System DescriptionINFOID:0000000001523246
The BCM (Body Control Module) controls parking, license plate and tail lamps operation based on lighting
switch (combination switch) input. The BCM requests the IPDM E/R (Intelligent Power Distribution Module
Engine Room) (via CAN communication lines) to activate the tail lamp relay (without daytime light system) or
the daytime light relay (with daytime light system).

Part Description
BCM Monitors the combination switch position.
Requests the IPDM E/R (via CAN communication lines) to actuate the tail lamp relay
(without daytime light system) or the daytime light relay (with daytime light system.)
IPDM E/RControls the integrated tail lamp relay (without daytime light system) or the daytime
light relay (with daytime light system) based on input from the BCM over the CAN com-
munication lines.
