Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS00485
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WAR NING :
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Trouble DiagnosisNKS00486
AV COMMUNICATION SYSTEM
Do not apply voltage of 7.0 V or higher to the measurement terminals.
Use the tester with its open terminal voltage being 7.0 V or less.
Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
Precautions for Harness RepairNKS00487
AV COMMUNICATION SYSTEM
Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in).]
Do not perform bypass wire connections for the repair parts.
(The spliced wire will become separated and the characteristics
of twisted line will be lost.)

DIAGNOSIS SYSTEMPFP:00000
Multifunction Switch Self-Diagnosis FunctionNKS0048T
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 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.

VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal and
the signals recognized by the system.
SPEAKER TEST
When selecting “Speaker Test”, speaker diagnosis screen is dis-
played. When pressing “Start”, test tone emits from the speaker. At
that time, when pressing “Start”, test tone emits from next speaker.
Then, when pressing the “END”, test tone stops.
NOTE:
The frequency of test tone emitted from each speaker is as follows.
CLIMATE CONTROL

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.
