Special notes:
The cruise control/speed limiter function is inhibited.
Use bornier Elé. 1681 for all operations on the injection computer connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
If fault DF051 is present, refer to the Cruise control/Speed limiter section of the conformity check and refer to
interpretation of statuses ET042 Cruise control/Speed limiter, ET415 Cruise control/Speed limiter
deactivation and ET703 Cruise control/Speed limiter buttons.
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values

ET415
(CONTINUED 2)
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.
- 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 that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, refer to 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.
Also check the operation of the accelerator pedal, and check with the diagnostic tool for
a fault connected with this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
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.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
INACTIVEStatus 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 these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane II) or 372
(Scénic 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 INCREASE 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 INCREASE, check the condition of the cruise control/
speed limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane) or 372
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting)
Measure the resistance on 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 for
the button when the button is in the rest position.
If there is continuity, replace the +/- control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

DECREASEStatus ET703 becomes DECREASE 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 DECREASE, check the condition of the cruise control/
speed limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,

Measure the resistance of the following connection whilst pressing the "-" button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 100 Ω, check the continuity of the button in rest
position.
If there is continuity, replace the +/- control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
SUSPENDStatus ET703 becomes SUSPEND when the cruise control/speed limiter 0 button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to SUSPEND, check the condition of the cruise control/
speed limiter R/0 button, and the condition of its connector.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,

Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 0 Ω, replace the R/0 control button.
If there is continuity, replace the R/0
control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

ENTER INJECTOR CODES
NOTESThis command is carried out after the replacement of the injectors, and only if the
vehicle is configured with IMA (ET104 Injector code use YES).
If this command is not run, the fault DF276 Injector code programming will be
present.
IMPORTANT
Letters Q and J, and figures 0 and 9 are not used in IMA codification.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located at the engine flywheel end.
Procedure to be followed:
– Read the 6-character alphanumeric codes etched on the upper section of the injector bodies.
– Select the cylinder number for the cylinder concerned in the Desired column, then confirm.
– Enter the injector code displayed for the cylinder.
– Enter the new codes for each cylinder, then confirm.
– When the command is completed, the modified codes appear in the Current column.
– Check that the codes correspond to those read earlier.
– If the codes entered appear in neither the Current column nor the Desired column, check the codes read and
make sure the data has been entered correctly.
– Exit fault finding mode.
– Switch off the ignition and wait 30 seconds.
– Switch the ignition back on and check for faults.
–The DF276 Injector code programming should be stored.
If the fault is still present, the command has not been run correctly.
Start the procedure again and follow the instructions.
Switch off the ignition.
If all these checks still do not enable the command to be confirmed, contact the Techline.
AFTER REPAIRRestart the conformity check from the beginning.
