II - INSTRUCTIONS TO BE FOLLOWED PRIOR TO ALL OPERATIONS
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.
Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are to be used once only, and discarded after use.
Use lint-free cleaning cloths (cloth part reference 77 11 211 707). Using normal cloth or paper is prohibited. They are
not lint-free and could contaminate the fuel circuit. A lint-free cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into a clean receptacle.
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.
Blow compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system zones).
Check that no bristles are left.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves cover them with latex gloves to prevent contamination. IMPORTANT:
Before carrying out any work on the high pressure injection system, protect:
– the accessories and timing belts,
– the electrical accessories, (starter, alternator, electric power-assisted steering pump),
– the flywheel surface, to prevent any diesel from running onto the clutch friction plate,
– timing chain.

II - Cruise control/speed limiter management:
The cruise control function, when activated, allows you to keep the vehicle speed at a selected value
regardless of the driving conditions encountered.
Using the control buttons, the driver can increase or reduce the speed of the vehicle.
If the driver wishes to exceed the cruising speed, he may:
– press the accelerator pedal and exceed the cruising speed (the vehicle will return to the initial cruising speed
once the driver takes his foot off the pedal),
– press the system control buttons.
The cruise control function can be deselected either by:
– the system control buttons,
– deactivating the cruise control switch,
– when system events are detected, such as the brake pedal or clutch being pressed,
– when system errors are detected such as an inconsistent vehicle speed.
The cruise control function can also be temporarily disabled when the driver wants to increase the speed by
depressing the accelerator pedal. The cruising speed is resumed when the driver releases the accelerator pedal.
The vehicle will then attempt to reach the cruising speed at a controlled acceleration rate.
It is possible to reactivate the vehicle speed control and resume the last cruising speed after deactivation
(computer supply not cut off).
When activated (using the selection switch) the vehicle speed limiter function limits the vehicle speed to a
preselected value. The driver controls the vehicle in the normal way using the accelerator pedal until the cruising
speed is reached.
If the driver attempts to exceed this speed, the system ignores the pedal request and controls the vehicle speed
in the same way as the cruise control function, as long as the accelerator pedal is kept sufficiently depressed.
As with cruise control, the cruising speed can be altered using the one-touch control buttons or by pressing
and holding.
For safety reasons, it is possible to exceed the cruising speed by depressing the accelerator pedal beyond the pedal
position limiting value. The vehicle speed is fully controlled through pedal position, until the vehicle speed falls back
below the limit speed when the speed limiter function will once again be reactivated.
If the driver wishes to exceed the cruising speed, he may:
– exceed the accelerator pedal's kickdown point,
– increase it by pressing or pressing and holding the switch.
The speed limiter function can be deselected either:
– the system control buttons,
– by switching off the speed limiter switch,
– when system events are detected, such as the brake pedal or clutch being pressed,
– when system errors are detected such as an inconsistent vehicle speed.

If the fault becomes present during a road test at over 21 mph (35 km/h).
Special notes:
– the cruise control/speed limiter function is switched off.
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Check the condition of the clutch sensor connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel
Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 675).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Display status ET405 Clutch pedal switch (can only be displayed for Manual Gearboxes) which is normally
INACTIVE when the pedal is not depressed.
Depress the clutch pedal and note whether this status becomes ACTIVE.
If the status becomes ACTIVE when the clutch pedal is in the rest position.
Clear the fault, switch off the ignition, wait for the end of the power-latch and wait for the diagnostic tool message
(maximum wait 8 min): Loss of dialogue with the computer: EDC16 CP33, check the tool connection and the
computer supply voltage and switch on the ignition again.
Carry out a road test and then take a fault reading.
If the fault is still present, contact the Techline.

YES
When the driver depresses the clutch pedal, status ET034 becomes YES until
the ignition is next switched off.
If NO appears despite the clutch pedal being depressed, carry out the following
operations:
– Remove the clutch pedal switch, check the insulation between connections M
and86D of component 675, with the switch in the rest position.
– Repeat this operation with the switch engaged and check the continuity
between the two connections.
If these 2 checks are faulty, replace the switch.
Check the condition of the clutch switch connector (see Wiring Diagram Technical
Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2,
component code 675).
Check the condition of the engine management computer connector (see Wiring
Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II
ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure
(seeTechnical Note 6015A, Repairing electrical wiring, Wiring: Precautions
for repair), repair the connector, otherwise replace the wiring.
Then check the continuity and absence of interference resistance of the
connection:
•86D between components 120 and 675.
– Check for complete earthing on connectionM of component675.
If the connection or connections are faulty and there is a repair procedure (see
