STOREDTHERMOPLUNGER 2 RELAY CONTROL CIRCUIT
CC.1: Short circuit to + 12 V
1.DEF: Internal electronic fault
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– the ignition is switched on,
– with the engine running,
– actuator command AC064 Thermoplunger no. 2 relay.
Special notes:
Use bornier Elé. 1681 for all operations on the connectors of the engine management
computer.
Use the Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
CC.1
NOTESNone.
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.

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

Check the supply to thermoplungers 2 and 3:
– Disconnect the connector of component 1072.
– Connect a test light between connection 3JC of component 1072 and a chassis earth.
– Run command AC064 Thermoplunger no. 2 relay.
– Disconnect the connector of component 1073.
– Connect a test light between connection 3JD of component 1073 and a chassis earth.
– Run command AC064 Thermoplunger no. 2 relay.
If the test light comes on correctly, measure the resistance of thermoplunger 2 and 3 between the following
connections:
–3JC of component 1072 and a chassis earth,
–3JD of component 1073 and a chassis earth.
If the resistance is greater than 2 Ω, replace thermoplunger 2 or 3.
If the test light does not come on, check the continuity and insulation of the following connections:
– Connection code 3JC between components 1550 and 1072.
– Connection code 3JD between components 1550 and 1073.
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 earthing on the additional heater interface unit:
– Disconnect the connector of component 1550.
– Connect a test light between connections 3JAA and BP27 of component 1550.
– Run command AC064 Thermoplunger no. 2 relay.
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 3JAA 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.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

STATUS DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.
INACTIVE: This status indicates that the thermoplunger is not supplied.
NOTESStatus only available on certain Vdiag48 (depending on vehicle equipment).
INACTIVEStatuses ET205, ET206, ET207 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
ACTIVEStatuses ET205, ET206 and ET207 are ACTIVE when the engine is started, the
engine coolant temperature is low (< 15°C) and the air temperature is low (< 5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
The thermoplungers also act both to load the engine to improve regeneration of the
particle filter
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 1 relay control circuit.
DF033 Thermoplunger 2 relay control circuit.
DF034 "Heating element 3 relay control circuit".

PR045POWER REQUESTED BY THERMOPLUNGERS
PARAMETER
DEFINITIONThis parameter indicates the power consumed by the thermoplungers in watts.
NOTESSpecial note:
Only perform these tests if the parameters do not correspond with the system
operation programming.
This parameter exists on certain vehicles in Vdiag 48 (depending on equipment).
Engine running, engine coolant temperature > 80°C, with no electrical consumers
0 If the parameter value is not within this range, consult the interpretation of faults:
– DF032 Thermoplunger 1 relay control circuit,
– DF033 Thermoplunger 2 relay control circuit,
– DF034 Thermoplunger 3 relay control circuit.
Engine stopped, ignition on
PR045=0W
In the event of a fault, consult the interpretation of faults:
– DF032 Thermoplunger 1 relay control circuit,
– DF033 Thermoplunger 2 relay control circuit,
– DF034 Thermoplunger 3 relay control circuit.
