1.DEF: Internal electronic fault
2.DEF: Inconsistent signal
NOTESPriorities when dealing with a number of faults:
– DF046 Battery voltage.
Conditions for applying the fault finding procedure to a stored fault:
If the fault is declared present after:
– starting the engine,
– a road test.
Special notes:
Computer operating voltage: 6 V < operating voltage < 16.5 V.
Use bornier Elé.1681 for any operations on the injection computer connectors.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Check the condition of the alternator connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel Satis
ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 103).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the ignition is switched on.
– the engine is started,
– a road test,
– if the air flowmeter temperature > 5°C.
Priorities when dealing with a number of faults:
– DF209 EGR valve position sensor circuit,
– DF046 Battery voltage,
– DF012 Sensor supply voltage no. 2,
– DF272 EGR valve control circuit.
Special notes:
–the level 1 and EOBD (European On Board Diagnostic) warning lights are lit for
1.DEF, 2.DEF, and 4.DEF
– only the EOBD (European On Board Diagnostic) warning light is lit for 3.DEF,
– the EGR function is inhibited by the engine management computer,
– reduced performance for 2.DEF and 3.DEF or 1.DEF and 2.DEF (for Vdiags 5C, 58
and 24, and 20, 26, 28, 60, 62).
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
