The fault is declared present during an After-Sales regeneration, if the temperature
threshold is exceeded.
Special notes:
If the fault is present:
– regeneration in progress is stopped.
IMPORTANT: The fault appears if the temperature threshold is exceeded during
the After-Sales regeneration phase.

ET007PRE-POSTHEATING UNIT CONTROL
STATUS
DEFINITIONACTIVE: when the heater plugs are activated according to the engine coolant
temperature.
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:
This status is specific to slow heater plugs (black ring).
Conformity check with engine stopped and ignition on.
"ACTIVE"When the ignition is switched on, status ET007 should be ACTIVE for a time that varies
according to the engine coolant temperature. Both the relay and the heater plugs are
supplied.
After starting, the status should remain ACTIVE for a time that varies according
to the engine temperature. This is the postheating phase.
If ET007 is INACTIVE when the ignition is switched on, check:
– Supply fuse FM12 (70A) of component 597 (engine fuse and relay box) or F2 (70A)
of component 777 for Mégane II and Scénic II
–The supply to the heater plugs after relay actuation, and the connections of the
heater plugs.
Important: on this engine, the plug supply voltage is variable.
– Check the continuity and absence of interference resistance of the following
connections:
•37AB between components 257 and 683,
•37AA between components 257 and 680,
•37Z between components 257 and 681,
•37AC between components 257 and 682.
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.

Scénic II ph2, component code 257).
If the connector or connectors are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the connector, otherwise replace the wiring.
If the vehicle starts, postheating has ended and status ET007 remains ACTIVE
during the engine operating phase, refer to the interpretation of faults DF017
Preheating unit control circuit and DF025 Preheating unit diagnostic
connection.
"INACTIVE"If the vehicle does not start, the status remains INACTIVE and preheating does not
start when the ignition is switched on or during the starting phase.
Check the continuity and absence of interference resistance on the following
connections:
•3FY and 3FF between components 120 and 257.
Check the + 12 V battery supply to the preheating unit on the following connection:
•BP35 of component 257.
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.

STATUS
DEFINITIONACTIVE: These statuses indicate that the thermoplungers are active.
INACTIVE: These statuses indicate that the thermoplungers are inactive.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"INACTIVE"Statuses ET024, ET025, and ET026 are INACTIVE when the ignition is switched on
with the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET024, ET025, and ET026 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°C),
– and the air temperature is low (< 5°C).
This strategy allows the engine coolant to be heated and to allow the heating of the
passenger compartment.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no. 1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no. 3 relay.
In the event of a fault, refer to the interpretation of faults:
– DF032 Thermoplunger no. 1 relay control circuit,
– DF033 Thermoplunger no. 2 relay control circuit,
– DF034 Thermoplunger no. 3 relay control circuit.
