Overview

Three types of headlamp are available: Halogen, bi-xenon or adaptive front lighting system (AFS).

For information on the description and operation of the systems, refer to section 417-00 - Exterior Lighting of the workshop manual.

Given the potential for personal injury, the following safety information should be followed at all times:

Safety information

  : The xenon headlamp system generates up to 28,000 volts. Make sure that the headlamps are switched off before working on the system. Failure to follow this instruction may result in personal injury.

The following safety precautions must be followed when working on the xenon headlamp system:

. DO NOT attempt any procedures on the xenon headlamps when the lights are switched on.

. Handling of the xenon bulb must be performed using suitable protective equipment, e.g. gloves and goggles. The glass part of the bulb must not be touched.

. Xenon bulbs must be disposed of as hazardous waste.

. Only operate the lamp in a mounted condition in the reflector.

There are comprehensive instructions on the correct procedures for xenon headlamp system repairs in the manual, refer to section 100-00 - General Information, Standard Workshop Procedures of the workshop manual.

Inspection and verification

. Verify the customer concern.
  Note that intermittent fault reports may be due to the cycling operation of the field effect transistors (FETs)

. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index.
  Because the DTCs are stored in more than one module, a complete vehicle read is recommended
