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

IMPORTANT:
Clear the fault memory by running command RZ001 "Fault memory" to reset this status to "NONE".
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
STATUS 1:Traction control request.
STATUS 2:Brake pedal depressed.

STATUS 2
Brake pedal depressed
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) and brake pedal depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 2 without depressing the brake pedal, consult
the interpretation of statuses ET704 Brake contact no. 1 and ET705 Brake
contact 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 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).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

If status ET415 changes to STATUS 5, deal with present faults or those stored in
the injection computer.
If the fault is still present, contact the Techline.
STATUS 6Gear lever in neutral (manual gearbox) or neutral (automatic gearbox)
Status ET415 changes to STATUS 6, when driving, with cruise control active (ET042:
CRUISE CONTROL) and:
– if the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is put in neutral on an automatic transmission.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on
a manual gearbox without declutching, or into the neutral position on an automatic
transmission, run fault finding on the ABS computer and check the configuration of the
tyre size stored in the computer. If the configuration is correct, contact the Techline.

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).
