• 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 harness 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 tion ON or engine running, DO NOT use air or electric 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.

Igni-• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

• 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 utes.

min-For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt tensioner to deploy Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

pre-• Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the vehicle for proper operation Also check 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 turn steering wheel and 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.

• Always replace instrument panel pad following front passenger air bag deployment.

• Replace occupant classification system control unit, system sensors, and passenger front seat frame as an assembly.

Refer to SE-18, "Removal and Installation"

the connector.

• After installing the connector, check that the lock is

pushed securely into it.

6 Remove the driver air bag module.

CAUTION:

• To prevent accidental explosion, always place the driver air

bag module with pad side facing upward.

Trang 6

• To prevent damage to the parts, never impact the driver air

• To prevent accidental explosion, never disassemble the driver air bag module.

• To prevent accidental explosion, never expose the driver air bag module to temperatures exceeding

• Connect the driver air bag module harnesses (A) and route

through the hook (B) as shown.

• do not damage the harness while installing.

• If malfunction is detected by the air bag warning lamp, after repair or replacement of the tioning parts, reset the memory using self-diagnosis or CONSULT Refer to SRC-13, "SRS Operation Check"

malfunc-• After the work is completed, check that no system malfunction is detected by air bag warning lamp.

• The spiral cable may snap during steering operation if the

cable is installed in an improper position.

The neutral position is set as follows.

• Carefully turn the spiral cable clockwise to the end position.

Then turn it counterclockwise (about two and a half turns) and

stop turning at the mark (B) where the stopper insertion holes

are in the same position.

stopper and can be set without adjusting after the stopper is

removed.

• Never over turn the spiral cable or go beyond the number of

turns required (This will cause the cable to snap)

• Carefully align the spiral cable locating pin (A) to the steering
