INACTIVE or ACTIVE, depending on the engine temperature (air conditioning switched off).
In the event of a fault, refer to the interpretation of fault DF018.
Sensor electrical conformity
"ACTIVE"When the coolant reaches 99°C, the injection computer actuates the low-speed fan
assembly relay, 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 (see MR364
(Mégane II ph2), MR370 (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).
Disconnect the low speed and high speed relays, check that they are operating
correctly and check the condition of the relay mounting connectors (see Wiring
Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II
ph2, Scénic II ph2, component code 597).
If one of the connectors is 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.
Check the + 12 V after relay supply to the low speed fan assembly relay on the
following connection:
•3FB of component 700.
Check the continuity and absence of interference resistance of the following
connections:
•49L between components 700 and 321,

NOTESThere must be no present or stored faults.
Perform this fault finding procedure if there is a fault with the passenger compartment
heating - demisting.
Consult the "Wiring diagrams" Technical Note to locate the relevant fuses and relays.
Special notes:
The thermoplunger no. 2 relay or the additional heater interface unit supplies
thermoplungers 2 and 3 in parallel.
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. 2 relay does not operate during command AC064.
Check the condition of the thermoplunger 2 relay mounting on the engine fuse box or the additional heater
interface unit (see Wiring Diagram Technical Note, Vehicle, component code 1068 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, Repairing
electrical wiring, 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. 2 relay, fit a 50 Ω to 100 Ω resistor on its mounting instead of the coil, and
connect a voltmeter as follows:
– positive terminal to + 12 V battery,
– negative terminal on connection 3JAA of component 1068 or 1550.
Run command AC064.
If the voltmeter shows the battery voltage (4 ON-OFF cycles of 10 seconds), replace the thermoplunger no. 2
relay.
If the voltmeter does not show the battery voltage (4 ON-OFF cycles of 10 seconds), contact the Techline.
