Fault finding – Cleanliness guidelines
I - RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated with
contamination are:
–damage to or destruction of the high pressure injection system,
–components jamming,
–a component leaking.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a
few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the injectors.
What are the sources of contamination?
metal or plastic swarf,
–paint,
–fibres:
–from cardboard,
–from brushes,
–from paper,
–from clothing,
–from cloths,
–foreign bodies such as hair,
–ambient air,
–etc.
II - NOTES TO BE FOLLOWED BEFORE ANY OPERATION
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.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections. In
addition, moisture may collect in the connectors and create electrical connection faults.
IMPORTANT
Before any work is carried out 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.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present during a road test.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the ABS computer connections.
Check the injection computer connections.
Repair if necessary.
Run fault finding on the multiplex network, (see 88C, Airbags - seat belt pretensioners) and the ABS, (see 38C,
Anti-lock braking system).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another 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.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
is pressed. These buttons are located on the steering wheel.
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.
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 these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connections while pressing the + button
(on the button tracks):
●Connection code 86G, 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 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 the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic tool

(CONTINUED 1)
DECREASEStatus ET703 becomes MINUS 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 change to MINUS, 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 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connection whilst pressing the - button (on
the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 100 Ω, check the continuity of the connection 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 the wiring
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 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 0Ω, 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 the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

TEST6 Turbocharger
IMPORTANT
Perform these checks without removing the turbocharger and with the vehicle ignition switched off.
Check the turbocharger shaft
WARNING
Respect the following safety precautions:
–wear heat resistant gloves when the engine is hot,
–do not wear loose or baggy clothing and do not wear loose hanging jewellery,
–be aware that the cooling fan assembly may be triggered and pay attention to the operation of the accessories
belt or belts.
Note:
The turbocharger shaft is the shaft connecting the compressor wheel and the turbine wheel.
According to the vehicle type, maximum visual access will either be from above or from below.
Disconnect the air pipe located between the turbocharger and the air filter.
Wearing gloves, check the operation of the turbocharger shaft by turning the vanes manually without forcing.
Is there a point of resistance when the shaft is rotated?
Does the compressor wheel touch the turbocharger housing?
If for these 2 questions the response is NOIf YES for one of these 2 questions
Replace the turbocharger (see MR 364 (Mégane II) or
370 (Scénic II), Mechanical, 12B, Turbocharging,
Turbocharger: Removal - Refitting and Technical
Note 3938A, Broken turbocharger: Replacement
