API Implementation of the OBDonUDS Standard (SAE J1979‑2)
The standard OBDonUDS (SAE J1979-2) describes the communication between on-board diagnostic systems of vehicles and corresponding test equipment. OBDonUDS was designed as the successor to the OBD-2 standard which has reached its limits, as on-board diagnostics have become increasingly complex.
Based on the established UDS standard (ISO 14229-1), OBDonUDS creates structures and functionality for improved vehicle diagnostics and monitoring. For example, more DTC error codes are possible, and more detailed data is captured for each error.
The free PCAN-OBDonUDS API provides the services of the OBDonUDS standard with its functions. Diagnostic data is exchanged via CAN by utilizing the underlying PCAN-UDS API.
