Xenon Headlamps: Adjustment

Any operation on a xenon headlamp, on a sensor or on a suspension component requires an initialisation followed by adjustment of the headlamps.

• Place the vehicle on a flat, level surface.
• Inflate the tyres to the correct pressure.
• Open the bonnet.
• Make sure the luggage compartment is empty.

• Do not apply the parking brake.
• Do not get into the vehicle while the operation is in progress.

ADJUSTMENT

• Switch on the dipped beam headlamps.
• Connect the diagnostic tool.
• On the diagnostic tool, select the "discharge lamp" system of one of the headlamps (left or right).
• Check that there are no faults.
• Select command CF001 "Calibrate control unit".
• Exit diagnostic mode.
• Switch off the dipped beam headlamps (the control unit validates the initialisation).
• Repeat the procedure for the other headlamp.

• Switch the dipped beam headlamps back on.
• Place a headlamp aimer set to -1.3 % (value marked on the headlamp) in front of the vehicle.
• Adjust the headlamps using access point (1).

The initialisation may fail:

• when the control module(s) configured in the headlamp(s) are not located (addressing),
• when the vehicle speed is not zero,
• when there is a sensor fault (no signal or inconsistent signal),
• when there is no configuration in the control module (vehicle type: K, L, E...).
