MATRIX LED HEADLAMP, CALIBRATING, USING Headlamp Adjusting Unit : VAS5209B
Special tools and workshop equipment required
- Headlamp Adjusting Unit: VAS5209B
The Matrix LED headlamp is calibrated using the Vehicle Diagnostic Tester.
In this procedure the low beam is set first. Then the Matrix beam high beam function is calibrated.
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)
- The headlamp was adjusted.
- The Drivetrain Control Module -J775- was calibrated or replaced.
- One of the level control system sensors was replaced.
- The Headlamp Range Control Module -J431- was replaced.
- In the DTC memory an entry is present, which indicates an incorrect calibration of the Matrix headlamps.
- Left Matrix Headlamp Power Output Module -A44-, Right Matrix Headlamp Power Output Module -A45- was replaced.
Requirements
- Pay attention to the testing and adjustment requirements. Refer to HEADLAMP, ADJUSTING, GENERAL INFORMATION .
Avoid having ambient lighting too high or shaking.
If the ambient lighting is too high or is shaking, this can lead to incorrect measurements on the Headlamp Adjusting Unit: VAS 5209B .
Procedure
-- Align the : VAS5209B at the distance -a- = 100 mm to the vehicle center. Refer to the : VAS5209B Owner's Manual.
-- Check the parallel alignment of the : VAS5209B to the vehicle transverse axis. To do so, align the laser beam of the : VAS5209B to the left and right front fender bolts -arrows-.
-- Push the : VAS5209B in front of the left headlamp and check the parallel alignment again.
- To prevent a glare for other motorists, pay attention to the exact orientation of the headlamp adjusting unit.
Calibrating
The Vehicle Diagnostic Tester is connected.
-- Select the Diagnostic mode and start the diagnostic.
-- Select the Test plan tab.
-- Press the Select individual tests button and select the following one after the other:
- Body
- Electrical Equipment
- 01 - OBD-capable systems
- 55 - Headlamp Range Control Module (MxB) - J431
- 55 - Headlamp range control, functions
- 55 - Matrix beam basic setting
From here, the Vehicle Diagnostic Tester advances the calibration procedure forward. The low beam must be adjusted first for this procedure. Refer to HEADLAMP, ADJUSTING, LED HEADLAMP .
Further along in the program sequence a request is made to determine/read and to input the angle value of the inner segment edge of the left headlamp in the headlamp adjusting unit.
-- Center the light collecting box lens to the headlamp reference segment.
-- In the main menu of the : VAS5209B press the "F1" button -arrow- to measure the angle value.
Shown on display:
-- Push the button -arrow- for the left fog lamp for at least three seconds.
Shown on display:
- The angle values of the inner reference segment edge are displayed.
-- Enter the angle value -arrow- of the inner reference segment edge in the Vehicle Diagnostic Tester. While doing so, pay attention to the sign if necessary.
-- Push the "F4" button -arrow- on the : VAS5209B .
Further along in the program sequence a request is made to determine/read and to input the angle value of the inner segment edge of the right headlamp in the headlamp adjusting unit.
-- Align the : VAS5209B at the distance -a- = 100 mm to the center of the vehicle. Refer to the : VAS5209B Owner's Manual.
-- Check the parallel alignment of the : VAS5209B to the vehicle transverse axis. To do so, align the laser beam of the : VAS5209B to the left and right front fender bolts -arrows-.
-- Push the Headlamp Adjusting Unit: VAS5209B in front of the right headlamp and check the parallel alignment again.
-- Center the light collecting box lens to the headlamp reference segment.
-- In the main menu of the : VAS5209B , press the "F1" button -arrow- to measure the angle value.
Shown on display:
-- Push the button -arrow- for the right fog lamp for at least three seconds.
Shown on display:
- The angle values of the inner reference segment edge are displayed.
-- Enter the angle value -arrow- of the inner reference segment edge in the Vehicle Diagnostic Tester. While doing so, pay attention to the sign if necessary.
-- Push the "F4" button -arrow- on the : VAS5209B .
-- After completing the calibration, read the DTC memory and correct any existing faults.
