DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle "twist".
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.

Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.

If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:

removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.

tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will only be eliminated
temporarily.

feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.

placing a piece of paper between components that you suspect are causing the noise.

looking for loose components and contact marks.
Refer to BL-10, "
Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE

If the cause is a loose component, tighten the component securely.

If the cause is insufficient clearance between components:
–separate components by repositioning or loosening and retightening the component, if possible.
–insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts
Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

INTELLIGENT KEY SYSTEM
Revision: 2004 November 2004 FX35/FX45
System DescriptionAIS004MW

The Intelligent Key system is a system which can lock and unlock the doors (door lock function) and start
the engine (engine start function) by carrying around the Intelligent Key, which operates based on the
results of electrical key-ID verification using two-way communications between the Intelligent Key and the
vehicle

Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote control entry functions)

As an ignition key warning function, when a door is locked or unlocked with entry switch or remote control-
ler button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

Even if the vehicle or Intelligent Key battery runs down, the door can be locked and unlocked and the
engine started with the mechanical key built into the Intelligent Key.

If an Intelligent Key was lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can
be registered.

It has been made possible to diagnose the system, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK FUNCTION
Operation Description

When the driver door, passenger door, or back door request switch is pressed, Intelligent Key unit sends a
request signal from the transmission antenna corresponding to the pressed door request switch, key-ID
verification is performed using two-way communication with Intelligent Key, and if ID is successfully veri-
fied, a door lock/unlock request signal is sent to BCM (Body Control Module) using CAN communication
to lock/unlock the door lock.

When door is locking, door is unlocked, when door is unlocking, door is locked.

When door is locked/unlocked by door request switch operation, hazard lamps flash and Intelligent Key
warning buzzer sounds.

With the locking operation of door request switch, door lock actuators of all door are locked.
