Matrix LED Headlamp, Calibrating using Headlamp Adjusting Unit -VAS5209B-

Special tools and workshop equipment required

  • Headlamp Adjusting Unit -VAS5209B-

  Note

  • The Matrix LED headlamp is calibrated. Refer to Vehicle Diagnostic Tester.
  • In this procedure the low beam is set first. Then the Matrix beam high beam function is calibrated.

  Note

Software version from V 0.80 for the -VAS5209B- is required to calibrate the Matrix beam high beam function.

The Matrix Headlamp Must Be Calibrated after the following Work:

  • Headlamp position was changed (removing and installing, loosening and tightening the screws)
  • Headlamps were adjusted.
  • The Driver Assistance Systems Front Camera -R242- was replaced.
  • The Drivetrain Control Module -J775- was calibrated or replaced.
  • The Vehicle Electrical System Control Module -J519- was replaced.
