Fault finding – Function
SYSTEM FLOWCHART
The high pressure injection system is designed to deliver a precise quantity of diesel fuel to the engine at a set
moment.
The Siemens VDO piezo Common Rail system used on the K9K Step 2 engine is a second generation Common Rail
injection system. Fuel pressure in the rail can reach a maximum of 1650 bar.
The Siemens VDO piezo Common Rail system uses injectors which are controlled by piezoelectric actuators.
The fuel is pressurised by means of a high pressure pump then sent to a rail which supplies the four injectors.
The system includes two subsystems, which have different fuel pressure levels:
●the low pressure system which includes the tank, diesel fuel filter, internal fuel transfer pump and injector
return pipes,
●the high pressure system which includes the high pressure pump, rail, injectors and high pressure pipes.
There are a number of sensors and regulating actuators for controlling and monitoring the entire system.
It is fitted with a 112- track (or 128- track for Kangoo II) SIEMENS computer (SID 301 and SID 304).
The system comprises:
– a priming bulb,
– a diesel filter,
– a high pressure pump (HPP) with a fuel pressure solenoid valve (PCV), a fuel flow solenoid valve (VCV) and an
internal fuel transfer pump (ITP, low pressure pump),
– an injector rail,
– a rail pressure sensor,
– four piezoelectric injectors,
– a fuel temperature sensor,
– a coolant temperature sensor,
– a camshaft sensor,
– a TDC sensor,
– a turbocharger pressure sensor,
– an exhaust gas recirculation solenoid valve with integrated position sensor (EGR),
– an accelerator pedal potentiometer,
– an atmospheric pressure sensor integrated into the injection computer,
– an air mass flowmeter with integrated air temperature sensor,
– an air damper valve (Vdiag 44, 45, 48, 49 and 4D only),
– a temperature sensor upstream of the turbine,
– an antipollution system:
●a temperature sensor upstream of the particle filter (Vdiag 45, 49, 4D only),
●a temperature sensor downstream of the particle filter (Vdiag 45, 49, 4D only),
●a particle filter differential pressure sensor (Vdiag 45, 49, 4D only),
●a particle filter injector (Vdiag 45, 49, 4D only),
●a particle filter (Vdiag 45, 49, 4D only),
– a temperature sensor downstream of the catalytic converter,
– an electric fuel pump,
– an electric coolant pump (Vdiag 45, 49, 4D only),
– four heating elements and their control unit (Vdiag 45, 49, 4D only),
– four heater plugs,
– a water in the fuel detection sensor (optional).

Fault finding – Function13B
INTERSYSTEM EXCHANGES
The inter-system connections concerning the particular requirements of engine management are as follows:
●Request for injection computer to switch on the OBD warning light to warn of an OBD related pollution fault.
●Request to switch on the Level 1 warning light to warn of an operational safety fault with the engine
management system which may restrict performance.
●Request to switch on the Level 2 warning light to warn of an operational safety fault with the engine
management system which may result in the engine stopping.
●Request to switch on the Particle Filter and Service warning light to warn of an operational safety fault of the
particle filter system which may result in reduced performance or engine stoppage.
●Request to switch on the Engine overheating warning light to warn of an engine overheating fault or a fault
in the coolant temperature sensor.
●Request to switch on the Particle filter warning light to warn the driver that the particle filter is loaded with
particles (weight of soot more than 30.8 g). As soon as possible, the driver must drive at a speed of more than
25 mph (40 km/h) for 2 minutes to activate regeneration.
The driver must maintain a speed of more than 25 mph (40 km/h) until the particle filter warning light goes out
(Vdiag 45 and 49 only).
●Request to start the fan assembly for engine cooling and also for air conditioning purposes,
●Request to switch off the air conditioning compressor for engine programming requirements such as pulling
away, performance, anti-stalling, overspeed, etc.
●Request to switch off electrical consumers (passenger compartment heating resistor (if fitted), heated rear
screen, etc.) for engine operation purposes such as: pulling away, performance, anti-stalling,
overspeed, etc.
●Formulation of requests to engage electrical consumers and limit power as a function of rail conditions.
This last function is made possible with the introduction of alternator control. Formulation of requests enables
the smooth running of the engine to be improved in the critical operating phases, mainly at idle speed and
when pulling away. These requests pass via the multiplex network to the Protection and Switching Unit where
they are converted before being sent to the alternator.
In comparison to the version without a particle filter (K9K Step 2), the K9K Step 2 particle filter technical
specifications also include:
●Four temperature sensors spread along the exhaust system.
●One differential pressure sensor.
●One fuel injector with a dedicated electric fuel pump.
●An electric water pump (in addition to the mechanical pump) controlled by a relay to cool the turbocharger when
the engine is stopped (only for Clio III, Modus and Mégane II/Scénic II).
●Four heating elements and their control unit.
Oil Control System (OCS) (except Vdiag 44, 45 and 49)
This program takes into account the driving style of the user to warn him of the need for an oil change. This program
counts the number of miles since the last oil change, corrected by a factor which depends on the oil temperature.
When the number of miles exceeds a threshold, the customer is warned by a message to the instrument panel that
the drain must be performed.
After the oil change, the user must reset the oil change interval on the instrument panel.

Cruise control/speed limiter on/off switch:
This switch turns the cruise control/speed limiter on or off.
Water in diesel fuel sensor (optional):
This sensor indicates if water is present in the diesel.
Fan unit relay:
This relay actuates the motor-driven fan assemblies when a temperature threshold has been exceeded.
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).
Heater plugs:
The heater plugs preheat the combustion chamber so that the explosion of the fuel mixture occurs under the best
conditions to start the engine.
