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.

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.

ICC System Running TestNKS004CL
NOTE:
ICC system can set VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE and CONVENTIONAL (FIXED
SPEED) CRUISE CONTROL MODE when selector lever is in “D” and “M” position.
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
NOTE:
When there is no vehicle ahead, drive at the set speed steadily.
When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.
Set Checking
1. Press the MAIN switch for less than 1.5 seconds.
2. Drive the vehicle between 40 km/h (25 MPH) and 144 km/h (90 MPH).
3. Push down the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
NOTE:
The set vehicle speed is displayed on the dot matrix LCD in the combination meter.
Check For Increase Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.
NOTE:
The maximum set speed of the vehicle-to-vehicle distance control mode is 144 km/h (90 MPH).
Check For Decrease Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:
Vehicle-to-vehicle distance control mode is automatically cancelled when the driving speed lowers to 32
km/h (20 MPH) due to the deceleration of the vehicle ahead.
The minimum set speed of the vehicle-to-vehicle distance control mode is 40 km/h (25 MPH).
Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Condi-
tion) In The Following Cases:
1. When the brake pedal is depressed after the system is turned ON.
2. When the selector lever is shifted to the “N” (Neutral) position.
3. When the MAIN switch is turned OFF.
4. When CANCEL switch is operated.
Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode Before
Cancellation
1. Cancel the system by depressing the brake pedal. Then, check if the speed before cancellation is
restored when pushing up RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N”. Then, check if the speed set before the cancella-
tion is restored when RESUME/ACCELERATE switch is pushed up.
3. Check if the speed previously set is restored when RESUME/ACCELERATE switch is operated with driv-
ing 40 km/h (25 MPH), after canceling vehicle-to-vehicle distance control mode by operating the CANCEL
switch.
