It was developed on the basis of the PCAN-OBD-2 API, which can be used free of charge. This offers an easy way to develop your own applications that are based on the OBD-2 communication standard. The tool and the API can be used with all PC-CAN interfaces from PEAK-System.

OBD-2 stands for On-Board Diagnostics. It is a standard that specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, the message format, a candidate list of vehicle parameters to be monitored, and information on encoding the data for the parameters. The OBD communication protocol is defined in the specifications SAE J1979 or ISO 15031-5, the specific implementation for the CAN bus in ISO 15765-4. It is a client-server oriented protocol.
