SRS AIR BAG SYSTEM

< SYSTEM DESCRIPTION >
zone sensor, or satellite sensor. Air bag module is composed of electric igniter (squib), filter, pyrotechnic material, and gas generating material. When air bag module receives a signal from air bag diagnosis sensor unit, air bag module ignites pyrotechnic material using electric igniter (squib) so that gas generating material generates high temperature nitrogen gas. The gas through filter activates air bag. At the same time, pre-tensioner seat belt receives power supply from air bag diagnosis sensor unit, gasgenerator is activated, and then gas is generated. Balls in pipe are moved according to generated gas pressure and strike pinion gear on ELR shaft. ELR shaft rotates and retracts seat belt. When diagnosis sensor unit detects a rollover of the vehicle, electric igniter (spuib) receives power supply, pyrotechnic material is ignited, and then piston is projected. Piston rotates lever and lever rotation releases stopper. When stopper is released, pop-up roll bar is deployed by spring force.

AIR BAG DIAGNOSIS SENSOR UNIT FUNCTIONS
Air bag diagnosis sensor unit has the following functions. · Detects a collision and supplies the energy for deploying air bag and seat belt pre-tensioner. · Detects and records electrical malfunction in air bag system and seat belt pre-tensioner system, and blinking
air bag warning lamp. · Detects and records the deployment of air bag and seat belt pre-tensioner, and turns ON air bag warning
lamp. · Indicates malfunctioning portion via the number of blinks from the air bag warning lamp in the diagnosis
mode. · Indicates the malfunction record via CONSULT-III. · Suppresses the deployment of passenger air bag when passenger seat is empty or occupied by child or
child-seat. · When passenger seat is occupied by child or child seat, turns ON passenger air bag OFF indicator. · When judges that passenger seat is occupied by a adult or a child and passenger seat belt is not fasten,
turns ON seat belt warning lamp. Further information for the seat belt warning system, refer to SBC-9, "System Description".

COLLISION MODES
The operation of SRS is different depending on the collision modes applications. For example, the driver air bag module, passenger air bag module, and seat belt pre-tensioner are activated in a frontal collision but not in a side collision.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT

PRE-TENSIONER"

INFOID:0000000005153076

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 AIR BAG" and "SEAT BELT" 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 that 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 "SRS AIR BAG". · 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition 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. · 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.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000005153077

WARNING: · Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll
over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative, all maintenance must be performed by a NISSAN or INFINITI dealer. · Before removing and installing the pop-up roll bar component parts and harness, always turn the ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply circuit in the air bag diagnosis sensor unit.) · When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS AIR BAG CONTROL warnings in the Service Manual.

Service

INFOID:0000000004922160

· Never use electrical test equipment to check SRS circuits unless instructed to in this Service Manual. · Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes
or more. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pretensioner to deploy. Therefore, never work on any SRS connectors or wires until at least 3 minutes have passed. · 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. Never turn steering wheel and column after removal of steering gear.

Revision: 2010 March

SRC-208

2009 G37 Convertible

PRECAUTIONS

< PRECAUTION >

· 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. · Never solder the harness when making repairs. Check that harness is not pinched and that there is no con-

tact with other components.

· Never allow harness to come in contact with oil, grease, waste oil, or water.

· Never insert foreign materials, such as a screwdriver, into the harness connector. (This is to prevent acci- C

dental activation caused by static electricity.)

· Always use CONSULT-III or SRS air bag warning lamp to perform the circuit diagnosis. (Never use an elec-

tric tester such as a circuit tester.) · Never enter in the deployment area of the pop-up roll bar. Never put an object in the deployment area of the

pop-up roll bar. (This is to prevent injury in case of an unintentional deployment.)

· When handling a pop-up roll bar, always grip the frame and handle carefully.

· Never reuse a pop-up roll bar that has previously deployed.

· Modification of the pop-up roll bar may cause unintentional deployment or a malfunction. Never disassemble

or modify the pop-up roll bar.

· Never allow the pop-up roll bar to be impacted (by dropping or otherwise). Always replace the pop-up roll bar if impacted.

· When repairing the surrounding area of the pop-up roll bar, be careful not to apply excessive heat when

welding or otherwise. Remove the pop-up roll bar in advance, if necessary. Be careful when modifying the

mounting area or installing other parts because an incorrect procedure may cause damage or a malfunction. G

· Never disassemble the pop-up roll bar.

· Never expose the pop-up roll bar to temperatures exceeding 90 °C (194 °F).

· Never allow oil, grease, detergent, or water to come in contact with the pop-up roll bar.
