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 Function (BCM)". Work Support (BCM)

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 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 front power window 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 each power window 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 power window motor.

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 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.

- When the ignition switch is turned ON while the power window DOWN is operated.

CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
