Study of KWP2000, CAN, and UDS Communication Protocols for Automotive Diagnostic

Abstract

Diagnostic systems must be used to monitor and control parameters as the number of embedded electronic components in automobiles increases. All sectors of the economy, from development to production to after-sales, depend on diagnostic systems to do their tasks. It takes a lot of work to create one for an automobile component or system. However, ISO and SAE have identified a variety of diagnostic system types depending on the types of systems and specific diagnostics from the manufacturers. In certain circumstances, the length can even more than double. The three communication standards that the diagnostic tools in a car network utilize to communicate with one another are KWP2000, CAN, and UDS. This article covers the necessary tools and applications for each diagnostic and service communication protocol in addition to introducing them.
