PCAN-OBDonUDS API

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.

• Implementation of the OBDonUDS protocol (SAE J1979-2, ISO 14229-1, ISO 15765-4:2021) as on-board diagnostics standard
• Windows® DLLs for the development of applications for the platforms Windows® 11 (x64/ARM64), 10 (x86/x64)
• Thread-safe API
• Physical communication via CAN using a CAN interface of the PCAN series
• Uses the PCAN-Basic programming interface to access the CAN hardware in the computer
• Uses the PCAN-ISO-TP programming interface (ISO 15765-2) for the transfer of data packages up to 4095 bytes via the CAN bus
• Uses the PCAN-UDS programming interface (ISO 14229-1) for the communication with control units
