- Record DTC and freeze frame data. (Print them out with CONSULT-III or GST.)
- Erase DTC. (Refer to EC-94, "
Diagnosis Description".)
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to EC-366, "
Symptom Table".)

Is any symptom described and is any DTC detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.
3.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer (except MI ON).
Also study the normal operation and fail safe related to the symptom. Refer to EC-370, "
Description" and EC-
358, "FailSafe".
Diagnosis Work Sheet is useful to verify the incident.

5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC CONFIRMATION PROCEDURE for the displayed DTC, and then make sure that DTC is
detected again.
If two or more DTCs are detected, refer to EC-360, "

diagnosis order.

Freeze frame data is useful if the DTC is not detected.
Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service
Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.

DTCIndex".
