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 SERIAL LINK
Power window main switch, any power window sub-switches 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 power window sub-
switches.

Keyless power window down signal.
The under mentioned signal is transmitted from power window main switch to power window sub-switch (front
passenger side)

Front passenger side door window operation signal.

Power window control by key cylinder switch signal.

Power window lock signal.

Retained power operation signal.
The under mentioned signal is transmitted from power window main switch to power window sub-switch (rear
LH or RH)

Rear LH or RH 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, the power window lock signal is transmitted to any power window sub-switches by
power window serial link. This prevents the 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.
When power and ground are supplied, the BCM continues 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-II. Refer to GW-30, "
CONSULT-II Function (BCM)" .

ANTI-PINCH SYSTEM
Power window main switch and each power window sub-switch recognizes and controls the door glass condi-
tion by reading encoder signals 1 and 2.
If a door glass is subject to a certain resistance due to a foreign material obstruction during the following close
operation.

automatic close operation when ignition switch is in the “ON” position

automatic close operation during retained power operation

Key cylinder switch close operation during retained power operation
The power window switch reads encoder signal 1, It stops UP operation of the motor, and sends a signal for
down operation to lower the window by a certain amount (150mm, 5.91 in)
INITIALIZATION
Perform the initialization when the following operations are performed or when the auto up operation is not
performed. Refer to GW-63
(Front door), GW-68 (Rear door).

When the power supply to the power window main switch, power window sub-switch or each power win-
dow motor is cut off by the removal of battery terminal or the battery fuse is blown.

Disconnection and connection of power window main switch or each power window sub-switch harness
connector.

Removal and installation of regulator assembly.

Removal and installation of motor from regulator assembly.

Operation of regulator assembly as an independent unit.

Removal and installation of glass.

Removal and installation of door glass run.
CAUTION:
The following operations are not performed under the condition that the initialization is not per-
formed yet.

Auto up operation

Anti-pinch function

FAIL-SAFE CONTROL
The encoder signal detects the up / down speed / detection of door glass. If the malfunction is detected to the
encoder signal or the difference between the glass fully closed position (memorized in power window main
switch or power window sub-switch) and the actual glass position is detected, it shifts into the fail-safe control
It is shifts into the fail-safe control, the initialization is not performed and the following function is not activated

Auto up operation

Anti-pinch function
It is shifts into the fail-safe control, performed the initialization to resume normal operation condition.
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 cylin-
der is placed on NEUTRAL.

When the ignition switch is turned ON while the power window DOWN is operated.
CAN Communication System DescriptionNIS0021H
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.
CAN Communication UnitNIS0021I
Refer to LAN-50, "CAN System Specification Chart"
DTC Condition
Pulse sensor detects malfunctionDuring the glass opening/closing operation, a pulse signal is continuously
detected for the specified terms or more
Both pulse sensors detect malfunctionDuring the glass opening/closing operation, both pulse signals are not
detected for the specified values or more
Pulse direction malfunctionThe following condition is detected for the specified values or more. The
pulse signal (detected during glass open/close operation) detects the
opposite direction to the driving direction of power window motor.
Glass recognized position malfunction 1During the glass opening/closing operation, the difference between the
glass fully closed position (memorized in power window main switch or
power window sub-switch) and the actual glass position is detected for
the specified values or more.
Glass recognized position malfunction 2During the glass opening/closing operation, a pulse count is detected that
is above the glass full stroke
Glass fully closed position not updated malfunctionContinuously perform the glass open/close operation (with the glass not
fully closed) at the specified value (approx. 10 time) or more
