DISPLAY DIAGNOSIS
●
When RGB signal error occurred in the RGB system, tone of the color bar will change as follows.
●
When the color of the screen looks unusual, refer to
AV-145, "Color of RGB Image is Not Proper (All
,
AV-146, "Color of RGB Image is Not Proper (All Screens Look Reddish)"
and
147, "Color of RGB Image is Not Proper (All Screens Look Yellowish)"
.
VEHICLE SIGNALS
●
A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set D/N mode to ON/OFF
of lighting switch (normal setting).
●
OFF: D (Day mode)
●
ON: N (Night mode)
Unless above setting, light signal (ON/OFF) may not be
accurately displayed.

HISTORY OF ERRORS
DIAGNOSIS BY HISTORY OF ERRORS
The “Self-diagnosis” results indicate whether an error occurred during 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-diag-
nosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past which can-
not 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
NAVI control 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 may 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, number 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 diagnose the item.

GPS substrate.
●
Navigation location detection performance
has deteriorated.
(Location correction using GPS is not per-
formed.)
●

●
Perform self-diagnosis.
●
When the NAVI control unit is judged normal by self-diagnosis,
the symptom may be intermittent, caused by strong radio inter-
ference.

ing oscillation circuit exceeded (or below) the specification
●
Navigation location detection performance
has deteriorated.
(Location correction using GPS is not per-
formed.)
●
GPS receiving status remains gray.
●
Perform self-diagnosis.
●
When the NAVI control unit is judged normal by self-diagnosis,
the symptom may be intermittent, caused by strong radio inter-
ference, or the control unit may have been subjected to exces-
sively high or low temperatures.
GPS ROM
malfunction
GPS RAM
malfunction
Contents of ROM (or RAM) in GPS substrate are malfunctioning.
●
Location detection accuracy of the navigation
system will deteriorate, depending on the error
area in the memory, because GPS cannot
make correct positioning.

formed.)

Adjusts turning angle output detected by the gyroscope.
Speed Calibration
●
During normal driving, distance error caused by tire wear and
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 Location
●
This mode is for initializing the current location.
