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 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 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.
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 pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplic ated 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 on the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator 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 c an usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

INTERIOR ROOM LAMP
Component Parts and Har ness Connector Location INFOID:0000000004306628
System Description INFOID:0000000004306629
When room lamp switch is in DOOR position, room la mp ON/OFF is controlled by timer according to signals
from switches including key switch, front door switch LH, unlock signal from keyfob, door lock and unlock
switch, key cylinder lock and unlock switch, ignition switch.
When room lamp turns ON, there is a gradual brightening over 1 second.
When room lamp turns OFF, there is a gradual dimming over 1 second.
Interior room lamp timer is controlled by BCM (body control module).
Interior room lamp timer control settings can be changed with CONSULT-III.
POWER SUPPLY AND GROUND Power is supplied at all times (without Intelligent Key system)
• through 10A fuse [No. 14, located in fuse block (J/B)]
• to key switch and key lock solenoid terminal 2,
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57,
• through 40A fusible link (letter g , located in fuse and fusible link box)
• to BCM terminal 70.
Power is supplied at all times (with Intelligent Key system) 1. BCM M18, M19 and M20 (view with
glove box removed) 2. Key switch and key lock solenoid
(without Intelligent Key) M27 3. Key switch and ignition knob switch
(with Intelligent Key) M73

When interior room lamp switch is ON, ground is supplied
• to interior room lamp terminal 1
• through map lamp (with map lamp) terminal 7
• through map lamp (with map lamp) terminal 1
• through grounds M57 and M61.
Power is supplied

INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System When room lamp switch is in DOOR position, and w hen all conditions below are met, BCM performs timer
control (maximum 30 seconds) for room lamp ON/OFF.
In addition, when the interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 sec-
ond.
Power is supplied
• through 10A fuse [No. 14, located in fuse block (J/B)]
• to key switch and key lock solenoid terminal 2.
When the key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM termi-
nal 37.
When front door key cylinder switch LH is unlocked, ground is supplied
• to BCM terminal 7
• through front door key cylinder switch LH terminal 3
• through front door key cylinder switch LH terminal 2
• through grounds M57 and M61.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp timer operation condition is met, and turns the room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON),
Power is supplied
• through key switch and key lock solenoid terminal 1
• to BCM terminal 37.
When key is removed from key switch and key lock soleno id (key switch OFF), the power supply to BCM ter-
minal 37 is terminated. BCM detects that key has been re moved, determines that interior room lamp timer
conditions are met, and turns the room lamp ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), voltage at BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM
determines that conditions for room lamp operation are met and turns the room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:
• Front door LH is locked (locked by front door key cylinder switch LH, keyfob or door lock/unlock switch).
• Front door LH is opened (front door switch LH).
• Ignition switch ON.
With Intelligent Key System When the room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 second) for room lamp ON/OFF.
In addition, when interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
• through 10A fuse (No. 31, located in fuse and fusible link box)
• to key switch and ignition knob switch terminals 2 and 4.
When key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal
37.
When the ignition knob switch is released, power wil l not be supplied to Intelligent Key unit terminal 27.
When front door key cylinder switch LH is unlocked, ground is supplied
• to BCM terminal 7
• through front door key cylinder switch LH terminal 3
