A Model for the Interpretation of Data from an ECU by Means of OBD Devices

The creation of a model for the interpretation and transformation of data from the computer of automobiles (ECU) will serve on a large scale to the automotive sector. The main objective of this work is to facilitate the understanding of the data provided by the ECU of automobiles, through a model composed of five phases (Connection, loading, interpretation, loading and visualization). The model has usability criteria. Each phase is comprised of the most convenient processes for the context, seeking to reduce complexity and inefficiency. Finally, with the application of the proposed model in mobile applications or desktop software, a person can perform an automotive “Diagnostic” with or without mechanical knowledge, will be able to understand and interpret the information provided and will have certainty about the mechanical state of the revised automobile.
