Program No.: V010
Vdiag No.: 05
The xenon bulbs fitted to the system require a voltage of 20,000 V when switched on, then run on 85 V AC.
You must always disconnect the battery before doing any work on the headlights, bulbs, and high-voltage headlight
power transformer units.
To follow the method of removal-refitting of the constituent components of the system, see MR 370 (Scenic II)
or MR 361 (Espace IV) or MR 353 (Velsatis), Mechanical systems, 80C - Xenon Bulbs, Xenon bulb computer:
Removal – Refitting or MR 339 (Laguna II), Mechanical systems, 80 – Headlights, Xenon headlights.
It is forbidden to supply a bulb if it is not installed in the headlight (danger that you might damage your eyes).
The computer must be calibrated using CF001computer calibration (see Configuration and programming) each
time a front or rear level sensor is replaced.
The following procedure should be applied before adjusting the headlight beam:
–check that there are no faults
–configure the vehicle type using command CF003 Vehicle type (see Configuration and programming)
–calibrate the computer using command CF001 (see Configuration and programming)
Next adjust the headlights manually, (see MR 370 (Scenic II) or MR 361 (Espace IV) or MR 353 (Velsatis),
Mechanical systems, 80C - Xenon bulbs, Xenon headlight: Adjustment or MR 339 (Laguna II), Mechanical
systems, 80 – Headlights, Xenon headlights).

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.

NOTESThis configuration is performed after replacing the computer.
Configuration procedure:
–Connect the CLIP tool and turn on the ignition.
–Enter Xenon bulbs fault finding mode.
–Select configuration CF003 Vehicle type.
–Select the type of vehicle.
–Confirm the configuration.
–Exit fault finding mode and switch off the ignition.
–Lock and unlock the vehicle doors with the card.
–Re-enter "Discharge bulbs" fault finding mode and read LC001 "Vehicle type".
–See that the vehicle type has been properly identified by reading configuration LC001.

AC012ACTUATOR HIGH AND LOW POSITION CHECK
NOTESBefore running this command, make sure that the vehicle level has been calibrated.
This command tests actuator control following a malfunction or customer complaint.
Use the CLIP tool to check whether the xenon bulb computer has any faults.
If fault DF018 Actuator is present, consult procedure for dealing with DF018.
If the actuators fail to move after the command is run, proceed as follows:
–Check the continuity and absence of interference resistance between:
Right-hand adjustment motor track 2 track 7 of the discharge bulb computer
Left-hand adjustment motor track 2 track 7 of the discharge bulb computer
If necessary, repair the connections.
Check the condition of the adjustment motors and xenon bulb computer connections.
Repair if necessary.
If the command still fails to move the adjustment motors, replace them.

NOTESPriority when dealing with a number of faults.
Run a fault finding procedure on the UCH (see 87B, Passenger compartment connection unit) or UPC
(for Scénic) (see 87G, Engine compartment connection unit) to check the correct operation of the stalk.
Check the condition of the contacts and make sure that the xenon bulb computer is properly connected.
Check the continuity and absence of interference resistance in the following connection:
For Scénic II:
Black 6-track connector for the Protection and switching unit connector
track 5
For Vel Satis/Espace or Laguna II:
Black, 6-track connector of the UCH track 3B2Track 6 of the xenon
