2 DRIVING TEST 2
Did any problem occur when the proper test in the following test patterns isperformed?
Test pattern
Driving test finds the difference between the symptoms monitored with andwithout 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
– by GPS>
Perform test pattern 1.
–
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.
–
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
YesorNo
Yes If adjustment is insufficient, perform adjustment again.
If any error is found in the map, please let us know.

ROUTE SEARCHINGNJEL0633S05
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) arenot
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.

Cause (condition) -:While driving ooo:Display Driving condition Remarks (correction, etc.)
Road con-
figurationY-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.
