No. Component Function
1. Combination meter Combination meter transmits the vehicle speed sig-
nal to BCM via CAN communication.
BCM also receives the vehicle speed signal from
ABS actuator and electric uni
t (control unit) via CAN
communication. BCM compares both signals to de-
tect the vehicle speed.
Security indicator lamp is located on combination
meter.
Security indicator lamp blinks when ignition switch
is in any position other than ON to warn that NIS-
SAN VEHICLE IMMOBILIZER SYSTEM-NATS
[NVIS (NATS)] is on board.
Refer to MWI-59, "
METER SYSTEM : Combination
Meter".
2. Push-button ignition switch Push-button ignition switch has push switch inside
which detects that push-button ignition switch is
pressed, and then transmits ON/OFF signal to
BCM. BCM changes the ignition switch position with
the operation of push-button ignition switch. BCM
maintains the ignition switch position status while
push-button ignition switch is not operated.
3. BCM BCM controls INTELLIGENT KEY SYSTEM (EN-
GINE START FUNCTION), NISSAN VEHICLE IM-
MOBILIZER 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 ver-
ification 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 en-
gine.
Refer to BCS-6, "
BODY CONTROL SYSTEM :
Component Parts Location" for detailed installation
location.
4. 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/un-
lock operation signal to BCM.
Refer to PWC-7, "
Main Power Window And Door
Lock/Unlock Switch".
5. Front door lock assembly LH Door key cylinder switch is integrated into front door
lock assembly (driver side).
Door key cylinder switch detects door LOCK/UN-
LOCK operation using mechanical key, and then
transmits the operation signal to BCM.
Refer to DLK-17, "
INTELLIGENT KEY SYSTEM :
Front Door Lock Asse
mbly (Driver Side)".
6. Rear door lock actuator LH Rear door lock actuator locks/unlocks the rear door
latch assembly.

Inspect according to Diagnosis Procedure of the system.
Is malfunctioning part detected?
YES >> GO TO 8.
NO >> Check according to GI-42, "
Intermittent Incident".
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is detected, erase it.
>> GO TO 9.
9.FINAL CHECK
When DTC is detected in step 2, perform DTC CONFIRMATION PROCEDURE again, and then check that the
malfunction is repaired securely.
When symptom is described by the customer, refer to confirmed symptom in step 3 or 4, and check that the
symptom is not detected.
Is DTC detected and does symptom remain?
YES-1 >> DTC is detected: GO TO 7.
YES-2 >> Symptom remains: GO TO 4.
NO >> Before returning the vehicle to the customer, always erase DTC.

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 CVT and A/T models).
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: J-39565 and mechanic's 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 fasteners 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 be eliminated only
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 DLK-135, "
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 loos ening and retightening the component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-50397) is available through your authorized NISSAN Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
• Always check with the Parts Department for the latest parts information.
• The materials contained in the NISSAN Squeak and Rattle Kit (J-50397) are listed on the inside cover of the
kit; and can each be ordered separately as needed.
• The following materials not found in the kit can also be used to repair squeaks and rattles.
- SILICONE GREASE: Use instead of UHMW tape that will be visible or does not fit. The silicone grease will
only last a few months.
- SILICONE SPRAY: Use when grease cannot be applied.
- DUCT TAPE: Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.

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.
