Conformity check with engine stopped and ignition on
INACTIVE
Conformity check with engine running, engine coolant temperature > 80 °C
– Engine stopped.
ACTIVEIf the status is ACTIVE, consult the interpretation of fault DF773 Pressure regulator
circuit.

– Engine under load.
ACTIVEThe status is ACTIVE under low engine loads or when the engine is running at idle
speed.
If the status is INACTIVE with the engine at idle speed, consult the interpretation of fault

FUEL FLOW REGULATOR
STATUS DEFINITIONINACTIVE: This status indicates that the fuel pressure regulator is INACTIVE.
ACTIVE: This status indicates that the fuel pressure regulator is ACTIVE.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
This solenoid valve regulates the flow of fuel entering the high pressure pump and enables an optimum quantity
of fuel to be pressurised according to operating phase; this improves the output of the Common Rail pump and
thereby the output of the engine as well.
Conformity check with engine stopped and ignition on
ACTIVE
Conformity check with engine running, engine coolant temperature > 80 °C
If the status is ACTIVE, consult the interpretation of fault DF770 Flow regulator
circuit.
INACTIVE– Engine stopped.
– Engine running at idle speed.
ACTIVEThe status is ACTIVE when there is a high engine load.
If the status is INACTIVE with the engine at idle speed, consult the interpretation of fault
DF770 Flow regulator circuit.
INACTIVE– Engine running at idle speed.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

temperature > 80°C
INACTIVE
The fan assembly is inactive when the coolant temperature does not exceed 96°C.
LOW SPEEDThe injection computer requests the activation of the low speed GMV when:
– the engine coolant temperature is above 96°C,
– the injection computer has system faults that could lead to the engine
overheating,
– the air conditioning is switched on by the driver.
When the high speed fan is supplied:
–status ET022 Low speed fan request becomes activated.
The low-speed fan assembly stops when:
– the engine coolant temperature is below 94°C,
– no fault which could cause engine overheating is present in the injection
system.
– the air conditioning is not switched on by the driver.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

JAMMED ACCELERATOR PEDAL
STATUS DEFINITIONYES: This status indicates that the accelerator pedal is detected to be jammed.
NO: This status indicates that the accelerator pedal is not detected to be jammed.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant

Apply this procedure only if the status is YES.
Use the Wiring Diagram Technical Note for Mégane II ph2, Scénic II ph2, CLIO III,
MODUS and Kangoo II.
Check the condition of the connector for the brake switch, component code160.
Check the condition of the connector for the accelerator potentiometer, component code921.
Check the condition of the connector for the engine management computer, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Measure the resistance of the pedal potentiometer gang 1 between connections 3LR and 3LT.
If the resistance of the pedal potentiometer is not between 0.8 kΩ and
2.6 kΩ, replace the pedal potentiometer
(see MR 392, 385, 364, 370 and 417 Mechanical, 13B, Diesel injection, Accelerator pedal potentiometer:
Removal - Refitting).
Measure the resistance of the pedal potentiometer on gang 2 between connections 3LU and 3LV.
If the resistance of the pedal potentiometer is not between 0.8 kΩ and
4.9 kΩ, replace the pedal potentiometer
(see MR 392, 385, 364, 370 and 417 Mechanical, 13B, Diesel injection, Accelerator pedal potentiometer:
Removal - Refitting).
YES or NOThis status varies when the ignition is on or the engine is running depending on the
status of the accelerator pedal.
