HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
Revision: November 20092006 QX56
System DescriptionEKS00B8E
Daytime light system turns on daytime light lamps while driving. Daytime light lamps are not turned on if
engine is activated with parking brake applied. Release parking brake to turn on daytime light lamps. The
lamps turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when light-
ing switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.
OUTLINE
Power is supplied at all times

to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room), and

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through 20A fuse (No. 53, located in the IPDM E/R)

to CPU (central processing unit) of the IPDM E/R, and

through 10A fuse [No. 19, located in the fuse block (J/B)]

to combination meter terminal 8, and

through 10A fuse (No. 45, located in the IPDM E/R)

to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied

to ignition relay, located in the IPDM E/R, and

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38, and

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 24.
Ground is supplied

to BCM terminal 67 and

to combination meter terminal 17

through grounds M57, M61 and M79.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU of the IPDM E/R controls the daytime light relay coil. When energized, this relay
directs power

through daytime light relay terminal 3

to front combination lamp LH terminal 2

through front combination lamp LH terminal 6

to IPDM E/R terminal 55

through 10A fuse (No. 35, located in the IPDM E/R)

through 10A fuse (No. 34, located in the IPDM E/R)

through IPDM E/R terminal 56

to front combination lamp RH terminal 6.
Ground is supplied

to front combination lamp RH terminal 2

through grounds E9, E15 and E24.
With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
COMBINATION SWITCH READING FUNCTION

AUTO LIGHT SYSTEM
Revision: November 20092006 QX56
System DescriptionEKS00B8S
Automatically turns on/off the 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 uses an optical sensor 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 light. Sensitivity can be adjusted in four steps. For the details of the set-
ting, refer to LT- 5 5 , "
SETTING CHANGE FUNCTIONS" .
Optical sensor ground is supplied

to optical sensor terminal 3

through BCM (body control module) terminal 18.
When ignition switch is turned to “ON” position and when outside brightness is darker than prescribed level,
input is supplied

to BCM terminal 58

through optical sensor terminal 4.
The headlamps will then illuminate. For a description of headlamp operation, refer to LT- 5 , "
System Descrip-
tion" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned from
ON or ACC to OFF, and one of the front doors is opened, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
DELAY TIMER FUNCTION
When the ignition switch is ON and auto light switch is ON, the BCM turns on/off the headlamps. In delay timer
function, ignition is OFF, auto light sensor power source is OFF and the headlamps are not turned on/off by the
BCM. On condition that:

when the state of ignition switch ON or ACC is ON and output judgment by auto light function is headlamp
ON changes to ignition switch and ACC are OFF and any door switch is ON, output judgment by BCM
should be headlamp ON for 5 minutes by timer. After time out, output judgment by BCM should be head-
lamp OFF.

when the state of any door switch is turned to ON from OFF while 45 second or 5 minute timer is counting,
timer stops, and restarts counting for 5 minutes, then BCM judges output as headlamp ON. After time out,
BCM judges output as headlamp OFF.

when the state of front door switch (LH), front door switch (RH), rear door switch LH, rear door switch RH
or back door latch (door ajar switch) is ON turns to all door switches are OFF while 45 second or 5 minute
timer is counting, timer stops, and restarts counting for 45 seconds, then BCM judges output as headlamp
ON. After timer out, BCM judges output as headlamp OFF.

when the state is ignition switch ON or ACC is ON or auto light switch OFF while timer is counting, timer
stops counting and BCM turns on/off lamps according to headlamp function, front fog lamp function, auto
light function and headlamp battery save function.
Delay timer control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionEKS00B8T
Refer to LAN-26, "CAN COMMUNICATION" .
Major Components and FunctionsEKS00B8U
Components Functions
BCM

Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch
(AUTO), front door switch LH, front door switch RH, rear door switch, back door latch (door ajar
switch), and ignition switch (ON, OFF).
Optical sensor

Converts ambient light (lux) to voltage, and sends it to BCM. (Detects lightness of 50 to 1,300 lux)
