Component DescriptionINFOID:0000000001328807
CAN CommunicationINFOID:0000000001328808
CAN (Controller Area Network) is a serial communication li ne 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 eac h 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.

VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
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 the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
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.
 The set vehicle speed is displayed on the ICC system indicator 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.
NOTE:
The maximum set speed of the vehicle-to-vehicl e 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.
NOTE:
 Vehicle-to-vehicle distance control mode is automatica lly turned off 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 Condition) In The Following
Cases:
 When the brake pedal is depressed after the system is turned ON.
 When the selector lever is shifted to the “N” (Neutral) position.
 When the MAIN switch is turned OFF.
 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 foot brake. Then, check that the speed before cancellation is
restored when pressing RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N” position. Then, check if the speed set before the
cancellation is restored when RESU ME/ACCELERATE switch is pushed up.
3. Check if the speed previously set is restored w hen RESUME/ACCELERATE switch is operated with driv-
ing 40 km/h (25 MPH), after canceling vehicle-to-v ehicle 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 illuminates 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 ICC system display go off when the ignition 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).

2. Adjust the height of the target board stand so that the point of the triangle aims the cent er of the ICC sensor.
ADJUSTING THE RIGHT-LEFT POSITION OF THE TARGET
1. Attach a scale [at least 350 mm (14 in) or longer] or stick as
shown in the figure.
2. Suspend a thread with weight on the tip of the thread to 310 mm (12.2 in) left side of the target board from the center of the target
board on top.
SETTING THE TARGET
1. Suspend a thread with weight on tip to splice the cent er of the front and rear bumpers. Then, mark the
center point on the ground as each weight points.
2. Link the front and rear bumpers center points ma rked on the ground, and mark a point 5 m (16.4 ft) ahead
of the sensor, on the extended line of the previous lin k line of the bumper center points. Then, adjust the
position of the target board so that the weight come on the top of the marked point [5 m (16.4 ft) ahead of
the sensor] and face to the vehicle.
3. Adjust the position of the target board so that the extended line that links the center of the rear window glass (the center of the
rear window defogger pattern) and the center of the windshield
(the setting part of the room mirror) align with the weight sus-
pended from the board.
4. Remove the thread suspended to the left side of board and sus- pend a thread with weight on tip on the center of the target
board. Then mark the point of weight on the ground.

5. Pivot the edge of the target board 20
° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift rates the 20 ° movement.
6. Do not place anything in the space shown in the figure (view from top). NOTE:
In case the space shown in the figure is not availabl e, make space by covering the side of the target board
with a 400 mm (15.75 in)-size frosted black board or black cloth.
Aiming AdjustmentINFOID:0000000001328816
CAUTION:
Never view ICC sensor integrated unit body windo w directly during laser beam aiming adjustment.
NOTE:
Complete all necessary work for laser beam adjustment until the adjustment completes as shown in the proce-
dure. If the procedure does not complete, the ICC system is inoperable.
1. Connect CONSULT-III and select “Work Support” of “ICC”.
2. Select “LASER BEAM ADJUST”.
3. Touch “START”.
NOTE:
If the adjustment screen does not appear on the CO NSULT-III 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.
 Deformation of vehicle or the surrounding equipm ent unit, bracket, or the surrounding equipment is
causing inappropriate installation of sensor and aiming may be set out of the adjustable range.
 The area is not suitable for the adjustment work.
 ICC sensor is not clean.
 The ICC system warning lamp illuminates.
4. After the CONSULT-III displays “ADJUST THE VER TICAL OF LASER BEAM AIMING” turn the up-down
direction adjusting screw until “U/D CO RRECT” value is set in the range of ±4.

NOTE:
 Turn the screw slowly. The value change on display is slower than actual movement of the ICC sensor.
Wait for 2 seconds every time the screw is turned half a rotation.
 Turning the screw to the right lowers the aiming and to the left lifts the aiming.
5. 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.
When “COMPLETED THE VERTICAL AIMING OF LASER BEAM” appears on screen, touch “END”.
NOTE:
Be sure that the margin of “U/D CORRECT” is within ±4 with ICC sensor unit is untouched.
6. Confirm that “ADJUSTING AUTOMATIC HORIZONT AL LASER BEAM AIMING” is on screen and wait for
a while (maximum: 10 seconds).
7. Confirm that “NORMALLY COMPLETED” is disp layed on CONSULT-III and close the aiming adjustment
procedure by touching “END”.
NOTE:
Complete all the procedures once “LASER BEAM AD JUST” mode is entered in CONSULT-III. When the
procedure is discontinued, the ICC system is inoperable.
CHECK AFTER THE ADJUSTMENT
Test the ICC system operation by running test. Refer to ACS-11, "ICC System Running Test".
