CUSTOMER PROBLEM ANALYSIS
Tech Tips
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? | Whether the doors were locked or unlocked, whether the ignition switch was ON, whether the engine has started |
