INTERIOR ROOM LAMP
Revision: 2004 November 2004 FX35/FX45

through key switch terminal 1

to BCM terminal 37.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated. BCM
detects that key has been removed, determines that interior room lamp and map lamp timer conditions are
met, and turns the interior room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and the key is not inserted in the key switch (key switch OFF), BCM termi-
nal 62 changes between 0V (door open) → 12V (door closed). The BCM determines that conditions for inte-
rior room lamp and map lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.

Driver door is locked [when locked keyfob or power window main switch (door lock and unlock switch),
door key cylinder switch].

Driver door is opened (driver door switch turns ON).

Ignition switch ON.
With Intelligent Key System
When interior room lamp and map lamp switch is in DOOR position, and when all conditions below are met,
BCM performs timer control (maximum 30 second) for interior room lamp and map lamp ON/OFF.
In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied

to 15A fuse [No. 22, located in fuse and fuse block (J/B)]

through key switch and ignition knob switch terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
And not turned ignition knob switch, power will not be supplied to Intelligent Key unit.
Ground is supplied

from BCM terminal 22

to power window main switch (door lock and unlock switch) terminal 14.
At the time that driver door are opened, BCM detects that driver door is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns the interior room lamp and map lamp
ON for 30 seconds.
Key is in ignition key cylinder (key switch ON), or turned ignition knob switch,
Power is supplied

through key switch and ignition knob switch terminal 4

to BCM terminal 37

through key switch and ignition knob switch terminal 2

to Intelligent Key unit terminal 27.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated. And
turned ignition knob switch, power supply to intelligent key unit is terminated. BCM detects that key has been
removed, determines that interior room lamp and map lamp timer conditions are met, and turns the interior
room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and the key is not inserted in the key switch (or not turned ignition knob
switch), BCM terminal 62 changes between 0V (door open) → 12V (door closed). The determines that condi-
tions for interior room lamp and map lamp operation are met and turns the interior room lamp ON for 30 sec-
onds.
Timer control is canceled under the following conditions.

Driver door is locked [when locked keyfob or power window main switch (door lock and unlock switch).
door key cylinder switch].

Driver door is opened (driver door switch terns ON).

Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left “ON”, it will not be turned out even when door is closed.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2004 November 2004 FX35/FX45
INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30 × 50 mm (1.18 × 1.97 in)
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: 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.
Generic Squeak and Rattle TroubleshootingAIS0059J
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting 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 noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon 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 rattle. 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. Shifter 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 procedures 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 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.
