COMPONENT PARTS
IPDM E/RThe IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication.
Push button ignition switch Provides ignition switch status to the BCM.
Door switches Provides door OPEN/CLOSED status to the BCM.
Combination switch
(lighting and turn signal switch) The combination switch (lighting and turn signal switch) provides
input to the BCM. The BCM then sends a tail lamp relay request
signal to the IPDM E/R via CAN communication to operate the il-
lumination system.
Trunk lamp switch and release solenoid
(trunk lamp switch) Provides trunk lamp switch OP
EN/CLOSED status to the BCM.
Power window and door lock/unlock switch RH Provides door lock/unlock position switch RH status to the BCM.
Main power window and door lock/unlock switch Provides door lock/unlock position switch LH status to the BCM.
Meter control switch
(illumination control switch) • Adjusts the illumination system and combination meter illumina-
tion brightness (with multiple illumination control).
• Only adjusts the combination meter illumination brightness
(with meter illumination control only).
Front door lock assembly LH (key cylinder switch) Provides front door lock assembly LH (key cylinder switch) door
lock/unlock switch position status to the BCM.

INTERIOR ROOM LAMP CONTROL SYSTEM
System DiagramINFOID:0000000009463863
System DescriptionINFOID:0000000009463864
OUTLINE
• Front room/map lamps and personal lamps rear are controll ed by the room lamp timer control function of the
BCM when lamp switch is in the DOOR position.
• Front step lamps are controlled by step lamp control function of BCM.
• Trunk room lamp is controlled by trunk lamp control function of BCM.
• Push-button ignition switch illumination is controlled by the push-button ignition switch illumination control
function of BCM.
• Interior room lamps are illuminated by the welcome light function of Intelligent Key system. Refer to DLK-32,
"WELCOME LIGHT FUNCTION : System Description".
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 Intelligent Key, main power window and door lock/unlock switch or
front door lock assembly LH (key cylinder switch)].
• When a door opens → closes.
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 or front door lock assembly LH (key cylinder switch)].
• A door is opened (door switch turns ON).
• Ignition switch is turned ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OF F even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the batte ry 15 minutes after the ignition switch is turned OFF.

INTERIOR ROOM LAMP CONTROL SYSTEM
The BCM controls the following interior lamps:
• Front step lamp LH/RH
• Front room/map lamp LH/RH
• Personal lamp rear LH/RH
• Vanity mirror lamp LH/RH (if equipped)
• Trunk room lamp
After the battery saver system turns the la mps OFF, the lamps will illuminate again when:
• A signal is received from an Intelligent Key or main power window and door lock/unlock switch or when the front door lock assembly LH (key cylinder switch) is locked or unlocked.
• A door is opened or closed.

System DescriptionINFOID:0000000009463866
WITH MULTIPLE ILLUMINATION CONTROL
The illumination system is activated by the combinat ion switch (lighting and turn signal switch) when the
switch is placed in the 1st or 2nd position (or if the auto light system is activated).
The illumination system and combination meter illuminati on brightness is adjustable using the meter control
switch (illumination control switch).
• The BCM (body control module) receives the parking lamp request signal from the combination switch (light-
ing and turn signal switch) to turn the lights on.
• The BCM sends the parking lamp request signal to t he IPDM E/R (intelligent power distribution module
engine room) via CAN communication.
• IPDM E/R receives the parking lamp request signal from the BCM to activate the tail lamp relay and provide
power to the illumination system.
WITH METER ILLUMINATION CONTROL ONLY
The illumination system is activated by the combinat ion switch (lighting and turn signal switch) when the
switch is placed in the 1st or 2nd position (or if the auto light system is activated).
Only the combination meter illumination brightness is adjustable using the meter control switch (illumination
control switch).

ILLUMINATION CONTROL SYSTEM
• The BCM (body control module) receives the parking lamp request signal from the combination switch (light-
ing and turn signal switch) to turn the lights on.
• The BCM sends the parking lamp request signal to t he IPDM E/R (intelligent power distribution module
engine room) via CAN communication.
• IPDM E/R receives the parking lamp request signal from the BCM to activate the tail lamp relay and provide power to the illumination system.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the 1st or 2nd position and the ignition
switch is set from ON or ACC to OFF, the battery save r control feature is activated. Under this condition, the
illumination system remains on for 15 minutes unless the combination switch (lighting and turn signal switch)
position is changed. If the combination switch (light ing and turn signal switch) position is changed, then the
illumination system is turned off after a 30 second delay . When the combination switch (lighting and turn signal
switch) is turned from OFF to 1st or 2nd position (or if auto light system is activated) after illumination system
has been turned off by the battery saver control, the illumination lights illuminate again.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
