• Does “RAIL PRESSURER” follow “RAIL PRES SET” when the cranking engine.
NOTE:
If the rail pressure does not reach the setpoint there is an fuel injector leak that is too great or the pressure sig-
nal is incorrect.

Is the inspection result normal?

YES

>> GO TO 11.

NO

>> GO TO 10.

BASIC INSPECTION : Special Repair Requirement (TEST 5: Rail High Pressure Reg-
ulation Check)

INFOID:0000000001162519

NOTE:
• If contaminants (swarf) can be seen in the transparent return pipe, the entire fuel injection system (fuel injec-

tors, pump, rail, high pressure pipes and all return pipes) must be replaced.

• CONDITIONS PRIOR TO TEST
- Engine coolant temperature between 80 - 90

°

C (176 - 194

°

F).

- All the electrical load are switched off.
- Air conditioning is switched off.
- The tank is at least half-full.
- The pipe connections and unions have been checked.
- Check the sealing of the high pressure pipes and unions.
• CAUSE
- Rail pressure variations around the setpoint.
- The rail reference pressure is not reached.
- Rough idle.
- Possibly noisy combustion.

1.

Does the engine stop?

YES

>> GO TO 3.

NO

>> Replace high pressure supply pump (the high pressure supply pump [volumetric control valve]

remains open mechanically).

3.

CHECK HIGH PRESSURE SUPPLY PUMP (PRESSURE CONTROL VALVE)-I

1.

Reconnect high pressure supply pump (volumetric control valve) harness connector.

2.

Wait at least 30 seconds.

3.

Start engine and let it idle speed.

4.

Select “DATA MONITOR” mode with CONSULT-III.

5.

Check that the “F/FLOW CORR CYL1”, “F/FLOW CORR CYL2”, “F/FLOW CORR CYL3”, “F/FLOW
