REAR FOG LAMP OPERATION
When the lighting switch is in rear fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), BCM detects RR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by
BCM combination switch reading function. And then, BCM sends rear fog lamp request signal (ON) through
CAN communication.
When receiving rear fog lamp request signal (ON), BCM supplies power

through BCM terminal 67

to rear fog lamp terminal 1.
Ground is supplied

to rear fog lamp terminal 2

through grounds B16 and B17.
With power and ground supplied, the rear fog lamp illuminates.
Unified meter and A/C amp. receives rear fog lamp request signal (ON) through CAN communication, and
make rear fog lamp indicator go ON in combination meter.
COMBINATION SWITCH READING FUNCTION

EXTERIOR LAMP BATTERY SAVER CONTROL
Refer to LT- 1 9 7 , "EXTERIOR LAMP BATTERY SAVER CONTROL" .
CAN Communication System DescriptionBKS001PA
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.

TURN SIGNAL OPERATION
Turn Signal Lamp RH
When the turn signal switch is in RH position with the ignition switch in ON position, BCM detects the TURN
RH (ON) by BCM combination switch reading function. BCM outputs the flasher output signal (right) to turn
signal lamp RH intermittently. And then, turn signal lamp RH start flashing operation. BCM sends turn indicator
signal (RH) through CAN communication. BCM supplies power

through BCM terminal 46

to front combination lamp RH terminal 8

to side turn signal lamp RH terminal 1 and

to rear combination lamp RH terminal 1.
Ground is supplied

to front combination lamp RH terminal 4 and

to side turn signal lamp RH terminal 2

through grounds E1 and E31,

to rear combination lamp RH terminal 2

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17 (without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (RH) through CAN communication, then makes
turn RH indicator start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the blinking of the turn signal lamp RH.
Turn Signal Lamp LH
When the turn signal switch is in LH position with the ignition switch in ON position, BCM detects the TURN LH
(ON) by BCM combination switch reading function. BCM outputs the flasher output signal (left) to turn signal
lamp LH intermittently. And then, turn signal lamp LH start flashing operation. BCM sends turn indicator signal
(LH) through CAN communication. BCM supplies power

through BCM terminal 45

to front combination lamp LH terminal 8

to side turn signal lamp LH terminal 1 and

to rear combination lamp LH terminal 1.
Ground is supplied

to front combination lamp LH terminal 4 and

to side turn signal lamp LH terminal 2

through grounds E1 and E31,

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17 (without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (LH) through CAN communication, then makes
turn LH indicator start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the blinking of the turn signal lamp LH.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, BCM detects the hazard switch signal ON. BCM outputs the flasher
output signal (right) and flasher output signal (left) to turn signal lamp (RH and LH) intermittently. And then turn
signal lamp (RH and LH) start flashing operation. And BCM sends turn indicator signal (RH and LH) through
CAN communication. Hazard switch supplies ground
