DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING-1

If DTC Confirmation Procedure is previously conducted, always perform the following procedure before con-

ducting 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, check that battery voltage is 9 V or more with ignition

switch ON.

>> GO TO 2.

2.

PRECONDITIONING-2

NOTE:

• When it is certain that the previous driving is performed with the engine warmed up, the next steps can be

performed.

• When it is difficult to satisfy the conditions, performing Component Function Check can identify the presence

or absence of malfunction in the part/system that may result in a possible cause of this DTC. (Perform DTC

Confirmation Procedure as much as possible.)

1. Start the engine and warm it up until engine coolant temperature reaches 70

°C (158°F) or more.

2. Stop the engine and leave the vehicle in a cool place (soak the engine) until the engine coolant tempera-

ture reaches 35

°C (95°F) or less.

CAUTION:

• The difference between air temperature and engine coolant temperature must be 5

°C (9°F) or less.

• Never turn ignition switch ON during soak the engine.

DTC No.

SE”.

3. Check that the indicated value of “COOLAN TEMP/S” is less than 35

°C (95°F).

4. Check that the difference between “INT/A TEMP SE” and “COOLAN TEMP/S” is 5

°C (9°F) or less.

5. Check “Self-diagnostic result” of “ENGINE”.
Is the DTC detected?

YES

>> Proceed to

EC-438, "Diagnosis Procedure"

.

NO-1 (Conditions satisfied)>>GO TO 5.

NO-2 (Conditions not satisfied)>>GO TO 2.

5.

PERFORM DTC CONFIRMATION PROCEDURE-2

1. Start the engine (or cranking) at least 1 second.

2. Check “Self-diagnostic result” of “ENGINE”.
Is the DTC detected?

YES

>> Proceed to

EC-438, "Diagnosis Procedure"

.

NO-1 >> To check malfunction symptom before repair: Refer to

GI-45, "Intermittent Incident"

.

NO-2 >> Confirmation after repair: INSPECTION END
