Vehicle diagnostic and programming device and method

A device for sending and receiving messages between an electronic control unit of a vehicle and an external device includes a processor, a memory, a first port, and a second port. The memory, first port, and second port are each in communication with the processor. The first port is configures to communicate with the electronic control unit of a vehicle, while the second port is configured to communicate with the external device. The processor is configured to receive a request message from the external device via the second port, transmit the request message to the electronic control unit of the vehicle; receive requested information from the electronic control unit of the vehicle based on the request message, and determine an information subset in the requested information that should be transmitted to the external device; and transmitting the information subset to the external device.
