- from BCM terminal 53.

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 driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to "CONSULT-II Inspection Procedure" .

ANTI-PINCH SYSTEM

With front left and right power window anti-pinch system
Power window main switch and power window sub-switch (passenger side) monitors the power window motor operation and the power window position (full closed or other) for driver side and passenger side power window by the signals from encoder and limit switch in front power window motor (driver side and passenger side).

When power window main switch detects interruption during the following close operation,
- automatic close operation when ignition switch is in the "ON" position
- automatic close operation during retained power operation
- manual close operation during retained power operation

power window main switch or power window sub-switch (passenger side) controls each power window motor for open and the power window will be lowered about 150 mm (5.91 in).

With front and rear power window anti-pinch system
Power window main switch and power window each sub-switch monitors the power window motor operation and the power window position (full closed or other) for each power window by the signals from encoder and limit switch in front power window motor.
When power window main switch detects interruption during the following close operation,
- automatic close operation when ignition switch is in the "ON" position
- automatic close operation during retained power operation
- manual close operation during retained power operation

Power window main switch or each power window sub-switch controls each power window motor for open and the power window will be lowered about 150 mm (5.91 in).

POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, front power window can be opened or closed by turning the front door key cylinder driver side UNLOCK / LOCK position more then 1.5 second over condition.
- Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
- Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.

The power window opening stops when the following operations are carried out.
