for 3 seconds or more. Then, when these switches are released,
the buzzer sounds, all indicators of multifunction switch turned

Multi AV System Diagnosis FunctionsNKS0048U
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 DiagnosisNKS0048V
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.
