• Ignition on.
• Switch between high and low beam.

  If the left-hand Xenon lamp does not switch between high and low beam, the fault is permanent.

  If the left-hand Xenon lamp switches between high and low beam, the fault was present previously but is no longer active, intermittent fault.

Do the xenon lamps switch between high and low beam? 

• YES 

  OKAY:  Troubleshooting has been completed.

• NO
