Service
Also see the Instruction Manual for the Hella Beamsetter Series IV for additional instructions and diagrams.
- Position vehicle on a flat floor surface that meets the following (ISO 10640) specifications:
^ 0.5 �mm or less slant from front wheel to back wheel of the Beamsetter -A-.
^ 1 mm or less slant per meter for the length of the vehicle -B-.
- Clean headlight lenses.
- Adjust vehicle tire pressure to specifications.
- Have a second Technician sit in the driver's seat while aiming the headlights.
- Bounce front and rear of vehicle up and down several times to settle vehicle suspension.
^ Vehicles without Xenon headlights, go to "Headlight aiming all vehicles" see page 3.
^ Vehicles with Xenon headlights, see below.
Vehicles with Xenon headlights
Headlight control motor basic settings MUST be performed prior to aiming headlights as follows (NO DTC's stored in headlight DTC memory):
- Connect the VAG 1551 or VAS 5051 scan tool.
- Switch ignition ON
^ For "Setting basic settings using VAS 5051 see page 7".
^ For "Setting basic settings using VAG 1551" scan tool, see below.
DO NOT remove scan tool at this time.
Headlight aiming all vehicles
Aim vehicle headlights using the VAS 5107 (Hella Universal Beamsetter IV) and the following procedure:
Driver's side headlight, adjusting low beam setting
- Move Beamsetter into position in front of the vehicle so it is aligned with the vehicle and Beamsetter box is 30 to 70 cm (12 to 28 in.) from the driver's side headlight.
- Switch headlights ON in low beam position.
- Align Beamsetter box so it is centered on the headlight (align vertically the horizontally).
Note:
^ Use the arrows on the Beamsetter box as a guide.
^ You may want to use a straight edge or tape measure, because setting must be within 3 cm (1.2 in.) of the center of the headlight.
- Without moving the Beamsetter, slide Broad-band sight toward center of vehicle (Broad-band sight can also be moved up and down for a better position).
Use Broad-band sight to make final alignment of Beamsetter box to vehicle by:
- Loosening hand-wheel that locks column in place.
- Sighting down through the slit in the Broad-band sight and rotating Beamsetter box and column until two similar points on vehicle are aligned.
Note:
Try using corners of the headlight housings or two screws that are the same height and as far apart as possible on the vehicle.
- Carefully tighten hand wheel without changing Beamsetter position.
- Find correct State or Province inclination % specification for the low beam adjustment (If there is no local specification, use 1.2%).
Note:
DO NOT use the inclination % molded into the plastic of the headlight housing near the headlight adjustment screws; it is for Europe only! (Consult Repair Manual, Maintenance of appropriate model to determine location of headlight adjuster screws.)
- Set Beamsetter "Scaled Wheel" to the proper low beam inclination %.
- Adjust height (vertical) setting first. Turn headlight height adjuster screw to align the upper edge of the flat portion of the beam with the center horizontal line of the grid on the Beamsetter pattern screen.
Note:
VOL is the correct beam pattern for both right and left headlights.
- Adjust lateral (horizontal) setting of driver's side headlight so that the breakaway point (beginning of the angle) of the headlight beam pattern aligns with the center of the target box of the grid on the pattern screen (it should match the VOL pattern shown on the Beamsetter box).
Note:
If the height setting changed, readjust.
Driver's side headlight high beam setting, checking
- Switch headlights ON in high beam position.
- Realign Beamsetter box with the high beam headlight if necessary.
- Set Beamsetter "Scaled Wheel" to 0%.
- Cover low beam lamp (use hand or small piece of cardboard) and check that the "hot spot" of high beam pattern is centered on the square target box of the pattern screen.
Note:
High beam pattern is built into the reflector design and cannot be adjusted separately If high beam pattern is way out of adjustment:
- Inspect for reflector damage.
- Replace reflector if needed.
Note:
Always aim headlight in the low beam position.
Fog lamp, aiming
- Switch fog lamps ON.
- Align Beamsetter box with fog lamp (make sure it is between 30 and 70 cm from the fog lamp lens).
- Set Beamsetter Scaled Wheel to 1.4%.
Adjust fog lamp so the top of the beam pattern aligns with the centerline of the target grid on the beam pattern screen.
Passenger's side headlight, aiming
- Move Beamsetter to the passenger side of the vehicle and follow the same procedures to align the Beamsetter box to the headlight.
- Aim headlight low beam, check the high beam and aim the fog lamp.
Note:
Make sure to reset the Beamsetter "Scaled Wheel" to the proper setting each time you change from low beam to high beam or to fog lamp.
- Ensure that headlights and vehicle body are clean and free of fingerprints.
Once headlights are adjusted:
^ Vehicles without Xenon headlights procedure is now complete.
^ Vehicles with Xenon headlights where the VAS 5051 was used to set basic settings go to "Setting basic setting using VAS 5051 (cont.)" see page 7.
^ Vehicles with Xenon headlights where the VAG 1551 scan tool was used to set basic settings, see below.
Setting basic settings using VAG 1551 (Cont.)
- Press the button.
- Press buttons 0 and 4 "Function 04 Basic setting".
Note:
If this is not done, DTC "Headlights not adjusted" will be stored in DTC memory
Setting basic settings using VAS 5051
- Select Vehicle Self Diagnosis
- Select Vehicle System: 55-Headlight Range Control.
- Select Diagnostic Function: 04-Basic Setting.
- Enter Display group 1.
- Press Q button to confirm input.
The vehicle will now define the headlight range of movement and set headlight in the basic setting while displaying the following: "Wait", "set Headlight Light"
- Go to "Headlight aiming all vehicles"
Setting basic settings using VAS 5051 (cont.)
- Press (<) once.
- Enter Display group 2
