SUBJECT:
Bi-Xenon Headlamp Ballast
REFERENCE:
VADIS
DESCRIPTION:
Under certain conditions, ballasts in vehicles equipped with Bi-Xenon headlamps may not function.
The ballast functions as the voltage regulator and generates alternate current. It transforms the vehicles current from 12V to 1,000V during start-up. Once the bulbs are lit, it then reduces the voltage to 100V. Its main tasks are to light the bulbs and to control the light during operation.
A new improved ballast has been introduced into production from the chassis break shown.
SERVICE:
When a vehicle with Bi-Xenon headlamp is not functioning properly and it is below the chassis break listed above.
First check the ballast in the vehicle to be sure that it is Rev D as shown in the photos. If it is not a Rev D ballast, replace it with the new spare part, P/N 30674786.
