2. CUSTOMER PROBLEM ANALYSIS

   Tip:

   • In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.

   • Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.

   • The following 5 items are important points in the problem analysis:

   What	Vehicle model, system name
   When	Date, time, occurrence frequency
   Where	Road conditions
   Under what conditions?	Running conditions, driving conditions, weather conditions
   How did it happen?	Problem symptoms
