LASER BEAM AIMING ADJUSTMENTPFP:00026
Outline of Laser Beam Aiming Adjustment ProcedureEKS00BLN
CAUTION:

The laser beam aiming adjustment cannot be performed without CONSULT-II.

The laser beam aiming adjustment must be performed every time the ICC sensor is removed,
installed or has been moved as a result of a collision.
1. Prepare the vehicle and the work area.
2. Set up the ICC target board.
3. Adjust the sensor following the procedure on CONSULT-II.
4. Check system operation after the adjustment.
PreparationEKS00BLO

Place the vehicle on level ground. Shift the transmission into "P" position and release the parking brake.

Adjust the tire pressure to the specified value.

See that there is no load in the vehicle. Coolant, engine oil and fuel should be filled to correct level.

Check that the vehicle suspension has been adjusted to the standard height by the load leveling rear air
suspension system. Refer to RSU-12, "
Basic Inspection" .

Clean the sensor with a soft cloth.
Setting up the ICC Target BoardEKS00BLP
CAUTION:
Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown.Tool number : KV99110100 (J-45718)

2. Adjust the height of the target stand so that the point of the trian-
gle aims above the center of the ICC sensor.
ADJUSTING THE POSITION OF THE TARGET BOARD STRING
1. Attach a scale or straightedge (at least 350 mm [14 in] or
longer).
2. Suspend a string with a weight on the end 218 mm
(8.6 in) to the left side of the target board center.
POSITIONING THE TARGET
1. Suspend a string with weights on each end over the centerline of the vehicle. The string should lay over
the center of the front and back bumpers. Mark these centerpoints on the ground at each weight.
2. Connect the two center points using a string. Extend the string
an additional 5 m (16 ft) beyond the front centerpoint and mark
the floor. Position the target board weight on this mark.
3. Relocate the suspended string from the left side of the target board to the center of the target board. Mark
this point on the ground.

4. Pivot the target board on its center mark 20° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift will produce a 20° movement.
5. Remove any items in the shaded space shown in the figure.
NOTE:
In case the background space shown in the illustration is not available, or if the background is light col-
ored, place a 400 mm (15.75 in) long frosted black board or black cloth to both sides of the target board.
Sensor AdjustmentEKS00BLQ
CAUTION:

Complete all necessary steps for laser beam adjustment until the the CONSULT-II indicates "COM-
PLETED". If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used without connection to the CONSULT-II CONVERTER, malfunctions might be
detected during self-diagnosis.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.

3. Start the engine, wait for at least 10 sec., and touch “START
(NISSAN BASED VHCL)”.
4. Touch “ICC”.
If “ICC” is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
5. Touch “WORK SUPPORT”.
6. Touch “LASER BEAM ADJUST”.
7. Touch “START”.
CAUTION:
If the adjustment screen does not appear on CONSULT-II 10
sec. after touching “LASER BEAM ADJUST” screen, the fol-
lowing causes may be considered:

Target is not set accurately.

There is not enough space beside the target.

Deformation of vehicle or inappropriate installation of
sensor. Sensor may be installed out of the adjustable
range.

The area is not suitable for the adjustment work.

ICC sensor is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the vertical adjusting screw until
“U/D CORRECT” value is set in the range of ±4.
CAUTION:
Turn the screw slowly. The value on the CONSULT-II is
slower than the actual movement of the ICC sensor. Wait 2
seconds between each adjustment. Also, during adjust-
ment work, do not block the ICC sensor lens with your hand
or body. In that case, there are times when aiming cannot
be conducted correctly.
NOTE:
Turning the screw clockwise raises the ICC sensor and counter-
clockwise lowers the ICC sensor.
9. When “U/D CORRECT” value indicates ±4, confirm that the value remains within ±4 for at least 2 seconds
while nothing is touching the ICC sensor.
When “COMPLETED THE VERTICAL AIMING OF LASER
BEAM” appears on screen, touch “END”.
CAUTION:
Be sure that the margin of “U/D CORRECT” is within ±4
when the ICC sensor unit is untouched.
10. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER
BEAM AIMING” is on screen and wait while the horizontal
adjustment is made automatically. (maximum: 10 seconds).

11. Confirm that “NORMALLY COMPLETED” is displayed on CON-
SULT-II and close the aiming adjustment procedure by touching
“END”.
CAUTION:
Complete all the procedures once “LASER BEAM ADJUST”
mode is entered in CONSULT-II. When the procedure is dis-
continued, the ICC system is inoperable.
CHECK AFTER THE ADJUSTMENT
Test the ICC system by performing the ICC System Running Test. Refer to ACS-9, "ICC System Running Test"
.
