When the turn signal switch is moved to the left positi on, BCM output turn signal from BCM terminal 45, inter-
preting it as turn signal is ON.
Connected from BCM terminal 45 to front combination lamp LH terminal 4.
Turn signal lamp turns ON
through front combination lamp LH terminal 8
to grounds E21, E50 and E51.
Connected from BCM terminal 45 to rear co mbination lamp control unit terminal 4.
Rear turn signal (LED) turns ON
through rear combination lamp control unit terminal 11
to rear combination lamp LH terminal 3,
through rear combination lamp LH terminal 4
to rear combination lamp control unit terminal 10.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
RH Turn Signal Lamp
When the turn signal switch is moved to right position, BCM output turn signal from BCM terminal 46, interpret-
ing it as turn signal is ON.
Connected from BCM terminal 46 to front combination lamp RH terminal 4.
Turn signal lamp turns ON
through front combination lamp RH terminal 8
to grounds E21, E50 and E51.
Connected form BCM terminal 46 to rear co mbination lamp control unit terminal 5.
Rear turn signal (LED) turns ON
through rear combination lamp control unit terminal 9
to rear combination lamp RH terminal 3,
through rear combination lamp RH terminal 4
to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
HAZARD LAMP OPERATION
When the hazard switch is depressed, BCM output turn signal from BCM terminals 45 and 46, interpreting it as
turn signal is ON.
Connected from BCM terminal 45 and 46 to front combination lamp RH and LH terminals 4.
Turn signal lamp turns ON
through front combination lamp RH and LH terminals 8
to grounds E21, E50 and E51.
Connected form BCM terminals 45 and 46 to rear combination lamp control unit terminals 4 and 5.
Rear turn signal (LED) turns ON
through rear combination lamp control unit terminal 11
to rear combination lamp LH terminal 3,
through rear combination lamp LH terminal 4
to rear combination lamp control unit terminal 10,
through rear combination lamp control unit terminal 9
to rear combination lamp RH terminal 3,
through rear combination lamp RH terminal 4
to rear combination lamp control unit terminal 8.
And hazard switch is depr essed, ground is supplied
to hazard switch terminal 2
through BCM terminal 29,
to grounds M35, M45 and M85
through hazard switch terminal 1.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.

TURN SIGNAL AND HAZARD WARNING LAMPS
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends s\
ignal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
REMOTE CONTROL ENTRY SYSTEM OPERATION
When the remote control entry system is triggered by i nput from key fob, BCM output turn signal from BCM
terminals 45 and 46, interpreting it as turn signal is ON.
Connected from BCM terminals 45 and 46 to front combination lamp RH and LH terminals 4.
Turn signal lamp turns ON
through front combination lamp RH and LH terminals 8
to grounds E21, E50 and E51.
Connected form BCM terminals 45 and 46 to rear combination lamp control unit terminals 4 and 5.
Rear turn signal (LED) turns ON
through rear combination lamp control unit terminal 11
to rear combination lamp LH terminal 3,
through rear combination lamp LH terminal 4
to rear combination lamp control unit terminal 10,
through rear combination lamp control unit terminal 9
to rear combination lamp RH terminal 3,
through rear combination lamp RH terminal 4
to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through the CAN communication, and turns ON turn sig-
nal indicator lamp with combination meter.
With power and input supplied, BCM controls the flashing of hazard warning lamps when key fob is used to
activate remote control entry system.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
CAN Communication System DescriptionINFOID:0000000001328345
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 s peed 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 CA N 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 UnitINFOID:0000000001328346
Refer to LAN-43, "CAN System Specification Chart".

CAUTION:
Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
Turn wiper intermittent dial posi tion to 4 except when checking wavef orm or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-III. Refer to LT-
103, "CONSULT-III Functions (BCM)".
