DTC CONFIRMATION PROCEDURE

CAUTION:

If “

EC-413, "Diagnosis Procedure"

” is unfinished, be sure to perform Step 3 and 4.

1.

PRECONDITIONING-1

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.

TEST CONDITION:

Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 2.

2.

PRECONDITIONING-2

Is “Diagnosis Procedure” of DTC P0524 finished?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and warm it up to normal operating temperature.

2. Maintain the following conditions for about 10 consecutive seconds.

NOTE:

With engine speed set around 4,000 rpm, the phenomenon can be reproduced more easily.

3. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-413, "Diagnosis Procedure"

.

NO

>> INSPECTION END

4.

CHECK ENGINE OIL LEVEL

Check engine oil pressure. Refer to 

LU-9, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Proceed to 

EC-413, "Diagnosis Procedure"

.

5.

CHECK ENGINE OIL PRESSURE

With CONSULT

DTC No.
