Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSION-
ER"
INFOID:0000000001728318
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 SR 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 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.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716758
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 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 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 har-
ness connectors.

System DescriptionINFOID:0000000001366593
OUTLINE
The front wiper is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
Front wiper control function
Control by IPDM E/R
Front wiper control function
Relay control function
FRONT WIPER BASIC OPERATION
BCM detects the combination switch condition by the combination switch reading function.
BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.
FRONT WIPER LO OPERATION
BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
front wiper LO operating condition.
Front wiper LO operating condition
- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the
front wiper HI operating condition.
Front wiper HI operating condition
- Ignition switch ON
- Front wiper switch HI
IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper
request signal (HI).
