7.
CHECK ENGINE CONDITION
• Check that the oil level is correct and that the engine coolant temperature is normal operation temperature
60
°
C (140
°
F)
• Engine running at idle speed.
- Select “HIGH PRES CIRCUIT LEAK TEST” in “ACTIVE TEST” mode with CONSULT-III.
- Engine will perform 4 acceleration cycles.
- Select “DATA MONITOR” mode with CONSULT-III.
- Check that the “RAIL PRES SET” and “RAIL PRESSURE” indication.

±
5000 kPa(50 bar, 51 kg/cm
2
, 725 psi) during the
phase of the 4 acceleration cycles?
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 8.
8.
CHECK RAIL HIGH PRESSURE CONTROL CIRCUIT
Carry out TEST 5.
>> GO TO 11.
9.
CHECK ENGINE CONDITION
• Check that the oil level is correct.
• Select “DATA MONITOR” mode with CONSULT-III.
• Check that the “RAIL PRES SET” and “RAIL PRESSURE” indication.
• 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.
10.
CHECK MAJOR LEAK IN FUEL INJECTOR/FUEL INJECTORS OPEN
Carry out TEST 6.
>> GO TO 11.

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.
CHECK AIR BUBBLES
1.
Start engine
2.
Are there large air bubbles in the transparent supply pipe going to the pump?
Is the inspection result normal?
YES
>> Check low pressure system.
NO
>> GO TO 2.
2.
CHECK HIGH PRESSURE SUPPLY PUMP (VOLUMETRIC CONTROL VALVE)-I
Disconnect high pressure supply pump (volumetric control valve) harness connector.
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.
Turn ignition switch OFF and wait at least 30 seconds.
3.
Start engine.
4.
Disconnect high pressure supply pump (pressure control valve) harness connector.
Does the engine stop?
YES
>> GO TO 4.
NO
>> Replace high pressure supply pump (the high pressure supply pump [pressure control valve]
remains open mechanically).
4.
CHECK FUEL INJECTOR
1.
Reconnect high pressure supply pump (pressure 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
CORR CYL4” indication.
Are the reference value 0.3 - 1.9?
YES
>> GO TO 6.
NO
>> GO TO 5.

Is the inspection result normal?
YES
>> GO TO 22.
NO
>> GO TO 7.
7.
CHECK ENGINE COOLANT TEMPERATURE AND FUEL TEMPERATURE
1.
Select “DATA MONITOR” mode with CONSULT-III.

Check that the “FUEL TEMP” indication when operating at idle speed is between 60 - 80
°
C (140 - 176
°
F)

°
C (176 - 194
°
F)
NOTE:
• When the fuel temperature is above 136
°
C (277
°
F), the maximum rail pressure is reduced to protect the
plastic pipes.
• When the coolant temperature is above 100
°
C (212
°
F), the maximum rail pressure is reduced to protect the
engine.
Are the “FUEL TEMP” and “WATER TEMP” within the reference value range?
YES
>> GO TO 8.
NO
>> Check the fuel pump temperature sensor (Refer to
EC-1137, "Component Inspection"
) or engine
coolant temperature sensor (Refer to
EC-1133, "Component Inspection"
8.

Check the voltage between high pressure supply pump (volumetric control valve) harness connector and
ground.
Is the inspection result normal?
YES
>> GO TO 10.
NO
>> GO TO 9.
9.
DETECT MALFUNCTIONING PART
Check the following.
• IPDM E/R
• Harness for open or short between ECM and high pressure supply pump (volumetric control valve)
