LASER BEAM AIMING ADJUSTMENT

Description

INFOID: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 ADJUST” on “Work support”) with CONSULT-III, and
then perform the adjustment according to the display. (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 seconds 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 source (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” position, and release the parking brake. 

4.

Fully fill the fuel tank, and then check that the 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 that 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)

LASER BEAM AIMING ADJUSTMENT

Suspend a weight from a string (1) attached to its end at the point (B)
leftward from the ICC target board center (A). 

>> GO TO 3.

3.

SETTING 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 point.

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 comes 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.

Remove the thread suspended to the left side of ICC target board and suspend a thread with weight on tip
on the center of the ICC target board. Then mark the point of weight on the ground.

4.

Pivot the edge of the ICC target board 25

°

 (a) to either side.

NOTE:
Approx. 90 mm (3.54 in) (b) shift rates the 25

 (a) movement.

>> GO TO 4.

4.

CHECK THE ICC TARGET BOARD INSTALLATION POSITION

Check that the ICC target board (1) is located as shown in the figure. 

NOTE:
The distance between laser beam axis and ICC target board is 4.0 m (13.0 ft).
