.TSE File Extension
What is a TSE file?
A TSE file is a diagnostic service event file created by Toyota Techstream diagnostic software. It contains a log of actions performed during a diagnostic service session. For example, TSE files might contain a record of trouble codes retrieved from a vehicle.
Toyota Techstream is a Windows application that service technicians can use to connect to, retrieve information from, and program Toyota, Scion, and Lexus vehicles. It is typically installed on laptops or tablets. While performing a diagnostic service session, technicians can save a log of the actions they performed in Techstream to a TSE file. They can also export a log of the actions as a .CSV file, for use in other programs.
How to open a TSE file
You can open a TSE file in Toyota Techstream (Windows) to view the service event data it contains.
