In the '90s, there were a series of innovations regarding diesel injection systems. We transitioned from purely mechanical rotary injection pumps to electronically controlled rotary injection pumps (similarly for less common inline pumps). Then came radial piston injection pumps with a complex electronic control system based on CAN, PDE injection systems (pump-injector elements), and towards the end of that decade, common rail systems became wide

The OBD-II port was originally designed for vehicle diagnostics, providing a standardized interface. This port allows the diagnosis of various control systems, including those related to the engine and emissions. The CAN is the communication protocol enabling digital devices, such as the ECU (Engine Control Unit), the instrument cluster, and other components, to exchange data on a "DATA BUS."
