Auto diagnosis is a detection technology and considered as the most efficient way to solve auto problem including mechanical and electronic ones. On-Board Diagnostics, or OBD, refers to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or a repair technician access to state of health information for various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since the introduction in the early 1980s of on-board vehicle computers, which made OBD possible [More]
