1. COMPONENTS OF THE XENON BULB SYSTEM
The system consists of the following components:
–Front vehicle level sensor (the xenon bulb computer is built into this sensor).
–Rear vehicle level sensor.
–Right and left-hand headlight adjustment motor.
–Bulb high-voltage power unit (ballast).
–Xenon bulbs.
The K line can be used for fault finding. The system is not multiplexed.
2. SYSTEM OPERATION
When the control lever is in position (dipped headlights), it sends a signal to the UCH. The UCH processes the signal
and, through the CAN network, asks the Protection and Switching Unit to turn on the xenon bulbs.
When the bulbs come on, the adjustment motor moves through three positions: low, high, initial.
This is its initialisation.
If the vehicle is travelling above 6 mph (10 km/h) when the bulbs come on, there is no initialisation.
The computer manages various signals to adjust the amount of light:
–Vehicle speed: Signal provided by the ABS computer. Above 18 mph (30 km/h), the adjustment motors raise
the bulbs to provide optimum lighting for the driver.
–Vehicle front and rear height: signals from the front and rear height sensors. These sensors track the angular motion
of the vehicle's body (deceleration, acceleration, vehicle loaded). The computer then controls the motors to adjust
the beam and provide optimum lighting.
–System initialisation:
When the vehicle is unlocked, even if the dipped headlights are off, the system moves the adjustment motors
to the low position and then the initial position.
This initialises the system.

3. CONFIGURATION-CALIBRATION OF THE SYSTEM
To calibrate and configure a new computer on a vehicle, follow the configuration procedures in the following order.
a. Vehicle type (CF003)
This configuration activates the adjustment strategies designed for the body type.
The new strategies only take effect after the ignition is switched off and the doors are locked.
Perform configuration as follows:
–Enter the xenon bulbs fault finding mode.
–Make sure that the initial vehicle position indicated by the front and rear sensors is within the allowed range.
–Run configuration CF003 according to the vehicle type:
– Scénic II Strd* (5-seater MPV)
– Scenic II Long (7-seater extended MPV)
– Espace IV
– Velsatis
– Laguna II
–Exit fault finding mode.
–Switch off the ignition.
–Lock the doors using the card.
–The vehicle type has been programmed.
–After unlocking the doors, turn the ignition back on.
–See that the vehicle type has been properly identified by reading configuration LC001, Vehicle type.
b. Computer calibration (CF001)
This calibration must be performed when a system component is replaced (e.g. sensor, headlight etc.).
It enables the computer to store the vehicle's reference level.
To ensure proper configuration and calibration, follow this procedure:
–Check tyre pressure and adjust if faulty.
–Park the vehicle on a level surface under normal driving conditions (luggage compartment empty).
–Vehicle stopped, solid base (no door rattling).
–Driver on board.
–Fuel tank full.
Once computer calibration has been performed, check conformity of the light beam.
If it is incorrect, adjust the headlights manually.

AFTER REPAIRTurn on dipped-beam headlights.
Check that the system performs its initialisation to verify that the computer has no
faults.
Adjust the headlights manually.
CF001COMPUTER CALIBRATION
NOTESThis configuration enables the computer to store the vehicle's reference level.
Begin by configuring the vehicle type; then calibrate the vehicle level.
The vehicle must be stationary. Also, the front and rear sensor values must be within
the permissible range.
To calibrate the computer, proceed as follows:
–Check tyre pressure and adjust if faulty.
–Park the vehicle on a level horizontal surface.
–Make sure that the headlights have been properly adjusted manually.
–Position the vehicle with the wheels set straight ahead, engine switched off, driver behind the wheel and dipped
headlights on.
–Turn on the ignition and enter xenon bulbs fault finding mode.
–Select Configuration mode.
–Run configuration CF001.
–When calibration is complete, exit fault finding mode.
–Lock and unlock the vehicle doors with the card.
–The computer has now been calibrated.
–Check status LC010, which should indicate Completed.
LC010COMPUTER CALIBRATIONNot completed
Completed
The configuration reading LC010 can have either of two statuses:
–Not completed: The computer has not been calibrated, the vehicle's reference level is unknown, and the
maximum and minimum body height levels have not been programmed.
–Completed: The computer has been calibrated. Normal system operation. The sensor reference levels have
been programmed.

NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Confirm that initialisation is performed when the dipped headlights are switched on.
If it is not, the actuators or a circuit component may be defective.
Check the condition of fuse F1K (5A) located in the vehicle's glovebox.
Repair if necessary.
Run command AC012 Check actuator high and low position to find out which headlight is faulty.
Check for mechanical blockage of the headlight (ball joint popped out, reflector stuck, actuator seized).
Make sure that the sensors are properly positioned and mounted on the body, and check the condition
of the linkage.
If all the checks described above fail to solve the fault, replace the faulty adjustment motor(s).
