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:

⇒ 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.
