CHECK ENVIRONMENT

Check if any metal object that intercepts radio waves or an object that emits radio waves (such as a portable
phone) is located near the GPS antenna. Check if the vehicle is shielded by a building.

●

System is normal.
The GPS antenna may not be able to receive radio waves from the GPS satellite if it is shielded
by metal object or an object emitting radio waves is placed near it.

Driving Test

NKS002GL

1. 

DRIVING TEST 1

1.

Scroll the map screen to display the area to make correction. Press “ENTER” and select “ADJUST CUR-
RENT LOCATION”.

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 

AV-82, "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

●

Does any malfunction occur when the proper test in the following test patterns is performed?

●

Test pattern
Driving test it to find 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 NAVI control unit. Accurately adjust the current
position and the direction, and 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 NAVI control
unit with the 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

–

<When the current-location mark skips at the same position, to determine, 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 1and 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 1and 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

Symptom

Cause

Remedy

Map screen and bird view ™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” 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 (19 MPH)] and 
the deviation will be automatically adjusted. 
If advancement or retards 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.
