HEADLAMP (HALOGEN TYPE)

System Diagram

INFOID:0000000001712345

System Description

INFOID:0000000001712346

Control of the headlamp system operation 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
requesting the headlamps and park lamps to illuminate. This input is communicated to the IPDM E/R (intelli-
gent power distribution module 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.

HEADLAMP (HALOGEN TYPE)

When the lighting switch is in 2ND position, the BCM receives input requesting the headlamps to illuminate.
This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of the IPDM E/R
controls the headlamp low relay coil which supplies power to the low beam headlamps. 

HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION

With the lighting switch in the 2ND position and placed in HIGH position, the BCM receives input requesting
the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a sig-
nal to the BCM. This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of
the combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R
controls the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) via the CAN communication lines and turns
the high beam indicator lamp ON.

DAYTIME RUNNING LIGHT SYSTEM

System Diagram

INFOID:0000000001712349

System Description

INFOID:0000000001712350

The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the high
beam headlamps at approximately half illumination whenever the engine is operating. If the parking brake is
applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate
once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking
brake is applied.

DAYTIME RUNNING LIGHT SYSTEM

Component Parts Location

INFOID:0000000001712351

Component Description

INFOID:0000000001712352

After starting the engine with the parking brake released and the lighting switch in the OFF or 1ST position, the
headlamp high beam automatically turns on at a reduced intensity. With the lighting switch in the 2nd position
or with autolamps ON, the headlamps function the same as conventional light systems.

OPERATION

The BCM monitors inputs from the parking brake switch and the combination switch to determine when to acti-
vate the daytime light system.  The BCM sends a daytime light request to the IPDM E/R via the CAN commu-
nication lines.  The IPDM E/R grounds the daytime light relay which in turn, provides power to the ground side
of the LH high beam lamp.  Power flows backward through the LH high beam lamp to the IPDM E/R, through
the high beam fuses, through the RH high beam lamp circuit to the RH high beam lamp and on to ground.  The
high beam lamps are wired in series which causes them to illuminate at a reduced intensity.
