DTC Description

INFOID:0000000010775227

This diagnosis result is detected when the fuel level of the fuel tank is extremely low and the engine does
notrun normally.

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Fuel cut
• Harness or connectors (Fuel pump circuit is open or shorted.)
• Fuel pump
• Fuel pressure regulator
• Fuel pump system
• Harness or connectors (High pressure fuel pump circuit is open or shorted.)
• High pressure fuel pump
• High pressure fuel pump system
• Fuel rail pressure sensor
• Hose disconnection

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE-1

Start the engine.

Does the engine start?

YES

>> GO TO 3.

NO

>> Proceed to

EC-332, "Diagnosis Procedure"

.

3.

PERFORM DTC CONFIRMATION PROCEDURE-2

1.

Start engine and warm it up to normal operating temperature.
NOTE:
For best results, warm up the engine until “COOLAN TEMP/S” on “DATA MONITOR” mode of “ENGINE”
using CONSULT reaches at least 70

°

C (158

°

F).

DTC No.
