Check the low pressure circuit using Test 3 Low pressure circuit test and check that there are no exterior air
leaks in the low pressure fuel circuit.
Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
If the fault is still present, check the rail pressure regulator connections (DRV).
check the engine management computer connections.
Check the seal on the rail pressure regulator (DRV):
Disconnect the low-pressure return pipe from the rail pressure regulator (DRV). In its place, connect a transparent
pipe, with the other end leading to a container of some sort in order to collect the drained diesel fuel.
Start the engine and let the engine idle.
When the engine is started, no diesel should flow into the transparent pipe as the rail pressure regulator (DRV) is
closed so that the pressure in the hydraulic system can rise.
Diesel fuel should flow into the transparent pipe a few seconds after the engine is started, provided that the diesel
is cold (less than 15°C), as the regulation is provided by the rail pressure regulator (DRV).
If the diesel is warm (above 15°C), regulation is controlled by the pump pressure regulator (MPROP). No diesel
should flow into the pipe.
