Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

NGEL0001

The Supplemental Restraint System “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with a seatbelt, helps to reduce the risk of severe injury to the driver and front passenger in certain types of collisions.The Supplemental Restraint System consists of a driver air bag module (located in the center of the steeringwheel), a front passenger air bag module (located on the instrument panel on the passenger side), seat beltpre-tensionsers, a diagnosis sensor unit, a crash zone sensor (4WD models), a warning lamp, wiring harnessand spiral cable

Information necessary to service the system safely is included in the RS section of this Service Manual.

WARNING:

쐌 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 formed by an authorized NISSAN dealer.

per-쐌 Improper maintenance, including incorrect removal and installation of the SRS, can lead to sonal injury caused by unintentional activation of the system For removal of Spiral Cable and Air Bag Module, see RS section.

per-쐌 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 (except “SEAT BELT PRE-TENSIONER”) cov- ered with yellow insulation, either just before the harness connectors or for the complete harness, are related to the SRS.

Wiring Diagrams and Trouble Diagnosis

NGEL0002

When you read wiring diagrams, refer to the following:

쐌 GI-10, “HOW TO READ WIRING DIAGRAMS”

쐌 EL-9, “POWER SUPPLY ROUTING” for power distribution circuit

When you perform trouble diagnosis, refer to the following:

쐌 GI-34, “HOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSIS”.

쐌 GI-23, “HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”.

Check for any Service bulletins before servicing the vehicle
