Main headlights with gas discharge
bulbs
Note
♦
Before working on gas discharge headlights, always switch off
the headlights and remove the ignition key.
♦
The automatic headlight range control on headlights with gas
discharge bulbs is equipped with self-diagnosis.
♦
When dealing with complaints, it is absolutely essential that
the function and operation of the lighting system is first under‐
stood.
♦
Additional information:
⇒ Operating instructions
⇒ Current flow diagrams, Electrical fault finding and Fitting loca‐
tions
Fault detection and fault display:
The automatic headlight range adjustment (HRA) and onboard
supply control unit have a self-diagnosis function, which makes
fault finding on the headlights using gas discharge lamps easier.
For fault finding, use the vehicle diagnosis, testing and informa‐
tion system -VAS 5051A- in “guided fault finding” mode.
