INFOID:0000000003130021

OUTLINE OF LASER BEAM AIMING ADJUSTMENT

Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
1.

Set up the ICC target board [SST: KV99110100 (J-45718)].

2.

Adjust the sensor following the procedure on CONSULT-III. (Turn manually the screw for up-down position
adjustment. ICC sensor integrated unit automatically adjust the right-left position.)

CAUTIONARY POINTS FOR LASER BEAM AIMING

CAUTION:

• Adjust laser beam aiming at a horizontal place as far as 12 m (39 ft) forward the vehicle can be seen.
• Adjust laser beam aiming 5 seconds after starting engine.
• Never view ICC sensor integrated unit body window directly during laser beam aiming adjustment.
• Follow the CONSULT-III when adjusting the laser beam aiming (laser beam aiming adjustment can-

not be operated without CONSULT-III).

• Never ride on vehicle during laser beam aiming adjustment.
• Idle and turn headlamps OFF during laser beam aiming adjustment.

LASER BEAM AIMING ADJUSTMENT : Special Repair Requirement (Setting The ICC 
Target Board)

INFOID:0000000003130023

Accurate ICC target board setting is required for the laser beam aiming adjustment.

CAUTION:

ICC system does not function normally if laser beam aiming is not accurate.

1.

ADJUSTING HEIGHT OF THE ICC TARGET BOARD

1.

Attach a ruler (2) at a position 42 mm (1.65 in) (H) below the
center (A) of the ICC target board (1). 

2.

Adjust the height of the ICC target board aligning the upside tip
of the ruler (1) 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 side and 22 mm (0.87 in) (H) from the top of the ICC
sensor integrated unit from a front view of vehicle.

INSPECTION AND ADJUSTMENT

• To identify the center of laser beam axis (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 upper left point of the ICC sensor inte-
grated unit (1). 

>> GO TO 2.

2.

ADJUSTING THE RIGHT-LEFT POSITION OF THE ICC TARGET BOARD

1.

Attach a ruler (1) or equivalent tool with a length of 450 mm
(17.72 in) or more to the back face of the ICC target board cen-
ter (A) in the leftward direction. 

2.

Suspend a thread with weight (1) at the point (B) rightward from
the ICC target board center (A). 

>> GO TO 3.

3.

SETTING THE ICC TARGET BOARD

1.

Suspend a thread with weight on tip from the center of the front and rear bumpers. Then, mark the center
points on the ground as each weight points.

2.

Link the front and rear bumpers center points marked on the ground and extend a straight line ahead.
Then mark a point 3.9 m (12.8 ft) position ahead of the front bumper. Then, adjust the position of the ICC
target board so that the weight come on the top of the marked point [3.9 m (12.8 ft) position ahead of the
front bumper] and face to the vehicle.

3.

Adjust the position of the ICC target board (1) so that the
extended line (A) that links the center of the rear window glass
(the center of the rear window defogger pattern) (B) and the cen-
ter of the windshield (the setting part of the room mirror) (C)
align with the weight suspended (2) from the ICC target board.
