ET120PRE-POSTHEATING SIGNAL
STATUS
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
temperature > 80°C
"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.

ET143

Conformity check with the engine running and engine coolant temperature > 80°C
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,
•49B between components 262 and 321,
•3JN between components 700 and 120.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Sensor electrical conformity
"ACTIVE"When the coolant reaches 102°C, the injection computer actuates the fan assembly
relay and status ET144 becomes ACTIVE. The relay then supplies the cooling fan.
If status ET144 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

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 high-speed fan assembly relay on the
following connection:
•3FB of component 234.
Check the continuity and absence of interference resistance of the following
connections:
•3JP between components 234 and 120,
•49B between components 234 and 262.
Check that the earth is in order on connection MAS of component 262.
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 REPAIRCarry out a road test, then check with the diagnostic tool.

temperature > 80°C
PRESENTThere is a multiplex connection between the injection computer and the automatic
transmission computer.
ABSENTThere is no multiplex connection between the injection computer and the automatic
transmission computer, as there is a manual gearbox.
If there is an automatic transmission and the message ABSENT appears:
Run a multiplex network test (see 88B, Multiplex).
Check the continuity and insulation to earth of the following connections:
•3MS and 3MT between components 119 and 120.

The computer has been reprogrammed.
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active
(ET042 Cruise control / speed limiter: CRUISE CONTROL) and traction control is
requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-
lock braking system).
