LASER BEAM AIMING ADJUSTMENT
LASER BEAM AIMING ADJUSTMENT
DescriptionINFOID:0000000006224293
OUTLINE OF LASER BEAM AIMING ADJUSTMENT
Always adjust the laser beam aiming after removing and installing or replacing the ICC sensor.
CAUTION:
The system does not operate normally
unless the laser beam aiming adjustment is performed. Always
perform it.
1. Set the ICC target board [SST: KV99110100 (J-45718)] to the correct position in front of the vehicle.
2. Set the laser beam aiming mode (“LASER BEAM AD JUST” on “Work support”) with CONSULT-III, and
then perform the adjustment according to the displa y. (Manually turn the up-down direction adjusting
screw for vertical adjustment. ICC sensor adjusts the automatic aiming for the horizontal direction.)
CAUTIONARY POINT FOR LASER BEAM AIMING ADJUSTMENT
CAUTION:
 For laser beam aiming adjustment, choose a level location where a view can be obtained without any
obstruction as far as 12 m (39 ft) or more in the forward direction.
 Adjust laser beam aiming for 5 second s or more after starting engine.
 Adjust the laser beam aiming with CONSULT-III. (The laser beam aiming cannot be adjusted without
CONSULT-III.)
 Never enter the vehicle during laser beam aiming adjustment.
 Never look directly into the laser beam sour ce (ICC sensor body window) during laser beam aiming
adjustment.
 Laser beam aiming adjustment is performed at idle. At this time, turn the headlamps OFF.
Work Procedure (Preparation)INFOID:0000000006224294
1.ADVANCE PREPARATION FOR LASER BEAM AIMING ADJUSTMENT
1. Adjust all tire pressure to the specified value.
2. Empty the vehicle. (Remove any luggage from the passenger compartment, luggage room, etc.)
3. Shift the selector lever to “P” pos ition, and release the parking brake.
4. Fully fill the fuel tank, and then check that t he coolant and oils are filled up to correct level.
5. Clean off the ICC sensor body window with a soft cloth.
>> Go to CCS-72, "
Work Procedure (Setting The ICC Tar-
get Board)".
Work Procedure (Setting The ICC Target Board)INFOID:0000000006224295
DESCRIPTION
Accurate adjustment of the laser beam requires t hat the ICC target board be accurately positioned.
CAUTION:
If the laser beam is adjusted with the ICC target board in the incorrect position, the ICC system does
not function normally.

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.

ACTION TEST
DescriptionINFOID:0000000006224297
Always perform the ICC system action test to check that the ICC system operates normally after replacing the
ICC sensor or repairing any ICC system malfunction.
CAUTION:
 Always drive safely when pe rforming the action test.
 Turn the DCA system to OFF when performing the action test.
Work Procedure (Vehicle-To-Vehicle Distance Control Mode)INFOID:0000000006224298
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 running speed can be set between 32 km/h (20 MPH) and 144 km/h (90 MPH).
CAUTION:
Never set the cruise speed exceeding the posted speed limit.
1.CHECK FOR MAIN SWITCH
1. Start the engine.
2. Press the MAIN switch (1) (less than 1.5 seconds).
3. Check the ICC system display on the information displa y to check that the vehicle-to-vehicle distance con-
trol mode is ready for activation.
4. Press the MAIN switch, and check that the ICC syst em display on the information display turns OFF when
the ICC system is deactivated.
5. Check that the ICC system displa y on the information display turns OFF after starting the engine again.
>> GO TO 2.
2.CHECK FOR DISTANCE SWITCH
1. Start the engine.
2. Press the MAIN switch (less than 1.5 seconds).
3. Press the DISTANCE switch.

2. Press the MAIN switch (less than 1.5 seconds) and tu rn the vehicle-to-vehicle distance control mode ON.
3. Drive the vehicle at 32 km/h (20 MPH) or more.
4. Push down the SET/COAST switch.
5. Check that the desired speed is set and vehicle-to -vehicle distance control mode control starts when
releasing SET/COAST switch.
NOTE:
The set vehicle speed is indicated on the set vehicle s peed indicator in the ICC system display on the informa-
tion display.
>> GO TO 5.
5.CHECK FOR INCREASE OF CRUISING SPEED (1)
1. Set the vehicle-to-vehicle distance control mode at desired speed.
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.
