IMPORTANT

• Never switch on a bulb that is not installed in its headlamp (danger to eyes).
• Xenon bulbs operate at 20000 V on ignition, then at 85 V AC in operation.
• Wait for the control unit and ballast assemblies to cool down before removal.
• Always disconnect the battery before any work.

REMOVAL

• Disconnect the battery.
• Remove the headlamp.
• Place the headlamp on a clean cloth to avoid scratching it.

• Remove the fixing screws (1) of the power module control unit.
• Disconnect the connectors.

INSTALLATION

WARNING

• The high-voltage harnesses for the right and left headlamps are different (brown connector for the left headlamp and blue for the right headlamp).
• Always replace the sealing gasket when replacing the control unit.

• Tighten the power module control unit to torque (1.2 daN.m).

WARNING

After replacing a control unit, it must be taught the following:

• position CF004 (example: left optical unit),
• configuration CF003 (example: B - C - K - E).

• Switch off the dipped beam headlamps so that the control unit validates the configurations.
• Switch on the lights.
• Enter diagnostic mode.
• Check that the configurations have been accepted.

Note: Always perform an initialisation of the xenon lamp system (Chapter Xenon Lamps, Xenon Headlamps: Adjustment, page 80C-14) and adjust the headlamps.
