3. REMINDERS
Procedure
To save energy, the UCH of the vehicle interrupts the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the
following procedure:
– Press the card unlocking button,
– insert the card in the reader,
– press the start button (interrupting the timed + after ignition feed mode),
– press the start button for more than 5 seconds, until the immobiliser warning light flashes rapidly (4 Hz).
This forced + after ignition feed mode remains active for 1 hour.
Pressing the start button or removing the card from the card reader interrupts the forced + after ignition feed, but
does not interrupt the timed forced + after ignition feed mode. As long as one hour has not elapsed, activating the
+ after ignition feed will restart forced + after ignition feed for the remaining time. Vehicle(s): Laguna II Phase 2 / Vel Satis Phase 2 /

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 the diagnostic tool is switched on
following + after ignition feed is activated (no system components 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 lines which correspond to the fault,
– the connectors on these lines (corrosion, bent pins, etc.),
– the resistance of the faulty component,
– the condition of the wires (melted or cut insulation, wear).
Conformity check
The purpose of the conformity check is to check data that does not produce a fault on the diagnostic tool if 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 repair.
The conformity check is a fault finding procedure carried out using the interpretation of statuses and parameters.
If a status does not function normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding pages (see interpretation of statuses and parameters).
Customer complaints - Fault finding chart
If the test with the diagnostic tool is correct but the customer complaint is still present, the fault should be dealt with
by customer complaints. WARNING:
Deal first with instrument panel faults (eg. "Particle filter" warning light).
Then carry out scheduled maintenance on the vehicle.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

Fuel surplus from the pump, injector return rail or rail is collected in a low pressure "octopus manifold" and is then
sent to the fuel filter, providing that the fuel is cold (recirculation), and then to the tank.
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.
Removal of the internal parts of the pump and injectors is prohibited. Only the fuel pressure regulator (or actuator)
on the high pressure pump (MPROP), the fuel pressure regulator (or actuator) on the injector rail (DRV) or the diesel
temperature sensor can be replaced.
For safety reasons, it is strictly prohibited to undo a high pressure pipe union 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, replace the pressure sensor, the rail and the high pressure pipes.
Some vehicles have a presence sensor mounted in the filter for detecting water in the diesel. If there is water in
the diesel fuel, the orange "Injection and pre-post heating" warning light will come on.
Supplying + 12 V directly to any component in the system 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 enables dialogue between the various vehicle computers. As a result:
– the fault warning lights on the instrument panel are lit by the multiplex network,
– 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 sent by the ABS computer via the multiplex network. The vehicle
speed signal is mainly used by the injection computer, the airbag computer and the automatic transmission
computer (if the vehicle is fitted with this).WARNING:
The engine must not operate with:
– Diesel fuel containing more than 10% diester,
– petrol, even in tiny quantities.
Note:
For the M9R 724 (Vdiag 5C and 58):
The engine is limited to 3000 rpm if the vehicle is stationary or if the vehicle speed is less than 4 mph (7 km/h)
and if the engine is warm.

VI - Pre-postheating actuation
Pre/postheating control involves actuating the heater plugs and the preheating indicator light on the instrument
panel (multiplex signal).
The heater plugs are actuated by a static relay.
After the ignition is switched on, a preheating delay is activated. The length of time that the warning light is lit
depends on the coolant temperature, air temperature, atmospheric pressure and battery voltage. When the coolant
temperature is below a certain threshold, a postheating function can be used to improve the combustion stability,
and consequently engine operation (reducing unburnt particles and pollutant emissions). Postheating can last up
to5 minutes.
IMPORTANT:
There are two types of heater plug: SLOW and FAST:
SLOW plugs are identified by a black ring.
FAST plugs are identified by a white ring.
The heater plugs fitted on the vehicle must be replaced with plugs of the same type; otherwise there is
a risk of the heater plugs deteriorating which could lead to engine destruction.
Only Vdiag 20, 24, 38 and 74:
when replacing heater plugs with plugs which differ from those currently fitted on the vehicle (replacement of
SLOW plugs with FAST plugs), the computer must be configured (see Replacement of components, Replacing
heater plugs) by running command SC036 Reinitialise programming and selecting Heater plugs if this choice
is available, then following the procedure.

Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This concerns five
functions:
– the pre-postheating warning light,
– the coolant temperature warning light,
–the level 1 fault warning light (non-critical fault),
–the level 2 fault warning light (emergency stop),
–the EOBD (European On Board Diagnostic) warning light,
These six functions are represented by 3 warning lights and/or messages displayed by the on-board computer.
Orange pre-post heating/non-critical fault SERVICE warning light (severity 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 preheating of the spark plugs.
– Continuously lit with the Check injection message:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should have the repairs carried out as soon as possible.
Temperature / red emergency STOP warning light (level 2)
This indicator light is used both as an in-operation indicator light and as a system fault warning light. It lights up for
3 seconds after the ignition is switched on (automatic test procedure managed by the instrument panel):
– Continuously lit:
Indicates engine overheating (the driver is free to choose whether or not to stop the vehicle).
– Continuously lit with the faulty injection message:
Indicates a level 2 fault (In this case, the injection is automatically cut after a few seconds).
The driver should carry out repairs as soon as possible.
ORANGE Excessive pollution EOBD warning light
Symbolised by an engine, it lights up for approximately 3 seconds when the ignition is switched on.
This warning light comes on if the system has one or more EOBD faults.
This warning light is used to alert the driver to injection faults that could lead to excessive pollution, or if the EOBD
system (European On Board Diagnostic) has been deactivated.
The injection computer requests illumination of the EOBD warning light for a present fault only after three
consecutive driving cycles.
The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the
instrument panel) is carried out by the injection computer.
Special particle filter ORANGE warning light or warning message (depending on instrument panel)
Only for Vdiag: 18, 1C, 54, 20, 58, 5C, 24, 26 and 60.
This warning light or message is used to warn the driver that the particle filter is loaded with particles, (see the soot
weight thresholds for illumination of the warning light for fault DF312 Speed request) due to driving conditions which
were not suitable for regeneration to take place. 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, until the warning light goes out.

EOBD management (European On Board Diagnostic):
The EOBD system enables the detection of any faults relating to the vehicle emission control system
(EOBD EURO IV emission control standards exceeded).
This system should be active for the entire life of the vehicle.
1. Conditions for an EOBD fault appearing
An EOBD fault will be detected after 3 driving cycles.
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 EOBD
Only a few faults are indicated by the EOBD system:
– DF002 Air temperature sensor circuit.
– DF004 Turbocharging pressure sensor circuit.
– DF011 Sensor feed voltage no. 1.
– DF012 Sensor feed voltage no. 2.
– DF013 Sensor feed voltage no. 3.
– DF026 Cylinder 1 injector control circuit.
– DF027 Cylinder 2 injector control circuit.
– DF028 Cylinder 3 injector control circuit.
– DF029 Cylinder 4 injector control circuit.
– DF054 Turbocharging solenoid valve control circuit.
– DF056 Air flow sensor circuit.
– DF107 Computer memory.
– DF200 Atmospheric pressure sensor.
– DF209 EGR position sensor circuit.
– DF272 EGR valve control circuit.
– DF569 Turbocharging circuit.
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. Conditions for clearing an EOBD fault
An EOBD fault is cleared in several phases.
The fault present in the diagnostic tool will only be stored (following repair) after the vehicle has been driven
3times.
The EOBD warning light will only go out after these 3 driving cycles.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the EOBD fault and display parameters to be cleared from the computer, the system must go
through 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 EOBD fault will still be present or stored in the injection
computer.
