System DescriptionNKS004WN
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) through the CAN communication lines. The CPU (central
processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays,
when energized, direct power to the respective headlamps, which then illuminate.

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal from combination switch reading func-
tion (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ) the headlamp to illuminate. This
input signal is communicated to the IPDM E/R through the CAN communication lines. The CPU located in the
IPDM E/R controls the headlamp low relay coil, which when energized, supplies power,

With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting headlamp high beams to illuminate. High beam request signal and low beam request signal is com-
municated to the IPDM E/R through CAN communication. The CPU located in the IPDM E/R controls head-
lamp high relay and headlamp low relay turned ON, which when energized, supplies power,

System DescriptionNKS004XD

BCM (Body Control Module) controls headlamps low beam, high beam and daytime light operation.

Daytime light system operates parking, license plate, side marker, tail lamps and headlamp low beam
according to signals from unified meter and A/C amp. (receive parking brake switch signal through CAN
communication), ECM (receive engine status signal through CAN communication), lighting switch, and
ignition switch.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, side
marker, tail lamps, headlamp bulbs and high beam solenoids according to CAN communication signals
from BCM.

Unified meter and A/C amp. operates high beam indicator lamp according to CAN communication signals
from BCM.

With the power and ground supplied, headlamp bulbs illuminate. High beam solenoids move the bulb shades
in the front combination lamps, and the bulb shades change to high beam position.
Unified meter and A/C amp. receives signal from BCM through CAN communication, and then combination
meter indicator illuminates high beam,
DAYTIME LIGHT OPERATION
Once the parking brake is turned OFF after ignition switch ON, if the lighting switch is turned OFF while engine
is running, the BCM outputs the signal requesting parking, license plate, side marker, tail lamps and headlamp
low beam to illuminate. This output signal is communicated to the IPDM E/R through CAN communication.
