PRECAUTIONS
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.

• 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 restrain t systems are activated are different among the SRS
systems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-ten-
sioners are activated in a frontal collision but not in a side collision.

DIAGNOSIS SYSTEM (AIR BAG)
Diagnosis DescriptionINFOID:0000000009460723
CAUTION:
• Do not use electrical test equipment on any circui t related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be id entified by yellow and/or orange harness con-
nectors.
• Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace it
with a new one.
• Keep ground connections clean.
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
1. Obtain information about the symptom.
- WHAT - vehicle model
- WHEN - date, frequencies
- WHERE - road conditions
- HOW - operating conditions, symptoms, passengers
2. Perform Preliminary Check.
-Battery
- Fuses
- Harness connections
DIAGNOSIS METHODS
SRS self-diagnosis results can be read by using the AIR BAG warning lamp or CONSULT.
The User Mode is for the customer (driver). This m ode warns the driver of a system malfunction through the
AIR BAG warning lamp.
The Diagnosis Mode is for the technician. This mode hel ps the technician locate the malfunctioning circuit or
part.
SRS Operation CheckINFOID:0000000009460724
USER MODE

.
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.
