INTERIOR ROOM LAMP CONTROL SYSTEM

Component Description

INFOID:0000000009465410

SWITCH OPERATION

When a door is opened, the door switch closes to send a ground signal to the BCM. When the trunk is opened,

the trunk lamp switch and trunk release solenoid closes sending a ground signal to the BCM. 

ROOM LAMP TIMER OPERATION

When the front room/map lamp assembly switch is in DOOR position and when all conditions below are met,

BCM begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.

• When the front door LH is unlocked [with Intelligent Key, main power window and door lock/unlock switch,

power window and door lock/unlock switch RH, or front door lock assembly (key cylinder switch)].

• When a door opens 

→ closes and the Intelligent Key is not inserted in the key slot.

Timer control is cancelled under the following conditions.

• When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch,

power window and door lock/unlock switch RH, or front door lock assembly (key cylinder switch)].

• A door is opened (door switch turns ON).

• Intelligent Key is inserted into the key slot.

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 battery 15 minutes after the ignition switch is turned OFF.

The BCM controls the interior lamps listed below

• Front step lamp LH and RH

• Rear step lamp LH and RH

• Front room/map lamp assembly

• Foot lamp LH and RH

• Personal lamp rear LH and RH

• Vanity mirror lamp LH and RH

• Trunk room lamp

After the battery saver system turns the lamps OFF, the lamps will illuminate again when

• a signal is received from an Intelligent Key, main power window and door lock/unlock switch or power win-

dow and door lock/unlock switch RH, or when the front door LH lock assembly (key cylinder switch) is locked

or unlocked

• a door is opened or closed

• the Intelligent Key is removed from or inserted into the key slot.

The interior lamp battery saver control time period can be changed with the function setting of CONSULT.

ILLUMINATION CONTROL SYSTEM

System Diagram

INFOID:0000000009465411

System Description

INFOID:0000000009465412

The illumination lamps operation is dependent upon the position of the lighting switch (combination switch).

When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) the BCM

(body control module) receives input requesting the illumination lamps to illuminate. This input is communi-

cated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication

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 illumination lamps, which then illuminate.

ILLUMINATION CONTROL SYSTEM

Component Description

INFOID:0000000009465414

ILLUMINATION OPERATION BY LIGHTING SWITCH

With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives

input requesting the illumination lamps to illuminate. This input is communicated to the IPDM E/R across the

CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil which, when energized,

directs power

BATTERY SAVER CONTROL

When the lighting switch (combination 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 15 minutes unless the lighting switch position is changed. If the lighting switch

position is changed, then the illumination lamps are turned off after a 30 second delay. When the lighting

switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps

have been turned off by the battery saver control, the illumination lamps illuminate again.
