What Is OBD?

On-board diagnostics (OBD) is an automotive term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers.

What Is A Car Diagnostic?

When a person buys a car, he usually expects it to run well for a long time. To this end, car manufacturers have developed sophisticated computer systems that keep the car in check and help to keep it running smoothly. Those systems will also light up the check engine light when there is something wrong with the car.

What OBD Protocol Does My Car Use?

There is a chance that your car may not use any OBD protocol. Many vehicles are able to communicate with some form of scan tool, but may not use an OBDII protocol. If your car is older, or from a country that does not require OBD, then your car may not respond to OBD requests for data.
