1.DEFSpecial note:
This fault appears when the computer control section has
overheated.
Check the conformity of fuses F2 (70A) and F3 (70A) on component 777, replace if necessary.
Check the connections on the additional heater interface unit.
check the engine management computer connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Check for + 12 V after ignition feed on connections BP27 and BP35 of component 1550.
If there is no + 12 V, refer to the interpretation of fault DF151 Main relay circuit.
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 it.

Check the supply to thermoplunger 4:
– Disconnect the connector of component 1074.
– Connect a test light between connection 3JAC of component 1074 and a chassis earth.
– Run command AC031 Thermoplunger relay no.3.
If the test light illuminates correctly, measure the resistance of the thermoplunger 4 between the following
connection:
–3JAC of component 1074 and a chassis earth,
If the resistance is greater than 2Ω, replace thermoplunger 4.
If the test light does not come on, check the continuity and insulation of the following connection:
– Connection code 3JAC between components 1550 and 1074.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the earthing on the additional heater interface unit:
– Disconnect the connector of component 1550.
– Connect a test light between connections 3JAB and BP27 of component 1550.
– Run command AC031 Thermoplunger relay no.3.
If the test light comes on correctly, replace the additional heater interface unit.
If the test light does not come on, check the continuity and insulation from + 12 V of the following connection:
– Connection code 3JAB between components 120 and 1550.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

Fault finding – Interpretation of statuses13B
ET007PRE-POSTHEATING UNIT CONTROL
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.

AC037PREHEATING RELAY
NOTESThis command is only run if fault DF025 Preheating unit diagnostic connection or
DF017 Preheating unit control circuit is present or stored and if no other fault is
present.
Ignition on and engine stopped.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Before applying the following fault finding procedure, check that the battery voltage is not below 12 V.
Otherwise, recharge the battery.
Check the connections on the preheating unit, heater plugs and injection computer.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Measure the resistance of the heater plugs. If this resistance is > 2 Ω, replace the defective plug(s).
Check the continuity and the absence of interference resistance on the following connections:
– Connection code 37AA between components257 and 681.
– Connection code 37AB between components 257 and 682.
– Connection code 37AC between components 257 and 683.
– Connection code 37AZ between components 257 and 680.
Check the condition of fuse FM12 (70 A) of the preheating unit supply. Replace it if necessary.
Then check for +12 V on connection BP35 of component 257.
Check the continuity, insulation, and the absence of interference resistance of the following connections:
– Connection code 3FF,
– Connection code 3FY,
Between components 257 and 120.
If the fault is still present, replace the pre-postheating unit.

Fault finding – Interpretation of commands13B
VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.
