DIAGNOSIS AND REPAIR WORK FLOW
Work Flow
DETAILED FLOW
1.INTERVIEW FROM THE CUSTOMER
Clarify customer complaints before inspection. First of all, perform an interview utilizing DAS-202, "Diagnostic Work Sheet" and reproduce the symptom 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”.

2.CHECK SYMPTOM
Reproduce the symptom that is indicated by the customer, based on the information from the customer obtained by the interview. Also check that the symptom is not caused by fail-safe mode. Refer to DAS-191, "Fail-Safe (Chassis Control Module)".
CAUTION: When the symptom is caused by normal operation, fully inspect each portion and obtain the understanding of customer that the symptom is not caused by a malfunction. >> GO TO 3.
3.PERFORM SELF-DIAGNOSIS
With CONSULT
Is DTC detected? YES >> Record or print self-diagnosis results and freeze frame data (FFD). GO TO 4.
