HEADLAMP
A Xenon type headlamp is adapted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is pa ssed between two tungsten electrodes through a mixture
of Xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control
of the power supply gives the headlamps stable quality and tone color. Following are some of the advantages
of the Xenon type headlamp.
• The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headlamps, affording increased area of illumination.
• The light features a high relative spectral distribution at wavelengths to which the human eye is most sensi- tive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.
• Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
With the combination switch (lighting and turn signal switch) in the 2ND 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 via the CAN
communication lines. The CPU of the combination meter c ontrols the ON/OFF status off the HIGH BEAM indi-
cator. The CPU of the IPDM E/R controls the headlamp LH high and RH high relay coils which supplies power
to the high beam headlamps.
The combination meter receives a high beam request signal (ON) via the CAN communication lines and turns
the high beam indicator lamp ON.

TURN SIGNAL LAMP CIRCUIT
TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000003776190
The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The
BCM outputs voltage direction to the left and right turn signals during turn signal operation or both during haz-
ard warning operation. The BCM sends a turn signal indicator request to the combination meter via the CAN
communication lines.
The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
Turn signal lamp blinks at normal speed when using the hazard warning lamp.
Component Function CheckINFOID:0000000003776191
1.CHECK TURN SIGNAL LAMP
CONSULT-III
1. Select "FLASHER" of BCM (FLASHER) active test item.
2. With operating the test items, check that the turn signal lamp blinks.
Does the turn signal lamp blink?
YES >> Turn signal lamp circuit is normal.
NO >> Refer to EXL-46, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003776192
1.CHECK TURN SIGNAL LAMP BULB
Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?
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/fog lamp connector or the rear combi- nation lamp connector.
3. Turn the ignition switch ON.
4. With turn signal switch operating, check the voltage between the BCM harness connector M20 and ground.
Is voltage reading as specified?
YES >> GO TO 3.
NO >> Replace BCM. Refer to BCS-56, "
Removal and Installation".
