POWER WINDOW SYSTEM

POWER WINDOW OPERATION

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

and OFF.

• Main power window and door lock/unlock switch can open/close all windows.

• Front & rear power window switch can open/close the corresponding windows.

POWER WINDOW AUTO-OPERATION (FRONT DRIVER SIDE & PASSENGER SIDE)

• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch &

power window and door lock/unlock switch RH 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.

• When timer time passes. (45 seconds)

POWER WINDOW LOCK

Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock

switch is ON. This inhibits power window switch operation except with the main power window and door lock/

unlock switch.

ANTI-PINCH OPERATION (FRONT DRIVER SIDE & PASSENGER 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 (5.91 in) 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 second 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 CONDITION 

• Ignition switch OFF.

• Hold door key cylinder to LOCK position for 1 second or more to perform CLOSE operation of the door

glass.

• Hold door key cylinder to UNLOCK position for 1 second or more to perform OPEN operation of the door

glass.

KEYLESS POWER WINDOW DOWN OPERATION (FRONT DRIVER SIDE & PASSENGER SIDE)

All power windows open when the unlock button on Intelligent Key is activated and kept pressed for more than
3 seconds

NOTE

 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 is active, 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 

BCS-24, "INTELLIGENT KEY : CONSULT Function (BCM - INTELLIGENT KEY)"

.

NOTE:

Use CONSULT to change settings.

MODE 1 (3 sec) / MODE 2 (OFF) / MODE 3 (5 sec)
