The protocol or system EOBD or Diagnostic on European Board, are a band of standards deployed in Europe since the year 2000. This European regulation has forced the producers of vehicles to place diagnostic machines to their new vehicles with standardized interfaces and connectors. Additionally, these manufacturers are also required to disclose or publish important details of their diagnostic systems.
Through this system EOBD identifies all types of error codes that presents the vehicle, which is recorded on the car’s computer. The EOBD system in conjunction with the computer performs an analysis of the following systems: ignition, injection, abs, among others; in this way the time that can be lost is minimized by looking for problems and breakdowns. Additionally, it controls the emissions of exhaust gases that pollute the environment.
The EOBD system works through sensors that are closely related to the vehicle’s exchange or computer; when a fault occurs, this system turns on a warning light on the dashboard for the driver to perform the respective analysis or diagnosis.
This EOBD protocol controls important functions in both gasoline-powered and diesel-fueled vehicles.
The EOBD regulations began to be applied in Europe, to all the new cars of the different manufacturing companies, with gasoline engines since 2000, with diesel engines since 2003 and since 2005 it is also mandatory in buses and heavy vehicles with more than 3.5 tons.
