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.
SELF-DIAGNOSIS ITEMNJEL0602S02
Mode Diagnosis content
Self-diagnosisControl unit diagnosis (DVD-ROM drive will not be diagnosed when no
map DVD-ROM is in it.)
Performs diagnosis of connections between C/U and GPS antenna and
between C/U and all units.
Confirmation/
adjustmentDisplayColor tone and shading of the screen can be checked by the display of a
color bar and a gray scale.
Vehicle signalsThe following signals can be diagnosed: vehicle speed, parking brake,
light, IGN (IGN SW), and reverse.
History of ErrorsDisplays the navigation system-related problems that occurred in the past
and the number of their occurrence. When a trouble symptom is selected,
the time and place of the latest occurrence will be shown.
Auto Climate ControlAll A/C screen displays on LCD monitor and the A/C SW indicator lamp
are illuminated.
NavigationDisplay Longitude &
LatitudeDisplay the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.
Angle adjustmentCorrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
Distance adjustmentCorrects difference between the current-location mark on the display and
actual position of the vehicle.

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.
