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.

STATUS DEFINITIONACTIVE: when the heater plugs are activated according to the temperature of the
engine coolant.
INACTIVE: after the engine has been running for a certain period.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Use the Mégane II ph2, Scénic II ph2 Technical Note wiring diagram.
Conformity check with engine stopped and ignition on
ACTIVEWhen the ignition is switched on, the status ET007 must have an ACTIVE status for a
time that varies depending on the temperature of the engine coolant. Both the relay
and the heater plugs are supplied.
After starting, the status should remain ACTIVE for a time that varies depending on
the engine temperature. This is the postheating phase.
If ET007 is INACTIVE when the ignition is switched on, check:
– The supply fuse FM12 (70A) in (597) the engine fuse and relay box.
– The feed to the heater plugs after relay actuation, and the connections of the heater
plugs.
IMPORTANT
On this engine, the plug supply voltage is variable.

CONTINUED
Sensor electrical conformity
ACTIVEWhen the coolant reaches 99°C, the injection computer commands the low-speed
relay of the fan assembly, and status ET143 becomes ACTIVE. The relay then
supplies the fan assembly and the cooling fan begins to turn.
If status ET143 is ACTIVE, but the cooling fan is not running, perform the following
operations:
– Check the condition of fuse FM15 (60 A) in the engine fuse and relay box.
Disconnect the low speed and high speed relays, check their operation and the status
of the connectors of the relay mounting (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Component code 597).
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.
Check for the supply of + 12 V after the relay to the low-speed relay of the fan
assembly:
– Connection 3FB of component 700.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49L between components 700 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 262 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 3JN between components 700 and 120.
Check that the earth is in order on the MAS connection of component 262.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring. Otherwise replace the wiring.
INACTIVEIf the engine temperature is lower than 99°C, the engine cooling fan cannot switch on
and the low speed fan relay of the cannot be run.
Status ET143 must therefore be INACTIVE when the control relay and the engine
cooling fan are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Conformity check with engine running, engine coolant temperature > 80°C
(heating and air-conditioning off) INACTIVE OR ACTIVE, depending on the engine temperature.
ACTIVEWhen the coolant reaches 102°C, the injection computer commands the low-speed
relay of the fan assembly and status ET144 becomes ACTIVE. The relay then
supplies the cooling fan.
If status ET144 is ACTIVE, but the cooling fan is not running, perform the following
operations:
– Check the condition of fuse FM15 (60 A) in the engine fuse and relay box.
– Disconnect the high speed relay of the fan assembly, check it is functioning correctly
and the status of the connectors of the relay mounting (see Wiring Diagram
Technical Note, Mégane II ph2, Scénic II ph2, Component code 597).
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.
Check for the supply of + 12 V after the relay to the high-speed fan assembly relay:
– connection 3FB of component 234.
Check the continuity and the absence of interference resistance on the following
connection:
– connection code 3JP between components 234 and 120.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 234 and 262.
Check that the earth is in order on the MAS connection of component 262.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring. Otherwise replace the wiring.
INACTIVEWhen the injection computer no longer requests cooling, the status ET144 changes to
INACTIVE. The fan assembly should then switch off.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
