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,
to rear combination lamp LH 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 (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
to BCM terminal 29
through hazard switch terminal 2,
to hazard switch terminal 1

through grounds E1 and E31,
to rear combination lamp RH and LH terminals 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 and LH) through CAN communication, then
makes turn (RH and LH) indicator start flashing operation interlocked with the buzzer sounds in combination
meter.
With power and ground supplied, BCM controls the blinking of the hazard warning lamp.
INTERLOCKED HAZARD LAMP OPERATION WITH REMOTE KEYLESS ENTRY SYSTEM
BCM receives the keyfob signal (door lock/unlock signal) from remote keyless entry receiver, then BCM con-
trols hazard lamps.
Refer to BL-46, "
REMOTE KEYLESS ENTRY SYSTEM" .
INTERLOCKED HAZARD LAMP OPERATION WITH INTELLIGENT KEY SYSTEM
BCM receives the door lock/unlock signal from Intelligent Key unit through CAN communication, then BCM
controls hazard lamps.
Refer to BL-68, "
INTELLIGENT KEY SYSTEM" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionBKS001PO
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.
CAN Communication UnitBKS001PP
Refer to LAN-49, "CAN System Specification Chart" .
