Diagnosis Procedure
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.
• Harness or connectors E8, F1 • Harness for open or short between IPDM E/R 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
Refer to EC-900, "Component Inspection".
Is the inspection result normal? Yes >> GO TO 5.
No >> Replace high pressure supply pump.
5.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident", ???INCIDENT SIMULATION TESTS??? and ???GROUND INSPECTION???.
>> INSPECTIO END
