Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)“AIR BAG”AND“SEAT BELT
PRE-TENSIONER”
NLRS0001The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to NISSAN MODEL V10 is as follows (The composition var-
ies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver’s air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
WARNING:
+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 should be per-
formed by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTION FOR SEAT BELT SERVICENLRS0002CAUTION:
+Before removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect both
battery cables and wait at least 3 minutes.
+Do not use electrical test equipment for seat belt pre-tensioner connector.
+After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to“SRS Operation Check”for details. (RS-45)
+Do not disassemble buckle or seat belt assembly.
+Replace anchor bolts if they are deformed or worn out.
+Never oil tongue and buckle.
+If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
+If webbing is cut, frayed, or damaged, replace seat belt assembly.
+When replacing seat belt assembly, use a genuine seat belt assembly.
After A CollisionNLRS0002S01WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the
collision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly if:
+The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
+The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
+The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for dam-
age or distortion and repair as necessary before installing a new seat belt assembly.
+Anchor bolts are deformed or worn out.

PRECAUTIONS FOR SRS“AIR BAG”AND“SEAT BELT PRE-TENSIONER”SERVICENLRS0007+Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
+Before servicing the SRS, turn ignition switch“OFF”, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
+Diagnosis sensor unit must always be installed with their arrow marks“⇐”pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
+The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
+Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module (built-in type) standing with stud bolt side setting
bottom.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Disposal of Air Bag Module and Seat Belt Pre-
tensioner
NLRS0022+Before disposing of air bag module and seat belt pre-tensioner,
or vehicles equipped with such systems, deploy the systems.
If such systems have already been deployed due to an
accident, dispose of them as indicated in“DISPOSING OF AIR
BAG MODULE AND SEAT BELT PRE-TENSIONER”(RS-36).
+When deploying the air bag module and seat belt pre-
tensioner, always use the Special Service Tool; Deployment
tool KV99106400.
+When deploying the air bag module and seat belt pre-
tensioner, stand at least 5 m (16 ft) away from the deployment
component.
+When deploying air bag module and seat belt pre-tensioner, a
fairly loud noise is made, followed by smoke being released.
The smoke is not poisonous, however, be careful not to inhale
smoke since it irritates the throat and can cause choking.
+Always activate one air bag module at a time.
+Due to heat, leave air bag module unattended for more than
30 minutes after deployment. Also leave seat belt pre-ten-
sioner unattended for move than 10 minutes after deployment.
+Be sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
+Never apply water to the deployed air bag module and seat
belt pre-tensioner.
+Wash your hands clean after finishing work.
+Place the vehicle outdoors with an open space of at least 6 m
(20 ft) on all sides when deploying air bag module and seat belt
pre-tensioner while mounted in vehicle.
+Use a voltmeter to make sure the vehicle battery is fully
charged.
+Do not dispose of the air bag module and seat belt pre-ten-
sioner un-deployed.

Trouble Diagnoses Introduction=NLRS0043CAUTION:
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
+Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
+Keep ground portion clean.
DIAGNOSIS FUNCTIONNLRS0043S01The SRS self-diagnosis results can be read by using“AIR BAG”warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes—“User mode”and“Diagnosis mode”.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the“AIR BAG”warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the“AIR BAG”warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
“AIR BAG”warning lamp X X ON-OFF operation
CONSULT-II—X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by“AIR BAG”warning lamp.
DIAGNOSIS MODE FOR CONSULT-IINLRS0043S02+“SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.
+“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.
+“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
+“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber (refer to the table below). This number will be displayed on the CONSULT-II screen. When replacing
the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with
a correct unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL V10, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A910
Models with dual air bags and seat belt pre-tensioner A911
Models with dual air bags, side air bag and seat belt pre-tensioner A912
