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 adapters from PEAK-System.
The functions defined by the standard are provided by Windows® DLLs for 32 and 64-bit systems. 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.
