ABSENT ignition on
Check the condition and conformity of the F5D (5A) supply fuse for the UPC.
Repair if necessary.
Check for the presence of an earth on the following connections:
Injection computer black 32-track connector A, track G4 battery earth
Injection computer black 32-track connector A, track H4 battery earth
Injection computer black 32-track connector A, track H1 battery earth
Repair if necessary.
Check for + 12 V on trackD1 of connector A of the injection computer.
If there is no voltage, check the continuity and insulation against earth of the following
connection:
Injection computer black 32-track connector A, track D1 Track 1 UPC black
connector
Repair if necessary.
PRESENT ignition on
Check that there is not + 12 V with the ignition switched on trackD1 of connector A of
the injection computer.
Repair if necessary.

PRE-POSTHEATING UNIT CONTROL
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
When the vehicle is started from cold, the injection computer controls the pre/postheating
unit so that the vehicle can be started.
Status ET007 changes to YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 changes to YES, check:
–the F2 (70A) supply fuse on the preheating unit,
– the resistance of the heater plugs.
Replace any plugs with a resistance greater than 2 Ω.
If the vehicle starts and the status ET007 remains YES during the engine functional
stage, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
After the engine is started and preheating, the injection computer should stop the pre/
postheating unit operating.
Status ET007 Should change to NO.
In the event that the vehicle does not start and status ET007 remains at NO, check the
continuity and the absence of interference resistance of the following connections:
Injection computer grey 32-track connector C, track A4 Track 9 preheating
unit
Injection computer grey 32-track connector C, track E2 Track 8 preheating
unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

ET042
(CONTINUED 1)
INACTIVE
When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main button being in the
rest position (or neutral), carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
– Connection code AP43 of component 1081 (Mégane II)
– Connection code AP43 of component 1546 (Scénic II)
Disconnect the main switch and with it in the rest position, check the insulation between:
– Connection codes AP43 and 3FX of component 1081 (Mégane II)
– Connection codes AP43 and 3PD of component 1081 (Mégane II)
– Connection codes AP43 and 3FX of component 1546 (Scénic II)
– Connection codes AP43 and 3PD of component 1546 (Scénic II)
Check the continuity between connections AP43 and 3PD of component 1081
(Mégane II) and component 1546 (Scénic II) in the speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) and component 1546 (Scénic II) in the cruise control position.
If these checks are not in order, replace the switch.
Check the insulation, continuity and the absence of interference resistance on the
following connections:
– Connection code 3FX,
– Connection code3PD.
Between components 1081 and 120 (Mégane II)
Between components 1546 and 120 (Scénic II)
Also check the engine management computer connectors.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
