LASER BEAM AIMING ADJUSTMENT
Revision: 2006 January2006 M35/M45
2. Adjust the height of the target board with aligning the upside tip
of the triangle scale with the center of laser beam axis.
NOTE:
The center of laser beam axis is located at 92 mm (3.62 in) from
the right edge and 22 mm (0.87 in) from the top of the ICC sen-
sor integrated unit from a front view of vehicle.
ADJUSTING THE RIGHT-LEFT POSITION OF THE TARGET
1. Attach a scale [at least 350 mm (14 in) or longer] or stick as
shown in the figure.
2. Suspend a thread with weight on the tip of the thread to 266 mm
(10.47 in) right side of the target board from the center of the
target board on top.
SETTING THE TARGET
1. Suspend a thread with weight on tip to splice the center of the front and rear bumpers. Then, mark the
center point on the ground as each weight points.
2. Link the front and rear bumpers center points marked on the ground, and mark a point 3.9 m (12.8 ft)
ahead of the front bumper, on the extended line of the previous link line of the bumper center points.
Then, adjust the position of the target board so that the weight come on the top of the marked point [3.9 m
(12.8 ft) ahead of the front bumper] and face to the vehicle.

3. Adjust the position of the target board so that the extended line
that links the center of the rear window glass (the center of the
rear window defogger pattern) and the center of the windshield
(the setting part of the room mirror) align with the weight sus-
pended from the board.
4. Remove the thread suspended to the right side of board and
suspend a thread with weight on tip on the center of the target
board. Then mark the point of weight on the ground.
5. Pivot the edge of the target board 25
to either side.
NOTE:
Approx. 90 mm (3.54 in) shift rates the 25
movement.
NOTE:
The distance between center of laser beam axis and target board is 4 m (13 ft).
6. Do not place anything in the space shown in the figure (view from top).
NOTE:
In case the space shown in the figure is not available, make a space by covering the side of the target
board with a 1400 mm (4.6 ft)-size frosted black board or black cloth.
