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 Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har- ness 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 Igni- 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. • 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. Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service INFOID:0000000007605423 • 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 bag and seat belt pre- tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed. • The air bag 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.

Component Function AWHIA0319ZZ AWHIA0320ZZ AWHIA0333ZZ Revision: July 2011 2012 Versa Sedan SRC-6 < SYSTEM DESCRIPTION > COMPONENT PARTS Vehicles with side curtain air bags are equipped with labels on the center pillar upper finisher as shown. Front Seat Belt Pre-tensioner INFOID:0000000007605430 The seat belt pre-tensioner system with load limiter is installed for both the driver's seat and the front passenger's seat. It operates simultaneously with the SRS air bag system in the event of a frontal collision with an impact exceeding a specified level. When the frontal collision with an impact exceeding a specified level occurs, seat belt slack resulting from clothing or other factors is immediately taken up by the pre-tensioner. Vehicle passengers are securely restrained. When passengers in a vehicle are thrown forward in a collision and the restraining force of the seat belt exceeds a specified level, the load limiter permits the specified extension of the seat belt by the twisting of the ELR shaft, and a relaxation of the chest-area seat belt web tension while maintaining force. Air Bag Diagnosis Sensor Unit INFOID:0000000007605431 The air bag diagnosis sensor unit is located under the center con- sole. The air bag diagnosis sensor unit receives signals from multi- ple SRS sensors and controls the deployment of the air bags. The deployment of the air bags depends on the type and severity of the collision. The air bag diagnosis sensor unit has self-diagnosis capa- bility through the use of the CONSULT as well as flash codes dis- played by the air bag warning lamp. Crash Zone Sensor INFOID:0000000007605432 The crash zone sensor is located behind the front grille in front of the radiator support. The crash zone sensor sends signals to the air bag diagnosis sensor unit during a frontal collision. This sensor may be identified by a yellow connector.

The OCS control unit (2) receives inputs from the occupant classification sensors (1) (located inside the passenger seat cushion assembly). Depending on clas- sification of the passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit uses this signal and the seat belt buckle switch RH signal to determine deployment or non deploy- ment of the passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis sensor unit can disable the passenger front air bag completely. The OCS (weight sensors) must be set to zero point using CONSULT after servicing the OCS system. NOTE: • CONSULT can be used to confirm when “zero point reset” for OCS is complete. • Always perform zero point reset after the removal and installation of the seat or when disconnecting the OCS control unit harness connector even if zero point reset has been completed in the past. • If zero point reset is incomplete, the passenger air bag will be disabled and the passenger air bag off indica- tor will be ON. • In case of customer concern, CONSULT can be used to confirm the passenger air bag status (readiness).
