Infiniti G35 (V35) Sedan. Manual - part 1044

PWC-8

< BASIC INSPECTION >

[FRONT & REAR WINDOW ANTI-PINCH]

INSPECTION AND ADJUSTMENT

2.

Turn ignition switch ON.

3.

Operate power window switch to fully open the window. (This operation is unnecessary if the window is
already fully open)

4.

Continue pulling the power window switch UP (AUTO-UP operation). Even after glass stops at fully closed
position, keep pulling the switch for 3 seconds or more. 

5.

Inspect anti-pinch function.

CHECK ANTI-PINCH FUNCTION

1.

Fully open the door window.

2.

Place a piece of wood near fully closed position.

3.

Close door glass completely with AUTO-UP.

• Check that glass lowers for approximately 150 mm or 2 seconds without pinching  piece of wood and stops.
• Check that glass does not rise when operating the power window main switch while lowering.

CAUTION:

• Do not check with hands and other part of body because they may be pinched.  Do not get pinched.
• Check that AUTO-UP operates before inspection when system initialization is performed.
•  It may switch to fail-safe mode if open/close operation is performed continuously. Perform initial

setting in that situation.  Refer to 

PWC-89, "Fail Safe"

• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.
• Finish initial setting. Otherwise, next operation cannot be done.

POWER WINDOW SYSTEM

POWER WINDOW OPERATION

• Power window system is operable during the retained power operation timer after turning ignition switch ON

and OFF.

• Power window main switch (driver side) can open/ close all windows.
• Front & rear power window switch can open/ close the corresponding windows.

POWER WINDOW AUTO-OPERATION

• AUTO UP/DOWN operation can be performed when each power window motor 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.

RETAINED POWER OPERATION 

• 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

• Front door CLOSE (door switch OFF)

→

OPEN (door switch ON).

• When ignition switch is ON again.
• When timer time passes. (45 seconds)

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 switch.

ANTI-PINCH OPERATION

• Pinch the foreign material in the door glass during AUTO-UP operation is the anti-pinch function that lowers

the door glass 150 mm or 2 seconds when detected.

• 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.

• 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 for 150 mm or 2 seconds after it detects encoder

pulse signal frequency change.

OPERATION CONDITION
• When all door glass 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.

KEY CYLINDER SWITCH OPERATION

Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5 seconds or more to OPEN or CLOSE all
power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL
when operating.
OPERATION CONDITION
• Ignition switch OFF.
• Hold door key cylinder to LOCK position for 1.5 seconds or more to perform CLOSE operation of the door

glass.

• Hold door key cylinder to UNLOCK position for 1.5 seconds or more to perform OPEN operation of the door

glass.

KEYLESS POWER WINDOW DOWN FUNCTION

All power windows open when the unlock button on Intelligent Key is activated and kept pressed for more than
3* seconds with the ignition switch OFF. The windows keep opening if the unlock button is continuously
pressed.
The power window opening stops when the following operations are performed.
• When the unlock button is kept pressed more than 15 seconds.
• When the ignition switch is turned ON while the power window opening is operated.
• When the unlock button is released.
While retained power operation activate, keyless power window down function cannot be operated.
Keyless power window down operation mode can be changed by “PW DOWN SET” mode in “WORK SUP-
PORT”. Refer to 

DLK-51, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

.

NOTE:
Use CONSULT-III to change settings.
MODE 1 (3sec) / MODE 2 (OFF) / MODE 3 (5sec)
