Abstract:
The increasing application of embedded electronic components in vehicles brings the need to use diagnostic systems for track and control of parameters.Development, manufacturing and after-sales are all fields that use diagnostic systems' help to execute their tasks.Applying communication protocols such as KWP2000, SAEJ1939/73 and UDS makes diagnostic device and automotive network communicate to each other according to standards.This work aims to present an overview about a few communication protocols for diagnostic and services, by showing their specific tools and applications.
