1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for
scheduled maintenance.
2. Open engine hood and check the following:
- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leaks
- Air cleaner clogging
- Gasket
3. Confirm that electrical or mechanical loads are not applied.
- Headlamp switch is OFF.
- Air conditioner switch is OFF.
- Rear window defogger switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no
load.
6. Make sure that no DTC is displayed with CONSULT-III or GST.
Is any DTC detected?
YES >> GO TO 2.
NO >> GO TO 3.
2.REPAIR OR REPLACE
Repair or replace components as necessary according to corresponding Diagnostic Procedure.
>> GO TO 3
3.CHECK TARGET IDLE SPEED
1. Run engine at about 2,000 rpm for about 2 minutes under no load.

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.
5.CHECK MAJOR LEAK IN FUEL INJECTOR/FUEL INJECTORS OPEN
Carry out TEST 6.
