HEADLAMP ASSEMBLY
HEADLAMP ASSEMBLY : Xenon Headlamp
INFOID:0000000012201609
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*
1
ECM transmits engine status signal to BCM via CAN communication.

[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.
For the details of HID control unit and the xenon headlamp, refer to
EXL-9, "HEADLAMP ASSEMBLY : Xenon

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
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
