- The pressure for the headlamp range adjustment can be measured on the pressure valve block (4). The pressure valve block (4) is located in the right component compartment.
- Allow engine to run.
- Set headlamp range adjustment to individual positions and read off pressure values. If the nominal value is not reached, perform leakage test.
If the connection sockets are leaky they can be replaced by adapters (8). For this purpose separate pneumatic line (9) from control switch (7) and shorten by 50 mm. Install adapter (8) instead of cut connection socket and connect to hose connector (approx. 40 mm long).
