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 in the problem analysis:
What
| Vehicle model, system name
|
When
| Date, time, occurrence frequency
|
Where
| Road conditions
|
Under what conditions?
| Running conditions, driving conditions, weather conditions
|
How did it happen?
| Problem symptoms
