DEFINITIONPRESENT: This status indicates that the pre-postheating signal is still active.
ABSENT: This status indicates that the pre-postheating signal is not active.
NOTESTest the battery and run fault finding on the charging circuit (see Technical Note
6014A, Checking the charging circuit).
Conformity check with engine stopped and ignition on, or engine running, and engine coolant

"PRESENT"Status ET120 is PRESENT when preheating is activated.
Refer to the interpretation of fault DF025 Preheating unit diagnostic line, if status
ET120 remains ABSENT.
"ABSENT"Status ET120 is ABSENT when the pre-postheating is not activated.
Consult the interpretation of faults DF025 Preheating unit diagnostic line and DF017
Preheating unit control circuit if status ET120 is PRESENT instead of ABSENT.

Thermoplungers
There must be no present or stored faults:
Perform this fault finding procedure if there is a fault with the passenger compartment
heating - demisting.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
If the Thermoplunger no. 3 relay or the additional heater interface unit does not function when command
AC031 is run.
Check the condition of the thermoplunger 3 relay mounting on the engine fuse box or the additional heater
interface unit (see Wiring Diagram Technical Note, Vehicle, component code 1069 or 1550).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Vehicle, component code 120).
If the connector or connectors are faulty and if 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 fault is still present, check as follows that this relay is controlled by the engine management computer:
Disconnect the thermoplunger no. 3 relay and fit a 50 Ω to 100Ω resistor on its mounting instead of the coil and
connect a voltmeter as follows:
– positive terminal to + 12 V battery,
– negative terminal to connection 3JAB of component 1069 or 1550.
Run command AC031.
If the voltmeter indicates the battery voltage (4 ON-OFF cycles of 10 seconds), replace the thermoplunger no. 3
relay.
If the voltmeter does not show the battery voltage (4 ON-OFF cycles of 10 seconds), contact the Techline.

If the thermoplunger no. 3 relay or the additional heater interface unit functions using command AC031,
but there is still a passenger compartment heating/demisting problem, use the wiring diagram to check:
– The conformity of the thermoplungers maxi-fuse.
– Check for + 12 V battery feed on connection BP9 of component 1069 or 1550.
– Check the conformity of heating element no. 3 relay.
– Check the continuity of connection 3JAC or 3JC between components 1069 or 1550 and 1074.
– Measure the resistance of the thermoplunger*.
– The presence of earth on the water chamber (thermoplunger mounting).
– Also check the level of the cooling circuit and that there are no leaks.
Carry out the necessary repairs.

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.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
IMPORTANT:
– Please observe the cleanliness guidelines and safety advice.
– Make sure the correct type of plug is fitted on the vehicle, slow or fast:
Slow plugs have a black ring
Quick plugs have a white ring.
For Vdiag 20, 24, 34, 38 and 74, if replacing heater plugs by plugs of a different type
(see Replacement of components and Replacing heater plugs).
Before applying the following fault finding procedure, check that the battery voltage is not below 12 V. Otherwise,
recharge the battery.
STEP 1:
Using a multimeter fitted with a current clamp, bring together the 4 heater plug supply wires.
Run command AC037 and measure the current consumed by the 4 heater plugs.
If the value of the current consumed is not between 60 A and 80 A, move on to step 2, otherwise end of fault
finding.

•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.
Check the condition of the preheating unit supply fuse (70 A) (see MR 364 (Mégane II ph2), MR 370 (Scénic II
ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 81C, Fuses, Fuses: List
and location of components).
Check the + 12 V battery supply to the preheating unit on the following connection:
•BP35 of component 257.
Check the continuity and absence of interference resistance of the following connections:
•3FY between components120 and 257,
•3FF between components120 and 257.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
