5. When “CONFIRMATION/ADJUSTMENT” is selected on the
initial trouble diagnosis screen, the operation will enter the
CONFIRMATION/ADJUSTMENT mode. In this mode, check
and adjustment of each item will become possible.
6. Select each switch on “CONFIRMATION/ADJUSTMENT”
screen to display the relevant diagnosis screen.

tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving
with tire chain fitted on tires.
Initialize LocationNJEL0604S0404Description
Location data for GPS in the Center control unit is initialized in
Europe by this mode. Then it is possible for Center control unit
to receive GPS signals for short time.

NOTE:
To continue GPS initialized operation, operate as follows back
to “Map” screen.
− Push “BACK” button twice.
− Push “MAP” button.
After above operation, GPS indicator changes to green color
within half a minute, unless improper GPS located condition.
This operation should be performed in outside field.
HISTORY OF ERRORSNJEL0604S05
SKIA1518E
DIAGNOSIS BY HISTORY OF ERRORSNJEL0604S06The “Self-diagnosis” results indicate whether an error occurred dur-
ing the period from when the ignition switch is turned to ON until
“Self-diagnosis” is completed.
If an error occurred before the ignition switch was turned to ON and
does not occur again until the “Self-diagnosis” is completed, the
diagnosis result will be judged normal. Therefore, those errors in
the past, which cannot be found by the “Self-diagnosis,” must be
found by diagnosing the “History of Errors”.
The History of Errors displays the time and place of the most recent
occurrence of that error. However, take note of the following points.
Correct time of the error occurrence may not be displayed
when the GPS antenna substrate within the AV and NAVI con-
trol unit has malfunctioned.
Place of the error occurrence is represented by the position of
the current-location mark at the time when the error occurred.
If the current-location mark has deviated from the correct
position, then the place of the error occurrence max be located
correctly.
The maximum number of occurrences which can be stored is
50. For the 51st and later occurrences, the displayed number
remains 50.
When a reproducible malfunction occurred but its cause cannot be
identified because several errors are present, record the item, num-
ber and place (longitude/latitude) of error occurrence (or delete the

History of Errors), then turn the ignition switch from OFF to ON to
reproduce the malfunction. Check the History of Errors to find the
items which show an increased number of occurrences, and diag-
nose the item.

malfunctionContents of ROM (or RAM) in GPS substrate are malfunctioning.Location detection accuracy of the navigation
system will deteriorate, depending on the
failed area in the memory, because GPS
cannot make correct positioning.
(Location correction using GPS is not per-

When the AV and NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused by strong
radio interference.
GPS RTC
malfunctionClock IC in GPS substrate is malfunctioning.Correct time may not be displayed.
After the power is turned on, the system
always takes some time until GPS position-
ing becomes possible. (The GPS receiver
starts positioning without re-collecting the
whole satellite information when it judged the
data stored in the receiver is correct.)
Correct time of error occurrence may not be
stored in the “History of Errors”. Perform the self-diagnosis.
When the AV and NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused by strong
