PRECAUTIONS
Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER” NJEL0001
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” 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 the RS section of 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.
Wiring Diagrams and Trouble Diagnosis
NJEL0002
When you read wiring diagrams, refer to the following:
+ Refer to GI-11, “HOW TO READ WIRING DIAGRAMS”
+ Refer to EL-10 , “POWER SUPPLY ROUTING” for power distribution circuit
When you perform trouble diagnosis, refer to the following:
+ Refer to GI-32, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”
+ Refer to GI-21, “HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”
Check for any Service bulletins before servicing the vehicle.
