Special Repair Requirement (Setting the ICC Target Board)

INSPECTION AND ADJUSTMENT


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


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.ICC TARGET BOARD HEIGHT ADJUSTMENT





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

3 : Adjust nut
b : 90�





2. Adjust the ICC target board height to the position aligning the triangle scale (1) upper side tip with the center of laser beam axis
(A).

2 : ICC sensor integrated unit





- The center of laser beam axis (A) is located at 38 mm (1.5 in) (W) from the left end of ICC sensor integrated unit and 22 mm (H) (0.87 in) from above when viewed from the front of the vehicle.

B : Up-down direction adjusting screw





- 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) x 22 mm (0.87 in)
(H) and attach it on the upper left point of the ICC sensor integrated unit (1).
- GO TO 2.
2.ADJUSTING SIDE POSITION OF ICC TARGET BOARD





1. On the back of the ICC target board, attach the ruler (1) [450 mm (17.72 in) or more] or a similar tool squarely from the ICC target board center (A) in the left direction.





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

W [mm (in)] : 247 (9.72)

- 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 right 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.

1 : ICC target board
2 : String with a weight
C : ICC target board center marking point


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).
- GO TO 5.
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 available, cover the side of the ICC target board with a 1400 mm
(4.6 ft)-size frosted black board or black cloth.
