PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS004X5
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER ”, used along
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
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:

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.

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.

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.
Precautions for WorkEIS004X6

When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.

When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-
nent with a shop cloth or vinyl tape to protect it.

Protect the removed parts with a shop cloth and keep them.

Replace a deformed or damaged clip.

If a part is specified as a non-reusable part, always replace it with new one.

Be sure to tighten bolts and nuts securely to the specified torque.

After re-installation is completed, be sure to check that each part works normally.

Follow the steps below to clean components.
–Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the
fouled area.
Then rub with a soft and dry cloth.
–Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub
with a soft and dry cloth.

Do not use organic solvent such as thinner, benzene, alcohol, or gasoline.

For genuine leather seats, use a genuine leather seat cleaner.

SE-94
FRONT SEAT
Revision: November 20092006 QX56
REMOVAL
CAUTION:

When removing or installing the seat trim, handle it carefully to keep dirt out and avoid damage.

Before removing the front seat, turn the ignition switch off, disconnect both battery cables and
wait at least 3 minutes.

When checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.

Do not drop, tilt, or bump the side air bag module while installing the seat. Always handle it with
care.

After front side air bag module inflates, front seatback assembly must be replaced.

Front passenger seat is equipped with an Occupant Classification System sensor and control
module. Do not disassemble front passenger seat cushion assembly or remove the trim as this
will affect the Occupant Classification System calibration.

Always replace passenger seat cushion as an assembly.
1. Slide the seat until the four body mounting bolts are visible and a tool can be inserted. NOTE:

If disassembling the seat after removal, set the front/rear cushion lifters to the top position.
2. Disconnect both battery cables and wait at least 3 minutes.
3. Disconnect the side air bag module harness connector.
4. Remove the four body mounting bolts.
5. Disconnect the power seat harness connectors and remove the seat from the vehicle. NOTE:
When removing and installing the seat, use shop cloths to protect the vehicle from damage.
INSTALLATION
Installation is in the reverse order of removal.
Disassembly and AssemblyEIS004YT
SEATBACK TRIM AND PAD
WARNING:
Removal of front side air bag module should only be done to allow deployment of front side air bag
module prior to disposal of seatback assembly.
NOTE:
Only complete seatback assemblies can be replaced on vehicles equipped with side air bags.
Be sure to set the front/rear cushion lifter to the top position.

EHS0016A
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER ”, used along
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
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:

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.

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.

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.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceEHS0016B

Do not use electrical test equipment to check SRS circuits 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 bags and seat belt
pre-tensioners to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

The air 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 module 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.
Occupant Classification System PrecautionEHS0016C
Replace control unit and passenger front seat cushion as an assembly.

Trouble Diagnosis IntroductionEHS0016M
CAUTION:

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.

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.
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:
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.
