NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

 The DTC becomes present after the engine is started.

• If the DTC is present:
- Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000001162567

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. 

DTC No.
