Fault finding – Cleanliness guidelines
I - HAZARDS 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 - 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 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.

Fault finding – Function13B
Engine synchronisation
One of the determining factors for fuel injection control is knowing the position of each of the pistons in their
respective cylinders at all times.
The angular position is measured using a TDC sensor triggered by machined teeth on the flywheel. The flywheel
has 60 teeth, with 2 teeth missing which forms a notch which is used as a reference point for the 1
st cylinder.
A second sensor (Hall-effect), excited by a machined tooth on the camshaft, and turning at half the engine speed,
provides information on the progress of the injection cycle. When the piston of cylinder 1 is at top dead centre (TDC),
either at the end of the compression stroke or at the end of the exhaust stroke, the camshaft sensor enables
a distinction to be made between these two states.
By comparing the signals from these two sensors, the computer is able to provide all of its systems with
synchronisation parameters, namely: the angular position of the flywheel, engine speed, the number of the active
injector and the progress of the injection cycle.
The module supplies the system with the rotation speed signal.
The camshaft sensor is only used when starting the engine. As soon as the engine is running by itself (not being
cranked by the starter), the signal provided by the TDC sensor is sufficient. A camshaft sensor fault, when the
engine is running, does not prevent the engine from operating correctly.
Quantity of fuel injected and control of start of injection
The parameters for controlling injection are, for each cylinder, the quantity to be injected and the start of injection.
These parameters are calculated by the injection computer using the following information:
– Engine speed.
– Accelerator pedal position.
– Turbocharging air pressure.
– Coolant temperature.
– Air temperature.
– Fuel temperature.
–Air flow.
– Pressure of fuel in the rail.

Fault finding – Function13B
TDC sensor:
The angular position is measured using a magneto-inductive sensor triggered by machined teeth on the flywheel.
This sensor gives the engine speed and the position of the crankshaft for injection.
Camshaft sensor:
This sensor gives a signal to perform the injection cycle. When the piston of cylinder 1 is at top dead centre, either at
the end of the compression stroke or at the end of the exhaust stroke, the camshaft sensor enables a distinction to
be made between these two states.
Electric coolant pump:
The electric coolant pump is activated when the coolant temperature has reached a significant temperature
threshold when the engine has stopped.
The role of the electric water pump is to cool the turbocharger when the engine stops (Vdiag 45, 49 only).
Refrigerant pressure sensor:
The role of the sensor is to measure the refrigerant fluid pressure in the air conditioning circuit.
Electric fuel pump:
The pump is controlled by a relay during each regeneration or purge phase; it is submerged in the tank and is
connected to the secondary fuel circuit only.
Coolant temperature sensor:
The engine coolant temperature sensor informs the computer about the engine coolant temperature.
Air temperature sensor:
The air temperature sensor is fitted in the inlet manifold and informs the computer about the temperature of the air
sucked up by the engine.
Turbocharging pressure sensor solenoid valve:
This solenoid valve operates the turbocharger wastegate pneumatic circuit to lower the turbocharging pressure.
Catalytic converter:
Its role is to convert pollutant gases into harmless gases.
Catalytic converter downstream temperature sensor:
This sensor gives the temperature of the exhaust gas at the catalytic converter output.
Turbine upstream temperature sensor:
This sensor gives the temperature of the exhaust gas at the turbine inlet.
Particle filter downstream temperature sensor:
This sensor gives the exhaust gas temperature at the particle filter outlet (Vdiag 45, 49, 4D only).
Particle filter upstream temperature sensor:
This sensor gives the exhaust gas temperature at the particle filter inlet (Vdiag 45, 49, 4D only).
Particle filter differential pressure sensor:
A differential pressure sensor monitors the status of the particle filter (particle weight) and triggers regeneration.
The role of the sensor is to inform the computer of the pressure difference between particle filter inlet and outlet
(Vdiag 45, 49, 4D only).

STATUS 4
Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button is
pressed.
Status ET415 becomes STATUS 4 when driving with:
– either the cruise control is active, or
– the speed limiter is active
– and when the "0" button is pressed by the driver.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.
STATUS 5Cruise 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,
– of status ET703 Cruise control - speed limiter buttons,
– of status ET704 Brake switch no. 1,
– of 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 shown on
the diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 5, deal with any faults that are present or stored in
the injection computer.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
