HEADLAMP (HALOGEN)
System DiagramINFOID:0000000001523225
System DescriptionINFOID:0000000001523226
Control of the headlamp system operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 2nd position, the BCM (body control module) receives input
requesting the headlamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distri-
bution module engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM
E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to
the respective headlamps, which then illuminate.

System DiagramINFOID:0000000001527648
System DescriptionINFOID:0000000001527649
A mobile valve shade type xenon headlamp is used. The xenon headlamp uses one xenon bulb each on the
LH and RH side. The xenon headlamp switches between high beam and low beam by using a high beam
solenoid to move the mobile valve shade over the xenon bulb.
Control of the headlamp system is dependent upon the position of the lighting switch (combination switch).
When the lighting switch is placed in the 2nd position, the BCM (body control module) receives input request-
ing the headlamps to illuminate. This input is then communicated to the IPDM E/R (intelligent power distribu-
tion model engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM E/
R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to the
respective headlamps, which then illuminate.

AUTO LIGHT SYSTEM
System DiagramINFOID:0000000001523233
System DescriptionINFOID:0000000001523234
When the lighting switch is in AUTO position, it automatically turns ON/OFF the exterior lamps in accordance
with the ambient light levels.
The light and rain sensor detects ambient brightness and converts light (lux) to voltage which is output to the
BCM. The BCM (Body Control Module) controls auto light operation according to the signal inputs from the
light and rain sensor, lighting switch and ignition switch. If conditions are met, the BCM sends a request (via
CAN communication lines) to the IPDM E/R (Intelligent Power Distribution Module Engine Room) to activate
the exterior lamps.

Part Description
BCM Monitors lighting switch position, engine running status and parking brake status to
determine if conditions are set for daytime light system operation.
 Requests the IPDM E/R via CAN communication lines to ground the daytime light
relay coil.
IPDM E/RControls ground to the daytime light relay coil based on requests from the BCM (via
CAN communication lines).
Combination switch
(Lighting & turn signal switch)Refer to XX-XX, "*****"
.
Combination meterMonitors engine running status and forwards that information to the BCM via CAN
communication lines.
