POWER WINDOW SYSTEM
The one is applied only for front doors and the other is for all doors.
POWER WINDOW SERIAL LINK
Power window main switch, front power window switch (passenger side), and BCM transmit and receive the
signal by power window serial link.
The under mentioned signal is transmitted from BCM to power window main switch and front power window
switch (passenger side)
 Keyless power window down signal.
The under mentioned signal is transmitted from power window main switch to front power window switch (pas-
senger side)
 Front passenger side door window operation signal.
 Power window control by key cylinder switch signal.
 Power window lock signal.
 Retained power operation signal.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for driver side door window.
When the lock position, ground of the rear power window switches in the power window main switch is discon-
nected. The power window lock signal is transmitted to front power window switch (passenger side) by power
window serial link. This prevents t he power window motors 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
 through BCM terminal 53
 to power window main switch terminal 10
 to rear power window switch (LH and RH) terminals 1.
When power and ground are supplied, the BCM conti nues to be energized, and the power window can be
operated.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-III. Refer to GW-26, "
CONSULT-III Function".
ANTI-PINCH SYSTEM
Power window main switch and front power window switch (passenger side) monitors the power window motor
operation and the power window position (full closed or other) for driver side and passenger side power win-
dow by the signals from encoder and limit switch in front power window motor (driver side and passenger
side).
When power window main switch detects inte rruption during the following close operation,
 automatic close operation when igniti on 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 front power window swit ch (passenger side) 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, front power window can be opened or closed by turning the key cylinder
switch UNLOCK / LOCK position more than 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 DOWN stops when the following operations are carried out.
 While performing open / close the window, power window is stopped at the position as the door key cylinder is placed on NEUTRAL.
 When the ignition switch is turned ON while the power window DOWN is operated.
CAN Communication System DescriptionINFOID:0000000001327964
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 s peed 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 CA N 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.
