Special Repair Requirement (Laser Beam Aiming Adjustment)

INSPECTION AND ADJUSTMENT


LASER BEAM AIMING ADJUSTMENT : Special Repair Requirement (Laser Beam Aiming Adjustment)


DESCRIPTION
- Adjust the laser beam aiming in a vertical direction with CONSULT-III as per the following.
- The laser beam aiming adjustment in a horizontal direction is performed automatically with CONSULT-III.

CAUTION:
- Never look directly into the laser beam source (ICC sensor integrated unit body window) during laser beam aiming adjustment.
- Perform all necessary work for laser beam aiming adjustment until the adjustment completes as shown in the procedure. If the procedure does not complete, the ICC system is inoperable.
1.SET CONSULT-III TO THE LASER BEAM AIMING ADJUSTMENT MODE
1. Start the engine.
2. Connect CONSULT-III and select "Work support" of "ICC".
3. Select "LASER BEAM ADJUST" after the "Work support" screen is displayed.
4. Select "START" after the "LASER BEAM ADJUST" screen is displayed.

NOTE:
If the adjustment screen does not appear within approximately 10 seconds after "LASER BEAM ADJUST" is selected, the following causes are possible.
- The ICC target board is not installed in the correct position.
- Adequate space is not secured around the ICC target board.
- The laser beam aiming adjustment exceeds its proper installation range.
- Deformation of vehicle body.
- Deformation of unit.
- Deformation of bracket.
- The area is not suitable for the adjustment work.
- ICC sensor integrated unit body window is not clean.
- The ICC system warning lamp illuminates.
- GO TO 2.
2.LASER BEAM AIMING ADJUSTMENT
After "ADJUST THE VERTICAL OF LASER BEAM AIMING" is displayed on CONSULT-III screen, adjust by turning the up-down direction adjusting screw until "U/D CORRECT" becomes �4 or less.

NOTE:
- Turn the up-down direction adjusting 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 up-down direction adjusting screw is turned half a rotation.





- Turning the up-down direction adjusting screw (A) clockwise directs the laser beam downward (B). The laser beam directs upward (C) when turning up-down direction adjusting screw counterclockwise.

CAUTION:
Be careful not to cover the ICC sensor integrated unit body window with a hand or the other part of body of worker during adjustment.
- GO TO 3.
3.LASER BEAM AIMING CONFIRMATION
1. When the "U/D CORRECT" value becomes �4 or less, check that no value greater than �4 appears when the vehicle is left with no load on the ICC sensor integrated unit (hand removed) for at least 2 seconds.
2. When "COMPLETED THE VERTICAL AIMING OF LASER BEAM" display appears, touch "END".

CAUTION:
Always check that the value of "U/D CORRECT" remains �4 or less when the ICC sensor integrated unit is left alone for at least 2 seconds.
3. Check that "ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING" is displayed and wait for a short period of time. (The maximum: Approx 10 seconds).
4. Check that "Normally Completed" is displayed, and select "End" to end "LASER BEAM ADJUST".

CAUTION:
Once "LASER BEAM ADJUST" is started with CONSULT-III, always continue the work until the horizontal laser beam aiming adjustment is completed successfully. If the job is stopped midway, the laser beam aiming is not adjusted and the ICC system cannot operate.
