Components DescriptionNKS004CH
CAN CommunicationNKS004CI
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-
tric 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 UNIT
Refer to LAN-52, "CAN Communication Signal Chart" .

ICC sensor integrated unit×××

Controls vehicle distance by operating electric throttle
control actuator based on that sensor signals and
CAN communication data.

Controls vehicle distance by transmitting deceleration
degree commandment value signal to ABS actuator
and electric unit (control unit) when deceleration with
brake is needed.

Irradiates laser beam, and receives reflected laser
beam to measure distance from preceding vehicle.
ECM×××Transmits accelerator pedal position signal, ICC brake
switch signal, stop lamp switch signal and ICC steering
switch signal to ICC sensor integrated unit through CAN
communication.
ABS actuator and electric
unit (control unit)×××

Transmits vehicle speed signal (wheel speed) and
stop lamp switch signal to ICC sensor integrated unit
through CAN communication.

Receives deceleration degree commandment value
signal from ICC sensor integrated unit, and controls
brake fluid pressure with the ABS motor.
BCM×Transmits front wiper request signal to ICC sensor inte-
grated unit through CAN communication.
TCM××Transmits gear position signal and output shaft revolu-
tion signal to ICC sensor integrated unit through CAN
communication.
Unified meter and A/C amp.×××Receives meter display signal, ICC warning lamp signal
and buzzer output signal from ICC sensor integrated
unit through CAN communication.
ICC brake switch×××Transmits operating signal to ECM when depressing
brake pedal. ICC sensor integrated unit cancels cruise
system at driver's brake operation.
Stop lamp switch×××Transmits operating signal to ECM and ABS actuator
and electric unit (control unit) when depressing brake
pedal. ICC sensor integrated unit cancels cruise system
at driver's brake operation.
