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 30 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 lamps OFF, the lamps will illuminate again when
• a signal is received from a 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
The interior lamp battery saver control time period can be changed with the function setting of CONSULT-III.

ILLUMINATION CONTROL SYSTEM

System Diagram

INFOID:0000000005550741

System Description

INFOID:0000000005550742

The illumination lamps operation is dependent upon the position 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 (or if the auto light system is activated) the BCM (body control module) receives input requesting the park-
ing lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module
engine room) via 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 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 30 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 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
lamps have been turned off by the battery saver control, the illumination lamps illuminate again.

Part name

Description

BCM

The BCM monitors the lighting switch position with the combina-
tion switch reading function.  The BCM requests, via CAN com-
munication, that the IPDM E/R activate the tail lamp relay. 

IPDM E/R

The IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication network. 

Combination meter (illumination control switch)

The illumination control switch is a part of the combination meter.  
The combination meter controls illumination intensity by varying 
ground to the illumination lamps based on the illumination control 
switch position. 

Combination switch (lighting and turn signal switch)

The combination switch (lighting and turn signal switch) provides 
input to the BCM about the lighting switch position.
