Faults: Faults are declared as either present or stored
(depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been
diagnosed within the current context). The present or stored status
of faults should be taken into consideration when the diagnostic
tool is used following the + after ignition supply being switched
on (without acting on the system components). For a present fault,
apply the procedure described in the Interpretation of faults
section. For a stored fault, note the faults displayed and apply
the notes section. If the fault is confirmed when the notes are
applied, the fault is present. Deal with the fault If the fault is
not confirmed, check: the electrical lines which correspond to the
fault, the connectors on these lines (corrosion, bent pins, etc.),
the resistance of the component detected as faulty, the condition
of the wires (melted or split insulation, wear). Conformity check:
The aim of the conformity check is to check statuses and parameters
that do not produce a fault display on the diagnostic tool because
they are inconsistent. Therefore, this phase is used to: run fault
finding on faults which are not displayed but which may correspond
to a customer complaint, check that the system is operating
correctly and that there is no risk of a fault recurring after
repair. This section provides the fault finding procedures for
statuses and parameters and the conditions for testing them. If a
status is not behaving normally or a parameter is outside the
permitted tolerance values, consult the corresponding fault finding
page. Customer complaints - Fault finding chart If the check using
the diagnostic tool is all clear, but the customer complaint is
still present, the fault should be dealt as a Customer complaint. A
summary of the overall procedure to follow is provided on the
following page in the form of a flow chart

4. FAULT FINDING PROCEDURE (continued) Wiring check: Fault
finding problems: Disconnecting the connectors and/or manipulating
the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are
generally correct, especially if the fault is not present when the
analysis is made (stored fault). Visual inspection: Look for damage
under the bonnet and in the passenger compartment. Carefully check
the fuses, insulators and wiring harness routing. Look for signs of
oxidation. Tactile inspection: While manipulating the wiring
harness, use the diagnostic tool to note any change in fault status
from stored to present. Make sure that the connectors are properly
locked. Apply light pressure to the connectors. Twist the wiring
harness. If there is a change in status, try to locate the source
of the fault. Inspection of each component: Disconnect the
connectors and check the appearance of the clips and tabs, as well
as their crimping (no crimping on the insulating section). Make
sure that the clips and tabs are properly locked in the sockets.
Make sure that no clips or tabs have been dislodged during
connection. Check the clip contact pressure using an appropriate
model of tab. Resistance check: Check the continuity of entire
lines, then section by section. Look for a short circuit to earth,
to + 12 V or to another wire. If a fault is detected, repair or
replace the wiring harness.

5. FAULT FINDING LOG NOTE Any fault on a complex system requires
thorough fault finding with the appropriate tools. The FAULT
FINDING LOG, which should be completed during the fault finding
procedure, ensures a record is kept of the procedure carried out.
It is an essential document when consulting the manufacturer.
IMPORTANT!
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH
TIME FAULT FINDING IS CARRIED OUT. You will always be asked for
this log: when requesting technical assistance from the Techline.
for approval requests when replacing parts for which approval is
obligatory. to be attached to monitored parts for which
reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts
removed.
6. SAFETY GUIDELINES All work on components requires the
observation of safety rules to prevent damage or injury: Check that
the battery is properly charged to avoid damaging the computers in
the event of a low load. Do not smoke. Use the appropriate tools.
Do not touch the xenon bulbs, and do not work on the xenon bulb
system when it is in operation, as the voltage can be more than
20,000 V.

1. System description: The system on which a fault finding is
being performed is fitted with xenon bulbs. This system allows:
dynamic adjustment of headlights (xenon bulb function).
2. System layout: Xenon bulb function: The system comprises: a
computer to manage information and control the actuators a front
height sensor mounted on the front axle to measure vehicle body
height variations a rear height sensor mounted on the rear axle to
measure vehicle body height variations 2 adjustment motors mounted
inside the headlights 2 voltage transformers (ballast) which cannot
be diagnosed 2 xenon bulbs located inside the headlights which
cannot be diagnosed.
3. Operation programming Xenon bulb function: The user requests
that the dipped headlights are switched on by pressing on the
control stalk. The driver request is received by the UCH which
sends it to the computer via the vehicle multiplex network. The
xenon bulb computer operates the headlight adjustment motors.
Initialisation: When the xenon bulbs come on, the headlights run
through initialisation. This function consists of operating the
actuators to three different beam heights. The driver is notified
that the system is operating correctly. If the computer is faulty,
the initialisation is not performed when the bulbs are switched on.
Initialisation is performed if the following conditions are
fulfilled: stalk in dipped headlights position system initialised
vehicle stationary or speed < 6 mph (10 km/h).

Dynamic adjustment: This function allows adjustment of the xenon
bulb beam height as a function of variations in vehicle body height
and vehicle speed. This information is provided by: the front and
rear body sensors the ABS computer (speed signal via the multiplex
network) the longitudinal acceleration sensor The xenon bulb
computer operates the adjustment motors according to the
information received, thereby obtaining optimal beam
characteristics under all driving conditions. Raise/lower according
to speed: This function allows operation of the adjustment motors
to elevate the beam at a speed of more than 18 mph (30 km/h), to
optimise driving comfort. The beam is adjusted as a function of the
vehicle speed. If the vehicle speed is < 18 mph (30 km/h), the
adjustment motors lower the beam.

the recommendations specified in Workshop Repair Manual 364,
Section 35. Before any operation, ensure that all the wheels have
tyre pressure monitoring valves, and that the spare wheel has not
been fitted.
For faults DF006 to DF009, if the fault is present as of the
first kilometres, repeat programming of the 4 valves. If the
programming fails, replace the valve in question according to the
method described in the repair manual (Workshop Repair Manual 364,
Section 35B). Make sure that no wheel has a rubber valve. If there
is one, replace it by a wheel with a valve fitted with a sensor and
perform a road test. If the problem is still present, carry out
programming of the 4 valves. If the fault persists, replace the
valve. The correspondence between fault numbers and the valve
concerned is described below: DF006 = Front left-hand valve sensor
DF007 = Front right-hand valve sensor DF008 = Rear right-hand valve
sensor DF009 = Rear left-hand valve sensor Once the sensor has been
