ILLUMINATION CONTROL SYSTEM

System Description
INFOID:0000000005550766
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 commu-
nication, 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.
