STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Check the conformity and quality of the fuel by running test 11 Diesel fuel conformity check.
Check the sealing of the tank and the low pressure circuit by running test 3 Low pressure circuit check.
A. Check that the water in diesel detection sensor is correctly 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 C.
b) If the water detection sensor is not present:
–Insulate the electrical connector not connected to the vehicle (risk of humidity, oxidation, and erratic
appearance of faults).
Check that the configuration reading LC065 Water in diesel fuel sensor is WITHOUT.
If LC065 Water in diesel fuel sensor is WITH, run command RZ005 Programming to reinitialise the vehicle
configurations.
– Clear the faults.
– 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 sensor is correctly connected:
– Bleed the diesel filter unit (see MR 395 (Laguna II), 370 (Scénic II) or 364 (Mégane II), Mechanical, 13A, Fuel
supply).
– 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 the fault finding procedure.
d)If the fault reappears:
– Check the continuity and absence of interference resistance on connection 3WT between components 414
and 120.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Check the supply of the water detection sensor between connections 3FB and N.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, 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 395 (Laguna II), 370 (Scénic II) or 364 (Mégane II), Mechanical,
13A, Fuel supply).
– 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:
If the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (turns, hills)
may cause erratic illumination of the injection fault warning light.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
This fault only occurs on vehicles with automatic transmission.
Check the oil temperature sensor connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the oil temperature sensor between connections 47Q and 115A.
Replace the oil temperature sensor if the resistance is not approximately:
11 50 Ω at 40°C
308 Ω at 80°C
105 Ω at 120°C
53 Ω at 150°C
Check the insulation, continuity and the absence of interference resistance of the following connections:
– connection code 47Q,
– connection code 115 A.
Between components 120 and 688.
If the connection or connections are faulty and 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 is still present, replace the oil temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

the corresponding injector.
Enter the code to the unprogrammed/incorrectly programmed injector, if necessary.
Refer to the interpretation of command SC002 Enter injector codes (see Interpretation of commands).
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
When dealing with a number of misfiring faults, check the fuel conformity by running test 11 Diesel fuel
conformity check.
Visually inspect the return pipe of injector no. 1.
Repair if necessary.
If the fault is still present, run test 9 Poor injector operation.

STOREDIMPACT DETECTED SIGNAL
1.DEF: Impact stored by the injection computer
NOTESConditions for applying the fault finding procedure to stored faults:
Only apply the interpretation of this fault if the fault is present and the vehicle will not
start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from
the Airbag computer via the multiplex network.
As soon as the injection computer receives this signal:
– engine operation is prohibited,
– the level 2 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs,
– clear the fault,
– switch off the ignition,
–wait 1 minute,
– switch on the ignition.
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, run fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident:
Run fault finding on the AIRBAG computer (see 88C, Airbag and pretensioner).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
