Tag: UDS

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).

Information poster for free | DoIP – standardized vehicle diagnostics over Ethernet With Diagnostics over IP, diagnostic services introduced over UDS are used over TCP/IP and Ethernet. This enables much higher data rates than with CAN, representing great potential for savings both in terms of time and expenses in the case of complex diagnostic tasks and flash applications.
