5.CHECK THE ICC TARGET BOARD INSTALLATION AREA
Do not place anything other than ICC target board in the space shown in the figure (view from top).
NOTE:
In case the space shown in the figure is not avail able, cover the side of the ICC target board with a 1400
mm(4.6 ft)-size frosted black board or black cloth.

Work Procedure (Laser Beam Aiming Adjustment)".
Work Procedure (Laser B eam Aiming Adjustment)INFOID:0000000006224296
DESCRIPTION
Adjust the laser beam aiming in a vertical di rection with CONSULT-III as per the following.
The laser beam aiming adjustment in a horizontal dire ction is performed automatically with CONSULT-III.
CAUTION:
Never look directly into the laser beam source (ICC sensor body window) during laser beam aiming
adjustment.
Perform all necessary work for laser beam aiming adjustment until the adjustment completes as
shown in the procedure. If the procedure do es not complete, the ICC system is inoperable.
1.SET CONSULT-III TO THE LASER BEAM AIMING ADJUSTMENT MODE
1. Start the engine.
2. Connect CONSULT-III and select “Work support” of “LASER”.
3. Select “LASER BEAM ADJUST” after t he “Work support” screen is displayed.
4. Select “START” after the “LASER BEAM ADJUST” screen is displayed.
NOTE:
If the adjustment screen does not appear within approx imately 10 seconds after “LASER BEAM ADJUST”
is selected, the following causes are possible.
The ICC target board is not installed in the correct position.
Adequate space is not secured around the ICC target board.
The laser beam aiming adjustment exceeds its proper installation range.
- Deformation of vehicle body.
- Deformation of unit.
- Deformation of bracket.
The area is not suitable for the adjustment work.
ICC sensor body window is not clean.
The ICC system warning lamp illuminates.
>> GO TO 2.
2.LASER BEAM AIMING ADJUSTMENT
After “ADJUST THE VERTICAL OF LASER BEAM AIMI NG” is displayed on CONSULT-III screen, adjust by
turning the up-down direction adjusting screw until “U/D CORRECT” becomes ±4 or less.

>> GO TO 7.
7.SET CHECKING (2)
1. Stop the vehicle.
2. Drive the vehicle at less than approximately 32 km/h (20 MPH).
3. Push down the SET/COAST switch w hen the system detects a vehicle ahead.
4. Check that the vehicle-to-vehicle distance control mode is performed so that the vehicle maintains a
proper distance according to the vehicle speed [maximum: approximately 32 km/h (20 MPH)] when
releasing SET/COAST switch.
NOTE:
The vehicle-to-vehicle distance control mode cannot be set when the vehicle speed is less than 32 km/h (20
MPH) and when a vehicle ahead is not detected.
Cancel the control automatically w hen the vehicle speed is 24 km/h (15 MP H) or less during the control and
when the system does not detect any vehicle ahead.
The set vehicle speed indicator in the ICC system display on the information display is set to 32 km/h (20 MPH).
>> GO TO 8.
8.CHECK FOR INCREASE OF CRUISING SPEED (2)
1. Set the vehicle-to-vehicle distance control mode when the vehicle speed is less than approximately 32
km/h (20 MPH) and when a vehicle ahead is detected.
2. Check that 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-vehicl e distance control mode is 144 km/h (90 MPH).
CAUTION:
Never set the cruise speed exceed ing the posted speed limit.
>> GO TO 9.
9.CHECK FOR DECREASE OF CRUISING SPEED INSPECTION (2)
1. Set the vehicle-to-vehicle distance control mode when the vehicle speed is less than approximately 32
km/h (20 MPH) and when a vehicle ahead is detected.
2. Set the set vehicle speed to the desired vehicle speed according to “check for increase of cruising speed”.
3. Check that the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:
The minimum the set speed is approximately 32 km/h (20 MPH).
If the vehicle ahead comes to a stop, the vehicle decelerat es to a standstill within the limitations of the sys-
tem. The system will cancel once it j udges a standstill with a warning chime.
CAUTION:
The creep occurs because the stop status is not maintained.
>> GO TO 10.
10.CHECK FOR CANCELLATION OF VEHICLE-T O-VEHICLE DISTANCE CONTROL MODE
Check that the vehicle-to-vehicle distance control m ode is canceled when performing the following operations.
When the brake pedal is depressed after vehicle-to-vehi cle distance control mode is set and the vehicle is
driven.
When the selector lever is in the “N” position after vehicle-to-vehicle distance control mode is set and the
vehicle is driven.
When the MAIN switch is turned OFF after vehicle-to -vehicle distance control mode is set and the vehicle is
driven.
When the CANCEL switch is pressed after vehicle-to-v ehicle distance control mode is set and the vehicle is
driven.
>> GO TO 11.
