A vehicles’ computerized diagnostic and reporting is known as On-board diagnostics (OBD). Today, all consumer vehicles are required by law to have an OBD interface. The OBD-II specification is what is in use in most automobiles today. OBD-II can be accessed via a specific 16-pin connector which is also standardized under SAE J1962.
Heavy-duty vehicles utilize J-BUS, sometimes referred to as the Modbus protocol, for vehicle diagnostics. J-BUS devices are typically accessed with one of two connectors – a 6-pin J1708 or a 9-pin J1939.
