PCAN-PassThru API

Pass-Thru API and Connection of Pass-Thru Software to PEAK CAN Interfaces

For the programming of control units (ECU), there are countless applications from various manufacturers which are used in the development and diagnosis of vehicle electronics. The interface for the communication between these applications and the control units is defined by the international standard SAE J2534 (Pass-Thru). Thus, the hardware for the connection to the control unit can be selected regardless of its manufacturer.

PCAN-PassThru allows the use of SAE J2534-based applications with CAN interfaces from PEAK-System.

The functions defined by the standard are provided by Windows® DLLs. These can also be used to develop own Pass-Thru applications.

The communication via CAN and OBD-2 (ISO 15765-4) is based on the programming interfaces PCAN-Basic and PCAN-ISO-TP. PCAN-PassThru is supplied with each PC CAN interface from PEAK-System.

CAN FD

Due to the implementation of the SAE J2534 extension GMW17753 from General Motors, PCAN-PassThru beginning with version 2 supports the new CAN FD standard (CAN with Flexible Data rate) which is primarily characterized by a higher bandwidth for data transfer.

  • Implementations of the international standards SAE J2534 (Pass-Thru) version 04.04 and 05.00
  • Extension implementations in version 04.04:
    • SAE J2535-2:2019 to support CAN FD
    • GMW17753 from General Motors to support messages extension
  • Extension implementations in version 05.00:
    • SAE J2535-2:2019 with adaptations to match version 05.00 to support CAN FD
    • GMW17753 from General Motors to support messages extension
  • Use of SAE J2534 applications with PC CAN interfaces from PEAK-System
  • Windows® DLLs for the development of of your own SAE J2534 applications for the platforms Windows® 11 (x64/ARM64), 10 (x86/x64)
  • Thread-safe API
  • Physical communication via CAN and OBD-2 (ISO 15765-4) 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 via the CAN bus up to 4095 bytes or 32768 bytes with the GMW17753 extension
