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 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 applicable to the

AV-108, "Example of Symptoms Judged No malfunction"

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 the GPS antenna connector (GT5) connected to the AV and NAVI control unit. Accurately
adjust the current position 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.

●

Replace AV and NAVI control unit.

NO

BASIC OPERATION

VEHICLE MARK

DESTINATION, PASSING POINTS, AND MENU ITEMS CANNOT BE SELECTED/SET

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 screen may
be inhibited by the automatic illumination adjust-
ment 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” switch to display the current
location.

Vehicle mark will not be shown.

Current location is not displayed.

Press “MAP” switch 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 (19MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by Confirmation/
Adjustment Mode mode of diagnosis func-
tion.

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.

Symptom

Cause

Remedy

Destination cannot be set.

Destination to be set is on an expressway.

Set the destination on an ordinary road.

Passing point is not searched
when re-searching the route.

The vehicle has already passed the passing point,
or the system judged so.

To include the passing points that have been
passed into the route again, set the route
again.
