Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), remote keyless entry system turns
on and off horn and headlamp intermittently with input of PANIC ALARM signal from keyfob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.
Keyless Power Window Down (Open) Operation
When keyfob unlock switch is turned ON with ignition switch OFF, and the switch is detected to be ON contin-
uously for more than 1 second, the driver's door and passenger's door power windows are simultaneously
opened.
Power window is operated to open and the operation continues as long as the keyfob unlock switch is
pressed.

Revision: November 2009 2006 QX56
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.
Retained power operation 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).
POWER WINDOW CONTROL BY THE FRONT DOOR LOCK ASSEMBLY LH (KEY CYLINDER
SWITCH)
When ignition key switch is OFF, front power window LH and RH can be opened or closed by turning the front
door lock assembly LH (key cylinder switch) to the UNLOCK/LOCK position for more than 1 second.

Front power windows can be opened as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the UNLOCK position.

Front power windows can be closed as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the LOCK position.

While performing open/close operation for the windows, power window is stopped when the front door
lock assembly LH (key cylinder switch) is placed in the NEUTRAL position.

When the ignition switch is turned ON while the power window opening operation is performed, the power
window opening stops.

Fuse EKS00GKH

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link EKS00GKI
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.

Never wrap outside of fusible link with vinyl tape.

Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00GKJ
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:

Power windows

Power door locks

Remote keyless entry system

Power sunroof

Rear window wiper
