HEADLAMP AIMING SYSTEM (MANUAL)
System DiagramINFOID:0000000001527662
System DescriptionINFOID:0000000001527663
The headlamp aiming system (manual) controls the headlamp light axis height according to input from the
headlamp aimer switch. The variable internal resistance of the headlamp aimer switch controls the signal
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.

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.
