System Description

INFOID:0000000005259707

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 LH high, headlamp RH high and headlamp low relay coils. When

energized, these relays direct power to the respective headlamps, which then illuminate.

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:0000000005259710

System Description

INFOID:0000000005259711

The headlamp system for Canada vehicles is equipped with a daytime light control that activates the high

beam headlamps at approximately half illumination whenever the engine is operating. If the parking brake is

depressed before the engine is started the daytime lights will not be illuminated. The daytime lights will illumi-

nate once the parking brake is released. Thereafter, the daytime lights will continue to operate when the park-

ing brake is depressed.

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.
