System Description

INFOID:0000000009159906

POWER WINDOW OPERATION

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

to OFF.

• Power window main switch can open/close all windows.
• Power window sub-switch can open/close the passenger side windows.

POWER WINDOW AUTO-OPERATION

• When each switch of power window main switch or assistant seat power window switch is operated to the

Auto position, power window motor is activated in the AUTO UP or DOWN operation.

• When the glass is in the fully open or close position, module in power window motor detects the encoder sig-

nal change and deactivates the AUTO UP or DOWN operation.

• Even if the encoder is malfunctioning, power window motor can be activated. (Except in AUTO operation.)

RETAINED POWER OPERATION 

BCM controls power window for approximately 45 seconds after ignition switch turns OFF. (In a position other
than ON)

Retained power function cancel conditions

When BCM detects the following signal it cancels.

1.

When any door is open.

2.

When ignition switch turns ON again.

3.

When timer time passes. (Approximately 45 seconds)

< SYSTEM DESCRIPTION >

POWER WINDOW SYSTEM

NOTE:
If the system initialization is not complete, the retained power operation does not operate.

POWER WINDOW LOCK FUNCTION

When power window lock switch turns ON, assistant seat power window switch circuit in power window main
switch shuts OFF and assistant seat power window switch is deactivated.

ANTI-PINCH FUNCTION

Module in driver seat and assistant seat power window motor detects and controls front door glass operation
via encoder signal 1 and encoder signal 2. While door glass is moving upward in AUTO UP or retained power
operation, when front door glass receives a load of the specified value or more, the module detects the
encoder signal change, stops power window motor AUTO UP operation, sends DOWN signal, and lowers the
front door glass for the specified value (approximately 150 mm).
OPERATION CONDITION
• When front door glass is between fully the open position and the position just before fully closed. When front

door glass is not fully closed.

• When front door glass is moving upward in the AUTO UP operation.
• When front door glass is moving upward in ignition switch position except ON (timer operation).
NOTE:
Anti-pitch function may be activated when a load or impact similar to pinching is applied on front door glass by
surrounding conditions or driving conditions.

AUTOMATIC WINDOW ADJUSTING FUNCTION

• When driver seat door or assistant seat door is open, the door glass of opened door lowers approximately 15

mm from the fully closed position. After the door is closed, it raises the door glass to the fully closed position.
This improves the operability for door open or close, and the sealing ability of door glass.

• Even if power window is in the lock position, the automatic window adjusting function operates.
• The open or closed door position is judged by the door switch position that is ON or OFF.
No operating conditions
• When the automatic window adjusting function starts to lower the door glass, the door glass is already open

the specified value (approximately 15 mm) or more from the fully closed position.

• When the automatic window adjusting function is lowering the door glass, the door is closed.
