Revision: October 20052005 QX56
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.
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 bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The 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. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner 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.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
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 rearseat back 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.

HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:

Main Harness, Console Sub-harness, Console Switch Sub-har-
ness and Optical Sensor Sub-harness

Engine Room Harness LH View (Engine Compartment)

Engine Room Harness RH View (Engine Compartment) and
Generator Sub-harness

Engine Control Harness and Engine Control Sub-harness

Chassis Harness and Rear Sonar Sensor Sub-harness

Body Harness

Body No. 2 Harness
To use the grid reference
1. Find the desired connector number on the connector list.
2. Find the grid reference.
3. On the drawing, find the crossing of the grid reference letter column and number row.
4. Find the connector number in the crossing zone.
5. Follow the line (if used) to the connector.
CONNECTOR SYMBOL
Main symbols of connector (in Harness Layout) are indicated below.

Fuse EKS00BNG

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link EKS00BNH
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.

Never wrap outside of fusible link with vinyl tape.

Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00BNI
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:

Power seat

Power windows

Power door locks

Remote keyless entry system

Power sunroof

Rear window wiper
