Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after 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 instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section 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 faulty,
– the condition of the wires.
Refer to paragraphs 3.1 Checking the wiring and 3.2 Checking the 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.
Customer complaints – Fault finding chart
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 summary of the overall procedure to follow is provided on the following page in the
form of a flow chart.

Some vehicles have adopted a sensor for detecting water in the diesel fuel, located in the filter. If there is water in
the diesel fuel, the orange "Injection and pre-post heating" warning light will come on.
The system can inject diesel fuel into the engine at a pressure of up to 1600 bar. Before each operation, check that
the injector rail is depressurised and that the fuel temperature is not too high.
You must respect the cleanliness guidelines and safety advice specified in this document for any work on the high
pressure injection system.
Do not remove the internal parts of the pump and injectors. Only the flow actuator, the diesel temperature sensor
and the Venturi tube can be replaced.
For safety reasons, do not loosen high pressure pipe unions when the engine is running.
It is not possible to remove the pressure sensor from the fuel rail because this may cause circuit contamination
faults. If the pressure sensor fails, the pressure sensor, the rail and the five high pressure pipes must be replaced.
Do not remove an injection pump pulley marked with the number 070 575. If the pump needs to be replaced, replace
the pulley.
Supplying any system component directly with +12V is prohibited.
Ultrasonic decoking and cleaning are prohibited.
Never start the engine unless the battery is connected correctly.
Disconnect the injection computer when carrying out any welding work on the vehicle.
b)The connections between the vehicle's various computers are multiplexed.
The electronic system fitted in this vehicle is multiplexed. This system enables dialogue between the various vehicle
computers. As a result:
– the activation of the fault warning lights on the instrument panel is performed by the multiplex network, with the
vehicle speed sensor on the gearbox deactivated,
– vehicle faults are displayed by the multiplex network,
– the vehicle speed sensor on the gearbox is not needed.
The vehicle speed signal on the instrument panel is transmitted by the ABS computer via a wire connection, then
sent out on the multiplex network by the instrument panel. The vehicle speed signal is used mainly by the injection
computer and the airbag computer.WARNING
The engine must not operate with:
– Diesel fuel containing more than 10% diester.
– petrol, even in tiny quantities.

If regeneration whilst driving has not been possible, the driver should request After-Sales regeneration in the
following cases:
– the soot weight is greater than 56 g for Vdiag 18.
– the soot weight is greater than 59 g or the number of failed regenerations is greater than 10 for Vdiag 1C
and 20.
This regeneration is carried out in the workshop. It is essential to follow the instructions described in the
interpretation of commands SC017 Particle filter regeneration. To carry out regeneration safely (see Te c h n i c a l
Note 5040A, Recommendations for particle filter regeneration).
Warning light management:
Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature warning light or warning message;
– the level 1 fault warning light (non-critical fault),
– the level 2 fault warning light (emergency stop),
– the OBD warning light (European On Board Diagnostic),
– particle filter warning message or light.
These six functions are represented by 4 or 5 warning lights and/or messages displayed by the trip computer.
In addition, for vehicles fitted with a voice synthesiser the illumination of some warning lights may be accompanied
by a spoken message (refer to the Driver's Handbook for the vehicle concerned).
A 3 second visual inspection (automatic test procedure managed by the instrument panel) is carried out by the
injection computer when the ignition is switched on.
Orange pre-post heating/non-critical fault SERVICE warning light (level 1)
This light is used both as an in-operation indicator light and as a system fault indicator:
– Continuously lit with + after ignition feed:
Indicates plug preheating (this light goes out when preheating is complete and the engine is able to start).
– Continuously lit accompanied by the message Check injection or Electronic fault:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should carry out repairs as soon as possible. IMPORTANT
The particle filter must be replaced after a period of time which largely depends on the grade of engine oil used.
This information is provided in the vehicle's Driver's handbook.
After replacing the particle filter, it is essential to reconfigure certain parameters in the computer (see SC036
Reinitialise programming).

– Vdiag 18, 1C, 20:
This warning light or message is used to warn the driver that the particle filter is loaded with particles. This happens
when the soot weight is greater than 46 g or the number of failed regenerations is greater than:
– 8 for Vdiag 18.
– 6 for Vdiag 1C and 20.
The driver must then drive as soon as possible at an average speed of 48 mph (80 km/h) subject to the road
conditions and authorised speed limits.
EOBD management. (European On Board Diagnostic):
The OBD (On Board Diagnostic) system permits the detection of any faults relating to the vehicle emission control
system (OBD EURO IV emission control standards being exceeded).
This system should be active for the entire life of the vehicle.
1. OBD fault display conditions
An OBD fault will be detected after 3 driving cycles and the following parameters will be saved in the computer:
– engine load,
– vehicle speed
– air temperature
– coolant temperature,
– turbocharging pressure,
– rail pressure,
– air flow,
– distance travelled in miles by the vehicle since activation of the OBD warning light.
It allows the driver to know whether the vehicle has a fault directly linked to the emission control system.

2. System faults displayed by the OBD
Only a few faults are displayed by the OBD system:
– DF001 Coolant temperature sensor circuit.
– DF003 Atmospheric pressure sensor circuit.
– DF011 Sensor supply voltage no. 1.
– DF012 Sensor supply voltage no. 2.
– DF013 Sensor supply voltage no. 3.
– DF038 Computer in 6.DEF EEPROM fault.
– DF040 Cylinder 1 injector circuit in CO Open circuit.
– DF041 Cylinder 2 injector circuit in CO Open circuit.
– DF042 Cylinder 3 injector circuit in CO Open circuit.
– DF043 Cylinder 4 injector circuit in CO Open circuit.
– DF054 Turbocharging solenoid valve control circuit in CC.0 Short circuit to earth.
– DF056 Air flowmeter circuit.
– DF209 EGR valve position sensor circuit.
– DF310 Particle filter upstream temp.* sensor.
– DF315 Particle filter diff.* pressure sensor.
– DF504 Automatic transmission.
– DF621 EGR valve jammed open.
– DF717 Particle filter upstream pressure.
– DF953 Particle filter absent.
Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.
3. OBD fault clearing conditions
An OBD fault is cleared in several steps.
The fault present in the diagnostic tool will only be stored (after a repair operation) after the vehicle has been
driven 3 times.
The OBD warning light will only go out after these 3 trips.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the OBD fault and display parameters to be cleared from the computer, the system requires
40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
– the engine coolant temperature reaches at least 71.1°C,
– the engine coolant temperature varies by 22.2°C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored on the injection
computer.

COMPUTER REPLACEMENT OR REPROGRAMMING
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
– Run command SC003 Save computer data before replacing or reprogramming the computer. This enables
certain data to be saved in the diagnostic tool so that the new computer* can be reconfigured like the old one.
The saved data includes: injector codes, EGR programming, specific data for particle filter operation and vehicle
options.
– Run command SC001 Write saved data after replacing or reprogramming the computer. This command
enables the data (saved by the command SC003 Save computer data) to be rewritten in the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything.
After replacing the computer:
– Manually enter the IMA codes for each injector by reading the code on each injector (see 13B, Diesel injection,
Replacement of components, Injector replacement).
– Enter the data specific to particle filter operation by running SC036 Reinitialise programming and select After
replacing the injection computer with no save option.
Exhaust gas recirculation valve data is programmed automatically the 1st time the new computer is switched on*.
* New computer or reprogrammed computer.
Specific to the cruise control/speed limiter operation to be carried out before reprogramming of the
computer:
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.
– Position the cruise control/speed limiter switch in the rest position (the computer then detects the rest position).
– Position the cruise control/speed limiter switch in the Cruise control position to activate the Cruise control
function.
– Position the cruise control/speed limiter switch in the Speed limiter position to activate the Speed limiter function. IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Cut off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
– Wait for the engine to cool (engine coolant temperature < 60° and air temperature < 50°).
– For Vdiags 50, 58, 5C, during (re)programming of the computer, the engine fan assemblies are actuated
automatically.
– For Vdiags 18, 1C, 20, during (re)programming of the computer, the instrument panel screen displays
“Oil pressure fault”.
– Ignore this message and do not take any action in connection with it.

Before replacing or reprogramming the computer:
– Select command SC003 Save computer data,
– if the following message appears: backup file exists, do you want to overwrite it?:
(this file corresponds to the last save carried out on the tool)
–select YES.
When the backup is complete, replace the computer or reprogram, then proceed to the next step.
After replacing or reprogramming the computer:
– Select command SC001 Write saved data, then follow the instructions given by the diagnostic tool,
– if the VIN has not been entered (see "Computer identification" on the main screen), select VP010 Enter VIN,
When both these commands have finished:
–switch off the ignition and wait 1minute before switching the ignition on again,
– then check the system faults, and clear any stored faults,
– otherwise, deal with faults that are present and clear the faults in the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of operation.IMPORTANT
Thermoplunger faults are displayed during reprogramming.
– DF032 Thermoplunger 1 relay control circuit,
– DF033 Thermoplunger 2 relay control circuit,
– DF034 Thermoplunger 3 relay control circuit,
– DF238 Thermoplunger 3 relay circuit,
– DF239 Thermoplunger 2 relay circuit,
– DF240 Thermoplunger 1 relay circuit.

REPLACING OR CLEANING THE EXHAUST GAS RECIRCULATION (EGR) VALVE
After the exhaust gas recirculation valve has been replaced, the computer must store the new valve offset and the
offset measured when the ignition was last switched off, which corresponds to the valve closing.
Using this data, the computer can detect whether the valve is clogged or seized.
When the valve is replaced or cleaned, clear the stored offsets so that the program uses the new valve's offset
value.
The data linked to this strategy is compiled in the Antipollution/OBD sub-function.
– PR128 First EGR valve offset.
– PR129 Last EGR valve offset > or = PR128 for a new valve.
The PR128 and PR129 programming must be cleared every time the exhaust gas recirculation valve is replaced.
PROCEDURE:
– Run command SC036 Reinitialise programming.
–Select EGR valve as the type of operation, then follow the instructions given by the diagnostic tool.
When the command is finished,
– switch off the ignition,
–wait 1 minute before switching on the ignition again.
When the ignition is switched on again, the new EGR valve offset is automatically reprogrammed.
– start the vehicle to enable the latest EGR valve offset to be programmed,
– switch off the ignition,
–wait 1 minute before switching on the ignition again.
Reprogramming of the last EGR valve offset is stored in the computer.
– then check the system faults, and clear any stored faults,
– otherwise, deal with the faults that are present and clear the faults in the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of operation.Note:
When the reinitialisation is complete, the Emission control/OBD sub-function displays:
PR128 = PR129 > 100 %
Note:
When the new EGR valve offset has been reprogrammed, the Emission control/OBD sub-function displays:
10 % < PR128 < 40 %
PR129 > 100 %
Note:
When the last EGR valve offset has been reprogrammed, the Emission control/OBD sub-function displays:
10 % < PR128 < 40 %
10% < PR129 < 40%
