HEADLAMP AIMING SYSTEM (AUTOMATIC)
System DiagramINFOID:0000000001527658
System DescriptionINFOID:0000000001527659
The headlamp aiming system (automatic) controls the headlamp light axis height appropriately according to
the vehicle height and vehicle speed as determined by the height sensor. The height sensor controls the sig-
nal ground of the headlamp aiming motors located on the front combination lamp LH and RH.

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.

DAYTIME LIGHT SYSTEM
Component Description
INFOID:0000000001527657
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, "*****"
.

FRONT FOG LAMP
System DiagramINFOID:0000000001523237
System DescriptionINFOID:0000000001523238
The BCM (Body Control Module) controls front fog lamp operation based on input from the lighting switch
(combination switch). The BCM requests (via CAN communication lines) the IPDM E/R (Intelligent Power Dis-
tribution Module Engine Room) to activate the integrated front fog lamp relay and requests the combination
meter to illuminate the front fog lamp light.

REAR FOG LAMP
System DiagramINFOID:0000000001527666
System DescriptionINFOID:0000000001527667
The BCM (Body Control Module) controls rear fog lamp operation based on input from the lighting switch
(combination switch). When the lighting switch is in the 1st or 2nd position or auto position and the rear fog
lamp switch is ON, the BCM outputs battery voltage to the rear fog lamps. The BCM sends a request signal to
the combination meter via CAN communication lines to illuminate the rear fog lamp indicator.
