Although the specification is hardware layer independent, it is often used on the CAN (Controller Area Network) hardware layer.

ISO14229 FEATURES IN VEHICLE SPY
Vehicle Spy's ability to transmit and receive ISO15765-2 messages automatically with no scripting or programming enables you to define all ISO14229 Messages to transmit requests and receive responses for any diagnostics. In addition, you filter responses based not only on the CAN Arbitration ID, but also on the data bytes in the messages. This enables you to define multiple responses for multiple diagnostic commands.
