Under this condition, the headlamps remain illuminated for 45 seconds unless the lighting switch position is
changed. If the lighting switch position is changed, then the headlamps are turned off.
This setting can be changed by CONSULT. Refer to BCS-20, "
HEADLAMP : CONSULT Function (BCM -
HEAD LAMP)" (with Intelligent Key system) or BCS-93, "HEADLAMP : CONSULT Function (BCM - HEAD
LAMP)" (without Intelligent Key system).
DAYTIME RUNNING LIGHT SYSTEM
DAYTIME RUNNING LIGHT SYSTEM : System DiagramINFOID:0000000012432771
DAYTIME RUNNING LIGHT SYST EM : System DescriptionINFOID:0000000012432772
The headlamp system is equipped with a daytime running light control that activates the high beam head-
lamps at approximately half illumination whenever the e ngine is operating. If the parking brake is applied
before the engine is started the daytime running lights will not be illuminated. The daytime running lights will
illuminate once the parking brake is released. Thereaf ter, the daytime running lights will continue to operate
when the parking brake is applied.
OPERATION
The BCM monitors inputs from the parking brake swit ch and the combination switch (lighting and turn signal
switch) to determine when to activate the daytime running light system. The BCM sends a daytime running
light request to the IPDM E/R via the CAN communication lines. The IPDM E/R grounds the daytime running
light relay 1 which in turn, provides power to the LH high beam lamp. Power flows through the LH high beam
lamp to the RH high beam lamp. The high beam lamps are wired in series which causes them to illuminate at
a reduced intensity. When daytime light relay 2 is open, it prevents headlamp low beam from turning on while
daytime running lights are operating.

FRONT FOG LAMP SYSTEM : System Description
INFOID:0000000012432774
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 (headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP 1 or 2 ON. The BCM
sends a front fog lamp request ON signal through 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.

INFOID:0000000012432776
TURN SIGNAL OPERATION
When the 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 output signal to the respective turn signal
lamp. The BCM sends a turn indicator signal ON request through the CAN communication lines to the combi-
nation meter. The combination meter then activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM det ects the hazard switch signal ON. The BCM outputs the
flasher output signal (right and left). The BCM sends a hazard indicator signal ON request through the CAN
communication 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 hazard lamp signal to BCM, then BCM controls hazard lamps.
Refer to DLK-25, "
REMOTE KEYLESS ENTRY FUNCTION : System Description" (with Intelligent Key sys-
tem) or DLK-199, "
REMOTE KEYLESS ENTRY SYSTEM : System Description" (without Intelligent Key sys-
tem).

PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION
When the combination switch (lighting and turn signal s witch) is in 1st position, BCM detects the LIGHTING
SWITCH 1st POSITION ON. The BCM sends a parking light ON request through the CAN communication
lines to the IPDM E/R. The IPDM E/R then activates the tail lamp relay which sends power to the parking and
instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes unless the lighting switch position is
changed. If the lighting switch position is changed, then the headlamps are turned off.
This setting can be changed by CONSULT. Refer to BCS-26, "
