DTC CONFIRMATION PROCEDURE

1.

PERFORM DIAGNOSIS PROCEDURE

NOTE:
DTC P0002 can not duplicate.

>> Proceed to 

EC9-185, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010309087

1.

CHECK FUEL LEVEL

Check that the fuel level is enough.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Refuel.

2.

PERFORM FUEL FILTER AIR BLEEDING

NOTE:
If the DTC is detected because of air mixed with fuel (i.e.; caused by lack of fuel), it may become nor-
mal by performing following procedure.
1.

Turn ignition switch ON.

2.

Perform fuel filter air bleeding. Refer to 

FL-47, "Air Bleeding"

.

3.

Erase DTC.

4.

Perform DTC confirmation procedure again. Refer to 

EC9-185, "DTC Logic"

.

Is the DTC P0002 detected again?

YES

>> GO TO 3.

NO

>> INSPECTION END

3.

CHECK FUEL FILTER

Check the correctness of the fuel filter.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace error-detected parts.

DTC No.
