Led Headlamp, Adjusting, All Vehicles From My 2015
Special tools and workshop equipment required
- Headlamp Adjusting Unit for example Hopkines Vision 100 :AMA82005
Testing and Adjusting Conditions
- Tire pressure is OK.
- The headlamp glass must be clean and dry.
- The headlamp glass must not be damaged.
- Headlamp reflectors and bulbs are OK.
Vehicles with Steel Suspension:
- The vehicle must be under load.
Vehicle load on driver seat in otherwise unloaded vehicle (curb weight).
- One person or 75 kg (165 lbs).
The curb weight is the weight of the operational vehicle with a completely full fuel tank, including the weight of all equipment carried while in operation.
- Fuel tank: at least 90% full.
- Equipment: for example, spare tire, tools, vehicle jack, fire extinguisher, etc.
If the fuel tank is not at least 90% full, the load must be created as follows.
Use containers filled with water as additional weight (a five liter (1 pound) container filled with water weighs approximately 5 kg (11 lbs)).
-- Check the fuel tank fill level on the fuel gauge in the instrument cluster and compare it with the following table. Place additional weight in the luggage compartment, if necessary.
| Fuel Gauge | Additional Weight | ||
|---|---|---|---|
| 55 Liter (14.5 gallons) Fuel Tank | 65 Liter (17.1 Gallons) Fuel Tank | 75 liter (18.1 Gallons) Fuel Tank | |
| 1/4 | 42 kg (93 lbs) | 49 kg (108 lbs) | 57 kg (126 lbs) |
| 1/2 | 28 kg (62 lbs) | 33 kg (73 lbs) | 38 kg (84 lbs) |
| 3/4 | 14 kg (31 lbs) | 16 kg (35 lbs) | 19 kg (42 lbs) |
| full | 0 | 0 | 0 |
| Example: if the fuel tank is half full, an additional 38 kg (84 lbs) for example must be placed in the luggage compartment. | |||
Vehicles with Air Suspension:
- The pressure reservoir must be filled. Start the engine and let it run in the neutral for approximately two minutes.
Continuation for All Vehicles:
- The electro-mechanical parking brake must not be engaged so that the vehicle is not under stress.
- The vehicle and headlamp adjusting unit must be on a level surface.
- Headlamp adjusting unit must be aligned to the vehicle. To do this, slide the headlamp adjusting unit a distance of 100 mm centered in front of the vehicle and aligned to the vehicle front. Refer to Headlamp Adjusting Owner's Manual.
- Slide the headlamp adjusting unit in front of the corresponding headlamp and check the alignment again.
- LED and Matrix LED headlamp: The headlamp adjusting unit must be aligned at the center of the marked reflector segment -1-.
- The angle dimension is set on the headlamp adjusting unit. Refer to the Headlamp Adjusting Unit Operating Instructions.
- The angle dimension -arrow- is stamped for ECE countries on the upper edge of the headlamp -1- in "%".
- The standard angle dimension for the USA is 0.7%.
The percentage value is based on a 10 meter projection distance. An angle dimension of 1.0%, for example, converts to 10 cm.
Preliminary Work
-- Turn the light switch to "low beam" - not to "Auto".
-- Close all the doors and the rear lid and keep them closed for the duration of the testing/adjusting procedure.
-- Connect the Vehicle Diagnostic Tester.
The headlamps move into the basic setting with this program.
If the vehicle has air suspension, the suspension will move into the air suspension standard vehicle height at the same time.
-- Select the Diagnostic mode and start the diagnosis.
-- Select the Test plan tab.
-- Press the Select individual test button and select the following one after the other:
Vehicles without Matrix Beam
- Body
- Electrical Equipment
- 01 - OBD-capable systems
- 09 - Vehicle Electrical System Control Module J519
- 09 - Vehicle Electrical System Control Module, functions
- 09 - Headlamp basic setting (Rep.-Gr. 94)
Vehicles with Matrix Beam
- Body
- Electrical Equipment
- 01 - OBD-capable systems
- 55 - Headlamp Range Control Module (MxB) J431
- 55 - Headlamp Range Control, Functions
- 55 - Matrix beam basic setting (repair group 94)
-- Continue to follow the instructions in the Vehicle Diagnostic Tester display.
-- During the program, it will be asked to perform a headlamp adjustment.
Headlamp Adjustment
The image and the following description apply to analog headlamp adjusting units. Pay attention to the Owner's Manual for the digital headlamp adjusting units for example :AMA82005 . Refer to the Headlamp Adjusting Unit Owner's Manual.
- The horizontal cut-off line must touch the cut-off line -1- on the adjusting unit test surface.
- The bend point -2- between the left horizontal part and the right rising part of the cut-off line must run vertically through the central mark -3-. The bright core of the light beam must be to the right of the vertical.
To determine the bend point -2- more easily, cover and uncover the left half of the headlamp (seen in direction of travel) several times. Then check the low beam again.
After adjusting the low beam according to the instructions, the center of the high beam light beam must be on the central marking -3-.
-- Pry off cap (if applicable) off the adjusting bolt for adjusting the height.
-- To adjust the height of the headlamp, set the cut-off line above the dividing line with the adjusting bolt -2-.
-- Then adjust the cut-off line on the dividing line, starting from the top.
-- For side adjustment, turn adjusting bolt -1-.
The right headlamp layout is a mirror image.
If the program get interrupted, then the air suspension standard vehicle height must be deactivated manually. Refer to ELECTRONIC DAMPING .
-- After the headlamp adjustment has been successful, follow the instructions on the Vehicle Diagnostic Tester display in order to leave the air suspension standard vehicle height.
-- Disconnect the diagnostic connector.
