System Description

POWER WINDOW SYSTEM

• Power window system is operable during the retained power operation timer after turning ignition switch

OFF.

• Power window main switch can open/close door glass.
• Front and rear power window switch can open/close the corresponding door glass.
• AUTO UP/DOWN operation can be performed when front power window switch turns to AUTO.
• Power window lock switch can lock all power windows other than driver seat.
• Power window serial link transmits the signals from power window main switch to front power window switch

(passenger side).

• If door glass receives resistance that is the specified value or more while power window of front seat is in

AUTO-UP operation, power window of front seat operates in the reverse direction.

• Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5seconds or more to OPEN or CLOSE

from power window when ignition switch OFF.

• Front power windows open when pressing Intelligent Key unlock button for 3 seconds.

POWER WINDOW AUTO-OPERATION

• AUTO UP/DOWN operation can be performed when front power window motor turns to AUTO.
• Encoder continues detecting the movement of power window motor and transmits to power window switch

as the encoder pulse signal while power window motor is operating.

• Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at

fully opened/closed position.

• Power window motor is operable in case encoder is malfunctioning.

RETAINED POWER OPERATION

JMKIA1829GB

PWC-8

< SYSTEM DESCRIPTION >

POWER WINDOW SYSTEM

Retained power operation is an additional power supply function that enables power window system to oper-
ate for 45 seconds after ignition switch turns OFF.

RETAINED POWER FUNCTION CANCEL CONDITIONS

• Front door CLOSE (door switch OFF) 

→

 OPEN (door switch ON).

• When ignition switch turns ON again.
• When timer times out. (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.

POWER WINDOW SERIAL LINK

• Front power window switches and BCM transmit and receive the power window serial link.
• Power window serial link transmits the power window main switch operation signals and IGN signal to power

window main switch module, front power window switch (passenger side) module.

ANTI-PINCH OPERATION

• Pinch the foreign matter in the door glass during AUTO-UP operation is the anti-pinch function that lowers

the door glass 150 mm (5.9 in) when detected.

• Encoder continues detecting the movement of power window motor and transmits to power window switch

as the encoder pulse signal while power window motor is operating.

• Resistance is applied to the power window motor rotation 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 front 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 POWER WINDOW FUNCTION

Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5 seconds or more to OPEN or CLOSE-
front power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEU-
TRALwhen operating.
OPERATION CONDITION
• Ignition switch OFF.
• Hold door key cylinder to LOCK position for 1.5 seconds or more to perform CLOSE operation of the door

glass.

• Hold door key cylinder to UNLOCK position for 1.5 seconds or more to perform OPEN operation of the door

glass.

KEYLESS POWER WINDOW DOWN FUNCTION

Front 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 windows 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.
Keyless power window down operation mode can be changed by “PW DOWN SET” mode in “WORK SUP-
PORT”. Refer to 

DLK-56, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

.

NOTE:
Use CONSULT-III to change settings.
MODE 1 (3 sec) / MODE 2 (OFF) / MODE 3 (5 sec)
