Xenon Headlight Testing

Xenon Headlight Testing


WARNING: Xenon headlight control systems generate high output voltage. Prior to head-light removal or testing observe the vehicle warning labels and be cautious by following safeguards to prevent accidental injury.

Xenon headlight systems (control module, igniter and bulb) produced prior to 9/98 can be tested with Special Test Adapter (P/N 90 88 6 631 000) in conjunction with the DIS Pre-set Measurements System.

The DIS Measuring System includes all of the cable connection information and procedures for the test.

Generation III Xenon lights on vehicles produced after 9/98 are tested with a different tool. Xenon test adaptor P/N 90 88 6 631 010 is used along with DIS/MoDiC pre-set measurements "Xenon lights after 9/1998".



The Generation III test adaptor uses the 50 amp test cable with both the MoDiC or DISplus.

In addition to the Measurement System tests there are also Test Modules available in the Diagnosis Program to diagnose vehicles with Generation 3 Xenon lights.
