PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front sea t belt , helps t o redu ce th e r isk or s everi ty of injury to th e driv er an d front passenge r for c ertain
types of collision. Info rmation necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
● To avoid rendering the SRS inoperativ e, which cou ld increase the risk of persona l 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, in cluding incorrect removal a nd installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For rem ova l of Sp iral Ca ble an d Ai r
Bag Module, see the SRS section.
● Do not use electrical test equipme nt on any circuit related to the SRS unle ss instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnes ses or
harness connectors .
AHS000QA
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
AHS000QB
● Do not use electrical test eq uipment to check S RS circuits unless instructed to in this Service Manual.
● Before serv ic in g th e S RS , tu r n i gni ti on swi t ch OFF, disconnect bo t h b att ery ca bl es an d wa it a t le as t 3 mi n-
utes.
For approximately 3 min utes a fter the cables are rem oved, it is s till pos sible for the air bag and se at 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 diagnosis sensor unit for cracks, deformities or rust before installation and replace as requi red.
● 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.
● 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 af ter replacing any components.
● After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Wiring Diagrams and Trouble Diagnosis AHS000R4
When you read wiring diagrams, refer to the following:
● GI-14, "How to Read Wiring Diagrams" in GI section
● PG-2, "POWER SUPPLY ROUTING" in PG section
When you perfo rm trouble diagnosis, refer to the following:
● GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section
● GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section
Check for any servi ce bulletins before servicing the vehicle.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) PFP:28556 SRS Configuration AHS000QF
PHIA0037E
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 system s are activated are di fferent am on g the SRS systems. 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 — — ×
Front Seat Belt Pre-Tensioner with Load Limiter AHS000QG
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 system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal coll ision with an impact exce edin g a spe cif ied le vel
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 i n a collision and
the restraining forc e of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaf t , and a r el ax atio n of the ch est -a r ea seat bel t
web tension while maintaining force.

TROUBLE DIAGNOSIS
TROUBLE DIAGNOSIS PFP:00004 Trouble Diagnosis Introduction AHS000QI
CAUTION:
● Do not use electrical test equipme nt on any circuit related to the SRS unle ss instructed to in this
Service Manual. SRS wiring harness can be identified by yellow and/or oran ge harnesses or harness connector.
● Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
● Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be rea d by using “AIR BAG” warning l amp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system malfunction 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” war ning 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
NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.
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 symptoms or conditions for a customer complaint.
Information from Customer

DIAGNOSIS MODE FOR CONSULT-II
● “SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displaye d on the CONSULT-II screen in real time. This refe rs to a malfun ctioning part requiring
repairs.
● “SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results ar e not erased until memory erasing is executed.
● “TROUBLE DIAG RECORD”
With TROUBLE DI AG RECORD, diagnosis results prev iously erased by a reset operatio n can be displayed on the CONSULT-II screen.
● “ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classification number. This number will
be displayed on the CONSULT-II screen, as shown. When
replacing the dia gnosis sens or unit, refe r to the part number fo r
the compatibility. After installation, replacement with a correct
unit can be checked by confirming this classification number on
the CONSULT-II screen.
After repair, make sure the discriminated number of diagnosis
sensor unit installed to vehicle are same. Refer to SRS-39,
"ECU DISCRIMINATED NO. " .
