Windows application ddt4all allows you to perform self-diagnosis and search for minor ECU faults. Many Dacia and Renault cars are supported. It is possible to adjust the configuration and reset incorrect settings. This allows you to solve many failures and restore performance without recourse to specialized organizations. For correct operation it is necessary to pre-install PyQt and Python components by downloading the latest versions from the official resource.

Connection

Before opening the program, you need to connect a special ELM327 connector to the PC, which will provide communication with the electronics of the car (can be purchased in specialized stores).
