Instructions to be followed before any work is carried out on the injection system:
Protect the accessories and timing belts, the electrical accessories (starter, alternator, electric power-assisted
steering pump) and the mating face to prevent diesel fuel spilling onto the clutch friction plate.
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.
Ensure that you have hermetically resealable plastic bags for storing removed parts. There is less risk of parts
stored in this way being exposed to contamination. These are single-use bags; after use they must be discarded.
Use lint-free cleaning cloths (part no. 77 11 211 707). Using normal cloth or paper is prohibited. They are not lint-free
and could contaminate the fuel circuit. Each cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.
Blast compressed air over the cleaned parts (tools, workbench, and the parts, unions and injection system area).
Check that no bristles remain.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves cover them with latex gloves to prevent contamination.
Instructions to be followed during the operation
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system. The
plugs to be used are available from the Parts Department. They must not be reused under any circumstances.
Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries impurities.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once they
have been plugged.
Using a brush, thinner, air gun, rifle-type brush or normal rag is strictly prohibited once the circuit has been opened.
These items are likely to allow impurities to enter the system.
If a component is being replaced with a new component, do not remove the packaging until it is ready to be fitted to
the vehicle.

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.

AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
