>> GO TO 2.
2.SELF-DIAGNOSIS WITH CONSULT-III
1. Perform “All DTC Reading” with CONSULT-III.
2. Check if any DTC is detected in self-d iagnosis results of “ICC/ADAS” and “LASER”.
Is any DTC detected?
YES >> GO TO 5.
NO >> GO TO 3.
3.ACTION TEST
Perform the ICC system action test to check the operation status. Refer to CCS-77, "
Description".
Check if any other malfunctions occur.
>> GO TO 4.
4.SYMPTOM DIAGNOSIS
Perform the applicable diagnosis according to the diagnosis chart by symptom. Refer to CCS-160, "
Symptom
Table".
>> GO TO 6.
5.TROUBLE DIAGNOSIS BY DTC
1. Check the DTC in the self-diagnosis results.
2. Perform trouble diagnosis for the detected DTC. Refer to CCS-50, "
DTC Index" (ICC/ADAS) or CCS-55,
"DTC Index" (LASER).
NOTE:
If “DTC: U1000” is detected, first diagnose the CA N communication system or ITS communication system.
>> GO TO 6.
6.MALFUNCTIONING PART REPAIR
Repair or replace the identified malfunctioning parts.
>> GO TO 7.
7.REPAIR CHECK (SELF-DIAG NOSIS WITH CONSULT-III)
1. Erases self-diagnosis results.
2. Perform “All DTC Reading” again after repairing or replacing the malfunctioning parts.
3. Check if any DTC is detected in self-d iagnosis results of “ICC/ADAS” and “LASER”.
Is any DTC detected?
YES >> GO TO 5.
NO >> GO TO 8.
8.REPAIR CHECK (ACTION TEST)
Perform the ICC system action test. Check if the malfunction symptom is solved or no other symptoms occur.
Is there any malfunction symptom?
YES >> GO TO 4.
NO >> INSPECTION END

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.

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.

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).
