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

EHS000M8

The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used al ong with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain types of collision. This system includes seat belt switch inputs and dual st age 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 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 Manual.

WARNING:

● To avoid rendering the SRS inopera tive, whi ch could incr ease the risk of pe rsonal injury or death

in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

● Improper maintenance, inc luding incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional ac tiv atio n o f the s ys tem . F or re moval of Spiral C ab le and A ir Bag Module, see the SRS sec tion.

● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

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

● Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

● Before serv ic ing th e S RS , t ur n igni t io n s wit c h OF F, disconnect b oth ba tt e ry ca bl e s an d wai t at l ea st 3 m in -

utes. 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 “⇐” pointing towards the front of the

vehicle for proper operation. Also check diagnos is sensor unit for cr acks, deformities or rust before installation and replace as required.

● The spiral ca bl e must be aligned with the ne utra l p os ition since its rotatio ns a r e l im ite d. Do not attemp t 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.

The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ON or START position.

The collision m odes for which su pp le me ntal restraint syst em s are a ct iv ate d are different among the SR S sy s tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a side collision. SRS configurations which are activated for some collision modes are as follows;

SRS configuration Frontal collision Left side collision Right side collision Driver air bag module × —— Front passenger air bag module × —— Front LH seat belt pre-tensioner × —— Front RH seat belt pre-tensioner × —— Front LH side air bag module — × — Front RH side air bag module — — × LH side curtain air bag module — × — RH side curtain air bag module — — ×

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-Tensioner With Load Limiter EHS0009F

The seat belt pre-tensioner system with load limiter is installed to both the driver's seat and the front passenger's seat. It operates simultaneously with the SRS air bag sy stem in the event of a fron tal 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 t hrown forward in a collision a nd the restraining fo rce of the seat belt exceeds a spec ified level, the load limiter permits the specified extension of the seat belt by the twisting of the ELR shaft, and a relaxation of the chest-area seat belt
