VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.

ALP5 Irregular engine operation
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
If the engine races during gear changes, if there is a floor carpet, check that this is not blocking the accelerator
pedal, the brake pedal and the clutch pedal, then check the conformity of the clutch switch and the conformity of
the accelerator pedal sensor when the pedal is released.
Measure the resistance of the engine speed sensor between the following connections:
– Connection code 3BG,
– Connection code 3BL,
of component 149.
Replace the sensor if the resistance is not 200 Ω to 270 Ω at +20°C
Check the continuity of the following connections:
– Connection code 3BG,
– Connection code 3BL,
between components120 and 149.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting and condition (overheating) of the sensor.
Replace if necessary.
Check the low pressure circuit, run test 3 Low pressure circuit check.
Apply the air flow test procedure (see Interpretation of statuses and Interpretation of parameters).
Check the turbocharger, apply the following tests:
– test 2: Air path at the turbocharger,
– test 6: Turbocharger control solenoid valve check,
– test 7: Turbocharger.
Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).

ALP11 Particle filter warning light comes on too often
NOTESThis ALP is specific to Vdiag48.
Before dealing with this customer complaint, check that there are no faults
except DF312 Speed request, and check the conformity (or otherwise) of the
"parameters" and "statuses" using the diagnostic tool. Deal with the other faults
first.
If the customer complaint is not eliminated, perform the following checks.
Have the last 10 regeneration attempts failed?
Is the mileage of PR412 Mileage of last successful
regeneration less than all the parameters of group 2? (PR794
to PR803 Stored regeneration failure no. 1 to no. 10)Is at least one status in group 1
= STATUS4?
Symptom not
confirmed
Are all the regeneration failures linked to engine cut-off?
See parameter ET706 Stored engine status no.1 to ET715
Stored engine status no.10 (E.g. ET706 STOPPED)
Check the exhaust pipe for leaks or blockage. Repair if
necessary.

TEST3 Low pressure circuit check
HIGH PRESSURE PUMP
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter),
– positioning and clogging condition of the filter cartridge,
– Positioning and condition of the seals.
– if there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
●Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely with
an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and seal it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container of approximately 5litres.
– Disconnect the diesel return pipe at the diesel temperature sensor (pump return and injector return join), and block
it using a plug.
– Connect a transparent pipe to the union of the diesel temperature sensor, and insert the other end in the container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect
the various pipes of the low pressure circuit and
repeat the fault finding chart fault finding or of
the fault that referred you to this test.

Check the condition and operation of the priming bulb.
Perform repairs if necessary and continue the test.
Check the condition of all the low pressure diesel pipes from the tank to the injection pump (in particular no pinching
of pipes).
If the fault is still present with a low fuel level, check the consistency of the actual fuel level and that indicated on
the instrument panel.
– The transfer pump is supplied via a Venturi pipe mounted underneath it.
Check that the opening of the venturi (6 to 8 mm in diameter) is not blocked by dirt contained in the fuel tank.
Check the priming of the low pressure diesel circuit.
Check the conformity of the fuel used by running test 11 Diesel fuel conformity check:
– Compare the fuel with some clean diesel in order to detect petrol, solvent, thinners, sulphuric acid (fuel will have
a whitish appearance), water or fuel oil.
If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low and high pressure diesel circuit.
Low pressure circuit correct.

Check:
– The condition and fitting of the ducts (foreign bodies, clogged, displaced, kinked, broken, pierced, cut, tightness
of the mounting bolts, etc.).
– the presence, condition and fitting of the seals,
– the presence and tightening of the clamps,
– the fitting of the turbocharger pressure sensor.
– the pipe and take-off point between the air duct and the turbocharging sensor
Carry out the necessary repairs
Checking the air filter.
Check:

Note: the operating play in the EGR heat exchanger valve shaft produces small black marks due to a slight leak
of no importance. Do not replace this part.
Replace if necessary.
