POWER WINDOW SUB-SWITCH OPERATION
WINDOW UP
When the power window sub-switch is pressed in the up position
Power is supplied

●

through power window sub-switch terminal 8.

●

to passenger side power window motor terminal 2

Ground is supplied

●

to passenger side power window motor terminal 1

●

through power window sub-switch terminal 9.

Then, the motor raises the window until the switch is released.
WINDOW DOWN 
When the power window sub-switch is pressed in the down position
Power is supplied

●

through power window sub-switch terminal 9.

●

to passenger side power window motor terminal 1

Ground is supplied

●

to passenger side power window motor terminal 2

●

through power window sub-switch terminal 8.

Then, the motor lowers the window until the switch is released.
POWER WINDOW MAIN SWITCH OPERATION
Signal is sent

●

though power window main switch terminal 12.

●

to power window sub-switch terminal 16

The operation of power window after receiving the signal is as same as for operating the power window with
sub-switch.

POWER WINDOW SERIAL LINK

Power window main switch, power window sub-switch and BCM transmit and receive the signal by power win-
dow serial link.
The under mentioned signal is transmitted from BCM to power window main switch.

●

Driver side door switch signal.

●

Keyless power window down signal.

The under mentioned signal is transmitted from BCM to power window sub-switch.

●

Passenger side door switch signal.

●

Keyless power window down signal.

The under mentioned signal is transmitted from power window main switch to power window sub-switch 

●

Passenger side door window operation signal.

●

Power window control by key cylinder switch signal.

●

Power window lock signal.

AUTO OPERATION

The power window AUTO feature enables the driver to open or close the window without holding the window
switch in the down or up position.

POWER WINDOW LOCK

The power window lock is designed to lock operation of passenger side door window.
When the lock position, power window lock signal is sent by using power window serial link from power win-
dow main switch to power window sub-switch.
Power window sub-switch by which the signal is received, prohibits the operation of passenger side power
window by power window sub-switch.

POWER WINDOW SYSTEM

RETAINED POWER OPERATION

When the ignition switch is turned to the OFF position from ON or START position.
 Power is supplied for 45 seconds

●

from BCM terminal 53.

●

to power window main switch terminal 10.

Then the power window can be operated.
The retained power operation is canceled when the driver side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to 

GW-30, "WORK SUPPORT"

 .

ANTI-PINCH SYSTEM

Power window main switch and power window sub-switch monitors the power window motor operation and the
power window position (full closed or other) for driver side and passenger side power window by the signals
from encoder and limit switch in power window motor (driver side and passenger side).
When power window main 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

●

manual close operation during retained power operation

power window main switch or power window sub-switch 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 KEY CYLINDER SWITCH

When ignition key switch is OFF, power window can be opened or closed by turning the door key cylinder
UNLOCK / LOCK position more then 1.5 second over condition.

●

Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.

●

Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.

The power window control operation by the key cylinder switch stops when the following operations are car-
ried out.

●

While performing open / close the window, power window is stopped at the position as the door key cylin-
der is placed on NEUTRAL.

●

When the ignition switch is turned ON while the power window control operation by the key cylinder switch
is operated.

AUTOMATIC WINDOW ADJUSTING FUNCTION

When the driver's / passenger's door(s) is opened, the window of the opened door is lowered approx. 10 mm
(0.39in).
When the door is closed, the window is raised to fully-closed positions.
Automatic window adjusting function system (opening operation) does not operate when the following.

●

The window is 10 mm (0.39 in) or more open from fully-closed positions.

Automatic window adjusting function system (closing operation) does not operate when the following.

●

The automatic window adjusting function system (opening operation) operation.

●

The keyless power window operation.

●

The power window control by the key cylinder switch operation.

CAN Communication System Description

NIS000E9

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
