Driving TestAKS007KG
1. DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT LOCATION CORRECTION”.
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 func-
tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.
4. Are symptoms malfunctioning to the AV- 1 7 1 , "
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.
NO >> GO TO 2.
2. DRIVING TEST 2
Did any malfunction 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 GPS antenna connector (GT5) connected to the NAVI control unit. Accurately adjust the cur-
rent location and the direction, and then drive the vehicle.
–Test pattern 2: Test method with no map-matching
Accurately adjust the current location and the direction. Eject the map DVD-ROM from the NAVI control
unit with ignition switch turned to OFF, and 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 and 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 and 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.

Replace NAVI control unit.
NO >> Limit of the location detection capacity of the navigation system.

Revision: 2005 July 2005 FX
Place In 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 traveling about 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction.
Turn ta ble
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
easily returned to after rotating the vehicle
on a turn table 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 traveling 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
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
correct 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 is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)
Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)
