Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009460702
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Precaution for SRS "AIR BAG" and "S EAT BELT PRE-TENSIONER" Service
INFOID:0000000009460703
• Do not use electrical test equipment to check SRS ci rcuits unless instructed to in this Service Manual.
• 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 pre-
tensioner to deploy. Therefore, do not work on any SR S connectors or wires until at least 3 minutes have
passed.
• 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 rust
before installation and replace as required.
• 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 seat mounted front side air bag m odule standing with the stud bolt side facing down.
• 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.

COMPONENT PARTS
Front Seat Belt Pre-tensioner
INFOID:0000000009460710
The seat belt pre-tensioner system wi th 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 im pact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the shoulder belt pre-tensioner (1) as well
as the lap belt pre-tensioner (2). 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
twisting of the ELR shaft, and a relaxation of the ches t-area seat belt web tension while maintaining force.
Air Bag Diagnosis Sensor UnitINFOID:0000000009460711
The air bag diagnosis sensor unit is located under the center con-
sole assembly. The air bag diagnosis sensor unit receives signals
from multiple SRS sensors and cont rols the deployment of the air
bags. The deployment of the air bags depends on the type and
severity of the collision. The air bag diagnosis sensor unit has self-
diagnosis capability through the use of the CONSULT as well as
flash codes displayed by the air bag warning lamp.
Crash Zone SensorINFOID:0000000009460712
The crash zone sensor is located behind the radiator and under-
neath the front air duct. The crash zone sensor sends signals to the
air bag diagnosis sensor unit during a frontal collision. This sensor
may be identified by a yellow connector.
Front Side Air B ag Satellite SensorINFOID:0000000009460713
The front side air bag satellite sensors are located on the front center
pillar LH and RH next to the seat belt pretensioners. The front side
air bag satellite sensors send signals to the air bag diagnosis sensor
unit during a side collision. Thes e sensors may be identified by yel-
low connectors.

Trouble Diagnosis without CONSULTINFOID:0000000009460726
DIAGNOSIS MODE
NOTE:
Diagnosis Mode can not be entered if a malfunction is not detected in User Mode.
1. Turn ignition switch ON.
2. After AIR BAG warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two more times (3 times total).
5. Turn ignition switch ON.
SRS is now in Diagnosis Mode. Refer to SRC-23, "Flash Code Index"
.
SRS History CheckINFOID:0000000009460727
SRS HISTORY CHECK
1. Check repair history of the SRS. If no repairs have been made, perform SRC-15, "SRS Operation
Check". If repairs have been made, GO TO step 2.
2. Erase "SELF-DIAG [PAST]" after repair. Refer to SRC-17, "SRS Final Check"
.
SRS Final CheckINFOID:0000000009460728
DIAGNOSIS MODE
1. Connect CONSULT.
2. Confirm that zero point reset of OCS is complete.
3. If no DTCs are detected on “SELF- DIAG RESULTS [CURRENT]”, repair of SRS is completed. Go to step
4.
If any DTCs are detected on “SEL F-DIAG RESULTS [CURRENT]”, t he malfunction has not been repaired
completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to
SRC-15, "SRS Operation Check"
.
4. Touch “ERASE”. NOTE:
Touching “ERASE” will clear the SRS memory of the malfunction (“SELF-DIAG [PAST]”). If “SELF-
DIAG [PAST]” is not erased, User Mode may s how the previous system malfunction even if the
malfunction has been repaired completely.
5. Check that no malfunction is detected in “SELF-DIAG [PAST]”.
6. Exit Diagnosis Mode and disconnect the CONSULT.
7. Perform SRS Operation Check. Refer to SRC-15, "SRS Operation Check"
.
CONSULT Function (AIR BAG)INFOID:0000000009460729
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
CONSULT can display each diagnostic item using the diagnostic test modes shown following.
Diagnostic Test Mode Diagnostic Item Description
Self Diagnostic Result SEL F-DIAG RESULT [CURRENT]A current Self-diagnosis result (also indicated by the number of
warning lamp flashes in the Diagnosis mode) is displayed on the
CONSULT screen in real time. This refers to a malfunctioning part
requiring repairs.
Data Monitor DATA MONITOR Displays air bag diagnosis sensor unit input/output data in real time.
Ecu Identification ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identifica-
tion number) or part number is displayed. Air bag diagnosis sensor
unit has individual ECU discriminated number (identification num-
ber) or part number based on model and equipment.
Trouble Diagnostic Record TROUBLE DIAG RECORD [PAST] With TROUBLE DIAG RECORD, diagnosis results previously
erased by a reset operation can be displayed on the CONSULT
screen.
