1.GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2.
2.CHECK DTC WITH AUTOMATIC DRIVE POSITIONER SYSTEM
Check “Self Diagnostic Result” with CONSULT-III. Refer to ADP-31, "
DTCIndex"
Is any symptom described and any DTC is displayed?
Symptom is described, DTC is displayed.>>GO TO 3.
Symptom is not described, DTC is displayed.>>GO TO 6.

3.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
>> GO TO 6.
4.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
>> GO TO 5.
5.CHECK NORMAL OPERATING CONDITION
Check normal operating condition. Refer to ADP-134, "
Description".
Is the incident normal operation?
YES >> INSPECTION END
NO >> GO TO 7.
6.PERFORM DTC CONFIRMATION PROCEDURE
Perform the confirmation pr ocedure for the detected DTC.
Is the DTC displayed?
YES >> GO TO 8.
NO >> Check intermittent incident. Refer to GI-40, "
Intermittent Incident".
7.PERFORM COMPONENT FUNCTION CHECK
Perform the component function check for the isolated malfunctioning point.
>> GO TO 8.
8.DETECT MALFUNCTIONING PA RT BY DIAGNOSTIC PROCEDURE
Isolate the malfunctioning point by performing the diagnos is procedure relevant to the symptom during the
component diagnosis.
>> GO TO 9.
9.REPARE OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the malfunctioning part.
>> GO TO 10.
10.FINAL CHECK
Perform the DTC confirmation procedure (if DTC is detected) or component function check (if no DTC is
detected) again, and then check that the malfunction can be repaired securely.
Are all malfunctions corrected?
