Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) ªAIR BAGº AND ªSEAT BELT
PRE-TENSIONERº
NJRS0006The 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 N16 is as follows (The composition
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).
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. SRS wiring harnesses can be identified by yellow harness connector.
PRECAUTIONS FOR SRS ªAIR BAGº AND ªSEAT BELT PRE-TENSIONERº SERVICENJRS0007+Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
+Before 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.
+Diagnosis sensor unit must always be installed with their arrow marks ªÜº 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 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.
WIRING DIAGRAMS AND TROUBLE DIAGNOSISNJRS0008When you read wiring diagrams, refer to the following:
+GI-11, ªHOW TO READ WIRING DIAGRAMSº
+EL-10, ªPOWER SUPPLY ROUTINGº for power distribution circuit
When you perform trouble diagnosis, refer to the following:
+GI-32, ªHOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSESº
