sensor circuit.
Repair order (ªRecheck SRS at each replacement.º)
1. Visually check the wiring harness connection.
2. Replace the harness if it has visible damage.
3. Replace the LH side air bag (satellite) sensor.
4. Replace the diagnosis sensor unit.
5. Replace the related harness.
* Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is eliminated
using the air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still observed, proceed to the next
step. When malfunction is eliminated, further repair work is not required.

DIAGNOSTIC PROCEDURE 7NJRS0049S02Final checking after repairing SRS by using ªAIR BAGº warn-
ing lamp Ð Diagnosis mode and User mode
1. After repairing SRS connect both battery cables.
2. Open driver's door.
3. Turn ignition switch from ªOFFº to ªONº.
4. ªAIR BAGº warning lamp operates in Diagnosis mode as fol-

No©Visually check the wiring harness connection of diagnosis sensor unit. If the harness
connection check result is OK, replace diagnosis sensor unit.
5 CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK©Replace diagnosis sensor unit.
NG©Connect ªAIR BAGº warning lamp and diagnosis sensor unit connector properly. If ªAIR
BAGº warning lamp still does not go off, replace harness.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NJSC0001The 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 system composition which is available to NISSAN MODEL N16 is as follows (The compo-
sition 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 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).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
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. For removal of Spiral Cable and Air
Bag Module, see the RS 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 harness connector.
