Component DescriptionINFOID:0000000006217265
Component Function
BCM  Supplies power supply to power window switch.
 Controls retained power.
Power window main switch  Directly controls all power window motor of all doors.
 Controls anti-pinch operation of power window.
Front power window switch
(passenger side)  Controls anti-pinch operation of power window.
 Controls power window motor of passenger door.
Rear power window switch  Controls anti-pinch operation of power window.
 Controls power window motor of rear right and left doors.
Power window motor  Integrates the ENCODER and WINDOW MOTOR.
 Starts operating with signals from each power window switch.
 Transmits power window motor rotation as a pulse signal to power window switch.
Remote keyless entry receiver Receives lock/unlock signal from the intelligent key, and then transmits to BCM.
Front door lock assembly (door key cyl-
inder switch) Transmits operation condition of door key cylinder switch to power window main switch.
Front door switch (driver side/passen-
ger side) Front door open/close condition and transmits to BCM.

The signal mentioned below is transmitted from BCM to power window main \
switch, front power window
switch (passenger side) and rear power window switch LH/RH.
 Keyless power window down signal
 Door switch signal
The signal mentioned below is transmitted from power window main switch to front power window switch (pas-
senger side) and rear power window switch LH/RH.
 Front passenger side door window and rear door window operation signal
 Power window control by door key cylinder switch signal
 Power window lock switch signal
 Retained power operation signal
RETAINED POWER OPERATION
 Retained power operation is an additional power supply function that enables power window system to oper-
ate during the 45 seconds even when ignition switch is turned OFF.
Retained Power Function Cancel Conditions
 Front door CLOSE (door switch OFF) →OPEN (door switch ON).
 When ignition switch is ON again.
 When timer time passes. (45 seconds)
POWER WINDOW LOCK FUNCTION
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window main switch.
ANTI-PINCH OPERATION
 Anti-pinch foreign lowers door glass 150 mm (5.9 in) when foreign material is pinched in door glass during
AUTO-UP operation.
 Encoder continues detecting the movement of power window motor and output the encoder pulse signal to
power window switch l while power window motor is operating.
 Resistance is applied to the power window motor ro tation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
 Power window switch controls to lower the door glass for 150 mm (5.9 in) after it detects encoder pulse sig-
nal frequency change.
Operation Condition
When all door glass AUTO-UP operation is performed ( anti-pinch function does not operate just before the
door glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower.
DOOR KEY CYLINDER SWITCH OPERATION
Hold the door key cylinder to the LOCK or UNLOCK direct ion for 1.5 seconds or more to OPEN or CLOSE all
power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL
when operating.
Operation Condition
 Ignition switch OFF.
 Hold door key cylinder to LOCK position for 1.5 se conds or more to perform CLOSE operation of the door
glass.
 Hold door key cylinder to UNLOCK position for 1.5 se conds or more to perform OPEN operation of the door
glass.
KEYLESS POWER WINDOW DOWN FUNCTION
All power windows open when the unlock button on Intelligent Key is activated and kept pressed for more than
3 seconds with the ignition switch OFF. The wi ndows keep opening if the unlock button is continuously
pressed.
The power window opening stops when the following operations are performed.
 When the unlock button is kept pressed more than 15 seconds.
 When the ignition switch is turned ON while the power window opening is operated.
 When the unlock button is released.
While retained power operation activate, keyless power window down function cannot be operated.
