PRESENT
OR
STOREDRAIL PRESSURE REGULATION FUNCTION1.DEF: Above maximum threshold.
2.DEF: Negative loop deviation.
3.DEF: Positive loop deviation.
4.DEF: Below minimum threshold.
NOTESOrder of priority for a combination of faults:
Deal with fault DF643 Rail pressure regulator circuit first if it is present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started,
– a road test.
Special notes:
If the fault is present:
– engine torque limited for 2.DEF/3.DEF,
–the level 1 warning light comes on for 2DEF/3.DEF.
–the level 2 warning light comes on for 1.DEF/3.DEF/4.DEF,
– engine stops for 1.DEF/3.DEF/4.DEF.
Use bornier Elé.1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

In the event of rail overpressure:
Check the operation of the injectors (see Test 10 Incorrect injector operation).
Display parameter PR038 Rail pressure and refer to the conformity check to check the conformity of the operating
values.
If these checks do not indicate any abnormality and if the fault persists, replace the injection pump.
In the event of rail vacuum pressure:
Check that the rail pressure sensor is operating correctly using command AC011 Rail pressure regulator. Display
parameter PR038 Rail pressure and refer to the conformity check to check the conformity of the operating values.
Check the priming of the low-pressure diesel circuit.
Check the conformity of the diesel filter connections.
Check the condition of the filter (clogging and water saturation).
Check that there are no air bubbles between the filter and the high pressure pump.
Check the seal of the low and high pressure diesel circuits (visual checks, odour, etc.), pump body, overpressure
valve, pipes, rail and injector unions, injector wells, etc.
Check the operation of the injectors (see Test 10 Incorrect injector operation).
Carry out the necessary operations.
If the fault is still present, replace the injection pump.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

PARAMETER
DEFINITIONThis parameter indicates the turbocharger pressure opening cyclic ratio in %.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Engine running, engine coolant temperature > 80°C
The value must be between 35 < PR048 < 45%
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Engine stopped, ignition on
The value should be: PR048 = 15%
In the event of a fault, consult the interpretation of faults DF007 Rail pressure sensor circuit and DF053 Rail
pressure regulation function.
