• When 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	Road conditions
  Under what conditions?	Driving conditions, weather conditions
  How did it happen?	Problem symptoms

1. Check that condensation is not likely to occur in the cabin and that the temperature is not high or extremely low in the cabin.

   OK

   Condensation is not likely being produced and the temperature is not high or extremely low.

   HINT: 

   • A humid cabin and a rapid change in temperature may lead to condensation. Condensation in the cabin may cause a short circuit.
   • The audio and visual system may not operate normally when the temperature is -20°C (-4°F) or lower, or 65°C (149°F) or higher.
