SPEED LIMITERWhen the driver presses the main switch in the speed limiter position, status ET042
becomes SPEED LIMITER.
If CRUISE CONTROL or INACTIVE appears although the switch was pressed in the
speed limiter position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V after ignition feed 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 code AP43 and 3FX, of component 1081 (Mégane II).

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.
If there is a repair method (See Technical Note 6015A, Repairing electrical wiring,

IMPACT DETECTED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
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
YES.
Switch off the ignition for 1 minute then switch on the ignition again so the engine can be
started.
Carry out a multiplex network test and deal with any faults.
Under normal operating conditions, status ET077 is NO when the computer has received
no impact signal.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

PASSENGER COMPARTMENT HEATING RESISTOR CUT-OFF
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer cuts off the passenger compartment heating
resistors.
Status ET112 becomes YES when the passenger compartment heating resistors are cut
off by the injection computer.
Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer cuts off the passenger compartment heating
resistors.
Status ET112 becomes NO when the passenger compartment heating resistors can be
freely controlled by the UCH.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

SYNCHRONISATION
NOTESSpecial notes:
Only perform these 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 calculate
the precise position of the cylinder's Top Dead Centre.
NOT PERFORMED
When the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is NOT DONE; synchronisation between the crankshaft and the camshaft
has not been carried out.
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 DONE.
If after several attempts to start the engine, status ET238 remains NOT DONE, refer to
the interpretation of the following faults:
–DF005 Engine speed sensor circuit.
–DF097 Camshaft sensor circuit.
If the engine does still not start, consult the Customer complaints section, ALP2
Starting faults.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial note:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various things 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 RZ007 Fault memory, to reset this status to WITHOUT.
NONE
This status is present on the diagnostic tool when:
The computer has been reinitialised,
The computer has been reprogrammed.
Traction 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 cruise control active (ET042:
Cruise control/Speed limiter: CRUISE CONTROL) and upon a traction control
request.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 1 without a traction control request (see 38C, ABS).
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with 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 RZ007
“Fault memory”.
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult the
interpretation of statuses ET704 and ET705 Brake contact No. 1 and No. 2.
Clutch 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 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 RZ007
“Fault memory”.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405: Clutch pedal.
If the vehicle is fitted with automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation to
the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing)
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
