Removal and Installation
CAUTION:
lBefore removing the rear suspension assembly, discon-
nect the ABS wheel sensor and headlamp leveling sen-
sor from the assembly. Failure to do so may result in
damage to the sensor wires and the sensor becoming
inoperative.
lRemove suspension assembly.
1. Disconnect parking brake cable from caliper and remove
brake caliper and rotor.
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop out.
Make sure brake hose is not twisted.
2. Using a transmission jack, raise torsion beam a little, and
remove nuts and bolts from the trailing arm, shock absorber
assembly (lower side) and lateral link.
3. Lower transmission jack, and remove suspension.
4. Remove shock absorber assembly.
lInstall suspension assembly.
CAUTION:
Refill with new brake fluid ªDOT 4º.
Never reuse drained brake fluid.
lAfter installation of the suspension assembly the head-
lamp leveling sensor has to be recalibrated. Refer to EL
section (models equipped with xenon headlamps only).
1. Attach torsion beam, at trailing arm and lateral link, to
vehicle. Do not tighten bolts at this time.
2. Using a transmission jack, place lateral link and control rod
horizontally against torsion beam. Tighten lateral link on
vehicle.
3. Attach shock absorber assembly to vehicle. Then tighten the
lower side of shock absorber assembly.
4. Lower torsion beam to fully extended position. Remove
transmission jack and tighten torsion beam, at trailing arm, to
specified torque.Refer to RA-9.
5. Install ABS-wheel sensor.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, help to reduce the risk or severity of injury to the driver and front passenger in certain types
of collision. The SRS system composition which is available to NISSAN MODEL P11 is as follows (The
composition varies according to the destination and optional equipment):
lFor a frontal collision
The Supplemental Restraint System consists of driver's air bag module (located in the center of the
steering wheel), front passenger's air bag module (located on the instrument panel on passenger's side),
seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
lFor a side collision
The Supplemental Restraint System consists of air bag modules (located in the outer side of front seats),
satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal collision),
wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision).
WARNING:
lTo 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 dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and SRS wiring harnesses except ªSEAT BELT PRE-TENSIONERº
connectors can be identified by yellow harness connector (and with yellow harness protector or
yellow insulation tape before the harness connectors).
CAUTION:
lBefore removing the seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect
both battery cables and wait at least 3 minutes.
lDo not use electrical test equipment for seat belt pre-tensioner connector.
lAfter replacing or installing seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to ªSRS Operation Checkº (RS-37) for details.
lDo not disassemble buckle or seat belt assembly.
lReplace anchor bolts if they are deformed or worn out.
lNever oil tongue and buckle.
lIf any component of seat belt assembly is questionable, do not repair. Replace the whole seat
belt assembly.
lIf webbing is cut, frayed, or damaged, replace seat belt assembly.
lWhen replacing seat belt assembly, use a genuine seat belt assembly.
lAfter any collision, inspect all seat belt assemblies, including retractors and other attached
hardwares (i.e., guide rail set).
PRECAUTION

Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
lDo not use electrical test equipment to check the SRS unless instructed to do in this Service Manual.
lBefore servicing the SRS, turn ignition switch ªOFFº, 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.
lDiagnosis sensor unit must always be installed with their arrow marks ªSº 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.
lThe 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.
lHandle air bag module carefully. Always place driver's and passenger's air bag modules with the pad
side facing upward and place side air bag module (built-in type) standing with stud bolt side setting bot-
tom.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.

Description
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in ªONº or ªSTARTº
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS
systems. For example, the driver's air bag module and passenger's air bag module are activated in a fron-
tal collision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows;

Maintenance Items
CAUTION:
Do not use electrical test equipment to check SRS circuit.
1. Check operation of ªAIR BAGº warning lamp.
After turning ignition key to ªONº position, the ªAIR BAGº
warning lamp illuminates. The ªAIR BAGº warning lamp will
go off after about 7 seconds if no malfunction is detected.
If any of the following warning lamp conditions occur, imme-
diately check the air bag system. Refer to ªSRS-Operation
Checkº for details. (RS-37)
lThe ªAIR BAGº warning lamp does not come on when the
ignition switch is turned ªONº.
lThe ªAIR BAGº warning lamp does not go off about 7 sec-
onds after the ignition switch is turned ªONº.
lThe ªAIR BAGº warning lamp blinks about 7 seconds after
the ignition switch is turned ªONº.
2. Visually check SRS components.
(1) Diagnosis sensor unit
lCheck diagnosis sensor unit and bracket for dents, cracks or
deformities.
lCheck connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
lRemove air bag module from steering wheel, instrument
panel or seat back. Check harness cover and connectors for
damage, terminals for deformities, and harness for binding.
lInstall driver's air bag module to steering wheel to check fit
or alignment with the wheel.
lCheck steering wheel for excessive free play.
lInstall passenger's air bag module to instrument panel to
check fit or alignment with the instrument panel.
lInstall side air bag module to seatback to check fit and align-
ment with the seat.
(3) Spiral cable
