Safety precautions
The voltage in the power supply circuit of the xenon headlight system reaches 28,000 V. Before working on the headlights, they must be switched off. Failure to comply with this requirement may result in death.
When working with the xenon headlight system, the following precautions should be observed.
- DO NOT carry out any work on xenon headlights or circuits unless they are de-energized.
- Work with xenon lamps is only permitted with the use of personal protective equipment, such as gloves and glasses. Do not touch the glass bulb of the lamp.
- The lamp can only be turned on when it is in the installed position, in the reflector.
- To avoid injury, all safety rules and instructions must be followed.
CAUTION: Disposal of xenon lamps must be carried out in accordance with hazardous waste disposal regulations.
The repair manual provides instructions on repair procedures for the xenon headlamp system, see section 100-00 General Information, Standard Repair Operations in the repair manual.
Inspection and verification
1. Be aware that intermittent fault messages may be caused by the cyclic behavior of the field effect transistors (FETs).

2. Perform a visual inspection for obvious mechanical or electrical problems.

3. If a clear cause for the problem observed or described by the customer is identified, correct it (if possible) before moving on to further actions.
4. Before moving on to the table signs of malfunction or dTC code index, using the manufacturer approved diagnostic system or scan tool, retrieve the stored diagnostic trouble codes (DTCs).
Since DTCs are stored in multiple blocks, it is recommended to perform a full vehicle data readout. Clear all DTCs after troubleshooting.
