STATUS
DEFINITIONACTIVE: this status indicates that the clutch pedal is depressed.
INACTIVE: this status indicates that the clutch pedal is released.
NOTESCan only be displayed for manual gearboxes.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"ACTIVE"Clutch pedal depressed.
Non-conformity of the brake signals and/or the clutch switch signals can cause
the engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.

Non-conformity of the brake signals and/or the clutch switch signals can cause
the engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.

CONTINUED 3
STATUS 4
Cancel button pressed
The cruise control/speed limiter function is deactivated each time 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 right-hand side of the steering wheel.
STATUS 5Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, consult the interpretation:
- of status ET042 Cruise control / speed limiter,
- of status ET703 Cruise control / speed limiter buttons,
- of status ET704 Brake switch no. 1,
- of status ET705 Brake switch no. 2,
to test the cruise control/speed limiter system components and find the defective
component.
In addition, check the operation of the accelerator pedal, and use the diagnostic tool
to check for any faults associated with the accelerator pedal. Deal with them if
necessary.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Perform the following road test (looking for a loss of power when accelerating under full load):
– in the highest gear ratio, accelerate fully,
– lift your foot off the accelerator pedal completely for at least 2 seconds,
– accelerate fully again,
– release the accelerator pedal completely,
– accelerate slightly.
If the loss of power was not noted during slight acceleration and if there was a loss of engine power during each
acceleration at full load, replace the diesel fuel injector return rail and its overpressure valve (see MR364
(Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2)
Mechanical, 13B, Diesel injection, Diesel injector fuel return rail: Removal - Refitting).
Check the connection and positioning of the differential pressure sensor (see MR 395 (Laguna II ph2), 402 (Vel
Satis Ph2), 405 (Espace IV ph2), 364 (Mégane II ph2), 370 (Scénic II ph2) Mechanical, 19B, Exhaust, Particle
filter pressure sensor: Removal - Refitting).
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
parameters).
Check the consistency of the signal from the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed sensor.
Check the connections, the continuity and the absence of interference resistance of the following components:
– the air flowmeter (apply DF056 Air flow sensor circuit)
– the engine coolant temperature sensor (apply DF001 Coolant temperature sensor circuit)
– the fuel temperature sensor (apply DF098 Fuel temperature sensor circuit)
– the engine speed sensor (apply DF195 Engine speed/camshaft sensor consistency).

NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
If the engine races during gear changes, if there is a floor mat, check that this is not blocking the accelerator pedal,
the brake pedal and the clutch pedal, then check the conformity of the clutch switch and the conformity of the
accelerator pedal sensor when the pedal is released (see PR086 Pedal potentiometer voltage gang 1 and
PR088 Pedal potentiometer voltage gang 2, Sensor supply).
Measure the resistance between connections 3BG and 3BL of component 149.
If the sensor resistance is not between:
741 Ω < X < 905 Ω at +20°C, replace the sensor.
Check the continuity and absence of interference resistance on the following connections:
•3BG between the components 120 and 149,
•3BL between components 120 and 149.
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.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting and condition (overheating) of the sensor.
Check the low pressure circuit: run Test 3 Low pressure circuit check.
Apply the air flow checking procedure, (see conformity in the interpretation of statuses and parameters).
Check the turbocharger: apply Test 7 Variable geometry turbocharger control.
If the fault is still present, test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding.
To interpret the result, apply the interpretation of command SC035 (see Interpretation of commands).
