    See step  2

  2. CUSTOMER PROBLEM ANALYSIS 
    1. Confirm whether the malfunction occurred during AC charging or DC charging.

      HINT: 

      After confirm the result of the interview with the customer, by referring Vehicle Control History (RoB) item "AC Charging History (X10F0)" or "DC Charging History (X10F1)"the detailed status of the plug-in charging event in which the malfunction occurred can be known.

      Result

      Result Proceed to
      Malfunction has occurred during performing AC charging. A
      Malfunction has occurred during performing DC charging. B
