UDS – ISO 14229<\/h2>\n\n

The advent of new bus systems necessitated a protocol independent of them. Based on KWP 2000<\/strong>, the new UDS (Unified Diagnostic Services<\/strong>) protocol was developed and defined in ISO standard 14229<\/strong>. Among other changes, KWP 2000 services were regrouped and consolidated using a new parameter: the sub-function level<\/strong>. Furthermore, new functionalities were introduced, such as a security layer<\/strong> for encrypted services, event-driven service execution<\/strong>, and the suppression of positive responses<\/strong> from control units. <\/p>\n\n

Since CAN is limited to 8 bytes of payload data, the implementation of UDS over CAN was additionally specified in ISO 15765-3<\/strong>.<\/p>\n\n
