through grounds M71 and M72.
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
