“SEAT BELT PRE-TENSIONER” A EKS00N4A 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 Wiring Diagrams and Trouble Diagnosis When you read wiring diagrams, refer to the following: ● Refer to GI-15, "How to Read Wiring Diagrams" in GI section ● Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution When you perform trouble diagnosis, refer to the following: ● Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section ● Refer to GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section B C D E F EKS00LIU G H I J PG L M PG-3 POWER
