through rear power vent window relay (OPEN) terminal 3

to rear power vent window motors terminal 1.
Ground is supplied

to rear power vent window relay (CLOSE) terminal 4

through rear power vent window relay (CLOSE) terminal 3

to rear power vent window motors terminal 2.
Then, the motors open the windows until the switch is released.
AUTO OPERATION
The power window AUTO feature enables the driver to open or close the window without holding the window
switch in the down or up position.
POWER WINDOW SERIAL LINK
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH, rear power
window control units and BCM transmit and receive the signal by power window serial link.
The signal is transmitted from BCM to main power window and door lock/unlock switch and power window and
door lock/unlock switch RH

Keyless power window down signal.

Rear power window switch illumination.
The signal is transmitted from main power window and door lock/unlock switch to power window and door
lock/unlock switch RH

Front door window RH operation signal.

Power window control by front door lock assembly LH (key cylinder switch) signal.

Power window lock signal.

Retained power operation signal.

Rear power window operation.
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 signal is transmitted to power window and door lock/unlock
switch RH by power window serial link. This prevents the power window motor 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

to main power window and door lock/unlock switch terminal 10

from BCM terminal 68.
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-II. Refer to GW-33, "
CONSULT-II Function (BCM)" .
ANTI-PINCH SYSTEM
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH and rear
power window control unit LH and RH 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 win-
dow motor.
When a 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
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH and rear
power window control unit LH and RH controls each power window motor for open and the power window will
be lowered about 150 mm (5.91 in).

Test Item Description
RETAINED PWRThis test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-II might be stuck if
“RETAINED PWR” is turned “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
