PCAN-OBD-2 API

API Implementation of the OBD-2 Standard (ISO 15765-4)

For on-board diagnostics, the OBD-2 standard defines the exchange of specific vehicle parameters. The client makes a request on the connected control units (ECUs) in the vehicle to which one or several ECUs are answering. As part of OBD-2, the ISO 15765-4 standard describes the CAN bus as a transmission option.

The PCAN-OBD-2 API implements the functionality of the standard on the basis of 15 functions. They are categorized in Tester Allocation, Configuration, Information, Services, and Communication.

According to ISO 15765-4, OBD-2 is based on UDS. Analog to this, PCAN-OBD-2 uses the PCAN-UDS programming interface for the exchange of diagnostic data.

  • Implementation of the OBD-2 protocol (ISO 15765-4) 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
