when the incident/malfunction occurred) using the “Diagnostic Work Sheet”. (Refer to 

EC-134, "Diagnostic

Work Sheet"

.)

2.

Ask if the customer requests I/M examination.

Malfunction information, obtained>>GO TO 2.
No malfunction information, but a request for I/M examination>>GO TO 13.

2.

CHECK DTC

1.

Check DTC.

2.

Perform the following procedure if DTC is displayed.

Record DTC and freeze frame data. (Print them out with CONSULT or GST.)

-

Erase only DTC of “ENGINE”.
With CONSULT: “How to Erase DTC and 1st Trip DTC” in 

EC-71, "CONSULT Function"

.

Without CONSULT: “How to Erase Self-diagnostic Results” in 

EC-68, "On Board Diagnosis Function"

.

-

Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Matrix Chart is useful. Refer to 

EC-547, "Symptom Table"

.)

3.

Check related service bulletins for information.

Are any symptoms described and any DTCs 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 MIL ON).

EC-554, "Description"

 and 

EC-

97, "Fail Safe"

.

Diagnosis Work Sheet is useful to verify the incident.
