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-34, "CAN Communication Unit" .
ComponentVehicle-to-

control modeConventional
(fixed speed)
cruise
control modeBrake assist
(with pre-
view func-
tion)Description
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.

ACTION TEST
Revision: 2006 January2006 M35/M45
ACTION TESTPFP:00000
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 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
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 MPH (1 km/h for CANADA models) as RESUME/ACCELERATE
switch is pushed up.
NOTE:
The maximum set speed of the vehicle-to-vehicle distance control mode is 90 MPH (144 km/h for CANADA
models).
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 MPH (1 km/h for CANADA models) as SET/COAST switch is
pushed down.
NOTE:
Vehicle-to-vehicle distance control mode is automatically cancelled when the driving speed lowers to 20
MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.
The minimum set speed of the vehicle-to-vehicle distance control mode is 25 MPH (40 km/h for CANADA
models).
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 25 MPH (40 km/h for CANADA models)
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 25 MPH (40 km/h for CANADA models), after canceling vehicle-to-vehicle distance control mode by
operating the CANCEL switch.

Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. Vehicle-to-vehicle distance control mode is displayed in combi-
nation meter and “CRUISE” is illuminated when MAIN switch is
pressed “ON” for less than 1.5 seconds and ready for operation.
The illumination goes off when MAIN switch is turned to OFF.
3. “CRUISE” illumination and dot matrix LCD go off when the igni-
tion switch is turned to OFF while MAIN switch is ON (“CRUISE”
illumination is ON and vehicle-to-vehicle distance control mode
is ready for operation).
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.
Check For Distance Switch
1. Start engine.
2. Press the MAIN switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(Long)
(Middle)(Short).
NOTE:
The set distance indicator shows (Long) immediately after the engine starts.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Set Checking
1. Press the MAIN switch for more than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push down the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.

6. Touch “LASER BEAM ADJUST”.
7. Touch “START”.
CAUTION:
If the adjustment screen does not appear on the CONSULT-
II screen in 10 seconds. After touching “LASER BEAM
ADJUST” screen, the following causes may be considered:
Target is not set accurately.
There is not enough space beside the target.
The range of laser beam aiming exceeds for improper
installation position.
–Deformation of vehicle body.
–Deformation of unit.
–Deformation of bracket.
The area is not suitable for the adjustment work.
ICC sensor integrated unit is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the up-down direction adjusting
screw until “U/D CORRECT” value is set in the range of
4.
CAUTION:
Turn the screw slowly. The value change on display is
slower than actual movement of the ICC sensor integrated
unit. Wait for 2 seconds every time the screw is turned half
a rotation.
NOTE:
Turning the screw clockwise to laser beam is downward and
counterclockwise to laser beam is upward.
9. When “U/D CORRECT” value indicates
4, confirm that the margin of value remains within 4 at least for
2 seconds with no equipment or hand touching the ICC sensor integrated unit.

LASER BEAM AIMING ADJUSTMENT
Revision: 2006 January2006 M35/M45
When “COMPLETED THE VERTICAL AIMING OF LASER
BEAM” appears on screen, touch “END”.
CAUTION:
Be sure that the margin of “U/D CORRECT” is within
4 with
ICC sensor integrated unit is untouched.
10. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER
BEAM AIMING” is on screen and wait for a while (maximum: 10
seconds).
11. Confirm that “NORMALLY COMPLETED” is displayed on CON-
SULT-II and close the aiming adjustment procedure by touching
“END”.
CAUTION:
Complete all the procedures once “LASER BEAM ADJUST”
mode is entered in CONSULT-II. When the procedure is dis-
continued, the ICC system is inoperable.
CHECK AFTER THE ADJUSTMENT
Test the ICC system operation by ICC system running test. Refer to ACS-10, "ICC System Running Test" .
