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, whether the problem occurred recently or has been occurring for a long time
      Where Whether the problem occurs at a specific location
      Under what conditions? Whether the doors were locked or unlocked, whether the power switch was on (IG), whether the hybrid control system has started
