Distance Sensor: Adjustments
LASER BEAM AIMING ADJUSTMENTOutline
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 cannot be operated without CONSULT-II).
- Never ride on vehicle during laser beam aiming adjustment.
- Idle and turn headlamps OFF during laser beam aiming adjustment.
Preparation
- 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.
Outline of Adjustment Procedure
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 Board
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.
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 sensor 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 suspended 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.
Aiming Adjustment
CAUTION:
- Complete all necessary work for laser beam adjustment until the adjustment completes as shown in the procedure. If the procedure does not complete, the ICC system is inoperable.
- If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.
3. Start engine, wait for at least 10 seconds, and touch "START (NISSAN BASED VHCL)".
4. Touch "ICC".
If "ICC" is not indicated, go to GI-41, "CONSULT-II Data Link Connector (DLC) Circuit". Schematic
5. Touch "WORK SUPPORT".
6. Touch "LASER BEAM ADJUST".
7. Touch "START".
CAUTION: If the adjustment screen does not appear on the CONSULT-II screen in 10 seconds. After touching "LASER BEAM ADJUST" screen, the following causes may be considered:
- Target is not set accurately.
- There is not enough space beside the target.
- The range of laser beam aiming exceeds for improper installation position.
- Deformation of vehicle body.
- Deformation of unit.
- Deformation of bracket.
- The area is not suitable for the adjustment work.
- ICC sensor integrated unit is not clean.
8. After the CONSULT-II displays "ADJUST THE VERTICAL OF LASER BEAM AIMING" turn the up-down direction adjusting screw until "U/D CORRECT" value is set in the range of ?4.
CAUTION: Turn the screw slowly. The value change on display is slower than actual movement of the ICC sensor integrated unit. Wait for 2 seconds every time the screw is turned half a rotation.
NOTE: Turning the screw clockwise to laser beam is downward and counterclockwise to laser beam is upward.
9. When "U/D CORRECT" value indicates ±4, confirm that the margin of value remains within ?4 at least for 2 seconds with no equipment or hand touching the ICC sensor integrated unit.
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 with ICC sensor integrated unit is untouched.
10. Confirm that "ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING" is on screen and wait for a while (maximum: 10 seconds).
11. Confirm that "NORMALLY COMPLETED" is displayed on CONSULT-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 discontinued, the ICC system is inoperable.
CHECK AFTER THE ADJUSTMENT
Test the ICC system operation by ICC system running test. Refer to "ICC System Running Test". Action Test
