HEADLAMP SYSTEM : System Description

INFOID:0000000009175334

LOW BEAM OPERATION

When the lighting switch is in the AUTO (if equipped and activated) or headlamp position, the BCM receives

input requesting the headlamps to illuminate. This input is communicated to the IPDM E/R across 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 AUTO (if equipped and activated) or headlamp 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 signal to the BCM. This input is communicated to the IPDM E/R across

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) through the CAN communication lines and

turns the high beam indicator lamp ON.

EXTERIOR LAMP BATTERY SAVER CONTROL

With the combination switch (lighting and turn signal switch) in the AUTO (if equipped and activated) parking

lamp or headlamp 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 45 seconds, unless the lighting switch position is

changed. If the lighting switch position is changed, then the headlamps are turned off.

AUTO LIGHT SYSTEM : System Diagram

AUTO LIGHT SYSTEM : System Description

INFOID:0000000009175336

• BCM (Body Control Module) controls auto light operation according to signals from optical sensor, lighting

switch and ignition switch.

• IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, tail, front fog

lamps and headlamps according to CAN communication signals from BCM.

• Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to volt-

age, then sends the optical sensor signal to BCM.

OUTLINE

The auto light control system has an optical sensor that detects outside brightness.

When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail,

front fog lamps and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps.

For the details of the setting, Refer to 

BCS-18, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"

.

WIPER LINKED AUTO LIGHTING FUNCTION (if equipped)

With the lighting switch in the AUTO position, the BCM will turn on the exterior lamps after detecting 4 opera-

tions of the front wiper. The BCM will turn off the exterior lamps 3 seconds after the front wiper switch is turned

to the OFF position.

DAYTIME RUNNING LIGHT SYSTEM : System Description

INFOID:0000000009175338

System Description

The daytime light system is equipped with a daytime light control that activates the daytime lights within the

front fog lamp assembly when the engine is operating. If the parking brake is applied, the daytime lights will

turn OFF. The daytime lights will turn ON when the parking brake is released. 

OPERATION 

The BCM monitors inputs from the parking brake switch and the combination switch (lighting and turn signal

switch) to determine when to operate 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 daytime lights.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM : System Description

INFOID:0000000009175340

TURN SIGNAL OPERATION

When the combination switch (lighting and turn signal switch) is in LH or RH turn position with the ignition

switch in the ON position, the BCM receives input requesting the turn RH or turn LH lamps to illuminate. The

BCM controls the turn signal power to the respective turn signal lamp. The BCM also sends a turn indicator

signal ON request via the CAN communication lines to the combination meter. The combination meter then

activates the appropriate turn signal indicator and audible buzzer.

HAZARD LAMP OPERATION

When the hazard switch is in the ON position, the BCM receives input requesting the hazard lamps illuminate.

The BCM controls the turn signal power to both the LH and RH turn signal lamps. The BCM sends a hazard

indicator signal ON request via the CAN communication lines to the combination meter. The combination

meter then activates both the LH and RH turn signal indicators and audible buzzer.

scription

INFOID:0000000009175342

PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION

With the lighting switch is in the AUTO (if equipped and activated) or parking lamp position, the BCM receives

input requesting the parking lamps to illuminate. The BCM sends a parking light ON request via the CAN com-

munication 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 AUTO (if equipped and activated) or park-

ing lamp position and the ignition switch is turned from ON or ACC to OFF, the battery saver feature is acti-

vated.

Under this condition, the exterior lamps remain illuminated for 45 seconds unless the lighting switch position is

changed. If the lighting switch position is changed, then the exterior lamps are turned off.

FRONT FOG LAMP SYSTEM : System Description

INFOID:0000000009175344

The front fog lamps are activated with the combination switch (lighting and turn signal switch). The lighting

switch signal to the BCM is monitored with the BCM combination switch reading function. When the fog lamps

are turned ON with the lighting 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.
