• Encoder continues detecting the movement of power window motor and transmits to main power window

and door lock/unlock switch as the encoder pulse signal while power window motor is operating.

• Main power window and door lock/unlock switch reads the changes of encoder signal and stops AUTO oper-

ation 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 

• 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 (LH)

• 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 or 2 seconds when detected.

• Encoder continues detecting the movement of power window motor and transmits to main power window

and door lock/unlock 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 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.

Function

BCM

• Supplies power to power window switches.
• Controls retained power.

Main power window and door lock/un-
lock switch

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

Power window and door lock/unlock 
switch RH

• Controls power window motor RH.

Power window motor LH

• Integrates the ENCODER POWER and WINDOW MOTOR.
• Starts operating with signals from main power window and door lock/unlock switch.
• Transmits power window motor rotation as a pulse signal to main power window and 

door lock/unlock switch.

Power window motor RH

Starts operating with signals from main power window and door lock/unlock switch & 
power window and door lock/unlock switch RH.

Door switch LH or RH

Detects door open/close condition and transmits to BCM.
