Self-Diagnosis FunctionNJEL0602DESCRIPTIONNJEL0602S01Diagnosis function consists of the self-diagnosis mode performed automatically and the confirmation/
adjustment mode operated manually.
Self-diagnosis mode checks connections between all units and performs individual unit diagnosis for all
units in system. Results are displayed on LCD display.
Check/adjustment mode is used to perform trouble diagnosis that require operation and judgment by an
operator (trouble that cannot be automatically judged by the system), to check/change the set value, and
to display the error record of the navigation system.

DIAGNOSIS NUMBER CHARTNJEL0603S03
Diagnosis No. Possible causes
Diagnosis 1 Control unit (AV and NAVI C/U) is malfunctioning.
Diagnosis 2 AV and NAVI C/U determines that no map DVD-ROM is inserted.
Diagnosis 3If “DVD-ROM is malfunctioning. Check disc.” is displayed:
1. Remove inserted map DVD-ROM and check that it is correct special DVD-ROM.
2. Check that there is no dirt, damage, or warping on removed DVD-ROM.
3. If above checks reveal nothing unusual, insert another map DVD-ROM withsame contents. Then check
whether same diagnosis result is obtained when “Self-diagnosis” is performed. If result is same, AV and NAVI
C/U is malfunctioning. If not same, map DVD-ROM should be replaced.
Diagnosis 4“DVD-ROM or DVD-ROM driver in C/U is malfunctioning. Follow maintenance procedures to diagnose.” is dis-
played: Perform check as described in Diagnosis 3.
Diagnosis 5Display power supply or ground line
AV communication line between Display and multifunction switch
Diagnosis 6 Audio unit power supply or ground line
Diagnosis 7 CD auto changer power supply and ground circuit, Communication line between CD auto changer and audio unit
Diagnosis 8GPS antenna system
1. Visually check for open circuit in GPS antenna coaxial cable.
2. Disconnect GPS antenna connector and check AV and NAVI C/U outputs approx. 5V. If there is no voltage,
AV and NAVI C/U is malfunctioning. If there is, replace GPS antenna. If connection is inoperative after per-
forming self-diagnosis again, AV and NAVI C/U is malfunctioning.

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
