UDS (Unified Diagnostic Service) is based on the standards KWP2000 for K-Line and CAN. It was developed with the goal of standardizing different implementations of the predecessor standards and new requirements stemming from further developments in technology and new standards to form one generally valid diagnostic protocol. UDS describes the layer 7 protocol (diagnostic services) but is based on an extended version of the diagnostic protocol of KWP2000 on CAN (ISO 15765-2).
