Precautions
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 R20 is as follows (The composition
varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver 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.
IFor 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:
ITo 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.
IImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
IDo 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.
PRECAUTIONS FOR SRS ªAIR BAGº AND ªSEAT BELT PRE-TENSIONERº SERVICE
IDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
IBefore 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.
IDiagnosis sensor unit must always be installed with their arrow marks ª+º 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.
IThe 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.
IHandle 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.
IConduct self-diagnosis to check entire SRS for proper function after replacing any components.
IAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
WIRING DIAGRAMS AND TROUBLE DIAGNOSIS
When you read wiring diagrams, refer to the following:
IGI-10, ªHOW TO READ WIRING DIAGRAMSº
IEL-6, ªPOWER SUPPLY ROUTINGº for power distribution circuit
When you perform trouble diagnosis, refer to the following:

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, 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 fol-
lowing ªAIR BAGº warning lamp conditions occur, immediately
check the air bag system. Refer to RS-36 for details.
IThe ªAIR BAGº warning lamp does not illuminate when the
ignition switch is turned ªONº.
IThe ªAIR BAGº warning lamp does not go off about 7 seconds
after the ignition switch is turned ªONº.
IThe ªAIR BAGº warning lamp blinks after about 7 seconds after
the ignition switch is turned ªONº.
2. Visually check SRS components.
1) Diagnosis sensor unit
ICheck diagnosis sensor unit and bracket for dents, cracks and
deformities.
ICheck connectors for damage, and terminals for deformities.
2) Air bag module and steering wheel
IRemove air bag module from steering wheel, instrument panel
or seatback. Check harness cover and connectors for damage,
terminals for deformities, and harness for binding.

CAUTION:
IBefore servicing SRS, turn the ignition switch off, discon-
nect both battery cables and wait at least 3 minutes.
IThe special bolts are coated with bonding agent while the
other bolt is for ground. Do not use old bolts after removal;
replace with new ones.
ICheck diagnosis sensor unit for proper installation.
ICheck diagnosis sensor unit to ensure it is free of
deformities, dents, cracks or rust. If they show any visible
signs of damage, replace them with new ones.

IReplace diagnosis sensor unit if it has been dropped or
sustained an impact.
IAfter replacement of diagnosis sensor unit, perform self-
diagnosis for SRS. Refer to ªSRS Operation Checkº for
details. (RS-36)

INSTALLATION
1. Set the front wheels in the straight-ahead position.
2. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left (counterclock-
wise) about 2.5 revolutions from the right end position. Align the
two marks (
).
CAUTION:
IThe spiral cable may snap due to steering operation if the
cable is installed in an improper position.
IAlso, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned up to
about 2.5 turns from the neutral position to both the right
and left.
3. Connect spiral cable connector and tighten with screws.
4. Install steering column covers. And make sure the harness do
not get caught between inner steering cover and steering col-
umn.
5. Install steering wheel, aligning with spiral cable pin guides, and
pull spiral cable through.
6. Connect horn connector (or horn/audio connector) and engage
spiral cable with pawls in steering wheel. Move driver air bag
module connector away from steering wheel lower lid opening.
7. Tighten nut.
:30-40N×m (3.1 - 4.1 kg-m, 22 - 30 ft-lb)
8. Position driver air bag module and tighten with new special
bolts.
9. Connect driver air bag module connector and diagnosis sensor
unit connector.
10. Install steering switches and lids.
11. Conduct self-diagnosis to ensure entire SRS operates properly.
(Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
12. Turn steering wheel to the left end and then to the right end fully
to make sure that spiral cable is set in the neutral position.
If ªAIR BAGº warning lamp blinks or stays ON (at the user
mode), it shows the spiral cable may be snapped due to its
improper position. Perform self-diagnosis again (use CON-
SULT-II or warning lamp). If a malfunction is detected, replace
the spiral cable with a new one.
13. Perform self-diagnosis again to check that no malfunction is
detected.
