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.
>> Go to CCS-75, "
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.

LASER BEAM AIMING ADJUSTMENT
 Turn the up-down direction adjusting screw slowly. The value change on display is slower than actual move-
ment of the ICC sensor. Wait for 2 seconds every ti me the up-down direction adjusting screw is turned half a
rotation.
 Turning the up-down direction adjusting screw (A) clockwise (C)
directs the laser beam downward. The laser beam directs upward
when turning up-down direction adjusting screw counterclockwise
(B).
CAUTION:
Be careful not to cover the ICC sensor body window with a
hand or the other part of body of worker during adjustment.
>> GO TO 3.
3.LASER BEAM AIMING CONFIRMATION
1. When the “U/D CORRECT” value becomes ±4 or less, check that no value greater than ±4 appears when
the vehicle is left with no load on the ICC s ensor (hand removed) for at least 2 seconds.
2. When “COMPLETED THE VERTICAL AIMING OF LASER BEAM” display appears, touch “END”.
CAUTION:
Always check that the value of “U/D CORRECT” remains ±4 or less when the ICC sensor is left
alone for at least 2 seconds.
3. Check that “ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING” is displayed and wait for a
short period of time. (The maximum: Approx 10 seconds).
4. Check that “Normally Completed” is displayed, and select “End” to end “LASER BEAM ADJUST”.
CAUTION:
Once “LASER BEAM ADJUST” is started with CONS ULT-III, always continue the work until the
horizontal laser beam aiming ad justment is completed successfully. If the job is stopped midway,
the laser beam aiming is not adjust ed and the ICC system cannot operate.
