Multifunction Switch Self-Diagnosis FunctionNKS004AV
It can check each switch ON/OFF (continuity) operation of multifunction switch.
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 FunctionsNKS004AW
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 performs the diagnosis for each unit of system.
On Board DiagnosisNKS004AX
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.

NAVIGATION
Steering Angle Adjustment
The steering angle output value detected with 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
The diagnostic results of “Self-diagnosis” determine if any malfunction occurred between selecting “Self-diag-
nosis” and displaying “Self-diagnostic Results”.
If an error occurred before the ignition switch was turned ON and does not occur again until “Self-diagnosis” is
completed, the trouble diagnosis result will be judged normal. Therefore, errors in the past which cannot be
found by “Self-diagnosis”, must be found by checking the “Error record”.
The error history shows the error occurrence frequency in past. The frequency of occurrence is displayed by 2
types: the count down type and the count up type. Select either type according to the error item.
In “Error History” of models with NAVI, time and place that the selected error last occurred are displayed. Be
careful about the following.
If there is a malfunction with the GPS antenna circuit board in the NAVI control unit, the correct date of
occurrence may not be able to be displayed.
Place of the error occurrence is represented by the position of the current location mark at the time an
error occurred. If current location mark has deviated from the correct position, then the place of the error
occurrence cannot be located correctly.

Count Down Type
When the error is detected, set the counter to 40. If the system is normal when turning the ignition switch
ON, the counter decreases by 1.
The lower limit of the counter is 1. It can be reset to 0 by “Delete log” switch or CONSULT-II.
Count Up Type
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 or CONSULT-II.
Error Item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items
