Precaution for Supplemental Restraint S

PRE-TENSIONER"
INFOID:0000000001612909
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Trouble DiagnosisINFOID:0000000001328632
CAUTION:
Never apply 7.0 V or more to the measurement terminal.
Use a tester with open terminal voltage of 7.0 V or less.
Turn the ignition switch OFF and disconnect th e battery cable from the negative terminal when
checking the harness.
Precaution for Harness RepairINFOID:0000000001328633
Solder the repaired area and wrap tape around the soldered area. NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
Bypass connection is never allowed at the repaired area. NOTE:
Bypass connection may cause CAN communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.
Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica- tion line.
