LASER BEAM AIMING ADJUSTMENT
Revision: 2004 November 2004 FX35/FX45
LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineAKS006YI
Adjust the laser beam aiming every time the ICC sensor is removed or installed.
CAUTION:

Place the vehicle on the level ground when the laser beam aiming adjustment is operated.

Follow the CONSULT-II when adjusting the Laser beam aiming (Laser beam aiming adjustment
cannot be operated without CONSULT-II).
PreparationAKS006YJ

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.

See that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant, engine oil filled up to correct level and full fuel tank.

Shift the gear into “P” position and release the parking brake.

Clean the sensor with a soft cloth.
Outline of Adjustment ProcedureAKS006YK
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II (Turn manually the screw for up-down position
adjustment. ICC sensor automatically adjust the right-left position.).
Setting the ICC Target BoardAKS006YL
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.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown in the right figure.

2. Adjust the height of the target stand so that the point of the trian-
gle aims the center of the ICC sensor.
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 310 mm
(12.2 in) left side of the target board from the center of the tar-
get board on top.
SETTING THE TARGET
1. Suspend a thread with weight on tip to splice the center of the front and back bumpers. Then, mark the
center point on the ground as each weight points.
2. Link the front and back bumpers center points marked on the ground, and mark a point 5 m ahead of the
sensor, 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 (5 m ahead of the sensor) 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 (the center of the rear
window defogger pattern) and the center of the front windshield
(the setting part of the room mirror) align with the weight sus-
pended from the board.
4. Remove the thread suspended to the left 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.
