Preliminary Work

Information 

Set vehicles with air suspension to normal level (medium height). 

1. Perform initial chassis measurement and adjust the chassis if necessary.

   > 449503 PERFORMING FRONT + REAR SUSPENSION ALIGNMENT

2. > VAS 6430/1A - Setting device with reflector  with > VAS 6430/6 - Enhanced night vision calibration unit  must be set up and aligned parallel with the front of the vehicle in accordance with the operating instructions for VAS 6430.
3. For distance -A -  from setting device to vehicle, see PIWIS Tester.

5. VAS 6350/3A Linear laser (contained in > VAS 6350A - calibration unit  set) must be fitted on > VAS 6430/6 - Enhanced night vision calibration unit. VAS 6350/3A Linear  laser must now be switched on. A laser beam is projected onto the front of the vehicle. > VAS 6430/1A - Setting device with reflector  must be aligned by turning the crank on the back so that the laser beam hits the centre of the camera lens of the night vision camera in its horizontal position.
6. > VAS 6430/6 - Enhanced night vision calibration unit  must be switched on and pre-heated.

   If calibration is cancelled because the calibration plate is too cold, the fault memory must be cleared before trying to perform calibration again.
