1. Adjust the reflector height.

   Refer to ADJUSTMENT [08/2019 - ]

2. Place the reflector.

   Refer to ADJUSTMENT [08/2019 - ]

3. Connect the Techstream to the DLC3.
4. Turn the engine switch on (IG).
5. Turn the Techstream on.
6. Turn the cruise control main switch on.
7. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Misalignment Reading.
8. Check the amount of misalignment and make a note.
9. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Offset Reading.
10. Check the amount of misalignment and make a note.
11. Calculate the "Dealership Axis Offset Angle (with On-line Calibration Angle)" using the values "Front Beam Axis Misalignment Reading" and "Front Beam Axis Offset Reading".
    1. "Dealership Axis Offset Angle (with On-line Calibration Angle)" = "Front Beam Axis Misalignment Reading" - "Front Beam Axis Offset Reading"

       Standard

       Dealership Axis Offset Angle (with On-line Calibration Angle) 

       Vertical	-2.2 to 1.6 deg.
       Horizontal	-0.6 to 0.6 deg.
