AUTO OPERATION
The power window AUTO feature enables the driver to open or close the front door window LH without holding the window switch in the up or down position.

POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for front door window LH.
When in the lock position, the power window lock disables power window and door lock/unlock switch RH and rear power window switch LH and RH by disconnecting switch ground signal. This prevents the power window motors from operating.

RETAINED POWER OPERATION
When the ignition switch is turned to the OFF position from ON or START position, power is supplied
- through BCM terminal 68
- to main power window and door lock/unlock switch terminal 5
- to power window and door lock/unlock switch RH terminal 8
- to rear power window switches LH and RH terminal 8.
When power and ground are supplied, the BCM continues to be energized, and the power window can be operated.
The retained power operation is canceled when the front LH or front RH door is opened.
RAP signal period can be changed by CONSULT-III.

ANTI-PINCH SYSTEM
The main power window and door lock/unlock switch monitors the power window motor operation and the power window position (fully closed or other) for the front LH power window. The switch monitors signals from the encoder and limit switch in the front power window motor LH.
When the main power window and door lock/unlock switch detects an interruption other than the fully closed signal during the automatic close operation, either with the ignition switch in the ON position, or during retained accessory power operation, the main power window and door lock/unlock switch will automatically lower the front LH power window.
