Fault finding - Introduction
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 (CD-ROM), paper.
Type of diagnostic tools
–CLIP
Special tooling required
3. REMINDERS
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
–vehicle card in 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.
To cut off the + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–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 indicator lights on the instrument
panel have gone out.Vehicle(s): Scénic II

Fault finding - Introduction83A
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 the faults should be considered when the diagnostic tool is switched on after the +
after ignition feed is switched on (with no 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 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 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 data that does not produce a fault on the diagnostic tool when 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 repairs.
This section gives 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 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 general procedure is provided in the form of a flow chart
on the following page.

4. 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 to another wire.
If a fault is detected, repair or replace the wiring harness.

5. 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.
6. 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. IMPORTANT!IMPORTANT
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.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.

INSTRUMENT PANEL
Fault finding - System operation
Instrument panel functions (entry level and mid-range versions):
The instrument panel allows:
–display by needle gauge of the following information:
–Vehicle speed
–Rev counter
–Fuel gauge
–Engine coolant temperature
–Management of 20 warning/indicator lights
–Alphanumeric display of the following information:
–Total and trip mileage
–Oil level
–Messages (68 messages)
–Keyless vehicle messages
–Warning messages
–Management of a multifunction buzzer:
The buzzer is used for the following functions:
–Indicating the operation of the direction indicators.
–Signalling that the lights have been left on.
–Indicating that the driver's or passenger's seat belts are not fastened when driving.
–Indicating that a door or the tailgate is not correctly closed.
–Signalling that the handbrake is on.
–Indicating the low fuel warning.
–Indicating that a speed has been exceeded, for Arabian versions, where an overspeed warning
is legally required.
–Indicating to the driver that the automatic locking when driving has been activated/deactivated.
The following buzzers can sound:
–Side lights on
–Direction indicators
–Management and trip computer display:
–Trip meter
–Fuel consumed
–Average fuel consumption
–Instantaneous fuel consumption
–Fuel range in kilometres and miles
–Distance travelled in kilometres and miles
–Average speed
–Oil service interval in kilometres
–Oil service interval in time
–Programmed speed (if the cruise control and speed limiter feature is present).
–Instrument panel dimmer: when the lights are on, the brightness of the instrument panel can be adjusted
using a button located on the instrument panel.
–In the event that the childproof lock system is not working, the buzzer will sound and a warning message
will appear on the instrument panel.
In vdiag 08 (with program version 040B) and vdiag 0C, the instrument panel can manage a personalised oil service
interval (known as the OCS) by detecting premature oil wear (depending on the engine). If the engine has this oil
wear detection management function, the oil service interval will initially be increased. The oil service interval could
however decrease more quickly if a “severe” type of driving (urban driving, diving in traffic jams, etc.) is detected by
the injection computer. The instrument panel will display a message to request that an oil service be performed
quickly, without necessarily displaying a warning message beforehand.
