HEADLAMP - XENON TYPE -

Ground is supplied

to front combination lamp RH and LH terminals 5, and

to front combination lamp RH and LH terminals 4

through grounds E1 and E31.
With power and ground supplied, high beam headlamp illuminates.
The unified meter and A/C amp. receives high beam request signal (ON) through CAN communication, and
make high beam indicator lamp turn ON in combination meter.
FLASH-TO-PASS OPERATION
When the lighting switch is in PASSING position, BCM detects the PASSING (ON) by BCM combination switch
reading function. BCM sends low beam request signal (ON) and high beam request signal (ON) through CAN
communication.
When receiving low beam request signal (ON) and high beam request signal (ON), IPDM E/R turns ON head-
lamp low relay and headlamp high relay in IPDM E/R. And then, headlamp bulbs go ON. High beam solenoids
move the bulb shades in the front combination lamps to change beams from/to high and low. IPDM E/R sup-
plies power

CAN Communication System DescriptionBKS001NL
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 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.
