–connect the diagnostic tool and perform the required operations.
To cut off + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–Press the start button twice briefly (less than 3 seconds),
–Check that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument
panel have gone out. Vehicle(s): Scénic II, Laguna II ph1, Velsatis

Faults
Faults are classed as either present or stored (having appeared in a certain situation and then disappeared, or being
still present but not diagnosed in the current situation).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
following + after ignition feed being activated (without any system components being active).
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 instructions in 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 electric lines on which there is a fault;
–The connectors on those lines (corrosion, bent pins, etc.);
–The resistance of the faulty component;
–The condition of the wires (insulation melted or split, chafing, etc.).
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 when they are inconsistent. Therefore, this stage is used to:
–perform fault finding on faults that do not have a fault display, and 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 repairs.
This section features the fault finding procedures for statuses and parameters, and the conditions for checking 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 diagnostic tool check is correct, but the customer complaint is still present, it should be dealt with according
to the customer complaint.
Asummary of t he overall procedure t o f ollow is provided on the following page in the form of a flow cha rt.

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.
Check the 1K (5A) fuse of the passenger compartment relay and fuse box.
Replace it if necessary.
Turn on dipped-beam headlights.
If the bulbs light but the system does not perform initialisation and no communication is possible, perform the
following checks:
Remove the timed power supply 40A relay A located in the passenger compartment fuse and relay box.
Check the condition of the connections and repair if necessary.
Measure the following resistance values:
–Power circuit: Resistance between tracks 85 and 86 of the relay.
If the resistance is not 65 ± 5 ΩΩ Ω Ω
, replace relay A.
–Control circuit: Resistance between tracks 30 and 87A of the relay.
If the resistance is not approximately 1 ΩΩ Ω Ω
, replace relay A.
Check the battery voltage and carry out the operations necessary to obtain a suitable voltage (9.5 V < battery
voltage <14.4 V).
Check for:
a + 12 V supply before ignition on track 16 of the diagnostic socket,
a + 12 V supply after ignition on track 1 of the diagnostic socket,
earth on tracks 4 and 5 of the diagnostic socket.
Repair if necessary.
If the fault is still present, contact the Techline.
