  2. CUSTOMER PROBLEM ANALYSIS CHECK

    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, 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?
