PRECAUTIONS

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSION-
ER"

INFOID:0000000004205819

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 SR 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 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

Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

Precautions Necessary for Steering Wheel Rotation after Battery Disconnect

INFOID:0000000004460415

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.

1. When measuring voltage, wrap tin foil around the top of the neg-

ative probe. Then press the foil against the wire with your finger.

2. Attach probe circuit tester (in Volt range) to middle portion of

each filament.

3. If a filament is burned out, circuit tester registers 0 or battery

voltage.

4. To locate burned out point, move probe to left and right along fil-

ament. Test needle will swing abruptly when probe passes the

• Ruler 30 cm (11.8 in) long

• Drawing pen

• Heat gun

• Alcohol

• Cloth

REPAIRING PROCEDURE

1. Wipe broken heat wire and its surrounding area clean with a

cloth dampened in alcohol.

2. Apply a small amount of conductive silver composition to tip of

drawing pen.

Shake silver composition container before use.

3. Place ruler on glass along broken line. Deposit conductive silver

composition on break with drawing pen. Slightly overlap existing

heat wire on both sides [preferably 5 mm (0.20 in)] of the break.

4. After repair has been completed, check repaired wire for conti-

nuity. This check should be conducted 10 minutes after silver

composition is deposited.

Do not touch repaired area while test is being conducted.

5. Apply a constant stream of hot air directly to the repaired area

for approximately 20 minutes with a heat gun. A minimum dis-

tance of 3 cm (1.2 in) should be kept between repaired area and

hot air outlet.

If a heat gun is not available, let the repaired area dry for 24

hours.
