HINT: 

• 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 malfunctions 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 and time, frequency, whether the problem occurred recently or has been occurring for a long time
  Where	Whether the problem occurs at specified location
  Under what conditions?	Whether the doors were locked or unlocked, whether the ignition switch was ON, whether the hybrid control system was starting
  How did it happen?	Ask the customer for details about the vehicle operating conditions, environment and malfunction.
