NOTESSpecial note:
Risk of starting difficulty due to absence of preheating.
Check the condition of the preheating unit connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 257).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector(s) is/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.
Check the continuity of the following connections:
– Connection code 3FY between components 120 and 257.
– Connection code 3FF between components 120 and 257.
Check for + 12 V battery on the preheating unit connector.
– Connection code 3FY of component 257.
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 is still present, replace the pre-postheating unit.

computer
NOTESPriorities when dealing with a number of faults:
Deal with fault DF017 Preheating control circuit first, if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– when the ignition is switched on, during the preheating phase,
– engine running in postheating phase,
– controlling the heater plugs using command AC037 Preheating relay.
Special notes:
If the fault is present:
Use bornier Elé. 1681 for all operations on the connectors of the engine management
computer.
–The European On Board Diagnostic injection warning light is lit.
– Difficult to start the engine.
– Refer to the Wiring Diagram Technical Notes for the vehicle to locate the fuses and
relays concerned.
IMPORTANT
Please observe the cleanliness guidelines and safety advice.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
