ALP 14 Overspeed at idle speed or on releasing brake
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check the engine oil grade and level.
Check the injection computer: that the connections and wiring are in good condition, that earths and feeds are
present.
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Using the CLIP diagnostic tool, carry out a multiplex network test (see 88B, Multiplexing).
Using the CLIP diagnostic tool, check the ABS computer (see 38C, Anti-lock braking system).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 1 Low pressure fuel supply system check
NOTESCauses:
Fuel is present in the transparent supply pipe leading to the pump, or large air bubbles
can be seen (small bubbles are permitted).
The engine does not start.
Check the conformity and presence of fuel by running Test 13: Diesel fuel conformity check.
Bleed the fuel supply system with the manual priming pump.
Does the fuel flow correctly when pumped
manually?
NO
Check that there are no leaks in the supply and
return pipes and check that they are in good
condition and installed correctly.
Check the cleanliness of the fuel filter.
Remove the fuel sender and check for leaks.
Check that the fuel sender strainer is not
blocked.
YESLow pressure fuel supply system correct.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 8 Particle filter injector supply circuit check
NOTESDeal first with faults DF991 Particle filter injector control circuit and DF1004
Electric fuel pump relay control circuit.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Vdiag 45, 49 and 4D only.
Check the condition of the fuel supply pipes
between the particle filter injector and the electric
fuel pump.
Check that the pipes are not trapped, blocked or
pierced and there that are no leaks.
Are the components in good condition?
YES
Check the particle filter injector, component
code 1750.
Check the condition, power feed and
connections of the particle filter injector.
(Consult the interpretation of fault DF991
Particle filter injector control circuit). Check it
works by running command AC238 Particle
filter injector.
Does the particle filter injector operate
correctly?
YES
NOReplace any faulty components.
NOReplace the particle filter injector if
necessary.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
