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.

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.

NOTESThe fault is declared present after the dipped headlights are switched on, or during
a road test.
C.O
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
bulb computer.
If the fault is still present after these checks, replace the dipped headlights control stalk.
