PRECAUTIONS/RISKS
The main recommendation regarding the system is:
Never electrically disconnect the injectors with the engine running.
The piezoelectric technology used for the injector system means that the injectors receive a control pulse to open
and another control pulse to close. If the injector is disconnected between these 2 pulses while the engine is
running, i.e. during the actual injection process, the injector will remain open long enough to create very
unfavourable thermodynamic conditions in the cylinder(s) or generate hydraulic pressure which may result in
engine damage. Tool fault Associated DTC Diagnostic tool title

Fault finding – Function13B
High pressure pump:
The pump draws in fuel from the tank, which passes through a fuel filter and supplies the fuel injectors.
Rail pressure sensor:
This sensor is fitted to the rail and shows the pressure inside the rail.
Rail pressure regulator:
This component regulates the high pressure of the fuel in the injection system.
Fuel flow regulator:
This component regulates the fuel flow of the injection system.

Piezoelectric injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.
Vacuum pump:
The vacuum pump is driven by the camshaft. The pump provides the vacuum required to operate the following
components: control solenoid valve, brake servo.
Control solenoid valve:
The solenoid valve connects the vacuum pump and the control diaphragm of the turbocharger blades.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Intake air pressure sensor:
This sensor measures the pressure at the turbocharging air cooler output before the damper valve.
Turbocharger pressure sensor:
This sensor measures the pressure at the turbocharging air cooler output before the damper valve.
Air mass flow meter:

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:

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).

Accelerator potentiometer:
The accelerator potentiometer informs the computer about the position of the accelerator pedal (engine load).
Brake pedal switch:
The brake pedal switch informs the computer about the pedal status.
Clutch pedal switch:
The clutch pedal switch informs the computer about the pedal status.
Particle filter injector:
The particle filter injector is a low pressure injector. This injector allows the temperature of the second catalytic
converter to be raised to assist with regeneration of the particle filter (Vdiag 45, 49, 4D only).
Only on Kangoo 2: an evaporator plate is present at the particle filter injector outlet, at the level of the bracket
between the exhaust pipe and the catalytic converter.
Heating elements:
The heating elements heat the engine coolant to enhance user comfort (Vdiag 45, 49, 4D only).

Fault finding – Defect and safe modes
DEFECT MODES:
Accelerator pedal defect mode (Limp-home):
This defect mode prevents an immobilising fault; the vehicle can be driven well enough for it to reach the nearest
dealer.
This function provides a virtual driver demand which controls the engine speed at 1800 rpm for each gear engaged,
then limits the vehicle's speed to 48 mph (80 km/h).
The idle speed is equal to the idle speed setpoint if the brake pedal is depressed, otherwise the idle speed is
set to 1800 rpm to ensure the vehicle pulls away in all conditions.

COMPUTER REPROGRAMMING OPERATIONS
The system can be reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic tool (see
Technical Note 3585A, Computer programming and reprogramming procedure).
Note:
Before reprogramming the injection computer, move the main Cruise control - Speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational. The procedure for resetting the function is as
follows:
– Vehicle ignition on.
– Main switch in rest position (the computer then detects the rest position).
– Switch in Cruise control position to activate the Cruise control function.
– Switch in Speed limiter position to activate the Speed limiter function.
While the computer is being reprogrammed the fan assemblies are triggered automatically.
Before reprogramming the computer:
– Save the computer data to the diagnostic tool (engine adaptives) by performing command SC003 Save
computer data.
After any computer reprogramming operation:
– Switch the ignition off and then on again,
–Use the diagnostic tool to carry out the following procedures:
– run command RZ019 Programming reinitialisation.
– run command SC001 Write saved data to restore the engine adaptives,
– run command SC013 Enter VIN,
– start the engine (warning: the start-up phase may last up to 30 seconds),
– after injection computer reprogramming, stored faults may appear in other computers. Clear the fault memory of
these computers,
– carry out a road test followed by another check with the diagnostic tool.
DO NOT CARRY OUT ANY INJECTOR CODE WRITING ON THE SIEMENS SID304 AND 301 INJECTION
SYSTEMS.IMPORTANT
Switch on the diagnostic tool (mains or cigarette lighter supply).

REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.
