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.

Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

NOTESSpecial notes:
– Use bornier Elé. 1681 for all operations on the engine management computer
connectors.
–Do not clear the fault before reading the contexts of the fault.
(see Wiring diagram Technical Note for Mégane II ph2, Scénic II ph2,
Espace IV ph2)
Conditions for applying the fault finding procedure to a stored fault:
– The fault is declared present if the EOBD (European On Board Diagnostic)
warning light is lit.
Check the multiplex network.
Check the condition of the automatic transmission computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Espace IV ph2, component code 119).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Espace IV ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation to earth, the continuity and absence of interference resistance on the following
connections:
•3MT between components 119 and 120,
•3MS between components 119 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, check that the automatic transmission computer is recognised by the CLIP diagnostic
tool.
If dialogue is not established (see MR 366, 372, 407, 23A, Automatic transmission).

PRESENTThere is a multiplex connection between the injection computer and the automatic
transmission computer.
ABSENTThere is no multiplex connection between the injection computer and the automatic
transmission computer, as there is a manual gearbox.
If there is an automatic transmission and the message ABSENT appears:
Run a multiplex network test (see 88B, Multiplex).
Check the continuity and insulation to earth of the following connections:
•3MS and 3MT between components 119 and 120.

If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active
(ET042 Cruise control / speed limiter: CRUISE CONTROL) and traction control is

(ET042: CRUISE CONTROL) and brake pedal depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command

The cruise control function is deactivated when the gearbox is not coupled to
the engine (clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with the cruise control active
(ET042 Cruise control / speed limiter: CRUISE CONTROL) and the clutch pedal is
depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405 Clutch pedal switch.
If the vehicle is fitted with an automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation
to the vehicle's technical specification, especially the configuration of the automatic

STATUS 5
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 changes to STATUS 5, deal with present faults or those stored in
the injection computer.
If the fault is still present, contact the Techline.
STATUS 6Gear lever in neutral (manual gearbox) or neutral (automatic gearbox)
Status ET415 changes to STATUS 6, when driving, with cruise control active (ET042:
CRUISE CONTROL) and:
– if the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is put in neutral on an automatic transmission.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on
a manual gearbox without declutching, or into the neutral position on an automatic
transmission, run fault finding on the ABS computer and check the configuration of the
tyre size stored in the computer. If the configuration is correct, contact the Techline.

STATUS 7
Lack of correlation between the request and the vehicle speed
Status ET415 becomes STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
This could occur when driving with the cruise control active (ET042 Cruise control /
speed limiter: CRUISE CONTROL) on very steep terrain.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 7 where the surface is not uneven, contact the
Techline.
STATUS 8Automatic gearbox in defect mode.
Status ET415 becomes STATUS 8, when driving with cruise control active
(ET042: CRUISE CONTROL) and if the automatic transmission is in defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission).
Clear the automatic transmission computer memory by running command RZ001.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If STATUS 8 is still present, contact the Techline.
