PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000010296082

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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion 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 three minutes before performing any service.
Precaution for Work INFOID:0000000009757208

• When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component
with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty
area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

POWER WINDOW OPERATION

• Power window system is activated by the power window switch when the ignition switch is in the ON position
or during the retained power operation after ignition switch is turned OFF.
• Main power window and door lock/unlock switch can open/close all windows.
• Front & rear power window switches can open/close the corresponding windows.
• Power window lock switch can lock all power windows other than driver seat.
• If door glass receives resistance that is more than the specified value and the power window is in the AUTO-
UP operation (Front LH), power window will move in the reverse direction (Anti-Pinch Function).
POWER WINDOW AUTO-OPERATION (FRONT LH)
Revision: October 2013 PWC-8 2014 Sentra NAM
SYSTEM
< SYSTEM DESCRIPTION >
• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch turns
to AUTO. A
• Encoder continues detecting the movement of power window motor and transmits to main power window
and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Main power window and door lock/unlock switch reads the changes of encoder signal and stops AUTO oper-
B
ation when door glass is at fully opened/closed position.
• Power window motor is operable in case encoder is malfunctioning.
RETAINED POWER OPERATION C
• Retained power operation is an additional power supply function that enables power window system to oper-
ate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions D
• Front door CLOSE (door switch OFF)→OPEN (door switch ON).
• When ignition switch is ON.
• When timer time passes. (45 seconds)
E
• AUTO function does not operate if encoder is malfunctioning.
POWER WINDOW LOCK FUNCTION
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock F
switch is ON. This inhibits power window switch operation except with the main power window and door lock/
unlock switch.
ANTI-PINCH OPERATION (FRONT LH) G
• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low-
ers the door glass 150mm. (5.9 in.) or 2 seconds when detected.
• Encoder continues detecting the movement of power window motor and transmits to main power window
H
and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
• Power window switch controls to lower the window glass form 150mm (5.9 in.) or 2 seconds after it detects I
encoder pulse signal frequency change.
OPERATION CONDITION
• When door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the door J
glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower. PWC

< SYSTEM DESCRIPTION >
It changes to condition before initialization and the following functions do not operate when switched to fail-
safe control:
• Auto-up operation
• Anti-pinch function
• Retained power function

Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or in motor.
