1. SCOPE OF THIS DOCUMENT
This document presents the fault finding method 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.
Type of diagnostic tools
– CLIP + multiplex line sensor
Special tooling required
3. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
– It is forbidden to carry out a road test with the diagnostic tool in dialogue with the ECU because the ABS
and Electronic Brake Distribution functions are deactivated. Braking pressure is identical on both axles of
the vehicle (risk of a spin under heavy braking).

Procedure
To run fault finding on the vehicle computers, switch on the ignition. Connect the diagnostic tool and perform the
required operations.
SCENIC II and MEGANE II:
To run fault finding on the vehicle computers, switch on the forced + after ignition feed.
Proceed as follows:
LOGAN, SANDERO, DUSTER, MASTER II ph2 and ph3, THALIA 2/SYMBOL 2, CLIO II F6, KANGOO VLL
To run fault finding on the vehicle computers, switch on the + after ignition feed.
Proceed as follows:Switch on the forced + after ignition feed:
– with the vehicle card in the card reader,
– press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
– connect the diagnostic tool and perform the required operations.
Switching off the forced + after ignition feed:
Press the Start button twice briefly (less than 3 seconds).
Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument
panel have gone out.
For vehicles with key/radiofrequency remote control unit,
switch on the ignition with the key.

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 status of faults must be considered when the diagnostic tool is used after the + after ignition
feed is switched on (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 in the Notes section 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 these lines (for oxidation, bent pins, etc.),
– the resistance of the faulty component,
– the condition of the wires (melted or split insulation, wear).
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 processed by
customer complaints.
A summary of the overall procedure to follow is provided on the following page in the form of a flow chart

5. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring 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.
Physical inspection
While manipulating the wiring, 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 the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check 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 with another wire.
If a fault is detected, repair or replace the wiring harness.

6. FAULT FINDING LOG
You will always be asked for this log:
• when requesting technical assistance from Techline,
• for approval requests when replacing parts for which approval is mandatory,
• 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.
7. INSTRUCTIONS TO BE FOLLOWED FOR ANY WORK CARRIED OUT ON THE INJECTION SYSTEM
Instructions to be followed before opening of the fuel circuit
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
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.
Blast compressed air over the cleaned parts (tools, workbench, and the parts, unions and injection system area).
Check that no bristles remain.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves cover them with latex gloves to prevent contamination.
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. Ambient air carries impurities.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once they
have been plugged.
The use of a brush, cleaning agent, bellows, sponge or normal cloth is strictly forbidden 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.IMPORTANT!IMPORTANT
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 COMPULSORY TO COMPLETE A FAULT FINDING LOG
EACH TIME IT IS REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.

the computer.
– Switch off the ignition and remove the computer.
Before replacing the computer, switch off the ignition and wait 1 minute for the system to shut down completely.
Note the current configuration of the computer by reading the configuration LC001 External GPS aerial.
Procedure to be applied after repair:
After replacing the computer, apply the programming command VP001 Enter VIN, check the computer configuration
using LC001 External GPS aerial, LC002 Timed + battery feed and LC003 Alarm and configure the new
computer if necessary using CF001 CONFIGURE SVT.

Conditions for applying the fault finding procedure to stored faults:
The fault is declared present if the battery voltage is X < 3.5 V after 5 voltage checks.
Check the voltage and the battery connections, component code 107.
Repair if necessary.
If the fault is still present and the internal battery is currently charging, wait for approximately 2 hours so that the
internal battery voltage is X > 3.5 V.
If the fault is still present, replace the anti-theft tracking unit, component code 2186 (see MR 388, 451, 364, 370,
377, 423, 430 or 374, Mechanical, 82A, Immobiliser, Tracking unit: Removal - Refitting).
