NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault is declared present after:
– when an attempt is made to start the engine,
– starting the engine,
– a road test.
Special notes:
The engine speed sensor is consistent with the camshaft sensor.
If the fault is present,
–the level 2 warning light will be lit,
– engine stops or impossible to start,
– engine cut-off,

Use bornier Elé.1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Check the condition of the engine speed sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 149).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the sensor is securely attached.
Measure the resistance of the engine speed sensor between the following connections:
– Connection code 3BG of component 149.
– Connection code 3BL of component 149.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the winding resistance is not between 200 Ω and 270 Ω at 20°C, replace the engine speed sensor.

STATUS 3
Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is no longer 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 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 an 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).
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button
is pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either the cruise control is active, or
– the speed limiter is active
– and when the "0" button is pressed by the driver.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault-
finding on the R/0 control button located on the steering wheel, to the right.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

buttons are pressed. These buttons are located on the steering wheel.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's frontal airbag (see MR 364 Mégane,
MR370 Scénic, Mechanical, 88C, Airbag and pretensioners, Driver's front
airbag, Removal - Refitting).
If status ET703 does not display INACTIVE,
– check the status of the cruise control/speed limiter +/- button and the condition of its
connector.
– check the status of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes INCREASE when the + button of the cruise control/speed
limiter is pressed. This button is on the steering wheel, on the left-hand side.
To carry out these checks and measurements in complete safety, observe the

airbag, Removal - Refitting)
If status ET703 does not display INCREASE, check the status of the +/- button of the
cruise control/speed limiter and the status of its connector. Repair if necessary.
Measure the resistance on the following connections while pressing the +
button (on the button tracks):
– Connection code 86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the +/- control button.
