📋 Procedure

1. Select calibration procedure for front camera in wheel alignment computer.
2. Attach quick-release clamps to all four wheels.
3. Attach rear wheel alignment sensors.
4. Carry out wheel rim runout compensation for rear wheels.

9. Close all vehicle doors.
10. Measure height of body (a) at all four wheels between tyre contact surface and bottom edge of wing panel/wheel housing at centre of wheel. Note down measurement.
11. Select calibration procedure for front camera in wheel alignment computer.
12. Check that calibration screen is positioned centrally and engaged properly.
13. Set up VAS 6430 as shown in illustration so that distance (A) measured from hub centres of front wheels to cross bar of VAS 6430 is 150 cm ± 2.5 cm. [Note: Do not take hold of the cross bar when moving the VAS 6430.]
14. Attach front wheel alignment sensors (1) to VAS 6430. [Note: For the next step the wheel alignment platform must be set at the lowest available position.]
15. Determine height difference (A) between floor level where VAS 6430 is set up and tyre contact surface as shown in illustration and enter this value in the wheel alignment computer.
16. Loosen bolt (arrow) and set measuring bar (1) on floor.
17. Using crank (1), adjust calibration screen to specified height (2) as indicated by wheel alignment computer. [Note: If the height of the calibration screen has to be corrected at a later stage of the procedure, the measuring bar must be set on the floor when making the adjustment.]
18. Set spirit level (A) to horizontal position with adjuster screw (1).
19. Move VAS 6430 sideways (arrow B) until display on wheel alignment computer is within tolerance.
20. Secure by tightening bolts (2) and (3)VAS 6430 lightly. (This will prevent the VAS 6430 from rolling away).
21. Turn fine adjustment screw (1) until display on wheel alignment computer is within tolerance.
22. Set spirit level (A) to horizontal position with adjuster screw (1).
23. Set spirit level (B) to horizontal position with adjuster screw (2).
24. Select Guided Fault Finding mode.
25. Press the Go to button, select the option "“Function/component selection”" and then select the following menu items:
26. Select Diagnosis mode and start the diagnosis.
27. Select Test plan tab.
