Faults
Faults are declared either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of the faults should be taken into consideration when the diagnostic tool is used after
the + after ignition feed has been activated (without any of the system components being activated).
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 faulty component,
– the condition of the wires (melted or cut insulation, wear).
Conformity check
The purpose 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 repair.
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 permitted tolerance values, you should 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 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.
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
When handling the wiring, use the diagnostic tool to detect any change in the status of the faults from "stored" to
"present".
Make sure that the connectors are firmly secured.
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 the clips or tabs have not been bent back 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.

A) Make sure the water in diesel fuel detection sensor is properly connected.
– If not, clear the fault,
– Carry out a road test (speed >12 mph (20 km/h) and engine speed >1200 rpm) for more than 30 seconds.
– If the fault does not reappear, end of fault finding procedure.
– If the fault reappears, go to step B.
B) If the sensor is properly connected:
– Bleed the diesel filter unit (see MR 388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2) or
MR 374 (Kangoo VLL), Mechanical, 13A, Fuel supply, Diesel filter: Removal - Refitting).
– Clear the fault.
– Carry out a road test (speed >12 mph (20 km/h) and engine speed >1200 rpm) for more than 30 seconds.
If the fault does not reappear, end of fault finding procedure.
C) If the fault recurs:
Check the insulation and continuity of the following connections:
–3WT between components 120 and 414,
–M (or 3WU) between components 120 and 414.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia 2/
Symbol 2) or MR 374 (Kangoo VLL), Mechanical, 13A, Fuel supply, Diesel filter: Removal - Refitting).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds, to
confirm the repair.
Note:
When the water level in the fuel filter unit is below the sensor's electrodes, some driving conditions (turning,
inclines) may cause the injection fault warning light to come on erroneously (the sensor's off-centre position in the
fuel filter unit, combined with the driving condition, shows water detection, and hence the light comes on).
If the fault is still present, contact the Techline.
