The J2534 Configuration Application:

The Multiple Diagnostic Interface (MDI) is a J2534 device that connects between your computer and the vehicle’s J1962 DLC connector for pass-thru programming of the vehicle ECU.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.


Engine Compartment:

  • Check Engine Compartment for components which may be loose; kinked or pinched vacuum hoses or electrical connections, and for any other missing or disconnected components.
