pre-
cise and uses that data.
쐌
When the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEW

display differ.
To prevent the display from becoming congested, alphanumeric information is abridged.

Vehicle position precision is bad.
The map surface precision display (GPS satellite marker) still remains gray.
[Refer to “The map surface precision display (GPS satellite marker) still remains gray” item (Symptoms)]
Vehicle speed and elapsed distance is calculated from the vehicle speed pulse. This pulse is dependent upon
tire size. If tire chains are used on the vehicle, accuracy will be affected (pulse rate will be too fast or too slow).
The same is true if the system installed to your vehicle is removed and installed on another vehicle.
[Drive the vehicle at a speed higher than 30 km/h (19 MPH) for approximately 30 minutes. Automatic read-
justment should occur. If it does not (remains too fast or too slow), distance calibration is required. Or, drive
the vehicle for a short distance. Perform “SPEED CALIBRATION” (EL-543). After removing the tire chains,
sensing accuracy may recover by itself.]
