VOLTAGE CHECK METHOD
To help in understanding the diagnosis of open circuits please refer to the previous schematic.
In any powered circuit, an open can be found by methodically checking the system for the presence of voltage.
This is done by switching the DMM to the voltage function.
Connect one probe of the DMM to a known good ground.
Begin probing at one end of the circuit and work your way to the other end.
With SW1 open, probe at SW1 to check for voltage.
voltage; open is further down the circuit than SW1.
no voltage; open is between fuse block and SW1 (point A).
Close SW1 and probe at relay.
voltage; open is further down the circuit than the relay.
no voltage; open is between SW1 and relay (point B).
Close the relay and probe at the solenoid.
voltage; open is further down the circuit than the solenoid.
no voltage; open is between relay and solenoid (point C).
Any powered circuit can be diagnosed using the approach in the previous example.
Testing for “Shorts” in the Circuit
To simplify the discussion of shorts in the system, please refer to the following schematic.
RESISTANCE CHECK METHOD
Disconnect the battery negative cable and remove the blown fuse.
Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the
fuse.
Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known
good ground.
With SW1 open, check for continuity.
continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.
Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good
ground. Then, check for continuity.
continuity; short is between SW1 and the relay (point B).
no continuity; short is further down the circuit than the relay.
Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and
a known good ground. Then, check for continuity.
continuity; short is between relay and solenoid (point C).
no continuity; check solenoid, retrace steps.
VOLTAGE CHECK METHOD
Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid discon-
nected) powered through the fuse.
Turn the ignition key to the ON or START position. Verify battery voltage at the battery + side of the fuse
terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground).
With SW1 open and the DMM leads across both fuse terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).

Tow Truck TowingNAS00081
CAUTION:
All applicable state or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.
It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.
Always attach safety chains before towing.
When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.
Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:
Never tow automatic transmission models with the rear wheels on the ground or four wheels on
the ground (forward or backward), as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under
the rear wheels.
When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.Never secure the steering wheel by turning the ignition key to the
LOCK position. This may damage the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.
When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle
should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.
If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.

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)" .

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).

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"
