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.

Automatically turns ON/OFF parking lamps and the headlamps in accordance with ambient light.
Timing for when the lamps turn ON/OFF can be selected using four modes.
OUTLINE
The auto light control system has an optical s ensor inside it that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking lamps and the head-
lamps in accordance with the ambient li ght. Sensitivity can be adjusted in four steps. For the details of the set-
ting, Refer to LT-55, "
Preliminary Check".
Optical sensor control mode can be changed by the function setting of CONSULT-III or display.
Optical sensor, power is supplied
 from BCM (body control module) terminal 17
 to optical sensor terminal 1.
Optical sensor, ground is supplied
 to optical sensor terminal 3
 through BCM terminal 18.
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied
 from optical sensor terminal 2
 to BCM terminal 14

COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM ac tivates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turn ing the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minute timer and a 45 second timer
 When opening any door (door switch is ON), the 5 mi nute timer starts and then headlamps go out 5 minutes
later
 When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then headlamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 second timer is in operation, the
5 minute timer starts again
 The timer stops when turning on the ignition switch or turning off the auto light switch under the above condi-
tions.
Delay timer control mode can be changed by the f unction setting of CONSULT-III or display.
CAN Communication System DescriptionINFOID:0000000001328308
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitINFOID:0000000001328309
Refer to LAN-43, "CAN System Specification Chart".
Major Component and FunctionsINFOID:0000000001328310
Components Functions
BCM  Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch (AUTO),
driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor  Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2,500 lux)
