"ACTIVE"
– Check the connection and condition of the preheating unit (see Wiring Diagram
Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2,
Scénic II ph2, component code 257).
If the connector or connectors are 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.
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
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
Conformity check with the engine running and engine coolant temperature > 80°C
"ACTIVE"
then
"INACTIVE"After the engine has been running for a certain period, the status changes from
ACTIVE to INACTIVE.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit
control circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS
DEFINITIONACTIVE: These statuses indicate that the thermoplungers are active.
INACTIVE: These statuses indicate that the thermoplungers are inactive.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"INACTIVE"Statuses ET024, ET025, and ET026 are INACTIVE when the ignition is switched on
with the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET024, ET025, and ET026 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°C),
– and the air temperature is low (< 5°C).
This strategy allows the engine coolant to be heated and to allow the heating of the
passenger compartment.
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 no. 1 relay control circuit,
– DF033 Thermoplunger no. 2 relay control circuit,
– DF034 Thermoplunger no. 3 relay control circuit.

CONTINUED
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
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.

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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
