PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EHS00151

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
harness connectors.
G
Precautions for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
EHS00152

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 bags and seat belt I
pre-tensioners 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 air bag diagnosis sensor unit for cracks, deformities or J
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.
M
Occupant Classification System Precaution EHS00153

Replace control unit and passenger front seat cushion as an assembly.

The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or
START position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module, front passenger air bag module, seat belt buckle pre-tensioner K
assemblies and the front seat belt pre-tensioners are activated in a frontal collision but not in a side collision.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-tensioner with Load Limiter EHS00158

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
SRS444
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.
Front Side Air Bag EHS00159

Front side air bag modules are built into the front seatback assemblies.
Vehicles with side air bags are equipped with labels as shown.

WHIA0008E

Side Curtain Air Bag EHS0015A

Side curtain air bag modules are located above the vehicle headlining.
Vehicles with side curtain air bags are equipped with labels as
shown.

WHIA0041E

Occupant Classification System (OCS) EHS001MK

The occupant classification system (OCS) identifies different size occupants, out of position occupants, and
detects if child seat is present in the front passenger seat. The OCS receives inputs from the occupant classi-
fication sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the pas-
senger front seat belt assembly and located at the belt anchor location). Depending on classification of the
passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit
uses this signal and the seat belt buckle switch RH signal to determine deployment or non deployment of the
passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis
sensor unit can disable the passenger front air bag completely.
NOTE:
In case of customer concern, CONSULT-II can be used to confirm the passenger air bag status (readiness).

TROUBLE DIAGNOSIS PFP:00004

Trouble Diagnosis Introduction EHS0015D

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
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
