VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-163.
XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps . Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.
The light produced by the headlamps is white color si milar to sunlight that is easy to the eyes.
Light output is nearly double that of halogen headl amps, affording increased area of illumination.
Counter-reflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.
Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionINFOID:0000000001328267
CAN (Controller Area Network) is a serial communication li ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed 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 CAN 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.

DAYTIME LIGHT OPERATION
Once the parking brake is turned OFF after ignition swit ch ON, if the lighting switch is turned OFF while engine
running, the BCM sends daytime light r equest signal (ON) through CAN communication.
When receiving daytime light request signal (ON), combi nation meter turns ON daytime light relay. And power
is supplied
through daytime light relay terminal 1
to combination meter terminal 10,
through daytime light relay terminal 3
to parking lamp RH and LH terminals 1.
Ground is supplied
