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.

Self-Diagnosis Mode (DCU)NKS003KF
OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “4” button, turn the volume control dial clock- wise or counterclockwise for 30 clicks or more. (When the self-
diagnosis mode is started, a short beep will be heard.)

Shifting from current screen to previous screen is performed
by pressing “BACK” button.
4. The initial trouble diagnosis screen will be shown, and items “Self Diagnosis (DCU)”, “Self Diagnosis (NAVI)”, “Confirmation/
Adjustment” and “CAN DIAG SUPPORT MONITOR” will
become selective.
5. Perform self-diagnosis by selecting the “Self Diagnosis (DCU)”.

Self-diagnosis screen is displayed, and then self-diagnosis
starts.

The bar graph visible below self-diagnosis screen displays
progress of the diagnosis.
6. When the self-diagnosis completes, optional part confirmation screen will be shown.

When connection of an optional part is judged error, a screen
to check if the optional part is actually fitted on the vehicle or
not will be shown. When fitted, select the switch of the part on
the screen and press “End”. Then the “SELF DIAGNOSIS”
screen will be shown.

When the optional part is connected normally, the switch for
the part will not appear on the screen.

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.
