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.

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)".
