HEADLAMP (XENON)
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.

BCM• Monitors the combination switch position.
Requests the IPDM E/R (via CAN communication lines) to actuate the headlamp
high and low relays based on combination switch position .
Requests the combination meter (via CAN communication lines) to turn the high
beam indicator lamp ON.
IPDM E/RControls the integrated headlamp high and low relays based on input from the BCM
over the CAN communication lines.
Combination switch
(Lighting & turn signal switch)Refer to BCS-9, "
System Description".
Combination meter
(High beam indicator lamp)Controls the high beam indicator lamp ON during high beam operation based on input
from the BCM over the CAN communication lines.
Headlamp assem-
blyHID control unit Controls electricity flow through the xenon bulb.
Xenon bulbUses two tungsten electrodes and is filled with xenon gas and other metal halides.
Electricity flows between the electrodes to illuminate.
High beam solenoid Actuates the mobile valve shade to control high and low beam operation.
Mobile valve shadeWhen actuated by the high beam solenoid, it shades light output from the xenon bulb
for low beam operation and opens to allow more light output during high beam opera-
tion.

DAYTIME LIGHT SYSTEM
System DiagramINFOID:0000000001527654
System DescriptionINFOID:0000000001527655
The daytime light system operates the front clearance lamps, rear tail lamps and license plate lamps. The
BCM monitors the engine running status and lighting switch (combination switch) signal to determine whether
the daytime light system should be activated. With the engine running and the lighting switch OFF, the BCM
sends a signal via CAN communication to the IPDM E/R (Intelligent Power Distribution Module Engine Room)
to activate the headlamp low relay and the daytime light relay. The IPDM E/R supplies ground to the headlamp
low relay coil and daytime light relay coil which then energize to send power to the low beam headlamps, front
clearance lamps, rear tail lamps and license plate lamps.

HEADLAMP (HALOGEN)
HEADLAMP (HALOGEN) : DescriptionINFOID:0000000001523259
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on
inputs from the BCM via the CAN communication lines. When the headlamp high relay is energized, power
flows through fuses 34 and 35, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp high beam.
