Note:
the left and right-hand xenon bulb computers are powered when the dipped headlights are lit.
Therefore fault finding can only be carried out on them after the ignition has been switched on in fault finding mode
(forced + after ignition feed) and the dipped headlights have been switched on.
For vehicles with a radio frequency remote control - key, use the key to switch off the ignition.
Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when using the diagnostic tool after
switching on the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
– the electrical connections that correspond to the fault,
– the connectors for this connection,
– the resistance of the component detected as defective,
– the condition of the wires.
Refer to paragraphs 4.1 Checking wiring and 4.2 Checking connectors
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because
the data is inconsistent. Therefore, this stage is used to:
– carry out fault finding on faults that do not have a fault display, and which may correspond to a customer complaint.
– check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult
the corresponding fault finding page.
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the protectors, insulation, and routing of the wiring, as well as the mountings.
Physical inspection
While manipulating the wiring, use either the diagnostic tool to detect a change in status from "stored" to "present",
or use the multimeter to view the status changes.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result is: 1 Ω ± 1 Ω for each connection. The line must be fully checked,
and the intermediate connections are only included in the method if this saves time during the fault finding
procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured value
should be 1 Ω ± 1 Ω

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.
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.
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 also be discarded.
Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are single-use only. Once used, they must be thrown out.
Use lint-free cleaning cloths (cloth part reference 77 11 211 707). Using normal cloth or paper is prohibited. They are
not lint-free and could contaminate the fuel circuit. Each cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.

Blast compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system zones). Check
that no bristles remain.
When wearing leather protective gloves cover them with latex gloves to prevent contamination.
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Department. The plugs must not be reused under any
circumstances.
Seal the pouch shut, even if it has to be opened shortly afterwards. Ambient air carries contamination.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once they
have been plugged.
Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been opened.
These items could allow contamination to enter the system.
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the vehicle.

System outline
The DCM1.2 injection system used on the K9K engine is an electronically-managed high pressure injection system.
The fuel is compressed by a high pressure pump then stored in a rail that feeds the injectors. Injection takes place
when a current pulse is applied to the injector holders. The amount injected is proportional to the rail pressure
and the applied pulse length, and the start of injection is synchronised with the start of the pulse.
The system includes two subsystems, which have different fuel pressure levels:
– The low pressure circuit contains the tank, the diesel fuel filter, the transfer pump and the injector holder
return pipes,
– the high-pressure system includes the high-pressure pump, rail, injector holders and high-pressure pipes.
Finally, there are a certain number of sensors and regulating actuators for controlling and monitoring the entire
system.
Functions performed:
These are calculated by the computer using signals from the following sensors:
– engine speed sensor (Crankshaft + Cam lobe for synchronisation),
– accelerator pedal sensor,
– coolant temperature sensor,
– rail pressure sensor,
– atmospheric pressure sensor,
– accelerometer,
– inlet manifold pressure sensor.

The flow of fresh air entering the engine is given by a hot wire ratiometric sensor. This
flow sensor facilitates control of the amount of exhaust gas sent for recirculation, thus
K9K 800 802 (Euro 4) ensuring the best possible recirculation rates. An air temperature sensor is integrated
into the flow sensor.
Air flow measurement facilitates closed-loop control via the EGR valve.

The quantities to be injected and their respective timing are converted into:
– a reference tooth,
– the time between this tooth and the start of the pulse,
– the time during which the supply to the injector holder is on.
An electrical current (pulse) is sent to each injector holder according to previously calculated data. The system
carries out one to four injections (one pilot injection, one pre-injection, one main injection, one post-injection).
The general principle is to calculate the total injection flow which is then divided between the injection stages to
promote correct combustion and reduce pollutant emissions.
An accelerometer checks some of the fuel injection deviation. This has several functions:
– Protecting the engine by detection of injection system leaks.
– Checking the quantity injected by measuring deviations and variations.
By changing both the injection duration and advance, the system readjusts the quantity of fuel injected
and the mixture's moment of ignition.

With smaller holes, less fuel will be able to be introduced at a given pressure, which limits the power. To offset this
disadvantage, the quantity of fuel injected must be increased, which means increased pressure (and more holes in
the injector nozzles). In the Delphi Common Rail injection system, the pressure in the rail can reach 1600 bar
and must be constantly controlled. The measuring circuit comprises an active pressure sensor on the rail connected
to an analogue port on the computer.
The High Pressure pump is supplied at low pressure (5 bar) by a built-in transfer pump. This pump supplies the rail.
The rail filling pressure is controlled by the filling valve (IMV) and the discharge pressure is controlled by the injector
valves. This compensates for pressure drops. The filling actuator enables the high pressure pump to supply
the exact quantity of diesel fuel required to maintain the rail pressure. This mechanism minimises the heat generated
and improves engine output.
In order to discharge the rail using the injector valves, the valves are actuated by short electrical pulses which are:
– short enough not to open the injector (fuel passes through the return circuit from the injectors),
– long enough to open the valves and discharge the rail.
The fuel surplus is sent back to the fuel filter or the tank, according to its flow. If there is no IMV* control, the rail
pressure is limited by a discharge valve on the pump.
The DCM1.2 system injectors must be calibrated with corrective values so that their flow may be adjusted precisely.
Each injector is calibrated for different pressures on a test bench, and its specifications are shown on a label
attached to the body of the injector holders. These individual correction values are then entered into the computer
memory, which can control the injectors, taking their manufacturing variations into account.

The pump lubrication goes through a booster cycle during which the pump is filled and pressurised before
"transferring" the diesel fuel to the rail.
This lubrication goes through a procedure called new pump chamber filling, which prevents starting for
approximately 10 seconds, which is the time required for filling the pump and starting. For vehicles with keys,
if the key is released before the end of this "initial starting" phase there is no need for a power latch phase to be
completed before a fresh attempt to start the vehicle.
This procedure is run after the first start in the factory, after a computer is replaced if the parameters relating to
the rail pressure have not been copied into the new computer, and also after reprogramming of the injection
computer.
Because of the combination of several parameters such as the diesel fuel temperature, part wear, clogging of
the diesel filter etc., the system limit may be reached during its service life. If this happens, the rail pressure cannot
be maintained because the pump lacks the necessary capacity. If the pump lacks the necessary capacity, this
programming will therefore reduce the requested flow to a value that will enable the pressure monitoring system to
control the pressure again.
The customer may have noticed a loss of vehicle performance when this program is activated (depending on
the vehicle, this programming can be confirmed by ET563 Flow capacity function). This is normal operation of
the injection system.

On models with air conditioning, the DCM1.2 system allows the air conditioning to be deactivated under certain
operating conditions:
– when requested by the driver,
– when starting the engine,
– if the engine overheats (in order to reduce the power the engine has to supply),
– when the engine speed is kept at a very high level (to protect the compressor),
– during transition phases (e.g. high acceleration demand for overtaking, anti-stalling and moving off). These
conditions are only taken into account if they do not occur repeatedly, so as to prevent system instabilities
(erratic deactivation),
– when certain faults appear.
The driver requests the instrument panel to switch on the air conditioning. The signal is sent to the injection computer
via the multiplex line network. The cold air request is authorised or denied depending on the pressure measured. If
this pressure is outside the operating limits, the cold loop program is not activated.
Note:
Fan unit actuation requests can be sent by the injection computer, but these are sent via the multiplex line. These
requests depend on the air conditioning, but also on the engine coolant temperature and vehicle speed.
In a direct injection engine, fuel is injected directly into the combustion chamber. This leads to heat being lost
through the upper part of the engine and consequently, the cylinder head cooling system is smaller in size.
The effect of this is that the temperature of the coolant which flows through this circuit rises more slowly. This coolant
is also used by the passenger compartment heating system. In very cold conditions, it is therefore difficult to achieve
a comfortable passenger compartment temperature quickly.
To reduce the time taken to produce heat, air heating elements, called passenger compartment heating resistors,
are fitted in the passenger compartment heating circuit. The UCH decides whether or not to switch on the passenger
compartment heating resistors, and the UPC or the injection physically controls the heating elements. The injection
computer determines whether to reduce the power supplied to the passenger compartment heating resistors
according to the alternator load and also whether to inhibit the operation of the passenger compartment heating
resistors according to the engine speed, the load, and the vehicle speed.

When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the
driving conditions encountered. Using the control buttons, the driver can increase or reduce the speed of the vehicle.
The cruise control function can be deactivated either using the control buttons, or by switching off the cruise control
function selector switch or when system events are detected such as the brake or clutch pedal being depressed,
or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle deceleration.
The cruise control function can also be temporarily overridden when the driver wants to resume control of
the vehicle and exceed the selected cruising speed by pressing the accelerator pedal, which causes the controlled
fuel flow to be exceeded. The cruising speed is resumed when the driver releases the accelerator pedal.
It is possible to reactivate cruise control and to return to the last cruising speed after the function has been
deactivated for whatever reason, during the same cycle of use (computer supply voltage not cut off). The vehicle will
then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When activated (using the selection switch), the vehicle speed limiter function limits the vehicle speed to
a preselected value.
The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached. If an
attempt is made to exceed this speed, the system will ignore the pedal request and will limit the vehicle speed,
provided that the driver continues to depress the accelerator pedal.
As with the cruise control function, the limit speed can be altered using the control buttons by pressing briefly or by
pressing and holding (pressing and holding not active on Kangoo 2).
For safety reasons, the limit speed can be exceeded by depressing the accelerator pedal beyond the pedal position
limit value. The vehicle speed will then be totally controlled by the pedal until the speed falls back below the cruising
speed when the speed limiter function will once again be reactivated.
The driver has the following controls for the cruise control - speed limiter function:
– accelerator pedal,
– brake pedal,
– clutch pedal (not for sequential gearbox),
– function selector switch, used to select cruise control or speed limiter operating mode,
– activation switch on the steering wheel,
– required speed adjustment switch on the steering wheel.

The computer manages the data display on the instrument panel relating to engine operation. This covers five
functions: the OBD warning light for European On Board Diagnostics (EOBD), pre-postheating, coolant temperature,
and Level 1 (non critical fault) and Level 2 (emergency stop) engine faults. These five functions are represented by
five warning lights or messages displayed by the trip computer.
The OBD fault warning light is used to warn the driver of the presence of injection faults producing excessive
pollution or that the EOBD system is deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three consecutive
driving cycles.
The visual check of the warning light when the power is switched on (automatic test procedure managed by
the instrument panel) is carried out by the injection computer. It lasts 3 seconds or until the engine starts for
the New Twingo and Kangoo 2.
If a confirmed OBD fault causes the OBD warning light to come on, there should be no flashing after the warning
light illumination test. The instrument panel will also display the message: Check emission control.
The gearbox computer, if fitted, may also request the illumination of this warning light.
Note:
This warning light comes on only if the vehicle is EOBD approved.
Level 1 warning
If there is a minor fault, the computer may request a level 1 warning to be displayed. Usually, the instrument panel
switches on the SERVICE warning light and sends out a "Check the injection" message. Refer to the operation of the
instrument panel (see 83A, instrument panel).
Note:
The SERVICE warning light will come on if the instrument panel is configured as cruise control - speed

The injector rail receives and redistributes fuel under high pressure to the injectors.
Solenoid injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.
Catalytic converter:
Its role is to convert pollutant gases into harmless gases.
Heater plugs:
The heater plugs create a hot point in the combustion chamber to improve starting in low temperature conditions.
They are also used to improve idle speed stability under some conditions.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Turbocharger control solenoid valve (K9K 724, 766, 802, and 812 only):
This solenoid valve controls the turbocharger wastegate.
EGR valve:
The exhaust gas recirculation enables nitrogen oxide (NOx) emissions to be reduced significantly.
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 as well as 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 (TDC), it can be 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.

IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.).
Wait for the engine to cool (engine coolant temperature less than 60°C and air temperature less than 50 °C).
IMPORTANT
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 the Cruise control position to activate the Cruise control function.
Switch in the Speed limiter position to activate the Speed limiter function.
Before removing any old computer as an After-Sales operation, save the following data using the diagnostic
tool:
– The C2I (individual injector correction) parameters and the engine adaptives using command SC003 Save
computer data.
The system can be programmed by the diagnostic socket using the RENAULT CLIP diagnostic tool (refer to
Technical Note 3585A, Computer programming and reprogramming procedure, and follow the instructions
provided by the diagnostic tool).
IMPORTANT
AFTER A PROGRAMMING OPERATION, DO NOT CONNECT THE BATTERY FOR AT LEAST 30 minutes (to
carry out other work on the vehicle).

Note:
C2I (individual injector correction) is a calibration carried out in the factory on each injector to adjust the flow
of each injector precisely.
The correction values are written on a label affixed to each injector and then are entered in the computer, which
can then actuate each injector by taking account of their manufacturing variation.
The system can be set up using the diagnostic socket with the RENAULT CLIP diagnostic tool.
To do this, reprogram C2I into the computer using the following commands:
Cylinder 1 injector: command VP001 Cylinder 1 injector code (cylinder at flywheel end)
Cylinder 2 injector: command VP002 Cylinder 2 injector code
Cylinder 3 injector: command VP003 Cylinder 3 injector code
Cylinder 4 injector: command VP004 Cylinder 4 injector code
The four C2I can be entered using command SC002 Enter injector codes.
The technician can use the appropriate command to re-enter the new C2I for the replaced injector and to erase the
old C2I.
Only after simultaneously replacing at least three injectors, reset the injector adaptives, using command RZ004
Pressure regulation adaptives.
IMPORTANT
When reprogramming the computer, only carry out the following procedure after command AC028 Static
test has been run (see Computer reprogramming operation).
PROCEDURE
Refer to Technical Note 5011A, Repriming Delphi high pressure pumps on K9K engines.
If replacing the EGR valve, it is essential to program the new valve's offset position. To do this, clear the old offset
using the EGR programming clearing procedure and run command RZ002 EGR adaptives.

PARAMETER This parameter indicates the vehicle distance in km when the warning requesting the
DEFINITION oil change was displayed on the instrument panel.
The oil status is calculated by the oxidation program in the injection computer, depending on the engine revs.
When this count reaches a certain threshold before the end of the oil change period, the injection computer sends
a signal to the instrument panel, which will display "service required soon". PR873 corresponds to the vehicle
distance at the time this signal is sent.
The instrument panel computer will then count 900 miles (1500 km) before displaying the message "service
required".
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an oil change
within the remaining 900 miles (1500 km).

NOTES
Certain faults make it impossible to carry out this test - deal with these first.
The command AC029 High pressure circuit sealing test enables a high pressure circuit sealing test to be
carried out when the engine is running.
This command can locate a leak in the high pressure circuit if a union is incorrectly fitted or screwed on. This test
does not identify a minor leak due to a union not being tightened to torque.
This command can only be used if the engine temperature is above 60°C.
Watch out for any objects (tools or others) on the sides of the engine housing during the 4 accelerations
(possible vibrations).
Use command AC029 High-pressure circuit sealing test; the engine will automatically carry out a cycle of
four accelerations to increase the rail pressure and check for leaks in the high pressure circuit.

Command AC029 High pressure circuit sealing also checks the return volume of each injector to detect
any leaks inside the injectors.
Be careful with any objects (tool or other) on the engine housing during the four cycles of the operation
(possible vibrations).
Tooling required
– Mot. 1711 Injector flow measuring kit.
Or: Use four tubes of internal diameter 4 mm and approximately 50 cm long, and four graduated measuring
cylinders.
Procedure
– Check that the engine coolant temperature is above 60°C,
– switch off the ignition,
– disconnect the return pipes from the four injectors,
– cap the pump venturi tube to prevent the low-pressure circuit from depriming,
– connect the four transparent tubes in place of the return pipes,
– put the other ends of the four pipes into four graduated measuring cylinders.
When all the preparations are complete, start the engine and leave it running:
for Euro 4 engines: K9K 766 - 768 (Clio III and Modus); K9K 724 (Mégane II
30 seconds
and Scénic II); K9K 740 -718 (New Twingo); K9K 800 - 802 - 812 (Kangoo 2).
Let it idle for 2 minutes for Euro 3 type engines: K9K 750 - 752 (Clio III and Modus).
Note:
These time periods must be respected for the test results to be interpreted correctly.
– Run command AC029 High pressure circuit sealing check.
The engine will carry out automatically a cycle of four accelerations to increase the rail pressure and measure
internal injector leaks under these conditions.
– When the cycle has finished, run command AC029 High pressure circuit sealing test a second time to
obtain the correct return volume reading for each injector.
– Switch off the engine at the end of the cycle.

the test adapter (test IMV, Mot. 1711),
– electrically disconnect the 4 injectors,
– switch on the ignition, connect the diagnostic tool and re-establish dialogue with the injection system,
– go to the Main computer statuses and parameters screen,
– run the starter for 5 seconds,
– read the maximum rail pressure value PR038 Rail pressure during the test on the diagnostic tool.
If the rail pressure (PR038 Rail pressure) is lower than 1050 bar, run test 6: High pressure system check.
– Switch off the ignition, and reconnect the four injectors electrically,
– disconnect the test filling actuator (test IMV) and reconnect the low-pressure actuator connector (IMV) to the
pump,
– switch on the ignition again, and clear the injection faults using the diagnostic tool.
If the rail pressure (PR038) is greater than 1050 bar, the repair is correct.

To check that the diagnostic tool is not causing the fault, try to establish dialogue with a computer on another
vehicle. If the diagnostic tool is not the cause and communication cannot be established with any other computer
on the same vehicle, it is possible that another computer is disrupting the multiplex network. Check the battery
voltage and make the necessary adjustments to obtain a correct voltage (9.5 V < Battery voltage < 17.5 V).
Run fault finding on the multiplex network using the diagnostic tool (see 88B, Multiplexing).
Check the presence and the condition of the injection fuses on the UPC and on the engine fuse box.
Check the connection of the computer connectors and the condition of its connections.
Check the injection computer earths (quality, oxidation, earth bolts secure on the battery terminal).
Check that the supply to the computer is correct:
