EGR PROGRAMMING CUT-OFF
STATUS DEFINITIONThis status indicates the EGR valve programming cut-off.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80 °C
NONE
No EGR cut-off, the EGR valve is working properly in accordance with the
computer programs.
STATUS 1, 5, 6, 7, 9,
10, 12, 13, 15, 19
23, 24Switch off the ignition and wait 1 minute.
Switch the ignition on and check for faults.
Check the engine battery voltage with the engine switched off and the engine running.
If no faults are present or stored, restart the vehicle and test at idle speed.
Do not accelerate too much and reach an engine speed that is too high.
STATUS 3, 14, 16Accelerate above idle speed for a few seconds.
STATUS 2Check that the clutch pedal (ET405 "Clutch pedal switch") is not pressed and that the
vehicle has stopped completely.
STATUS 4, 17Test the present and stored faults and repair.
STATUS 8Reset the EGR offsets by referring to the interpretation of command SC036
"Reinitialise programming" and select "EGR valve".
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVE
Status ET703 becomes INACTIVE when none of the cruise control/speed limiter
buttons are pressed. These buttons are located on the steering wheel.
To carry out the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
removal-refitting).
If status ET703 does not display INACTIVE,
– check the condition of the cruise control/speed limiter +/- button and the condition of
its connector.
– check the condition of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
removal-refitting).
Measure the resistance of the following connections while pressing the "+" button
(on the button tracks):
– Connection code86G, 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.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS DEFINITIONThese statuses indicate the recorded engine status for failed regenerations when
driving.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
These statuses should only be interpreted if DF312 "Speed request" is present or

This status shows the stored engine status during a regeneration failure when driving:
NONE, + AFTER IGNITION, RUNNING, STOPPED.
Each STATUS between ET706 and ET715 corresponds to regeneration failures for which the mileage is recorded
from PR794 Stored regeneration failure no. 1 to PR803 Stored regeneration failure no. 10 (for example,
PR797 Stored regeneration failure no. 4 is related to ET709 Stored engine status no. 4).

Request by weight of soot
Regeneration has been requested following measurement of the maximum weight of
soot in the particle filter, without the particle filter warning light coming on.
STATUS2Request by estimated weight of soot
Regeneration has been requested following an estimate of the maximum weight of soot
in the particle filter, without the particle filter warning light coming on.
STATUS3Request by distance travelled
Regeneration has been requested as the distance travelled since the last successful
regeneration has reached the maximum authorised value (the particle filter warning
light has not come on).
STATUS4Request by number of failed regenerations or soot weight
This status corresponds to the appearance of DF312 "Speed request".
This corresponds to the maximum number of failed regenerations or to the maximum
weight of soot in the particle filter, with the particle filter warning light coming on.
