programming of the vehicle’s ECU’s. The J2534 Configuration Application is installed onto your PC at the same time as the MDI Manager software allowing you to control how your TIS 2 Web application will connect to an MDI.
In addition, this application provides API Monitoring controls to aid in investigating problems encountered while using any J2534 devices (including the MDI).
To launch the J2534 Configuration Application from SPS, press the “configuration” button on the Diagnostic settings screen.
