7. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Misalignment Reading.
8. Check and make a note of the amount of misalignment.
9. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Offset Reading.
10. Check and make a note of the amount of misalignment.
11. Calculate the Dealership Axis Offset Angle (with On-line Calibration Angle) using the values of Front Beam Axis Misalignment Reading and Front Beam Axis Offset Reading.
