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.

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.

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).

CAUTION:
 Perform this operation in a horizo ntal position where there is a clear view for 5 m (16.4 ft) forward
and 3 m (9.84 ft) wide.
 Place the target in a well-lig hted location. (Poor lighting may make it hard to adjust.)
 The target may not be detected when there is a ligh t source within 1.5 m (4.92 ft) from either side and
within 1 m (3.28 ft) upward/downward from the target.
 Check the location of the sun. (S unlight should not shine directly on the front of the vehicle.)
 The target may not be detected when there is the same pattern of black and white as the target when
the pattern is within 1 m (3.28 ft) from either si de and upward/downward position from the target. (It
is desirable that the vehicle is positioned on the opposite side of a single-color wall.)
1.TARGET SETTING
1. Mark points “A”, “B”, “C” and “D”at the center of the lateral sur- face of each wheels.
NOTE:
Hang a string with a cone from the fender so as to pass through
the center of wheel, and then mark a point at the center of the
lateral surface of the wheel.
2. Draw line “LH” passing through points “A” and “B” on the left side
of vehicle.
NOTE:
Approximately 4 m (13.12 ft) or mo re from the front end of vehi-
cle.
