2. Turn ignition switch ON.

3. Operate power window switch to fully open the window. (This operation is unnecessary if the window is

already fully open)

4. Continue pulling the power window switch UP (AUTO-UP operation). Even after glass stops at fully closed

position, keep pulling the switch for 4 seconds or more.

5. Inspect anti-pinch function.

CHECK ANTI-PINCH FUNCTION

1. Fully open the door window.

2. Place a piece of wood near fully closed position.

3. Close door glass completely with AUTO-UP.

• Check that glass lowers for approximately 150 mm or 2 seconds without pinching piece of wood and stops.

• Check that glass does not rise when operating the main power window and door lock/unlock switch while

lowering.

CAUTION:

• Do not check with hands and other part of body because they may be pinched. Do not get pinched.

• Check that AUTO-UP operates before inspection when system initialization is performed.

• It may switch to fail-safe mode if open/close operation is performed continuously. Perform initial set-

ting in that situation. Refer to

PWC-229, "Fail Safe"

.

• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.

• Finish initial setting. Otherwise, next operation cannot be done.

1. Auto-up operation

2. Anti-pinch function

3. Retained power operation when ignition switch is OFF.

POWER WINDOW OPERATION

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

and OFF.

• Main power window and door lock/unlock switch can open/close all windows.

• Power window and door lock unlock switch RH can open/close the corresponding window.

POWER WINDOW AUTO-OPERATION (LH & RH)

• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch &

power window and door lock/unlock switch RH 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

• 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

• Door CLOSE (door switch OFF)

→OPEN (door switch ON).

• When ignition switch is ON.

• When timer time passes. (45 seconds)

POWER WINDOW LOCK

Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock

switch is ON. This inhibits power window switch operation except with the main power window and door lock/

unlock switch.

ANTI-PINCH OPERATION (LH & RH)

• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low-

ers the door glass 150 mm or 2 seconds 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 window glass for 150 mm or 2 seconds after it detects encoder

pulse signal 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.

KEY CYLINDER SWITCH OPERATION

Hold the door key cylinder to the LOCK or UNLOCK direction for more than 1 second to OPEN or CLOSE front

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 more than 1 second to perform CLOSE operation of the door

glass.

POWER WINDOW SYSTEM

• Hold door key cylinder to UNLOCK position for more than 1 second to perform OPEN operation of the door

glass.

KEYLESS POWER WINDOW DOWN OPERATION (LH & RH)

Front power windows open when the unlock button on Intelligent Key is activated and kept pressed for more
than 3

(NOTE)

seconds with the ignition switch OFF. The windows keep opening if the unlock button is continu-

ously 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.

NOTE:

Keyless power window down operation mode can be changed by “PW DOWN SET” mode in “WORK SUP-

PORT”. Refer to

BCS-18, "COMMON ITEM : CONSULT-III Function"

.

NOTE:

Use CONSULT-III to change settings.

MODE 1 (3sec) / MODE 2 (OFF) / MODE 3 (5sec)
