4. 4
   After replacing the BCW unit or bracket with the bumper removed, use the BCW unit adjustment tool kit (Special Service Tool: 09985-3T500) to perform angle adjustment.
5. 5
   Attach the vertical plumb bob (Special Service Tool: 09958-3T010) to the hood and lower the plumb bob (A) to the ground so that it passes through the center of the emblem.

   

6. 6
   Mark the center point under the plumb bob (A).

   

7. 7
   Attach the vertical plumb bob (Special Service Tool: 09958-3T010) to the luggage compartment (or liftgate). and lower the plumb bob (A) to the ground so that it passes through the center of the emblem.

   

8. 8
   Mark the center point under the plumb bob (A).

   

9. 9
   Mark the vehicle centerline with a string.

   1. Run the string under the vehicle from the rear to the front and attach the string to the center point (A) at the front of the vehicle.
   2. Secure the string at point (C), approximately 1.5 – 2 m from the rear of the vehicle, so that it passes through the rear center point (B).

   

10. 10
    Install the BCW unit fixing adapter (Special Service Tool: 09958-3T080) on the BCW unit and mount the laser level (Special Service Tool: 09958-3T070).

    

11. 11
    Measure the angle (C) between the centerline (A) of the measuring angle plate and the horizontal laser beam (B) using the digital protractor (Special Service Tool: 09958-3T090).

    Horizontal Angle (C): 54° ± 3°

    

12. 12
    Use the digital inclinometer (Special Service Tool: 09958-3T100) to measure the vertical angle of the BCW unit.

    Vertical Angle: 87° (-0.75°/+1.25°)

    

13. 13
    Measure the horizontal and vertical angles of the left and right BCW units. If the measured values deviate from the specified values, insert a shim between the BCW unit bracket. Specifications: Horizontal Angle: 54° ± 3° Vertical Angle: 87° (-0.75°/+1.25°)

    

14. 14
    After inspecting and adjusting the BCW unit angle, perform the BCW Radar Calibration Procedure.
15. 15
    For vehicles with a rear bumper replaced in an accident, and vehicles where the BCW units have been replaced, perform BCW unit alignment using GDS.
16. 16
    Select the "BCW Radar Calibration" procedure in the BCW system.

    

17. 17
    Perform the "BCW Radar Calibration" procedure according to the GDS screen message.
