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 models, drive position on A/T models).
6) Raisethevehicleonahoistandhitatirewitharubberhammer.
lDrive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
lIf 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
(Engine Ear or mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
lremoving 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.
ltapping 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.
lfeeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
lplacing a piece of paper between components that you suspect are causing the noise.
llooking for loose components and contact marks.
Refer toBL-8, "
Generic Squeak and Rattle Troubleshooting".
REPAIR THE CAUSE
lIf the cause is a loose component, tighten the component securely.
lIf 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 are available through your authorized Nissan Parts Department.
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.
Each item can be ordered separately as needed.

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
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. 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 these 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 mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting 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.

HOOD
3. Remove the hood lock assembly.
4. Disconnect the hood lock cable from the hood lock, and clip it from the radiator core support upper and
hood ledge.
5. Remove the hood lock opener mounting bolts, and remove the
hood lock opener.
6. Separate the grommet from the lower dash panel. Pull the hood
lock cable out through the passenger compartment.
CAUTION:
While pulling, be careful not to damage (peeling) the out-
side of the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine
room.
CAUTION:
Be careful not to bend the cable too much, keeping the
radius 100 mm (3.94 in) or more.
2. Make sure the cable is not offset from the positioning grommet,
and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install the cable securely to the lock in order of (1) and (2).
5. After installing, check the hood lock adjustment and hood
opener operation.
6. After installing, perform hood fitting adjustment. Refer toBL-12,

THEFT WARNING SYSTEM
System Description
EIS00DBX
DESCRIPTION
Operation Flow
Setting the theft warning system
Initial condition
lIgnition switch is in OFF position.
Disarmed phase
lWhen the vehicle is being driven or when doors are open, the theft warning system is set in the disarmed
phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase
lThe theft warning system turns into the “pre-armed” phase when all doors are closed and locked. The
security indicator lamp illuminates for 20 seconds. Then, the system automatically shifts into the “armed”
phase.
Canceling the set theft warning system
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the keyfob.
2. Unlock the doors with the ignition key.
Activating the alarm operation of the theft warning system
Make sure the system is in the armed phase.
When any of the following operation 1, 2 or 3 is performed, the system sounds the siren control unit or horn
and flashes the turn signal lamps for about 30 seconds.
1. Engine hood or any doors is opened before unlocking door with keyfob.

lto BCM terminal 4.
Ground is supplied
lto BCM terminal 55
lthrough body grounds M21, M80 and M83
lto IPDM E/R terminals 38 and 59
lthrough body ground E21, E41 and E61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the theft warning system is controlled by the engine hood and doors.
To activate the theft warning system, BCM must receive signals indicating the doors are closed and locked.
When a door is open, BCM terminal 12, 14, 15 or 16 receives a ground signal from each door switch.
When the engine hood is open, IPDM E/R terminal 41 receives a ground signal
THEFT WARNING SYSTEM ALARM OPERATION
The vehicle security system is triggered by
lopening a door
lopening the hood
ldetecting battery disconnect/connection.
The vehicle security system will be triggered once the system is in armed phase,
when BCM receives a ground signal at terminals 12, 14, 15, 16 (door switch) or IPDM E/R receives a ground
signal at terminal 41 (hood switch).
When the vehicle security system is triggered, siren control unit or horn is activate.
The alarm automatically turns off after 30 seconds, but will reactivate if the vehicle is tampered with again.
THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door must be unlocked with keyfob.
When the BCM receives either one of these signals or unlock signal from keyfob the theft warning system is
deactivated. (Disarmed phase)
