Arduino-Based Automotive Diagnostic Tester.

The work presented introduces a system that encompasses general notions about the dashboard computer and Arduino platform, used to create an automotive diagnostic tool through the OBDII port. This involves establishing a connection between the Arduino platform, a Bluetooth module, and a Bluetooth adapter that communicates with the Engine Control Unit (ECU), transmitting information displayed on an LCD screen. To highlight the system's performance, a comparison of results was conducted with an authorized automotive tester from an auto service, using two different vehicle models. [ABSTRACT FROM AUTHOR]
