Special Note for Trouble DiagnosisNKS003KD
Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 1 5 2 , "
Example of Symptoms Possible No Malfunction" .
On Board Self-Diagnosis FunctionNKS003KE
DESCRIPTION

Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.

Self Diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the display.

Confirmation/Adjustment mode displays trouble diagnosis that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.
DIAGNOSIS ITEM
Mode Description
Self Diagnosis (DCU)

Display control unit diagnosis

Analyzes connection between the display control unit and each unit, and
operation of each unit.
Self Diagnosis (NAVI)

NAVI control unit diagnosis (DVD-ROM drive will not be diagnosed
when no DVD-ROM is in it.).

Analyzes connection between the NAVI control unit and the GPS
antenna.
Confirmation/
Adjustment Display Diagnosis
Color tone and shading of the display control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to display control unit can be performed
for Vehicle Speed, IGN, Reverse and Light.
Auto Climate Control Refer to ATC-52, "
Self-diagnosis Function" .
Navigation Display Diagnosis
Color tone and shading of the NAVI control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to NAVI control unit can be performed
for Vehicle speed, Lights, Ignition and Reverse.
Navigation Steering
Angle
Adjustment This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring
function will automatically compensate for minute decreases in wheel and
tire diameter caused by tire wear or low-pressure. Speed Calibration can
immediately restore system accuracy in cases such as when distance cal-
ibration is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the num-
ber of times each has occurred. Time and location when/where the errors
occurred are also displayed.
Delete Unit Connection Log Erase the connection history of unit and error history.
CAN DIAG SUPPOPT MONITOR The transmitting/receiving of CAN communication can be monitored.

7. On the diagnosis results screen, each unit name and connection
line will be colored according to the diagnosis result, as follows.
NOTE:

Satellite = Satellite radio tuner

DCU = Display control unit

Multifunction switch = A/C and AV switch

Navigation = NAVI control unit

GPS = GPS antenna

If multiple malfunctions occur at the same time for a single unit, the screen switch colors are determined
according to the following order of priority: red > yellow > gray.
8. Select a switch on the diagnosis results screen, and comments for the diagnosis results will be shown.
SELF-DIAGNOSIS RESULT
Quick Reference Table
1. Select the applicable diagnosis number in the quick reference table of diagnosis result.
2. Confirm the possible malfunction with the diagnosis table, and then perform inspection.
3. Turn ignition switch OFF and perform self-diagnosis again.

When A/C and AV switch has a malfunction, the self-diagnosis cannot be started. Refer to AV- 1 3 7 , "A/C
and AV Switch Self-Diagnosis Function" .

When display has a malfunction, the self-diagnosis cannot be started. Refer to AV-141, "All Images Are
Not Displayed" .
Green : No malfunctioning.
Gray : Cannot be judged by self-diagnosis results.
Red : Unit is malfunctioning.

DISPLAY DIAGNOSIS
Color tone and shading of the display control unit-generated image can be checked by the display of a color
bar and a gray scale.

If RGB signal is malfunctioning, the tint of the color bar display is as follows.
VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal and
the signals recognized by the display control unit.
NOTE:
In case of confirming light signal, set the following 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. R (red) signal error : Light blue (Cyan) tint
G (green) signal error : Purple (Magenta) tint
B (blue) signal error : Yellow tint

Vehicle Signals
A comparison check can be made of each actual vehicle signal and
the signals recognized by the NAVI control unit.
Navigation
Steering Angle Adjustment
The steering angle output value detected by the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed, etc., perform this procedure.

Error History
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting “Self Diag-
nosis” until self-diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “Self Diagnosis”, and if an error does not occur until self-
diagnosis results is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with “Error History” for the past error that is not available
with self-diagnosis.
“Error History” 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 vehicle mark at the time when the error
occurred. If the vehicle mark has deviated from the correct position, then the place of the error occurrence
may not be located correctly.

When the ignition switch is turned ON if the error is detected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON the next time, the counter does not decrease.

The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log”
switch.

Diagnosis by Error History

When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunc-
tion, turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or
delete “Error History”). Check “Error History” again after the malfunction was reproduced, and then per-
form diagnosis focusing on the item of which number of time increased.

DVD-ROM error history may be restored because DVD-ROM cannot be temporarily read. (Driving on
rough road etc.) Then, erase the error history. (This is not a malfunction.) Perform service in “Action to
take” if error history are repeatedly indicated again.
Error item Possible cause Action to take
GPS Antenna Error GPS antenna connection malfunction
is detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, GO TO 3. If any error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.)
3. Check if GPS antenna feeder line is snapped or pinched.
4. If the results from the above checkup show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
5. If self-diagnosis results still show any malfunction, replace NAVI control unit.
FLASH-ROM Error Of Control Unit
NAVI control unit malfunction is
detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, replace NAVI con- trol unit. Refer to AV-155, "
Removal
and Installation of NAVI Control Unit" .
If any error is not found, delete the error
history and end the diagnosis. (This is
not a malfunction.)
Connection Of Gyro
GPS Communication Error GPS malfunction is detected. If the symptoms such as the GPS receipt
malfunction occur, intermittent malfunc-
tion caused by strong radio interference
may be detected.
If the malfunction always occurs, replace
NAVI control unit.
GPS ROM Error
GPS RAM Error
GPS RTC Error
DVD-ROM Mechanism not Detected

Malfunction is detected on DVD-
ROM drive pickup lens in NAVI con-
trol unit.

There is dirt and damage on the
DVD-ROM. 1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any malfunction, replace NAVI control unit.
