1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this document):
– Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
– Visu-Schéma (CD-ROM), paper.
Type of diagnostic tools
–CLIP
Special tooling required
3. REMINDERS
Procedure
To save energy, the vehicle's UCH interrupts the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the following
procedure:
– press the unlocking button on the card,
– insert the card in the reader,
– press the start button (interrupting the timed + after ignition feed mode),
– press the start button for more than 5 seconds, without conditions for starting being met, until the immobiliser
warning light flashes rapidly (4 Hz).
This forced + after ignition feed mode is active for 1 hour.
Pressing the start button or removing the card from the card reader interrupts the forced + after ignition feed, but
does not interrupt the time period for the forced + after ignition feed. Until one hour has elapsed, activating the +
after ignition feed will restart forced + after ignition feed for the remaining time. Vehicle(s): MEGANE II phase 2, SCENIC II

Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored fault status must be considered, when the diagnostic tool is used after switching on the +
after ignition feed (without operating 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 instructions 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 for this connection,
– the resistance of the faulty component,
– the condition of the wires.
Conformity check
The purpose of the conformity check is to check data that does not produce a fault on the diagnostic tool if the data
is inconsistent. Therefore, this stage is used to:
– carry out 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 repair.
The conformity check is a fault finding procedure carried out using the interpretation of statuses and parameters.
If a status does not function normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page (see interpretation of statuses and parameters).
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be dealt with by
customer complaints
A synopsis of the general 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 may temporarily clear the cause of a fault.
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the protectors, insulation, and routing of the wiring, as well as the mountings.
Physical inspection
When working on wiring, use the diagnostic tool to highlight a change in the status of the faults, from a "stored"
fault to a "present" fault, or use the multimeter to view the status changes.
Make sure that the connectors are firmly secured.
Apply light pressure to the connectors.
Twist the wiring harness.
Checking insulation to earth
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5V. The correct measured value is 0V.
Checking insulation in relation to + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value is 0V.
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result is: 1 Ω ± 1 Ω for each connection. The line must be fully checked,
and the intermediate connections are only included in the method if this saves time during the fault finding
procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured value
should be 1 Ω ± 1 Ω.
Power supply check
This check can be carried out using a test light (21 W or 5 W depending on the maximum permissible load).

4.1 Connector check
1. Visual inspection of the connection:
– Check that the connector is connected correctly and that the male and female parts of the connection are correctly
coupled.
2. Visual inspection of the area around the connection:
– Check the condition of the mounting (pin, strap, adhesive tape, etc.) if the connectors are attached to the vehicle.
– Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
– Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating material
(wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
3. Visual inspection of the plastic casing:
– Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, terminal locations, etc.).
– Check that there is no heat damage (casing melted, blackened, deformed, etc.).
– Check that there are is no dirt (grease, mud, liquid, etc.).
4. Visual inspection of the metal contacts:
(The female contact is called CLIP. The male contact is called a TAB).
– Check that there are no bent contacts (the contact is not inserted correctly and can come out of the back of the
connector). The spring contact of the connector when the wire is pulled slightly.
– Check that there is no damage (tabs bent, clips open too wide, blackened or melted, etc.).
– Check that there is no oxidation on the metal contacts. Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of a poor
electrical contact. Restrict the number of connections/disconnections as far as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be 2 types of connections:
– Connector/Connector.
– Connector/Device.

Visual inspection of the sealing:
(Only for watertight connectors)
Check for the seal on the connection (between the 2 parts of the connection).
– Check the seal at the back of the connectors:
– For unit joints (1 for each wire), check that the unit joints are present on each electrical wire and that they are
correctly positioned in the opening (level with the housing). Check that plugs are present on openings which are
not used.
– For a grommet seal (one seal which covers the entire internal surface of the connector), check that the seal is
present.
– For gel seals, check for gel in all of the openings without removing the excess or any protruding sections (it does
not matter if there is gel on the contacts).
– For hotmelt sealing (heat-shrink sleeve with adhesive), check that the sleeve has shrunk correctly on the back of
the connectors and electrical wires, and that the hardened adhesive is evident from the wire ends.
– Check that there is no damage to any of the seals (cuts, burns, significant deformation, etc.).
If a fault is detected, consult Technical Note 6015A, Repairing electrical wiring.
5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from the Techline,
●when requesting approval before replacing parts for which approval is compulsory,
●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 INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.IMPORTANTIMPORTANT
All faults involving a complex system call for thorough diagnostics 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.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.

1. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks caused by the introduction of
contamination are:
– damage to or destruction of the high pressure injection system,
– a component seizing up,
– a component losing its sealing.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles
a few microns in size) should have penetrated the system during dismantling.
The cleanliness guidelines must be applied from the filter through to the injectors.
What are the sources of contamination?
– metal or plastic swarf,
– paint,
–fibres:
– from cardboard,
– from brushes,
– from paper,
– from clothing,
– from cloths,
– foreign bodies such as hair,
– the ambient atmosphere,
–etc.
2. INSTRUCTIONS TO BE FOLLOWED PRIOR TO ALL OPERATIONS
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create faults in the electrical connections.
IMPORTANT
Before carrying out any work on the high pressure injection system, protect:
– the accessories and timing belts,
– the electrical accessories, (starter, alternator, electric power-assisted steering pump),
– the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are to be used once only, and discarded after use.
Obtain lint-free cleaning cloths (cloth part number 77 11 211 707). Using normal cloth or paper is prohibited. They
are not lint-free and could contaminate the fuel circuit. A lint-free cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into a clean receptacle.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.
Blow compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system zones). Check
that no bristles are left.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves cover them with latex gloves to prevent contamination.
3. INSTRUCTIONS TO BE FOLLOWED DURING THE OPERATION
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system. The
plugs to be used are available from the Parts Department. The plugs must not be reused under any circumstances.
Seal the pouch shut, even if it has to be opened shortly afterwards. The ambient atmosphere carries contamination.
All components removed from the injection system must be stored in a hermetically-sealed plastic bag once the
plugs have been inserted.
Using a brush, cleaning agent, air gun, brush or normal cloth is strictly prohibited once the circuit has been opened.
These items could allow contamination to enter the system.
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the vehicle.
