System Description
INFOID:0000000006607843
The headlamp system for Canada vehicles is equipped with a daytime light relay 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 Description
INFOID:0000000006607844
After starting the engine with the parking brake released and the combination switch (lighting and turn signal
switch) in the OFF or 1ST position, the headlamp high beam automatically turns on at a reduced intensity.
With the combination switch (lighting and turn signal 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 (lighting and turn signal
switch) to determine when to activate the daytime light system. The BCM sends a daytime light request to the
IPDM E/R via the CAN communication lines. The IPDM E/R grounds the daytime light relay which in turn, pro-
vides 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.

System Description
INFOID:0000000006178996
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The combina-
tion switch (lighting and turn signal switch) signal to the BCM is monitored with the BCM combination switch
reading function. When the fog lamps are turned ON with the combination switch (lighting and turn signal
switch), the BCM sends a front fog lamp request signal via CAN communication lines to the IPDM E/R. The
IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.

FRONT FOG LAMP OPERATION
When the combination switch (lighting and turn signal switch) is in front fog lamp ON position and also in 1ST
or 2ND position or AUTO position (headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP1, 2
ON or the AUTO LIGHT ON. The BCM sends a front fog lamp request ON signal via the CAN communication
lines to the IPDM E/R. The IPDM E/R then turns ON the front fog lamp relay sending power to the front fog
lamps.

TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal switch) is in LH or RH position with the ignition switch in
ON position, the BCM detects the TURN RH or TURN LH ON request. The BCM outputs the flasher signal to
the respective turn signal lamp. The BCM also sends a turn indicator signal ON request via the CAN commu-
nication lines to the combination meter. The combination meter then activates the appropriate turn signal indi-
cator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazard indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combination meter then activates the hazard indicator and audible
buzzer.
REMOTE KEYLESS ENTRY OPERATION
The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard
lamps.
