Power Window Control System (Front Window Anti-Pinch): Overview Nissan Quest IV

DESCRIPTION

1. Power window system is activated by power window switch when ignition switch turns ON, or during the retained power operation after ignition switch turns OFF.
2. Power window main switch opens/closes all door glass.
3. Front and sliding door power window switch opens/closes the corresponding door glass.
4. AUTO UP/DOWN operation can be performed when power window main switch or front power window switch (passenger side) turns to AUTO.
5. Power window serial link transmits the signals from power window main switch to front power window switch (passenger side).
6. Power window lock switch can lock all power windows other than driver seat.
7. If door glass receives resistance that is the specified value or more while power window of front seat is in AUTO-UP operation, power window of front seat operates in the reverse direction.
8. Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5 seconds or more to OPEN or CLOSE front power windows when ignition switch OFF.
9. Front power windows open when pressing Intelligent Key unlock button for 3 seconds.

Power Window AUTO-Operation

1. AUTO UP/DOWN operation can be performed when power window main switch or front power window switch (passenger side) turns to AUTO.
2. Encoder continues detecting the movement of power window motor and transmits the encoder pulse signal to power window switch while power window motor is operating.
3. Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at the fully opened/closed position.
4. Power window motor is operable if encoder is malfunctioning.

Retained Power Operation

Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF.

ANTI-PINCH Operation

1. Pinch foreign matter in the door glass during AUTO-UP operation, and it is the ANTI-PINCH function that lowers the door glass 150 mm (5.9 in) or for 2 seconds when detected.
2. 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.
3. Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass.
4. Power window switch controls to lower the door glass for 150 mm (5.9 in) after it detects encoder pulse signal frequency change.

Operation Condition

When front 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.

Door 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 front power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL when operating.

Operation Conditions

1. Ignition switch OFF.
2. Hold door key cylinder to LOCK position for 1.5 seconds or more to perform CLOSE operation of the door glass.
3. 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 Operation

Front 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.

1. When the unlock button is kept pressed more than 15 seconds.
2. When the ignition switch is turned ON while the power window opening is operated.
3. 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 SUPPORT". Refer to " INTELLIGENT KEY: CONSULT FUNCTION (BCM - INTELLIGENT KEY) ".
