Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           EHS001DP


The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along                            B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front              C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:                                                                                                                 D
G    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 must be per-
     formed by an authorized NISSAN/INFINITI dealer.                                                                     E
G    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 SRS section.                                                                                    F
G    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 and/or orange harnesses or

Precautions for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service

G   Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.       SRS
G   Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
    utes.
    For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt   I
    pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
    have passed.
G   The air bag diagnosis sensor unit must always be installed with the arrow mark "" pointing toward the
    front of the vehicle for proper operation. Also check the air bag diagnosis sensor unit for cracks, deformi- J
    ties or rust before installation and replace as required.
G   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.                                                  K
G   Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
    side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
    down.                                                                                                          L
G   Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
G   After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Front Seat Belt Pre-tensioner with Load Limiter                                  EHS001G4


The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
                                                                              WHIA0225E

The occupant classification system identifies different size occupants, out of position occupants, and detects if
child seat is present in the front passenger seat. The occupant classification system receives inputs from the
occupant classification system sensor (located inside the passenger seat cushion assembly) and belt tension
sensor (part of the passenger front seat belt assembly and located at the belt anchor location). Depending on            B
classification of passenger, the occupant classification system sends a signal to the air bag diagnosis sensor
unit. The air bag diagnosis sensor unit uses this signal to determine deployment or non deployment of the pas-
senger front air bag in the event of a collision. Depending on the signal received, the air bag diagnosis sensor         C
unit can disable the passenger front air bag completely. If this occurs the air bag diagnosis sensor unit will turn
on the PASS AIR BAG OFF indicator.

Trouble Diagnosis Introduction                                                                              EHS001G9


CAUTION:
G  Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
   this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
   nectors.
G  Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace
   it with a new one.
G  Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using "AIR BAG" warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the "AIR BAG" warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the "AIR BAG" warning lamp and CONSULT-II are as follows:
                                     User mode                Diagnosis mode               Display type
   "AIR BAG" warning lamp               X                           X                    ON-OFF operation
        CONSULT-II                      --                          X                       Monitoring

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR

DIAGNOSTIC PROCEDURE 2
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
in self-diagnosis depending on control unit which carries out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the
    data link connector.
