LASER BEAM AIMING ADJUSTMENT
Revision: 2006 July 2007 FX35/FX45
LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS003EQ
Adjust the laser beam aiming every time the ICC sensor 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-ll when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-ll).

Never ride on vehicle during laser beam aiming adjustment.

Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS003ER

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 with a soft cloth.
Outline of Adjustment ProcedureNKS003ES
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 BoardNKS003ET
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 the center.

2. Adjust the height of the target board stand so that the point of
the triangle 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 asshown 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 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 5 m (16.4 ft) 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 (16.4 ft) 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 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 left side of board and sus- pend a thread with weight on tip on the center of the target
board. Then mark the point of weight on the ground.

LONGITUDINAL AND LATERAL CLEARANCE ADJUSTMENT
1. Remove hood lock assembly, loosen the hood hinge nuts and close the hood.
2. Adjust the lateral and longitudinal clearance, and open the hood to tighten the hood hinge mounting bolts to the specified torque.
3. Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock become vertical viewed from the front, by moving the hood lock laterally.
4. Tighten hood lock mounting bolts to the specified torque.
CAUTION:
Adjust right/left clearance between hood and headlamp to the following specification.
FRONT END HEIGHT ADJUSTMENT
1. 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.
2. Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and striker for looseness, and tighten the hood lock mounting bolts to the specified torque.
SURFACE HEIGHT ADJUSTMENT
1. Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to the fitting standard dimension, by rotating RH and LH bumper rubbers.
2. Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver- tical when viewed from the front.

3. Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.
4. Make sure that the hood lock primary latch is securely engaged with the hood striker with hood's own weight by dropping hood
from approx. 200 mm (7.87 in) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
5. Move hood lockup and down until striker smoothly engages the lock when the hood is closed.
6. When pulling the hood opener lever gently, make sure that front end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch
is disengaged. Also make sure that hood opener returns to the original position.
7. After adjustment, tighten lock bolts to the specified torque.
CAUTION:
