1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine rpm or
load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012430321
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for WorkINFOID:0000000012430322
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty
area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

1. Combination meter Combination meter transmits the vehicle
speed signal to BCM via CAN communica-
tion.
BCM also receives the vehicle speed signal
from ABS actuator and electric unit (control
unit) via CAN communication. BCM com-
pares both signals to detect the vehicle
speed.
Security indicator lamp is located on combi-
nation meter.
Security indicator lamp blinks when ignition
switch is in any position other than ON to
warn that NISSAN VEHICLE IMMOBILIZER
SYSTEM-NATS [NVIS (NATS)] is on board.
Refer to MWI-9, "
METER SYSTEM : Combi-
nation Meter".
2. Inside key antenna (instrument center) Inside key antenna (instrument center) de-
tects whether Intelligent Key is inside the ve-

3. ABS actuator and electric unit (control unit) ABS actuator and electric unit (control unit)
transmits the vehicle speed signal to BCM via
CAN communication.
BCM also receives the vehicle speed signal
from the combination meter via CAN commu-
nication. BCM compares both signals to de-
tect the vehicle speed.
Refer to
BRC-8, "
ABS Actuator and Electric
Unit (Control Unit)" for detailed installation lo-
cation.
4. Intelligent Key warning buzzer Intelligent Key warning buzzer warns the us-
er, who is outside the vehicle, of operation
confirmation according to Intelligent Key op-
eration and door request switch operation, or
of an inappropriate operation.
5. Transmission range switch Transmission range switch detects the CVT
shift selector lever position.
6. IPDM E/R Starter control relay is integrated in IPDM E/R
and used for the engine starting function.
Starter relay is controlled by BCM, and starter
control relay is controlled by IPDM E/R while
communicating with BCM. IPDM E/R sends
the starter control rela
y and starter relay sta-
tus signal to BCM.
7. BCM BCM controls INTELLIGENT KEY SYSTEM
(ENGINE START FUNCTION), NISSAN VE-
HICLE IMMOBILIZER SYSTEM-NATS [NVIS
(NATS)] and VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between
BCM and Intelligent Key when the Intelligent
Key is carried into the detection area of inside
key antenna, and push-button ignition switch
is pressed. If the ID verification result is OK,
ignition switch operation is available.
Then, when the ignition switch is turned ON,
BCM performs ID verification between BCM
and ECM. If the ID verification result is OK,
ECM can start engine.
Refer to
BCS-6, "
BODY CONTROL SYSTEM
: Component Parts Location" for detailed in-
stallation location.
8. Clutch interlock switch Clutch interlock switch detects that clutch
pedal is depressed, and then transmits ON/
OFF signal to the BCM.
9. Stop lamp switch Stop lamp switch detects that brake pedal is
depressed, and then transmits ON/OFF sig-
nal to the BCM.
10. Main power window and door lock/unlock switch Door lock and unlock switch is integrated into
the main power window and door lock/unlock
switch.
Door lock and unlock switch transmits door
lock/unlock operation signal to BCM.
Refer to
PWC-7, "
Main Power Window And
Door Lock/Unlock Switch".
11. CVT shift selector (park position switch) Park position switch is integrated into the
CVT shift selector and detects that the selec-
tor lever is in the P (park) position, then trans-
mits ON/OFF signal to the BCM and IPDM E/
