DIAGNOSIS SYSTEM

DIAGNOSIS SYSTEM

PFP:00000

Multifunction Switch Self-Diagnosis Function

NKS0048T

It can check each switch ON/OFF (continuity) operation of centralized switches.

SELF-DIAGNOSIS MODE

●

Turn the ignition switch from OFF position to ACC position.
Within 10 seconds, press and hold BACK switch and 

 switch

for 3 seconds or more. Then, when these switches are released,
the buzzer sounds, all indicators of multifunction switch turned
on, and self-diagnosis mode is started.

●

When each switch is pressed, the switch continuity can be
checked by sounding the buzzer.

CAUTION:

The hazard switch cannot be checked.

FINISHING SELF-DIAGNOSIS MODE

●

When the ignition switch is turned ON, self-diagnosis mode is canceled.

Multi AV System Diagnosis Functions

NKS0048U

●

There are 2 diagnosis functions (On board diagnosis and diagnosis using CONSULT-II). It is necessary to
use them properly according to the condition. If the on board diagnosis starts, perform diagnosis with on
board diagnosis. If the on board diagnosis does not start (because the display is not displayed, the multi-
function switch operation is not activated, etc.), perform diagnosis using CONSULT-II.

●

At on board diagnosis, the AV (NAVI) control unit diagnosis function starts when multifunction switch oper-
ation and the AV (NAVI) control unit performs the diagnosis for each unit of system. Then, it displays the
results on the display.

●

At diagnosis using CONSULT-II, the AV (NAVI) control unit diagnosis function starts when the CAN com-
munication and the AV (NAVI) control unit perform the diagnosis for each unit of system.

On Board Diagnosis

NKS0048V

DESCRIPTION

●

It has Self-Diagnosis mode for conducting trouble diagnosis automatically and a Confirmation/Adjustment
mode for operating manually.

●

Self-diagnosis mode diagnoses AV (NAVI) control unit and communication of each unit composing sys-
tem, and displays self-diagnosis results. NAVI control unit diagnoses communication with GPS antenna
simultaneously.

●

Confirmation/Adjustment mode is used to monitor the vehicle signals requiring operation and judgement
by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/
change/adjustment of setting value, the error history of system, and the communication condition of sys-
tem.
