PRECAUTIONS PFP:00001 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” A EHS001Y8 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 Information necessary to service the system safely is included in the SRS 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 SRS 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 B C D E F Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service EHS001Y9 ● ● ● ● ● ● ● ● G 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 minutes For approximately minutes after the cables are removed, it is still possible for the air bag and seat belt SRS pre-tensioner to deploy Therefore, not work on any SRS connectors or wires until at least minutes have passed Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the I 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 attempt to J 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 place front side air bag module standing with stud bolt side setting bottom K 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 L Precautions for Trouble Diagnosis EHS001YA When you read wiring diagrams, refer to the following: ● GI-15, "How to Read Wiring Diagrams" in GI section ● PG-4, "POWER SUPPLY ROUTING CIRCUIT" in PG section When you perform trouble diagnosis, refer to the following: ● GI-11, "How to Follow Trouble Diagnoses" in GI section ● GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section Check for any service bulletins before servicing the vehicle SRS-3 M PREPARATION PREPARATION Special Service Tools PFP:00002 EHS001ZT Tool number Tool name

activated while the ignition switch is in the ON or START position The collision modes for which supplemental restraint systems are activated are different among the SRS systems For example, the driver air bag module, front passenger air bag module and front seat belt pre-tensioners are activated in a frontal collision but not in a side collision SRS configurations for some collision modes are as follows: SRS configuration Frontal collision Left side collision Right side collision Driver air bag module × — — Front passenger air bag module × — — Front LH seat belt pre-tensioner × — — Front RH seat belt pre-tensioner × — — Front LH side air bag module — × — Front RH side air bag module — — × LH side front curtain air bag module — × — LH side rear curtain air bag module — × — RH

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 EHS001XB A B C D WHIA0225E E

not use electrical test equipment on any circuit related to the SRS unless instructed to so in this Service Manual SRS wiring harnesses can be identified by yellow and/or orange harness connectors ● Do not attempt to repair, splice or modify SRS wiring harnesses If a harness is damaged, replace it with a new one ● Keep ground connections clean B C DIAGNOSIS FUNCTION D The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II The User mode is exclusively prepared for the customer (driver) This mode warns the driver of a system malfunction through the operation of the “AIR BAG” warning lamp The Diagnosis mode allows the technician to locate and inspect the malfunctioning part The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows: E User mode Diagnosis mode Display type “AIR BAG” warning lamp X X ON-OFF operation CONSULT-II — X Monitoring HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR F G A good
