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.

REPLACING THE INJECTORS
After replacing one or more injectors, re-enter the IMA codes.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
→ PROCEDURE to be followed after one or more injectors are replaced:
IMPORTANT
Cylinder no. 1 is located at the engine flywheel end.
–make a note of the IMA code(s) engraved on the injector body,
–enter these codes in the computer using command SC002 Enter injector codes, then follow the instructions given
by the diagnostic tool,
–once the command has finished,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–return to fault finding mode,
–select the Computer identification function from the main screen,
–check that the injector codes entered into the computer match those found on the bodies of the injectors:
–if the codes do not match, repeat the procedure for command SC002 Enter injector codes;
–if the codes do match, check system faults and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.Note:
The IMA coding (individual injector correction) is a calibration made in production on each injector to adjust
the flow accurately.
These correction values are etched onto the Bakelite body of each injector (6 alphanumeric characters) and then
entered into the computer which then controls each injector taking into account their manufacturing variation.
IMPORTANT
Engines can only operate correctly if the correct IMA codes have been entered.
If no code has been entered or if an invalid code has been entered, the fault DF276 Injector code
programming, is present and the engine will be in defect mode (speed heavily limited).
If another injector's code has been entered, the system will accept it but will make the wrong correction.
This could lead to engine damage, loss of performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present:
–when an attempt is made to start the engine,
–when the engine is running.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
The engine speed sensor is consistent with the camshaft sensor.
If the fault is present:
–it is impossible to start the engine or the engine stops,
–the level 2 warning light is lit.
Check the engine speed sensor connections.
Check the injection computer connections.
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the sensor is correctly mounted and that the flywheel target is not damaged.
Check that the gap between the engine speed sensor and the flywheel is 0.5 to 1.8 mm.
Measure the resistance of the engine speed sensor between terminals A and B of its black connector.
If the winding resistance is not between 510 Ω and 850 Ω at an engine temperature of 20˚C, replace the engine
speed sensor.
Check for continuity and the absence of interference resistance of the following connections:
Injection computer brown 48-track connector B
track B1Track A engine speed sensor
Injection computer brown 48-track connector B
track C1Track B engine speed sensor
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Repair if necessary.
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.

Check for continuity and absence of interference resistance on the following connection:
Camshaft sensor, track 3 + after ignition feed after relay
–If the measured voltage is correct with the sensor disconnected,

STATUS 4
Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- Either the cruise control is active, or
- 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 RZ007
“Fault memory”.
If status ET415 becomes STATUS 4 without pressing the 0 button, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the steering wheel, to the right.
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the injection
computer receiving a signal indicating 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,
- status ET703 Cruise control/speed limiter buttons,
- status ET704 Brake contact no. 1,
- and status ET705 Brake contact 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 for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
“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 Techline.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic

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,
