HEADLAMP (HI) CIRCUIT

Description

INFOID:0000000003261559

The high beam solenoid drives the mobile valve shade. And the mobile valve shade switches the high beam
and low beam of headlamp.
• When the headlamp high relay is turned ON, magnetic force is

applied to the high beam solenoid (1) by a current. The mobile
valve shade (3) is switched to the high beam position through the
actuator rod (2).

• When the headlamp high relay is turned OFF, the current stops.

The mobile valve shade returns to the low beam position automati-
cally.

XENON HEADLAMP

Description

INFOID:0000000003261323

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

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 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.

Diagnosis Procedure

INFOID:0000000003261324

1.

CHECK XENON BULB

Install the normal bulb to the applicable headlamp. Check that the lighting switch is turned ON.

Is the headlamp turned ON?

YES

>> Replace the xenon bulb.

NO

>> GO TO 2.

2.

CHECK HID CONTROL UNIT

Install the normal HID control unit to the applicable headlamp. Check that the lighting switch is turned ON.

Is the headlamp turned ON?

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000003261329

BCM performs the high flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
The turn signal lamp blinks at normal speed when using the hazard warning lamp.

Component Function Check

INFOID:0000000003261330

1.

CHECK TURN SIGNAL LAMP

CONSULT-III ACTIVE TEST

1.

Select “FLASHER” of BCM (FLASHER) active test item.

2.

With operating the test items, check that the turn signal lamp is turned ON.

Is the turn signal lamp turned ON?

YES

>> Turn signal lamp circuit is normal.

NO

>> Refer to 

EXL-49, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003261331

1.

CHECK TURN SIGNAL LAMP BULB

Check the applicable lamp bulb.

Is the bulb normal?

YES

>> GO TO 2.

NO

>> Replace the bulb.

2.

CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE

1.

Turn the ignition switch OFF.

2.

Disconnect the front turn signal lamp connector or the rear combination lamp connector.

3.

Turn the ignition switch ON.

4.

With operating the turn signal switch, check the voltage between the BCM harness connector and the
ground.
