LT-6
< SERVICE INFORMATION >
HEADLAMP - XENON TYPE -
to combination meter terminal 7.
With ignition switch in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminals 49 and 52
through grounds M35, M45 and M85,
to IPDM E/R terminals 38 and 60
through grounds E21, E50 and E51,
to combination meter terminals 5, 6 and 15
through grounds M35, M45 and M85.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IP DM E/R through the CAN communication lines. The CPU
located in the IPDM E/R controls the headlamp lo w relay coil, which when energized, directs power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 6,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 6.
Ground is supplied
to front combination lamp RH and LH terminals 7
through grounds E21, E50 and E51,
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the HIGH or PASS position, the BCM receives input
signal requesting the headlamp high beams to illuminate. Th is input signal is communicated to the IPDM E/R
through the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil and low relay coil, which when energized, directs power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 6,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 6,
through 10A fuse (No. 72, located in IPDM E/R)
through IPDM E/R terminal 27
to front combination lamp RH terminal 5,
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 5.
Ground is supplied
to front combination lamp RH and LH terminals 7
through grounds E21, E50 and E51,
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
The unified meter and A/C amp. that received the hi gh beam request signal by BCM through the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illumi nated for 5 minutes, then the headlamps are turned OFF.

General Information for Xenon Headlamp Trouble DiagnosisINFOID:0000000001328284
In most cases, malfunction of xenon headlamp - “does not ill uminate”, “flickers” or “dark” - is caused by a mal-
functioning xenon bulb. A malfunctioning HID control unit or lamp housing, however, may be a cause. Be sure
to perform trouble diagnosis following the steps described below.
Caution:INFOID:0000000001328285
Installation or removal of connector must be done with lighting switch OFF.
Disconnect the battery cable from the negative terminal or remove power fuse.
When the lamp is illuminated (when lighting switch is ON), never touch harness, HID control unit, inside of
lamp, or lamp metal parts.
To check illumination, temporarily install lamp in vehicle. Be sure to connect power at vehicle side connector.
If error can be traced directly to electrical system, fi rst check for items such as blown fuses and fusible links,
broken wires or loose connectors, dislocated terminals, and improper connections.
Never work with wet hands.
Using a tester for HID control unit circuit trouble diagnosis is prohibited.
Disassembling HID control unit or harnesses ( bulb socket harness, ECM harness) is prohibited.
Immediately after illumination, light intensity and color will fluctuate, but there is nothing wrong.
When bulb has come to end of its life, brightness will dr op significantly, it will flash repeatedly, or light color
will turn reddish. 30 – 6 : Continuity should exist.
