•3JAA between components 120 and 1068 or 1550,
•3JAB between components 120 and 1069 or 1550.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the + 12 V after relay supply to the thermoplunger 1, thermoplunger 2, thermoplunger 3 relay mounting of
the following connections:
•3FB of component 1067 or 1550,
•BP91 of component 1068 or 1550,
•BP9 of component 1069 or 1550.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Actuate the various thermoplunger relays one by one using commands:
– AC063 Thermoplunger no. 1 relay
– AC064 Thermoplunger no. 2 relay
– AC031 Thermoplunger no. 3 relay
Check the voltage using a multimeter. If the voltage is zero, the thermoplunger is faulty.
Only replace the faulty thermoplunger.

If the ignition is not switched on, status ET001 should be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. Status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
– Check the condition of fuse FM3 (30A) in the engine fuse and relay box (see MR 395 (Laguna II ph2), 405
(Espace IV ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).
– Check the condition of fuse F18 (15A) in the Protection and Switching Unit (UPC) (see MR364 (Mégane II ph2),
MR370 (Scénic II ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).
Check the continuity and absence of interference resistance on the following connection:
•3AA between components 120 and 983 or 1337.
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.
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, contact the Techline.

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.

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

YES
When the driver depresses the clutch pedal, status ET034 becomes YES until
the ignition is next switched off.
If NO appears despite the clutch pedal being depressed, carry out the following
operations:
– Remove the clutch pedal switch, check the insulation between connections M
and86D of component 675, with the switch in the rest position.
– Repeat this operation with the switch engaged and check the continuity
between the two connections.
If these 2 checks are faulty, replace the switch.
Check the condition of the clutch switch connector (see Wiring Diagram Technical
Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2,
component code 675).
Check the condition of the engine management computer connector (see Wiring
Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II
ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure
(seeTechnical Note 6015A, Repairing electrical wiring, Wiring: Precautions
for repair), repair the connector, otherwise replace the wiring.
Then check the continuity and absence of interference resistance of the
connection:
•86D between components 120 and 675.
– Check for complete earthing on connectionM of component675.
If the connection or connections are faulty and there is a repair procedure (see

ET042 Cruise control/speed limiter is permanently NOT DETECTED. Confirmation
of the absence of the cruise control or speed limiter function on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons and the main
switch is in the rest (or neutral) position and after the injection computer has been
programmed or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the
cruise control position and then in the speed limiter position.
Return to rest position
The tool displays status ET042: INACTIVE.
If not, several steps must be checked:
1. Return to the multiplex network test page on the Clip application. Repeat the
multiplex network test. Re-establish dialogue with the injection computer.
CheckET042. If ET042 is INACTIVE, the injection computer has detected the
various positions of the main switch. The cruise control/speed limiter is active.
2. If ET042 is still NOT DETECTED, check that the owner of the vehicle has not
had the cruise control/speed limiter function deactivated in the past. Contact
the Techline.
