OUTLINE

• The lamp light source is by the arch discharge by applying high voltage into the xenon gas-filled bulb instead

of the halogen bulb filament.

• Sight becomes more natural and brighter because the amount of light are gained adequately and the color of

light is sunshine-like white.

• The xenon bulb drops the amount of light, repeats blinking, and illuminates in red if the bulb reaches the ser-

vice life.

ILLUMINATION PRINCIPLE

Part

Description

BCM

• Detects each switch condition by the combination switch reading function
• Judges that the headlamp is turned ON according to the vehicle condition
• Requests the headlamp relay (High/Low) ON to IPDM E/R (via CAN communication)
• Requests the high beam indicator lamp and position lamp indicator lamp ON to the

combination meter (via CAN communication)

• Judges the outside brightness from the optical sensor signal.
• Judges the ON/OFF status of the exterior lamp from the outside brightness and the

vehicle condition.

IPDM E/R

Controls the integrated relay and daytime running light relay, and supplies voltage to the
load according to the request from BCM (via CAN communication).

Combination meter

• Turns the high beam indicator lamp and position lamp indicator lamp ON according

to the request from BCM (via CAN communication).

• Blinks the turn signal indicator lamp and outputs the turn signal operating sound with

integrated buzzer according to the request from BCM (via CAN communication).

• Combination meter transmits parking brake switch signal to BCM via CAN communi-

cation.

ECM*

ECM transmits engine status signal to BCM via CAN communication.

Headlamp assembly

HID control unit

Refer to

EXL-10, "HEADLAMP ASSEMBLY : HID control unit"

Xenon headlamp

Refer to

EXL-9, "HEADLAMP ASSEMBLY : Xenon Headlamp"

Optical sensor*

Optical sensor converts the outside brightness (lux) to voltage and transmits the optical
sensor signal to BCM.

Door switch

DLK-10, "Component Description"

Combination switch
(Lighting & turn signal switch)

Refer to

BCS-8, "COMBINATION SWITCH READING SYSTEM : System Description"

Hazard switch

Inputs the hazard switch ON/OFF signal to BCM.

[XENON TYPE]

COMPONENT PARTS

1. Discharging starts in high voltage pulse between bulb elec-

trodes.

2. Xenon gas is activated by current between electrodes. Pale light

is emitted.

3. The luminous tube (bulb) temperature elevates. Evaporated

halide is activated by discharge. The color of light changes into

white.

NOTE:

• Brightness and the color of light may change slightly immediately

after the headlamp turned ON until the xenon bulb becomes sta-

ble. This is not malfunction.

• Illumination time lag may occur between right and left. This is not

malfunction.

PRECAUTIONS FOR TROUBLE DIAGNOSIS

Representative malfunction examples are; “Light does not turn ON”, “Light blinks”, and “Brightness is inade-

quate.” The cause often be the xenon bulb. Such malfunctions, however, are occurred occasionally by HID

control unit malfunction or lamp case malfunction. Specify the malfunctioning part with diagnosis procedure.

WARNING:

• Never touch the harness, HID control unit, the inside and metal part of lamp when turning the head-

lamp ON or operating the lighting switch.

• Never work with wet hands.

CAUTION:

• Never perform HID control unit circuit diagnosis with a circuit tester or an equivalent.

• Temporarily install the headlamps on the vehicle. Connect the battery to the connector (vehicle side)

when checking ON/OFF status.

• Disconnect the battery negative terminal before disconnecting the lamp socket connector or the har-

ness connector.

• Check for blown (open) of the fusible link(s), open around connector, short, disconnection if the

symptom is caused by electric error.

NOTE:

• Turn the switch OFF once before turning ON, if the ON/OFF is inoperative.

• The xenon bulb drops the amount of light, repeats blinking, and illuminates in red if the bulb reaches the ser-

vice life.

HEADLAMP ASSEMBLY : HID control unit

INFOID:0000000012201610

Headlamp (LO) circuit is connected to HID control unit integrated in the headlamp. Headlamp (LO) circuit turns

xenon headlamp ON.

HEADLAMP SYSTEM : System Description

INFOID:0000000012201612

OUTLINE

Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and

relay control function of IPDM E/R.

HEADLAMP (LO) OPERATION

• BCM detects the combination switch condition with the combination switch reading function.

• BCM transmits the low beam request signal to IPDM E/R via CAN communication according to the head-

lamp (LO) ON condition.

Headlamp (LO) ON condition

- Lighting switch 2ND

- Lighting switch AUTO (Only when the illumination judgment by auto light system is ON. For details, refer to

EXL-12, "AUTO LIGHT SYSTEM : System Description"

- Lighting switch PASS

• IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp (LO) ON according to the

low beam request signal.

HEADLAMP (HI) OPERATION

• BCM transmits the high beam request signal to IPDM E/R and the combination meter via CAN communica-

tion according to the headlamp (HI) ON condition.

Headlamp (HI) ON condition

- Lighting switch HI with the lighting switch 2ND

- Lighting switch HI with the lighting switch AUTO (Only when the illumination judgment by auto light system is

ON. For details, refer to

EXL-12, "AUTO LIGHT SYSTEM : System Description"

- Lighting switch PASS

• Combination meter turns the high beam indicator lamp ON according to the high beam request signal.

• IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp (HI) ON according to the

high beam request signal.

FOLLOW ME HOME FUNCTION

When the driver is moving to the house entrance from the own vehicle, headlamp is kept still ON by the follow

me home function of BCM.

• When BCM detects the input of lighting switch PASS while all of following conditions satisfied, it transmits

the low beam request signal for a period of time to IPDM E/R through CAN communication.

Follow me home ON condition

- Ignition switch OFF
