1. Attach the ruler (2) at 14 mm (0.55 in) (H) below the center (A) of\
the ICC target board (1).
2. Adjust the ICC target board height to the position aligning the ruler (1) upper side tip with the center of laser beam axis (A).
NOTE:
The center of laser beam axis (A) is located at 38 mm (1.5 in) (W)
from the left end of ICC sensor and 22 mm (H) (0.87 in) from above
when viewed from the front of the vehicle.
To identify the laser beam axis center (A) easily, prepare a piece of paper (B) cut to the size of 38 mm (1.5 in) (W) × 22 mm (0.87 in)
(H) and attach it on the lower left point of the ICC sensor (1).

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.

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.

DescriptionINFOID:0000000006224453
The detection function may become unstable in the following cases.
When the reflector of the vehicle ahead is def icient/ not clean enough to reflect ICC sensor.
When driving a road with extremely sharp corners.
When the sensor cannot detect the reflector of the vehicle ahead as the vehicle ahead is passing a hill or
passing the peak.

Description".
3. Check that the vehicle ahead detection performance improves.
Does it improve?
YES >> INSPECTION END
NO >> GO TO 5.
5.REPLACE ICC SENSOR
1. Replace ICC sensor. Refer to CCS-176, "
Exploded View".
2. Adjust the laser beam aiming. Refer to CCS-72, "
Description".

Description".
4. Check that the vehicle ahead detection performance improves.
Does it improve?
YES >> INSPECTION END
NO >> GO TO 6.
6.REPLACE ADAS CONTROL UNIT
Replace ADAS control unit. Refer to DAS-63, "
Removal and Installation".
>> GO TO 7.
7.CHECK ICC SYSTEM

Monitored item
[Unit] Description
VHCL SPEED SE
[km/h] or [mph] Vehicle speed judged from a vehicle speed signal read by the ICC sensor via ITS communica-
tion is displayed [ADAS control unit receives a vehicle speed signal from ABS actuator and
electric unit (control unit) via CAN communication and transmits the calculated vehicle speed
to ICC sensor via ITS communication]
YAW R AT E
[deg/s] Indicates yaw rate read from ADAS control unit through ITS communication (ADAS control unit
receives yaw rate signal from ABS actuator and electric unit (control unit) via CAN communi-
cation and transmits yaw rate calculated by the ADAS control unit)
Yaw rate judged from a yaw rate signal read by ICC sensor via ITS communication is displayed
[ADAS control unit receives a yaw
rate signal from ABS actuator and electric unit (control unit)
via CAN communication and transmits the calculated yaw rate to ICC sensor via ITS commu-
nication]
