POWER WINDOW SERIAL LINK
With Front Power Window Anti-pinch System
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.
With Front and Rear Power Window Anti-pinch System
Power window main switch, front power window switch (passenger side), rear power window 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 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.
The under mentioned signal is transmitted from power window main switch to rear power window switch (LH
or RH)

Rear LH or RH side door window operation signal.

Power window lock signal.

Retained power operation signal.
POWER WINDOW LOCK
With Front Power Window Anti-pinch System
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 the power window motors from operating.
With Front and Rear Power Window Anti-pinch System
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 front power window switch (passenger
side) and rear power window 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 / with front power window anti-pinch system

through BCM terminal 53

to power window main switch terminal 10

to rear power window switch (LH and RH) terminals 1.
Power is supplied for 45 seconds / with front and rear power window anti-pinch system

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-40, "
CONSULT-II Inspection Procedure" .
ANTI-PINCH SYSTEM
With front power window 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 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 front power window switch (passenger side) controls each power window motor
for open and the power window will be lowered about 150 mm (5.91 in).
With front and rear power window anti-pinch system
Power window main switch and each power window switch monitors the power window motor operation and
the power window position (full closed or other) for each power window by the signals from encoder and limit
switch in power window motor.
When power window 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 each power window 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, 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 DescriptionAIS004PY
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 UnitAIS004RO
Refer to LAN-6, "CAN Communication Unit" .

CONSULT-II Inspection ProcedureAIS004QB
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “ON”.
2. Connect “CONSULT-II and CONSULT-II CONVERTER” to the
data link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “BCM”.
If “BCM” is not indicated, go to Refer to GI-40
, “CONSULT-II
Date Link Connector (DLC) Circuit”
6. Touch “RETAINED PWR”.

Test Item Description
RETAINED PWRThis test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in “OFF” position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-II might be stuck if
“RETAINED PWR” is turned to “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWRRap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps

MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).

Signals are transmitted,

through rear window defogger relay terminals 5 and 7

to rear window defogger terminal 1

Rear window defogger terminal 2 is grounded through body grounds B15 and B45.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON,
Power is supplied

through rear window defogger relay terminal 7

through fuse block (J/B) terminal 2C
