Special Note for Trouble Diagnosis

NKS002Q8

Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to

AV-197, "Example of Symptoms Possible No Malfunction"

.

On Board Self-Diagnosis Function

NKS0023O

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-47, "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.
