There is a lot of information about the J2534 (Pass-Thru) standard, so there is no need to describe it. Briefly, J2534 describes a Windows API for communication between ECU and PC. Currently, there are many diagnostic adapters from different manufacturers that support J2534 API.
J2534-1 only describes standard features and protocols such as ISO9141, KWP2000,
J2534-2 describes optional Pass-Thru features such as pin selection, use of Single Wire CAN (SW CAN), and additional protocols. There are few adapters that fully comply with the J2534-2 standard, most of them only partially conform to J2534-2.
Below is a description of the hardware capabilities of some of the J2534 adapters tested with DAP4CS.
DAP4CS has also been tested with Mini-VCI clone, and bugs have been found in the accompanying J2534 library, which in some cases can lead to a loss of communication with the Control Units. It is possible that the accompanying DLLs of other adapters may also contain bugs, therefore stable operation with other J2534 adapters is not guaranteed as they have not been tested.
If your J2534 adapter supports USB and wireless, please use a USB connection as using wireless causes a significant increase in latency between the adapter and the PC.
✅ J2534 support is an additional option of DAP4CS license key. The cost of this option is 50 USDT.
