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 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 to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation 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.

SYSTEM DIAGRAM (WITHOUT INTELLIGENT KEY SYSTEM)
OUTLINE
• Interior room lamp* is controlled by the interior room lamp timer control function of the BCM.
• Cargo lamp is controlled by the cargo lamp control function of the BCM.
• Push-button ignition switch illumination is controlled by the push-button ignition switch illumination control
function of BCM and combination meter.
The timer control functions of the BCM activate based on inputs from the key cylinder lock/unlock switch LH,
the door switches, the key switch and door lock/unlock switches.
*Interior room lamp and map lamp (when lamp switch is in DOOR position).
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM
begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
• When the front door LH is unlocked with key fob, main power window and door lock/unlock switch, power
window and door lock/unlock switch RH or front door lock assembly LH (key cylinder switch).
• When a door opens → closes and the push-button ignition switch is not pressed (with Intelligent Key sys-
tem).
• When a door opens → closes and the key is not inserted in the ignition switch (without Intelligent Key sys-
tem).
Timer control is cancelled under the following conditions.
• When the front door LH is locked with key fob, main power window and door lock/unlock switch, power win-
dow and door lock/unlock switch RH or front door lock assembly LH (key cylinder switch).
• A door is opened (door switch turns ON).
• Ignition switch is turned ON.
Interior lamp operational settings can be changed with the function setting of CONSULT.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the batte ry 10 minutes after the ignition switch is turned OFF.

The BCM controls power and ground to all interior lamps.
After the battery saver system turns the la mps OFF, the lamps will illuminate again when
• a signal is received from a key fob, main power window and door lock/unlock switch, power window and
door lock/unlock switch RH or when the front door lock assembly LH (key cylinder switch) is locked or
unlocked
• a door is opened or closed
• the key is removed from or inserted into t he ignition switch (without Intelligent Key system).
The interior lamp battery saver control time per iod can be changed with the function setting of CONSULT.
ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM : System DescriptionINFOID:0000000012432723
SYSTEM DIAGRAM
OUTLINE
The illumination lamps operation is dependent upon the posit ion of the combination switch (lighting and turn
signal switch). When the combination switch (lighting and turn signal switch) is placed in the 1ST or 2ND posi-
tion the BCM (body control module) receives input requesting the parking lamps to illuminate. This input is
communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communica-
tion lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized,
this relay directs power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the 1st or 2nd position and the ignition
switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition,
the illumination lamps remain illuminated for 10 minutes unless the combination switch (lighting and turn signal
switch) position is changed. If the combination switch (lighting and turn signal switch) position is changed, then
the illumination lamps are turned off after a 15 second delay. When the combination switch (lighting and turn
signal switch) is turned from OFF to 1st or 2nd position after illumination lamps have been turned off by the
battery saver control, the illumination lamps illuminate again.
