4. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK ENGINE CONDITION
Start engine.
Is the engine start?
YES >> GO TO 7.
NO >> GO TO 9.
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.

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.

6.CHECK ENGINE CONDITION
 Check that the oil level is correct and that the engine coolant temperature is normal operation tempera-
ture.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.

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.
2. Check that the “FUEL TEMP” indication when operating at idle speed is between 60 - 80°C (140 - 176°F)
3. Check that the “WATER TEMP” indication is between 80 - 90°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 HIGH PRESSURE SUPPLY PUMP (VOLUMETRIC CONTROL VALVE) POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect high pressure supply pump (volumetric control valve) harness connector.
3. Turn ignition switch ON.
4. 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)
 Harness for open or short between IPDM E/R and high pressure supply pump (volumetric control valve)
>> Repair open circuit or short to ground or short to power in harness or connectors.
10.CHECK HIGH PRESSURE SUPPLY PUMP (VOLUMETRIC CONTROL VALVE) OUTPUT SIGNAL CIR-
CUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
