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, 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 Y61 is as follows (The com-
position varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the
steering wheel), front passenger air bag module (located on the instrument panel on passenger side),
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), 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
RS-1002

Maintenance Items
CAUTION:
Do not use electrical test equipment to check SRS circuit.
1. Check operation of ªAIR BAGº and ªSEAT BELTº warning
lamps (ªSEAT BELTº warning lamp can be used for check-
ing seat belt pre-tensioner on models except for Europe.).
After turning ignition key to ªONº position, both warning
lamps illuminate. The ªAIR BAGº warning lamp will go off
after about 7 seconds if no malfunction is detected. The
ªSEAT BELTº warning lamp will also go off after about 7
seconds after seat belt has been fastened and no malfunc-
tion is detected. (When seat belt has not been fastened, the
warning lamp continues to illuminate until seat belt is fas-
tened.)
If any of the following warning lamp conditions occur, imme-
diately check the air bag or seat belt pre-tensioner system.
Refer to RS-1032 for details.
+The ªAIR BAGº or ªSEAT BELTº warning lamp does not illu-
minate when the ignition switch is turned ªONº.
+The ªAIR BAGº or ªSEAT BELTº (with seat belt fastened)
warning lamp does not go off about 7 seconds after the igni-
tion switch is turned ªONº.
+The ªAIR BAGº or ªSEAT BELTº (with seat belt fastened)
warning lamp blinks after about 7 seconds after the ignition
switch is turned ªONº.
2. Visually check SRS components
(1) Diagnosis sensor unit
+Check diagnosis sensor unit and bracket for dents, cracks or
deformities.
+Check connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
+Remove 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.
+Install driver air bag module to steering wheel to check fit or
alignment with the wheel.
+Check steering wheel for excessive free play.
+Install passenger air bag module to instrument panel to
check fit or alignment with the instrument panel.
+Install side air bag module to seat back to check fit and
alignment with the seat.
(3) Spiral cable
+Check spiral cable for dents, cracks, or deformities.
+Check connectors and protective tape for damage.
+Check steering wheel for noise, binding or heavy operation.
(4) Main harness and body harness
+Check connectors for poor connections, damage, and termi-
nals for deformities.
+Check harnesses for binding, chafing or cut.
(5) Seat belt pre-tensioner
+Check harness cover and connectors for damage, terminals
for deformities, and harness for binding.
+Check belts for damage and anchors for loose mounting.
+Check retractor for smooth operation.

+Perform self-diagnosis for seat belt pre-tensioner using seat
belt warning lamp or CONSULT-II. Refer to ªSelf-diagnosisº
for details.
(6) Satellite sensor
+Check satellite sensor (including bracket portion) for dents,
cracks or deformities.
+Check connectors for damage, and terminals for deformities.
CAUTION:
Replace previously used special bolts, ground bolt and nuts
coated with bonding agent.
