Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TEN-
SIONER"

INFOID:0000000004205513

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.Infor-

mation necessary to service the system safely is included in the SR and SB section of this Service Manual.

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 performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004501287

NOTE:

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

This vehicle is equipped with a push-button ignition switch and a steering lock unit.

If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure

below before starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-

nected and the steering wheel can be turned.

4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn

the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering

wheel will lock when the push-button ignition switch is turned to LOCK position.)

6. Perform self-diagnosis check of all control units using CONSULT-III.

Precaution for Seat Belt Service

INFOID:0000000004205514

CAUTION:

• Before removing the front seat belt pre-tensioner assembly, turn the ignition switch off, disconnect

both battery cables and wait at least 3 minutes.

• Do not use electrical test equipment for front seat belt pre-tensioner connector.

• After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat belt

pre-tensioner connector, check the system function. Refer to 

SRC-12, "SRS Operation Check"

AFTER A COLLISION

WARNING:

Inspect all seat belt assemblies including retractors and attaching hardware after any collision.

NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced

unless the collision was minor and the belts show no damage and continue to operate properly. Fail-

ure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use dur-

ing a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-

tensioned should be replaced even if the seat belts are not in use during a frontal collision in which

the air bags are deployed.

Replace any seat belt assembly (including anchor bolts) if:

• The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and

buckles show no damage and continue to operate properly).

• The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)

• The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage

or distortion and repair as necessary before installing a new seat belt assembly.

• Anchor bolts are deformed or worn out.

• The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in

which the air bags are deployed.

PRELIMINARY CHECKS

1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should

sound for about six seconds.

b. Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should

stop.

2. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-III, and air bag warning

lamp. Refer to 

SRC-12, "SRS Operation Check"

.

3. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Make sure guide

swivels freely and that webbing lays flat and does not bind in guide. Make sure height adjuster operates

properly and holds securely.

5. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Make sure that webbing returns smoothly and completely into the retractor. If

the seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth. Dirt built up in

the loops of the upper anchors can cause the seat belts to retract slowly.

c.

Fasten the seat belt. Check that the seat belt returns smoothly and completely to the retractor. If the web-

bing does not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT

TAPE SET” and perform the following steps. 

Inspect the front seat belt though-anchor 

1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.

2. Use a clip or other device to hold the seat belt at the center pillar webbing opening.

3. Pass a thin wire though the though-anchor webbing opening. Hold both ends of the wire and pull it

taunt while moving it up and down several times along the webbing opening surface to move matter

stuck there. 

4. Any dirt that can not be removed with the wire can be removed by cleaning the opening with a clean

cloth.

5. Apply tape at the point where the webbing contacts the though-anchor webbing opening. 

NOTE:

Apply the tape so that there is no looseness or wrinkling.

6. Remove the clip holding the seat belt and check that the webbing returns smoothly.
