Then, the motor raises the window until the switch is released.
WINDOW DOWN
When the main power window and door lock/unlock switch (rear LH) is pressed in the down position, power is
supplied
• through main power window and door lock/unlock switch terminal 3
• to rear power window switch LH terminal 3
• through rear power window switch LH terminal 4
• to rear power window motor LH terminal 1.
Ground is supplied
• through main power window and door lock/unlock switch terminal 1
• to rear power window switch LH terminal 2
• through rear power window switch LH terminal 5
• to rear power window motor LH terminal 2.
Then, the motor lowers the window until the switch is released.
When the main power window and door lock/unlock switch (rear RH) is pressed in the down position, power is
supplied
• through main power window and door lock/unlock switch terminal 5
• to rear power window switch RH terminal 3
• through rear power window switch RH terminal 4
• to rear power window motor RH terminal 1.
Ground is supplied
• through main power window and door lock/unlock switch terminal 7
• to rear power window switch RH terminal 2
• through rear power window switch RH terminal 5
• to rear power window motor RH terminal 2.
Then, the motor lowers the window until the switch is released.
AUTO OPERATION
The power window AUTO feature enables the driver to open the window without holding the window switch in
the 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 for 45
seconds
• through BCM terminal 68
• to main power window and door lock/unlock switch terminal 10
• to power window and door lock/unlock switch RH terminal 8 and
• to rear power window switches LH and RH terminal 1.
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.
Retained power operation period can be changed by CONSULT-III. Refer to GW-28, "
CONSULT-III Function
(BCM)" .
ANTI-PINCH SYSTEM
Main power window and door lock/unlock switch monitors the power window motor operation and the power
window position (full closed or other) for front LH power window by the signal from encoder in front power win-
dow motor LH.
When main power window and door lock/unlock switch detects interruption during the following close opera-
tions
• 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 controls front power window motor LH for open and the
power window will be lowered.

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-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-III screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RE-
TAINED PWR” is turned “ON” or “OFF” on CONSULT-III screen when ignition switch is OFF.
