STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4, when driving if:
–either the cruise control is active or
–the speed limiter is active,
–and the driver presses the 0 button.
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 indicating 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,
–and status ET705 Brake switch no. 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 5, deal with the present or stored faults in the injection
computer.
If the fault is still present, contact the Techline.

STATUS DEFINITIONACTIVE: This status indicates that the brake pedal is depressed.
INACTIVE: This status indicates that the brake pedal is released.
Note:
Statuses ET704 and ET705 should change status at the same time. In the event of inconsistency, refer to the
interpretation of fault DF050 Brake switch circuit.
Conformity check: Engine stopped, ignition on or engine running.
ACTIVE
OR
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
–5A between components 160 and 120,
–BPT between components 160 and 645 (for Mégane II, Scénic II, Modus and Clio III),
–BPT2 between components 160 and 645 (for Kangoo 2),
–AP10 between components 160 and 1016 (for New Twingo),
–65A between components 160 and 645 (vehicle without ESP),
–65G between components 160 and 645 (vehicle with ESP).
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 brake lights are not operational, check:
–the condition and fitting of the brake switch,
–the condition and conformity of the brake lights fuse,
the conformity of the values in the following table:

In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
–The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
–Cleaning with a high pressure jet is forbidden.
Is there coolant present? Follow the recommendations below.
Is the solenoid valve subjected to significant fluctuations
or impacts?
Instructions:
–The solenoid valve must be correctly secured to its
mounting.
Contact with the engine environment is forbidden.Follow the recommendations below.
Check the turbocharger regulation control (no partial jamming, etc.).
Does the turbocharger control work? Carry out the necessary repairs.
Replace the solenoid valve.
If the fault is still present, contact the Techline.
