DETAILED FLOW
1.
INTERVIEW FROM THE CUSTOMER
Clarify customer complaints before inspection. First of all, perform an interview utilizing
and reproduce symptoms as well as fully understand it. Ask customer about his/her complaints
carefully. Check symptoms by driving vehicle with customer, if necessary.
CAUTION:
Customers are not professional. Never guess easily like “maybe the customer means that...,” or
“maybe the customer mentions this symptom”.
>> GO TO 2.
2.
CHECK SYMPTOM
Reproduce the symptom that is indicated by the customer, based on the information from the customer
obtained by interview. Also check that the symptom is not caused by protection function. Refer to
CAUTION:
When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the symptom is not caused by a malfunction.
>> GO TO 3.
3.
PERFORM SELF-DIAGNOSIS
With CONSULT
Perform self-diagnosis for “ALL MODE AWD/4WD”.
Is any DTC detected?
YES
>> Record or print self-diagnosis results. GO TO 4.
NO
>> GO TO 6.
4.
RECHECK SYMPTOM
With CONSULT
1.
Erase self-diagnostic results for “ALL MODE AWD/4WD”.
2.
Perform DTC confirmation procedures for the error detected system.
NOTE:
If some DTCs are detected at the same time, determine the order for performing the diagnosis based on
31, "DTC Inspection Priority Chart"
Is any DTC detected?
YES
>> GO TO 5.
NO
>> Check harness and connectors based on the information obtained by interview. Refer to
.
5.
REPAIR OR REPLACE ERROR-DETECTED PARTS
• Repair or replace error-detected parts.
• Reconnect part or connector after repairing or replacing.
• When DTC is detected, erase self-diagnostic results for “ALL MODE AWD/4WD”.
>> GO TO 7.
6.
IDENTIFY ERROR-DETECTED SYSTEM BY SYMPTOM DIAGNOSIS
Estimate error-detected system based on symptom diagnosis and perform inspection.
Can the error-detected system be identified?

NO
>> INSPECTION END
Diagnostic Work Sheet
INFOID:0000000009751066
Description
• In general, customers have their own criteria for a problem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.
• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
