Qashqai J11. Power window control system — part 1

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 Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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.

Precautions for Removing Battery Terminal

INFOID:0000000010503265

• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key

or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.

• When disconnecting the 12V battery terminal, turn off the ACC

power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

HOW TO DISCONNECT 12V BATTERY TERMINAL

Disconnect 12V battery terminal according to instruction described below.
1.

Open the hood.

Turn ignition switch to the ON position.

Turn ignition switch to the OFF position with the driver side door opened.

Get out of the vehicle and close the driver side door.

PRECAUTIONS

PWC-5

< PRECAUTION >

PWC

Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

POWER WINDOW OPERATION

• BCM controls the power window relay, and controls the ignition ON power source supplied to each power

window switch.

• Power window system is activated by power window switch when ignition switch turns ON.
• Power window main switch opens/closes all door glass.
• Front and rear power window switch opens/closes the corresponding door glass.
• AUTO UP/DOWN operation can be performed when power window main switch turns to AUTO.
• Power window lock switch can lock all power windows other than driver seat.
• If door glass receives resistance that is the specified value or more while power window of driver seat is in

AUTO-UP operation, power window of driver seat operates in the reverse direction.

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 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 120 – 150 mm (4.7 – 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 signal while front power window motor (driver side) is operating.

• Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of

encoder signal if foreign material is trapped in the door glass.

SYSTEM

PWC-11

< SYSTEM DESCRIPTION >

PWC

• Power window main switch controls to lower the window glass for 120 – 150 mm (4.7 – 5.9 in) after it detects

encoder signal frequency change.

OPERATION CONDITION
• When front door glass (driver side) AUTO-UP operation is performed (anti-pinch function does not operate

just before the door 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.

Fail Safe

INFOID:0000000010286481

FAIL-SAFE CONTROL

Power window main switch to fail-safe control when malfunction is detected in encoder signal that detects up/
down speed and direction of door glass. Power window main switch to fail-safe control when error beyond reg-
ulation value is detected between the fully closed position and the actual position of the glass.

It changes to condition before initialization and the following functions do not operate when power window
main switch to fail-safe control.
• Auto-up operation
• Anti-pinch function

Perform initial operation to recover when power window main switch to fail-safe mode. However, it power win-
dow main switch back to fail-safe control when malfunction is found in power window main switch or front
power window motor (driver side).
