BASIC INSPECTION : Description
INFOID:0000000001162514
NOTE:
Only consult the tests after following the diagnostic procedure chart.
Some specific checks are grouped under the “tests” heading and are used as required in different diagnostic
charts.
BASIC INSPECTION : Special Repair Requirement (TEST 1: Low Pressure Fuel Sup-
ply System Check)
INFOID:0000000001162515
NOTE:
• CAUSE
- No fuel can be seen in the transparent supply pipe leading to the pump or large air bubbles can be seen
(small air bubbles are permitted).
- engine does not start.
1.
CHECK CONFORMITY
Check the conformity and presence of the fuel (gasoline instead of diesel, contaminated fuel).
Is the inspection result normal?
Yes
>> GO TO 2.
No
>> Bleed the fuel supply system with the manual priming pump.

INSPECTION AND ADJUSTMENT
2.
CHECK FUEL CIRCUIT
Does the fuel circulate correctly when pumped manually?
Yes or No
Yes
>> GO TO 5.
No
>> GO TO 3.
3.
CHECK FOR LEAK
Look for leaks on the unions.
Are there leaks in the hoses and unions?
Yes
>> Carry out the required repairs.
No
>> GO TO 4.
4.
CHECK FUEL FILTER
Check the correctness of the fuel filter.
Is the fuel filter correct?
Yes
>> GO TO 5.
No
>> Replace the fuel filter with a genuine part.
5.
INSPECTION END
Low pressure circuit OK.
>> INSPECTION END
BASIC INSPECTION : Special Repair Requirement (TEST 2: Internal Fuel Transfer
Pump Check)
INFOID:0000000001162516
NOTE:
• CONDITIONS PRIOR TO TEST
- Test 1 Low pressure fuel supply system check has been carried out previously and results are satisfactory.
• CAUSE
- Fuel can be seen in the transparent supply pipe leading to the pump.
- However, fuel does not move during starting.
1.
CHECK INTERNAL FUEL TRANSFER PUMP
1.
Disconnect high pressure supply pump (volumetric control valve) harness connector
2.
Remove fuel return pipe from the pump and block it so that it is sealed. Connect a pipe to the pump to
measure the flow of diesel.
3.
To authorise a 15 second cranking engine and carry out this test it is essential to carry out the following
procedure: measure the flow of diesel.
-
Turn ignition switch ON.
-
Perform “SAVE DATA FOR CPU REPLC” in WORK SUPPORT mode with CONSULT-III.
-
Perform “PRGRM REINITIALIZE” in WORK SUPPORT mode with CONSULT-III.
-
Cranking engine for at least 15 seconds (starting speed 250 rpm)
-
Check the flow rate of the fuel being collected in a graduated measuring cylinder (500 ml minimum).The
minimum flow rate must be 25 ml every 15 sec.
-
Perform “WRT DATA AFTR REPLC CPU” in WORK SUPPORT mode with CONSULT-III.
Does the flow measure less than 25ml?
Yes
>> Replace high pressure supply pump.
No
>> GO TO 2.
2.
INSPECTION END
Low pressure system OK.

Pump (Pressure Control Valve) Check]
INFOID:0000000001162517
NOTE:
• CONDITIONS PRIOR TO TEST
- The entire low pressure system must be in good condition.
- Check the sealing of the high pressure pipes and unions.
• CAUSE
- Rail pressure approximately 5000 kPa(50 bar, 51 kg/cm
2
, 725 psi) during starting.
1.
CHECK HIGH PRESSURE SUPPLY PUMP (PRESSURE CONTROL VALVE) POWER SUPPLY
1.
Turn ignition switch OFF.
2.
Disconnect high pressure supply pump (pressure control valve) harness connector.
3.
Turn ignition switch ON.
4.
Check the voltage between high pressure supply pump (pressure control valve) harness connector and
ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
DETECT MALFUNCTIONING PART
Check the following.
• IPDM E/R
• Harness for open or short between IPDM E/R and high pressure supply pump (pressure control valve)
• Harness for open or short between ECM and high pressure supply pump (pressure control valve)
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.
CHECK HIGH PRESSURE SUPPLY PUMP (PRESSURE CONTROL VALVE) OUTPUT SIGNAL CIRCUIT
FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check the continuity between high pressure supply pump (pressure control valve) harness connector and
ECM harness connector.
4.
Also check harness for short to ground and short to power.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
HIGH PRESSURE SUPPLY PUMP (PRESSURE CONTROL VALVE) CHECK
EC-1123, "Component Inspection"
.
Is the inspection result normal?
Yes
>> INSPECTION END
No
>> Replace high pressure supply pump.
