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 for problem analysis:

     What	Vehicle model, system name
     When	Date, time, occurrence frequency
     Where	Whether the problem occurs at a specific location
     Under what conditions?	Whether the doors were locked or unlocked, whether the ignition switch was on, whether the engine was running
     How did it happen?	Problem symptoms
