POWER WINDOW OPERATION

• 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 (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 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.

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 OPERATION (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 150mm or 2 seconds when detected.

• Encoder continues detecting the movement of front power window motor (driver side) and transmits to

power window main switch as the encoder pulse signal while front power window motor (driver side) is oper-
ating.

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

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

• Power window main switch controls to lower the window glass for 150mm or 2 seconds after it detects

encoder pulse 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.

Component

Function

BCM

• Supplies power supply to power window switch.
• Controls retained power.

Power window main switch

• Directly controls all power window motor of all doors.
• Controls anti-pinch operation of power window.

Front power window switch

Controls power window motor of front passenger side door.

Rear power window switch (LH & RH)

Controls power window motor of rear right and left doors.

Front power window motor (driver side)

• Integrates the encoder and power window motor.
• Starts operating with signals from power window main switch.
• Transmits front power window motor (driver side) rotation as a pulse signal to power

window main switch.

Front door window motor (passenger
side)

Starts operating with signals from power window main switch & front power window
switch (passenger side).

Rear power window motor (LH & RH)

Starts operating with signals from power window main switch & rear power window
switch (LH & RH).
