PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005981117
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 AIR BAG” and
“SEAT BELT” of this Service Instruction.
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 AIR BAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Instruction. 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition 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.

Description
BCM
Supplies power supply to power window switch.
Power window main switch
• Directly controls all power window motor of all doors.
• Controls anti-pinch operation of power window.
Front power window switch (passenger side)
Controls power window motor of front passenger side door.
Rear power window switch (LH & RH)
Controls power window motor of rear right and left doors.
Front power window motor (driver side)
• Integrates the encoder and power window motor.
• Starts operating with signals from power window main switch.
• Transmits front power window motor (driver side) rotation as a pulse signal to
power window main switch.
Front power window motor (passenger side)
Starts operating with signals from power window main switch & front power win-
dow switch (passenger side).
Rear power window motor (LH & RH)
Starts operating with signals from power window main switch & rear power window
switch (LH & RH).
Encoder
Detects condition of the front power window motor (driver side) operation and
transmits to power window main switch as pulse signal.

POWER WINDOW SYSTEM : System Description
INFOID:0000000005978505
POWER WINDOW OPERATION
• Power window main switch can open/close all windows.
• Front & rear power window switch can open/close the corresponding windows.
POWER WINDOW AUTO-OPERATION (FRONT DRIVER SIDE)
• AUTO UP/DOWN operation can be performed when power window main switch turns to AUTO.
• Encoder continues detecting the movement of power window motor and transmits to power window switch
as the encoder pulse signal while power window motor is operating.
• Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at
fully opened/closed position.
• Power window motor is operable in case encoder is malfunctioning.
POWER WINDOW LOCK
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window main switch.
ANTI-PINCH SYSTEM (FRONT DRIVER SIDE)
• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low-
ers the door glass 150 mm (5.9 in) when detected.
• Encoder continues detecting the movement of front power window motor (driver side) and transmits to
power window main switch as the encoder pulse signal while front power window motor (driver side) is oper-
ating.
• Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of
encoder pulse signal if foreign material is trapped in the door glass.
• Power window main switch controls to lower the window glass for 150 mm (5.9 in) after it detects encoder
pulse signal frequency change.
