Headlamps, Checking Adjustment
Special tools and workshop equipment required
During inspection, the check is merely a shortened version of a headlamp adjustment test, which is due, for example, after repairs and does not replace this one.
Vehicle load and tire pressures do not need to be adjusted.
A basic setting for the headlamps does not need to be performed via the Vehicle Diagnostic Tester.
According to the service information specification, the checking and adjusting of the headlamps is a repair procedure and should be charged separately.
Procedure:
-- For vehicles with manual headlamp range control, set the adjusting mechanism to the basic setting.
-- Activate the low beam.
-- Align the headlamp adjusting unit parallel to the vehicle and place it at a distance of 30 to 70 cm -dimension a- centered in front of the headlamp. The maximum deviation from the center point of the light-emitting surface is 3 cm -dimension b-.
-- Adjust the angle of the headlamp adjusting unit so that the headlamp light distribution on the testing surface meets the following specification: horizontal cut-off line on the separating line -1-.
-- Read the set angle value of the headlamp adjusting unit.
-- Repeat the procedure on the other side.
-- Compare the left and right angle values.
-- If they vary from each other by 2.0% or higher, check and adjust the headlamp adjustment according to the service information specifications. Refer to HEADLAMP, ADJUSTING .
