DETAILED FLOW 

1. COLLECT THE INFORMATION FROM THE CUSTOMER 

   It is also important to clarify customer complaints before inspection. First of all, reproduce symptoms and understand them fully. Ask customer about his/her complaints carefully. In some cases, it is necessary to check symptoms by driving vehicle with customer.

   CAUTION:

   Customers are not professional. It is dangerous to make an easy guess like "maybe the customer means that..," or "maybe the customer mentions this symptom".
