Optical Sensor

INFOID:0000000009653006

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

Daytime Running Light Relay

INFOID:0000000009653007

Headlamp HI ground circuit is switched according to request from IPDM E/R.

Xenon Headlamp

INFOID:0000000009653008

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.

[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, for preventing

electrical shock.

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

when checking ON/OFF status, for preventing electrical shock.

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

ness connector.

• Check for fusing 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.

Hazard Switch

INFOID:0000000009653009

Inputs the hazard switch ON/OFF signal to BCM.

Headlamp Aiming Switch

INFOID:0000000009653010

Adjusts height of headlamp aiming.

HID control unit

INFOID:0000000009653011

Headlamp (LO) circuit is connected to HID control unit integrated in the headlamp. Headlamp (LO) circuit turns
xenon headlamp ON.
For the details of HID control unit and the xenon headlamp, refer to 

EXL-9, "Xenon Headlamp"

.

Headlamp Aiming Motor

INFOID:0000000009653012

The headlamp levelizer adjusts the headlamp light axis upward and downward with the headlamp aiming
motor integrated in the front combination lamp.
