LASER BEAM AIMING ADJUSTMENT

LASER BEAM AIMING ADJUSTMENT: Outline of Laser Beam Aiming Adjustment Procedure

CAUTION:
- The laser beam aiming adjustment cannot be performed without CONSULT-III.
- 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. For details, refer to Technical Service Bulletin.

Tool number: KV99110100 (J-45718)

3. Adjust the sensor following the procedure on CONSULT-III.
4. Check system operation after the adjustment.

LASER BEAM AIMING ADJUSTMENT: Preparation
- 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 SCS-7, "CONSULT-III Function".




- Clean the sensor with a soft cloth.

LASER BEAM AIMING ADJUSTMENT: Setting up the ICC Target Board

CAUTION: Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment. For details, refer to Technical Service Bulletin.

ADJUSTING HEIGHT OF THE TARGET




1. Attach a triangle scale as shown.




2. Adjust the height of the target stand so that the point of the triangle 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 center points 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 center point 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 colored, place a 400 mm (15.75 in) long frosted black board or black cloth to both sides of the target board.
