through grounds E1 and E31.
With power and ground supplied, low beam headlamp and high beam headlamp illuminate.
Unified meter and A/C amp. receives high beam request signal (ON) through CAN communication, and makes
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. IPDM E/R supplies power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 1,
through 15A fuse (No. 86, located in IPDM E/R)

to front combination lamp RH and LH terminals 5, and
to front combination lamp RH and LH terminals 10
through grounds E1 and E31.
With power and ground supplied, low beam headlamp and high beam headlamp illuminate.
Unified meter and A/C amp. receives high beam request signal (ON) through CAN communication, and makes
high beam indicator lamp turn ON in combination meter.

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.

FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), BCM detects FR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by
BCM combination switch reading function. And then, BCM sends front fog lamp request signal (ON) through
CAN communication.
When receiving front fog lamp request signal (ON), IPDM E/R turns ON front fog lamp relay in IPDM E/R. And
then, front fog lamp go ON. IPDM E/R supplies power
through IPDM E/R terminal 36
to front fog lamp RH terminal 1,
through IPDM E/R terminal 37
to front fog lamp LH terminal 1.
Ground is supplied
