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

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.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after 60 seconds, with the ignition on.
Special notes:
Check the consistency between the instrument panel display and parameter PR035
Fuel level.
CO
NOTESSpecial note:
The fault is declared present if the fuel sender resistance is
greater than 350 Ω.
Manipulate the wiring harness between the instrument panel and the fuel sender in order to produce a change in
fault status (Present → Stored).
Look for possible damage to the harness, and check the connection and condition of the fuel sender and its
connections.
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Check the continuity of the following connections:
Fuel sender track 2 track 15, Grey instrument panel connector
Fuel sender track 4 track 2, Grey instrument panel connector
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Measure the resistance between tracks 4 and 2 of the fuel sender.
Replace the fuel sender if the resistance value is not: 290 Ω fuel tank in reserve
54 Ω fuel tank full
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

Manipulate the wiring harness between the instrument panel and the fuel sender in order to produce a change in
fault status (Present → Stored).
Look for possible damage to the harness, and check the connection and condition of the fuel sender and its
connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Disconnect the fuel sender connector and check for a change in fault status.
If the fault remains in short circuit, check the insulation and continuity of the following connections, with the
connector disconnected:
Fuel sender connector track 2 track 15, Grey instrument panel connector
Fuel sender connector track 4 track 2, Grey instrument panel connector
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault becomes an open circuit fault, move to the next step of the fault finding.
Measure the resistance between tracks 4 and 2 of the fuel sender.
Replace the fuel sender if the resistance value is not: 290 Ω fuel tank in reserve
54 Ω fuel tank full
If the fault is still present, contact the Techline.
