Test pattern with dynamic main beam
Note
For dynamic main beam test pattern, headlights need to be
♦
reset to basic settings using vehicle diagnostic tester .
The basic settings can only be reset using vehicle diagnostic
♦
tester . After resetting, DLA main beam distribution is actuated
automatically.
Pay special attention to correct alignment of the adjustment
♦
sighting device on the headlight adjuster. Only when this has
been done can you adjust the headlights to ensure that they
do not dazzle other road users.
In vehicles with DLA the dipped headlight setting can be
♦
checked as an alternative.
DLA: "Dynamic Light Assist", dynamic high beam regulation.
♦
Check the following:
– Whether the horizontal light-dark border touches the separat‐
ing line -1- in the test area when the main beam is on.
– Whether the breaking point -2- between horizontal part of the
light-dark border on the right and the rising part on the left lies
on the vertical line of the central point -3-. The bright core of
the light beam must be to the left of the vertical line.
Note
The setup pattern applies only to the left headlight. The setup
pattern for the right headlight is a mirror image.
Test pattern with dipped headlights
Testing may also be carried out with dipped headlights switched
on. Nevertheless, said dynamic main beam test pattern is prefer‐
red.
For checking dipped headlight it is not necessary to use the ve‐
hicle diagnostic tester .
The headlight setting can also be carried out using the dipped
headlight test pattern.
– With the dipped beam switched on, the lowest part of the hor‐
izontal light-dark border must touch the dividing line -1- of the
test area
– The breaking point -2- between the horizontal part of the light-
dark border on the left and the slope on the right should be on
the vertical line passing through the centre mark.
