CUSTOMER PROBLEM ANALYSIS |
HINT:
- 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
Where
Road conditions
Under what conditions?
Driving conditions, weather conditions
How did it happen?

READ OUT AND SAVE OPERATION HISTORY |
NOTICE:
- If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before operation history has been read out and saved, the operation history information could be lost.
- The function "Read operation history" uses the current system time setting inside the Techstream and the time counter inside the controlling ECU to calculate the timings shown in the operation history. For this reason, before reading out the operation history, first make sure that the Techstream system clock is accurately set to the current time.
(a) Read out and save operation history using the Techstream.
