Driving TestNJEL0632
1 DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT LOCATION COR-
RECTION”.
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 the EL-500, “Example of Symptoms Judged Not Abnormal” present after driving the
vehicle?
YesorNo
Yes Limit of the location detection capacity of the navigation system
No GO TO 2.
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
–
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.
Replace AV and NAVI control unit

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.
VEHICLE MARKNJEL0633S02
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
correctly.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 night-
time 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
adjustment function.Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in
accordance 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 signal cannot be received because some-
thing is placed on driver’s side instrument panel.Do not place anything on driver’s side
instrument panel.
GPS satellites are located badly. Wait until the location becomes better.
Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark)onthe
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
fitted or the system has been used on another
vehicle.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
CONFIRMATION/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.
