INTERIOR ROOM LAMP CONTROL SYSTEM
a signal is received from an Intelligent Key or main power window and door lock/unlock switch, 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-III.

ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM
System DiagramINFOID:0000000001730918
System DescriptionINFOID:0000000001730919
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 parking 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 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 30 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.

Part name Description
BCMThe 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/RThe IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication network.
Combination switchThe combination switch provides input to the BCM about the light-
ing switch position.
