PCAN-UDS API

API Implementation of the UDS Standard (ISO 14229-1)

UDS (ISO 14229-1) stands for Unified Diagnostic Services and defines the communication with control units (ECUs). The Windows software tests the controller using various services. The process is done on the client-server principle where the program is in the position of the client (also called tester). UDS uses the ISO-TP standard as transport protocol, thus UDS can transmit data blocks of up to 4 GBytes size. Besides the exchange of maintenance information, for example, the transfer of firmware is possible.

The PCAN-UDS API implements the functionality of the standard on the basis of 8 functions. They are categorized in Tester Allocation, Configuration, Information, Utilities, Services, and Communication.

  • Implementation of the UDS protocol (ISO 14229-1) for the communication with control units
  • Windows® DLLs for the development of applications for the platforms Windows® 11 (x64/ARM64), 10 (x86/x64)
  • Thread-safe API
  • Physical communication via CAN or CAN FD using a CAN interface of the PCAN series
  • Uses the PCAN-Basic programming interface to access the CAN or CAN FD hardware in the computer
  • Uses the PCAN-ISO-TP programming interface (ISO 15765-2:2016) for the transfer of data packages up to 4 GBytes via the CAN bus

System requirements


  • Windows® 11 (x64/ARM64), 10 (x64)
