TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: 2006 July 2007 FX35/FX45

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 depressed, 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.
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.
REMOTE CONTROL ENTRY SYSTEM OPERATION
When the remote control entry system is triggered by input 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-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS002XE
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.
