Answer

OBD stands for on-board diagnostics, an automotive term that refers to a vehicle’s diagnostic and reporting capabilities. The OBD is a valuable tool for repair technicians, vehicle owners, and fleet managers, as it is used to monitor the health and performance of the vehicle engine and emissions system. Vehicle manufacturers first started to build this computer system into vehicles in 1996. The GO device connects to the OBDII port out of the box, which is a standardized connector in most vehicles today.

The amount of diagnostic information available through the OBD, which is given in specific diagnostic trouble codes (DTCs), varies for each vehicle make and model. This blog provides more information about diagnostic ports.
