With front and rear power window anti-pinch system
The power window lock is designed to lock operation of all windows except for driver side door window. When the lock position, the power window lock signal is transmitted to front power window switch (passenger side) and rear power window switches by power window serial link. 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 for 45 seconds / with front power window anti-pinch system
- through BCM terminal 53
- to power window main switch terminal 10
- to rear power window switch (LH and RH) terminals 1.

Power is supplied for 45 seconds / with front and rear power window anti-pinch system
- through BCM terminal 53
- to power window main switch terminal 10.

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

When power window 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 switch controls each power window regulator 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 key cylinder switch UNLOCK / LOCK position more than 1.5 second over condition.
