INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and the instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar finisher
4. Instrument panel to windshield
5. Instrument panel pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noi se. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or ra ttle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shift selector assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation pr ocedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them wh ile driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the ar eas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-50397) 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, se curing 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 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.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the cons ole panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the c onsole at the clip locations until the clips engage.

REMOVAL
WARNING:
• Before servicing the SRS, turn ig nition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Before disconnecting the air bag diagnosis sensor unit harness conn ectors, be sure to disconnect
each harness connector of the front shoulder belt pre-tensioners to prevent accidental air bag
deployment by static electricity and seat belt pre-tensioner operation.
• Do not use the air tools or electric tools for servicing.
• When replacing the air bag diagno sis sensor unit, always check with th e parts department for the lat-
est parts information. Installing an incorrect air bag diagnosis sen sor unit may or may not cause the
air bag warning lamp to illuminate and may cause in correct deployment of the supplemental air bags
and seat belt pre-tensioners in a collision r esulting in serious personal injury or death.
1. Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) or part
number using CONSULT.
2. Disconnect both the negative and positive battery terminal s, then wait at least three minutes. Refer to PG-
73, "Removal and Installation (Battery)".
3. Disconnect the harness connector fo r the following SRS components: SB-8, "Removal and Installation"
(Front shoulder belt pre-tensioner LH/RH).
4. Remove the center console. Refer to IP-18, "Removal and Installation"
.
5. Disconnect the harness connector from air bag diagnosis sensor unit.
6. Remove the air bag diagnosis sensor unit bolts , then remove the air bag diagnosis sensor unit.
