1. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks caused by the introduction of
contamination are:
– damage to or destruction of the high pressure injection system,
– a component seizing up,
– a component losing its sealing.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles
a few microns in size) should have penetrated the system during dismantling.
The cleanliness guidelines must be applied from the filter through 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,
– the ambient atmosphere,
–etc.
2. 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.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 faults in the electrical connections.
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.

Particle filter:
The particle filter retains the particles for destruction during regeneration, preventing these particles from being
discharged into the atmosphere (engine type F9Q816 only).
TDC sensor:
The angular position is measured using a magneto-inductive sensor triggered by the machined teeth on the engine
flywheel. This sensor gives the engine speed as well as the position of the crankshaft for injection.
Camshaft sensor:
This sensor provides a signal to perform the injection cycle.
When the piston for cylinder 1 is at top dead centre (TDC), it may be either at the end of the compression stroke or
at the end of the exhaust stroke. The camshaft sensor makes the distinction between these two states.
Electric coolant pump:
The electric water pump is activated if the coolant temperature has reached a significant temperature threshold
when the engine has stopped.
Role: to cool the turbocharger when the engine is stopped.
Refrigerant pressure sensor:
Its role is to measure the refrigerant pressure in the air conditioning circuit.
Heating elements:
The heating elements heat the engine coolant to improve user comfort (only on certain types of F9Q816 engine
in Vdiag 48).
Engine coolant temperature sensor:
The engine coolant temperature sensor informs the computer of the engine coolant temperature.
Air temperature sensor:
The air temperature sensor is fitted inside the inlet manifold and informs the computer of the temperature of the air
taken in by the engine.
Turbocharging pressure sensor solenoid valve:
This solenoid valve operates the turbocharger wastegate pneumatic circuit to lower the turbocharging pressure.
Catalytic converter:
The role of the catalytic converter is to convert pollutant gases into harmless gases.
Fan unit relay:
This relay controls the activation of the engine cooling fan assembly when a temperature threshold has been
exceeded.
Accelerator potentiometer:
The accelerator potentiometer informs the computer of the position of the accelerator pedal (engine load).

REPLACING THE INJECTORS
After one or more injectors have been replaced, enter the IMA codes again and then run command SC036
Reinitialise programming.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
PROCEDURE to be followed after replacing one or more injectors:
– Note the "IMA" code(s) engraved on the injector bodies,
– 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 and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching the
ignition back on.
– Return to fault finding mode.
– select the Identify computer 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, restart the command SC002 Enter injector codes procedure.
– If the codes correspond, run command SC036 Reinitialise programming,
–select Injectors as the type of operation, then follow the instructions given by the diagnostic tool.
– Then check the 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 another check with the diagnostic tool.
End of the procedure.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 (7 alphanumeric characters) and then
entered into the computer which then controls each injector taking into account its individual manufacturing
variation.
IMPORTANT
Cylinder no. 1 is located on the engine flywheel end.
IMPORTANT
Engines can only operate correctly if the correct IMA codes have been entered.
If no code has been entered, or if an implausible code has been entered, fault DF276 "Injector Code
Programming" will be present, and the engine will be in defect mode (engine speed is reduced
significantly).
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.
