LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS004CM
Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
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-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).

Never ride on vehicle during laser beam aiming adjustment.

Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS004CN

Adjust the tire pressure to the specified value.

See that there is no load in the vehicle.

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 ICC sensor integrated unit with a soft cloth.

Remove the front bumper grille. Refer to EI-13, "Removal and
Installation of Front Bumper Grille" .
Outline of Adjustment ProcedureNKS004CO
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 integrated unit automatically adjust the right-left position.)
Setting the ICC Target BoardNKS004CP
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 at 28 mm (1.10 in) below the center.

LASER BEAM AIMING ADJUSTMENT
Revision: 2007 April2007 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.

HOOD
Revision: 2007 April2007 M35/M45
1. Check the clearance and the surface height between the hood and each part by visual and tactile feeling.
(Fitting standard dimension in the table below should be satisfied.)
* Unit: mm (in)
2. In case out of specification, adjust them according to the procedures shown below.
3. Remove the hood lock and adjust the height by rotating the
bumper rubber until the hood becomes 1 to1.5 mm (0.04 to
0.059 in) lower than the fender.
4. Temporarily tighten the hood lock, and position by engaging it with the hood striker. Check the lock and
striker for looseness and adjust the clearance and evenness by the striker to satisfy the specification.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or the hood pressed lightly (approx. 29 N (3 kg)).
6. After adjustment tighten lock bolts to the specified torque.
