Distance Sensor: Adjustments
LASER BEAM AIMING ADJUSTMENTOutline
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).
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 with a soft cloth.
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 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 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 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 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 5 m (16.4ft) 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 (16.4ft) 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 suspended 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.
5. Pivot the edge of the target board 20 ° to either side.
NOTE: Approx. 50 mm (1.97 in) shift rates the 20 ° movement.
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 space by covering the side of the target board with a 400 mm (15.75 in)-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 on the data link connector.
3. Start the engine, wait for at least 10 seconds, and touch "START (NISSAN BASED VHCL)".
4. Touch "ICC".
If "ICC" is not indicated, go to GI-40, "CONSULT-II Data Link Connector (DLC) Circuit". Data Link Connector 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.
- Deformation of vehicle or the surrounding equipment unit, bracket, or the surrounding equipment is causing inappropriate installation of sensor and aiming may be set 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 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. Wait for 2 seconds every time the screw is turned half a rotation.
NOTE: Turning the screw to the right lowers the aiming and to the left lifts the aiming.
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.
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 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 running test. Refer to "ICC System Running Test".
