Component Parts and Har ness Connector LocationINFOID:0000000001328265
System DescriptionINFOID:0000000001328266
Control of the headlamp system operation is dependent upon t he 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) located in the IPDM E/R contro ls the headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.

Power is supplied at all times
 to headlamp high relay, located in IPDM E/R

DAYTIME LIGHT SYSTEM
DAYTIME LIGHT SYSTEM
Component Parts and Harness Connector LocationINFOID:0000000001328291
System DescriptionINFOID:0000000001328292
Daytime light system turns ON daytime light lamps while driving. Daytime light lamps are not turned ON if
engine is activated with parking brake ON. Release parki ng brake to turn ON daytime light lamps. The lamps
turn OFF when the lighting switch is in the 2ND pos ition or AUTO position (headlamp is ON) and when the
lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake
itself).
The parking brake signal and engine run or stop signal ar e sent to BCM (body control module) by CAN com-
munication line, and control daytime light system.

System DescriptionINFOID:0000000001328328
Control of the front fog lamps is dependent upon the position of the combination switch (lighting switch). The
lighting switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp opera-
tion.When the lighting switch is placed in the front fog lamp on position the BCM (body control module)
receives input signal requesting the front fog lamps to illuminate. When the headlamps are illuminated, this
input signal is communicated to the IPDM E/R (inte lligent power distribution module engine room) through the
CAN communication lines. The CPU (central processing unit) located in the IPDM E/R controls the front fog
lamp relay coil. When activated, this relay directs power to the front fog lamps.

Component Parts and Harness Connector LocationINFOID:0000000001328382
System DescriptionINFOID:0000000001328383
Control of the parking, license plate, side marker and tail lamp operation is dependent upon the position of the
lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body
control module) receives input signal requesting the parki ng, license plate, side marker and tail lamps to illumi-
nate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication lines. CPU (central processi ng unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs pow er to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp cont rol unit is controlled, and a tail lamp (LED) is made to
turn ON.
