–Apply ALP6 Fuel circuit leaks.
–Apply Test 3 Low pressure circuit check.
– Replace the high pressure pump.
Check 2:
–Apply Test 10.
–Apply ALP6.
– Apply the part of Test 3 concerning the fuel filter.
– Replace the high pressure pump.
– Check the injector return flow and the injectors.
– Check the rail pressure regulator by running command AC225 Rail pressure regulator.

STEP 2
In the event of rail overpressure:
Check that there are no air bubbles in the diesel fuel low pressure circuit.
Check that the rail pressure sensor is working, and then interpret parameter PR038 Rail pressure.
If these checks do not reveal any faults, replace the rail regulator.
in the event of rail underpressure:
Check the correct operation of the rail pressure sensor, as well as the interpretation of parameter PR038.
Check the low pressure diesel circuit priming.
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 sealing of the low and high pressure diesel fuel systems: use ALP6 Fuel circuit leaks (visual
inspections, touch tests, odours, etc.) on:
pump body, pressure release valve, pipes, rail and injectors unions, injector wells, etc.
Check the conformity of the seal fitting on the pressure regulator.
Check the operation of the injectors: run Test 10 Incorrect injector operation.
Carry out the necessary repairs.
If the engine starts:
Clear any faults.
Check the rail pressure regulator using ALP7 Rough idling.
With the engine warm, leave it to idle for a few minutes (3 to 5 minutes):
– If it stalls and the fault reappears, replace the rail pressure regulator.
– If it does not stall, stabilise the engine speed at 2000 rpm (1 minute) then depress the accelerator fully until the
maximum engine speed imposed by the computer is obtained (~5500 rpm). The maximum rotation speed of the
engine must be stabilised in the time taken to fully depress and then fully release the pedal. This test is carried
out with no load (engine in neutral).
– If the engine stalls, contact the Techline
If the engine does not start or there is no timing, first replace the rail pressure regulator.
If the fault is still present, contact the Techline

Is the engine running on all cylinders?
Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
Check that the fuel tank is correctly filled and that the fuel is correct: run Test 12 Diesel fuel conformity check.
If the fuel (diesel fuel) used is not correct:
– Replace the fuel (diesel fuel).
– Replace the fuel filter (diesel fuel).
– Bleed the low and high pressure fuel circuit (diesel fuel).
Check that the injectors are correctly fitted (presence and conformity of the sealing washer).
– Checking procedure:
– Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
– If one or more injector(s) are not in order, remove and check the conformity of the washer.
– If one injector does not touch the straightedge (clearance of more than 1mm), remove the injector and check
that the washer is present.
Clean the injector well and the injector, refit the injector with the correct sealing washer.
Check the sealing and the condition of the inlet circuit: run Test 4 Turbocharged air inlet circuit check.
Check the condition of the air flowmeter: run Test 5 Air flowmeter.
Check the turbocharger: run Test 7 Variable geometry turbocharger control then Test 8 Turbocharger
