DRIVING TEST=NBEL0234S03During 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.
IRemove the GPS antenna connector from the display & NAVI
control unit. Drive the vehicle.
Before driving the vehicle, perform ªADJUST CURRENT
LOCATIONº (EL-411).
Test pattern 2
Test procedure in which map matching is not used.
IBefore driving the vehicle, perform ªADJUST CURRENT
LOCATIONº (EL-411). 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
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.
display>
,Perform test patterns 1 and 2.
ICompare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.

,Perform test patterns 1 and 2.
IMake 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.

Possible cause Drive condition Service procedure
AreaSlippery road surfaceOn 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 ªADJUST CUR-
RENT LOCATIONº (EL-411). If
necessary, perform ªSPEED
CALIBRATIONº (EL-409). Slanted areaHilly 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
dataMap 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 ªSPEED CALI-
BRATIONº (EL-409). After
removing the tire chains, sens-
ing accuracy may recover by
itself.

Possible cause Drive condition Service procedure
Opera-
tionDriving 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
ªSPEED CALIBRATIONº (EL-
409).
Rough or violent drivingWheel 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 ªADJUST CUR-
RENT LOCATIONº (EL-411).

tion pro-
ceduresPositional 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 ªADJUST CURRENT
LOCATIONº (EL-411) 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 ªADJUST CURRENT

Possible cause:
Ð: Vehicle running ---: IndicationDrive condition Service procedure
Loca-
tionParking 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 ªADJUST CURRENT LOCATIONº (EL-411).
NOTE:
IWhen 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.
IThe 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
IDuring 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
IVehicle 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
IThe map matching function requires verification of local data. To make the map matching function, some
distance needs to be driven.
IThe 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.
