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
– matching or by GPS>
Perform test pattern 1.
–;
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.
–;
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.

Example of Symptoms Judged Not MalfunctionAKS007KH
BASIC OPERATION
VEHICLE MARK
Symptom Cause Remedy
No image is shown. Display brightness adjustment is set fully to DARK side. Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle
is driving on a dark pink route. System is not malfunction.
Screen is too dark.
Motion of the image is too slow. Temperature inside the vehicle is low. Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display. System is not malfunction.
Symptom Cause Remedy
Map screen and BIRDVIEW™
Name of the place vary with the
screen. 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 not
be displayed every time on account of the data
processing. System is not malfunction.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screens
may be inhibited by the automatic illumination
adjustment function. Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed. Press “MAP” button to display the current
location.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current location.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the
vehicle is in or behind a building. Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the display. Do not place anything in the center on top of
the display.
GPS satellites are located badly. Wait until the location becomes better.
Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark) on the map screen stays gray. Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.) As a rule, an updated map DVD-ROM will be
released once a year.
