Procedure
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
–Renault card in the card reader (keyless vehicle scenario 1, entry level, not hands-free and scenario 2, top of the
range, hands-free),
–press and hold Start button (longer than 5 seconds) with start-up conditions not fulfilled,
–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.

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).

Check that the system performs its initialisation to verify that the computer has no
faults.
Adjust the headlights manually.

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.
