POWER WINDOW OPERATION 

• Power window system is activated by power window switch when ignition switch ON or retained power is operating.
• Main power window and door mirror switch opens/closes all door glass.
• Front and rear power window switch opens/closes the corresponding door glass.

POWER WINDOW AUTO-OPERATION 

• AUTO UP/DOWN operation can be performed when main power window and door mirror switch turns to AUTO.
• Main power window and door mirror switch transmits AUTO UP/DOWN signal to power window motors.
• Power window motors read the changes of operating condition and stops AUTO operation when door glass is at fully opened/closed position.

RETAINED POWER FUNCTION 

Retained power function is an additional power supply function that enables power window system to operate for 45 seconds after ignition switch turns OFF.

RETAINED POWER FUNCTION CANCEL CONDITIONS

Any of the following conditions are satisfied:

• Front door CLOSE → OPEN.
• When ignition switch is ON again.
• When timer times out. (45 seconds)

LIN COMMUNICATION 

Main power window and door mirror switch, power window motors, and BCM transmit and receive signal by LIN communication.

POWER WINDOW LOCK 

LIN circuit inside main power window and door mirror switch shuts off when power window lock switch is ON. This inhibits rear power window switch operation.

ANTI-PINCH SYSTEM 

• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass when detected.
• CPU continues detecting the movement of power window motors while power window motors are operating.
• Power window motors control to lower the door glass for approximately 145 mm (5.71 in) or more after it detects foreign material is trapped in the door glass.

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)
