DRIVING TEST

NLEL0687S26

DRIVING TEST 1

1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT LOCATION COR-

RECTION”.

2. Correct direction of the vehicle mark.
3. Perform the distance correction of the CONFIRMATION/ADJUSTMENT mode.

NOTE:
Normally, adjustment is not necessary because this system has automatic distance correction function. However, when
a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be made.

4. Are symptoms applicable to the EL-450, “Example of Symptoms Judged Not Malfunction” present after driving the

vehicle?

Yes or No

Yes

Limit of the location detection capacity of the navigation system

GO TO 2.

DRIVING TEST 2

Did any problem occur when the proper test in the following test patterns is performed?

Test pattern
Driving test finds the difference between the symptoms monitored with and without each sensor.

–

Test pattern 1: Test method with no GPS location correction
Disconnect the GPS antenna connector connected to the AV and NAVI control unit. Accurately adjust the current posi-
tion and the direction, then drive the vehicle.

–

Test pattern 2: Test method with no map-matching
Accurately adjust the current position and the direction. Eject the map DVD-ROM from the AV and NAVI control unit
with the ignition switch turned to OFF, then drive the vehicle. After driving, insert the map DVD-ROM back in the unit,
display the track of the vehicle on the map screen and compare it with the actual road configuration.

Sample tests

–

<To determine if the current-location mark skips at the same position, if so, whether it is caused by map-matching or
by GPS>
Perform test pattern 1.

–

<To determine if the pattern of streets displayed is correct or not>
Perform test pattern 1 & 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate tracking,
plotting shall be made every several hundred meters.

–

<When the distance is adjusted accurately>
Perform test pattern 1 & 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate the rate of
change (increased/decreased) of the distance by comparing with the actual distance.
Correction = A/B
A: Distance shown on the screen
B: Actual distance

Yes or No

Yes

If adjustment is insufficient, perform adjustment again.

If any error is found in the map, please let us know.

ROUTE SEARCHING

NLEL0634S05

Symptom

Cause

Remedy

No route is shown.

No road to be searched is found around the
destination.

Find wider road (orange road or wider)
nearby and reset the destination and pass-
ing points onto it. Take care of the traveling
direction when there are separate up and
down roads.

Starting point and the destination are too close.

Set the destination at more distant point.

Conditional traffic regulation (day of the week/
time of the day) is set at the area around the
current position or the destination.

Turn the time-regulating search conditions
OFF. Turn “Avoid regulation time” in the
search conditions OFF.

Indicated route is intermittent.

In some areas, highways (gray routes) are not
used for the search Therefore, the route to the
current position or the passing points may be
intermittent.

System is not malfunction.

When the vehicle has passed the
recommended route, it is deleted
from the screen.

A recommended route is controlled by each
section. When the vehicle has passed the pass-
ing point 1, then the map data from the starting
point up to the passing point 1 will be deleted.
(The data may remain undeleted in some area.)

System is not malfunction.

Detouring route is recommended.

In some areas, highways (gray routes) are not
used for the search. Therefore, detour route
may be recommended.

Set the route closer to the basic route (gray
route).

A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the
area around the starting point or the destina-
tion.

Slightly move the starting point or the
destination, or set the passing point on the
route of your choice.

In the area where highways (gray routes) are
used for the search, left turn has priority around
the current position and the destination (pass-
ing points). For this reason, the recommended
route may be detouring.

System is not malfunction.

Landmarks on the map do not
match the actual ones.

This can happen due to omission or error in the
map data.

As a rule, an updated map DVD-ROM will
be released once a year. Wait until the lat-
est map has become available.

Recommended route is far from
the starting point, passing points,
and destination.

Starting point, passing points, and destination
of the route guide were set far from the desired
points because route searching data around
these area were not stored.

Reset the destination onto the road nearby.
If this road is one of the highways (gray
routes), an ordinary road nearby may be
displayed as the recommended route.

EXAMPLES OF CURRENT-LOCATION MARK DISPLACEMENT

=NLEL0634S06

Vehicle’s travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle

is driven in the following manner, an error will occur in the vehicle’s current location display. If correct location
has not been restored after driving the vehicle for a while, perform location correction.

Remarks (correction, etc.)

Road con-
figuration

Y-intersections

ELK0192D

At a Y intersection or similar gradual
division of roads, error the direction of
travel deduced by the sensor may
result in the current-location mark
appearing on the wrong road.

If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location
correction and, if necessary,
direction correction.

Spiral roads

ELK0193D

When driving on a large, continuous
spiral road (such as loop bridge), turn-
ing angle error is accumulated and the
vehicle mark may deviate from the
correct location.

Straight roads

ELK0194D

When driving on a long, straight road
and slow curve without stopping, map-
matching does not work effectively
enough and distance errors may accu-
mulate. As a result, the vehicle mark
may deviate from the correct location
when the vehicle turned at a corner.

Zigzag roads

ELK0195D

When driving on a zigzag road, the
map may be matched to other roads in
the similar direction nearby at every
turn, and the vehicle mark may deviate
from the correct location.

Roads laid out in a grid pattern

ELK0196D

When driving at where roads are laid
out in a grid pattern, where many
roads are running in the similar direc-
tion nearby, the map may be matched
to them by mistake and the vehicle
mark may deviate from the correct
location.

Parallel roads

ELK0197D

When two roads are running in parallel
(such as highway and sideway), the
map may be matched to the other
road by mistake and the vehicle mark
may deviate from the correct location.

Place

In a parking lot

SEL709V

When driving in a parking lot, or other
location 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 deviated from
the correct location.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, 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 location
correction and, if necessary,
direction correction.

Turn table

SEL710V

When the ignition switch is OFF, the
navigation system cannot get the sig-
nal from the gyroscope (angular speed
sensor). Therefore, the displayed
direction may be wrong and the cor-
rect road may not be easily returned to
after rotating the vehicle on a turn
table with the ignition switch 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 cases 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

SEL699V

When driving on new roads or other
roads not displayed on the map
screen, map matching does not func-
tion 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)

ELK0201D

If the road pattern stored in the map
data and the actual road pattern are
different, map matching does not func-
tion correctly and matches the location
to a nearby road. The vehicle mark
may deviate from the correct road.

Vehicle

Use of tire chains

When tire chains are used, the mile-
age is not correctly detected, and the
vehicle mark may deviate from the
correct road.

Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)

Precautions
for driving

Just after the engine is started

If the vehicle is driven off 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 driv-
ing after starting the engine.

Continuous driving without stopping

When driving long distances without
stopping, 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 to
perform correct detection, and may
cause the vehicle mark to deviate from
the correct road.

If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location
correction and, if necessary,
direction correction.

How to cor-
rect location

Position correction accuracy

SEL699V

If the accuracy of location settings is
poor, accuracy may be reduced when
the correct road cannot be found, par-
ticularly in places where there are
many roads.

Enter in the road displayed on
the screen with an accuracy of
approx. 1 MM.
NOTE:
Whenever possible, use detailed
map for the correction.

Direction when location is corrected

SEL702V

If the accuracy of location settings dur-
ing correction is poor, accuracy may
be reduced afterwards.

Perform direction correction.

THE CURRENT POSITION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG.

NLEL0634S07

In the following cases, the current-location 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 current-location 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

−

Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the pre-
cise location can be detected with GPS, the location will be corrected.

THE CURRENT POSITION MARK JUMPS.

NLEL0634S08

In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.

When map matching has been done

−

If the current location and the current-location mark are different when map matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.

When GPS location correction has been done

−

If the current location and the current-location mark are different when the location is corrected using GPS

NAVIGATION SYSTEM

EL-456

measurements, the current-location mark may seem to jump. At this time, the location may be “corrected”
to a location which is not on a road.

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA.

NLEL0634S09

The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.

WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT-LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE.

NLEL0634S10

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.

NLEL0634S11

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 corrected
until some special feature is found.

ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.

NLEL0634S12

The GPS accuracy has an error of about 10 m (30 ft). In some cases the current-location 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.

THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.

NLEL0634S13

The current place name may not be displayed if there are no place names displayed on the map screen.

CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW

AND THE (FLAT) MAP

SCREEN.

NLEL0634S14

Difference of the BIRDVIEW

Screen From the Flat Map Screen Are as Follows.

NLEL0634S1401

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.

System Description

NLEL0690

CAN (Controller Area Network) is a serial communication line for
real time application. It is an on-vehicle multiplex communication
line with high data communication speed and excellent error detec-
tion ability. Many electronic 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.
