2.1 What is OBD-II?
OBD-II stands for On-Board Diagnostics, II generation. It is a set of documents issued by SAE and
ISO, which describe the interchange of digital information between on-board emission-related
Electronic Control Units (ECUs) of road vehicles and an OBD-II scan tool. OBD-II also commonly
refers to the physical on-board diagnostic system of a vehicle, which consists of an ECU (or
multiple ECUs), Malfunction Indicator Light(MIL), Diagnostic Link Connector (DLC), and the wiring
that connect the different elements.
