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.

following connections:
– Connection code 3FX,
– Connection code 3PD,
between components 1081 and 120 (Mégane II).
between components 1546 and 120 (Scénic II).
Also check the engine management computer connectors.

IMPACT DETECTED
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
If the vehicle has been involved in an accident, the injection computer receives the
impact signal via the multiplex network and may switch off the ignition. Status ET077 is
at YES.
Switch off the ignition for ten seconds, then switch it back on to enable the engine to start.
Carry out a multiplex network test and deal with any faults.
Clear the injection computer faults, even if no fault is present.
In normal operating conditions, status ET077 is NO when the computer has received no
impact signal.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

SYNCHRONISATION
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
WARNING
Synchronisation is carried out during the engine starting phase. This is established between the camshaft
position sensor and the TDC sensor.
Once this synchronisation has been carried out, it enables the computer to identify cylinder no.1 and to
ascertain the precise position of the cylinder's top dead centre.
INACTIVE
COMPLETED
When the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is INACTIVE, no synchronisation between the crankshaft and the
camshaft is performed.
Synchronisation is carried out during the engine starting phase.
Cylinder No. 1 is indicated and synchronisation will be performed once the engine is
started.
Status ET238 is "COMPLETED".
If after several attempts to start the engine status ET238 remains INACTIVE, refer to the
interpretation of the following faults:
–DF005 Engine speed sensor circuit
–DF097 Camshaft sensor circuit
If the engine still does not start, (see Customer complaints, ALP2 Starting faults).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various factors that cause deactivation of the cruise control/speed limiter function, due to a
driver request or the external environment (e.g. STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ001 Fault memory to reset this status to NONE.
WITHOUTThis status is present on the diagnostic tool when:
The computer has been reinitialised.
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).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2, when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and the brake pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 2 with no application of the brake pedal, consult the
interpretation of statuses ET704 and ET705 Brake contact no. 1 and no. 2.
STATUS 3Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with the cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405 Clutch pedal switch.
If the vehicle is fitted with automatic transmission:
Carry out a multiplex network test, check the configuration of the multiplex network
according to the vehicle's technical specifications and, in particular, the automatic
gearbox computer configuration (see 88B, multiplex).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
