System and method for sending and receiving messages between an electronic control unit of a vehicle and an external device
First Claim
1. A device for sending and receiving messages between an electronic control unit of a vehicle and an external device, the device comprising:
- a processor;
a memory in communication with the processor;
a first port in communication with the processor, wherein the first port is configured to communicate with the electronic control unit of the vehicle;
a second port in communication with the processor, wherein the second port is configured to communicate with the external device, wherein the external device is a vehicle emissions testing device that is configured to determine that the vehicle has passed an emissions test; and
wherein the processor is configured to;
receive a request message from the vehicle emissions testing 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,determine a first information subset in the requested information that should be transmitted to the vehicle emissions testing device and a second information subset in the requested information that should not be transmitted to the vehicle emissions testing device, wherein the information found in both the first information subset and the second information subset of the requested information was requested in the request messagetransmit the first information subset to the vehicle emissions testing device, wherein the first information subset provided to the vehicle emissions testing device results in a pass indication by the vehicle emissions testing device, indicating that the vehicle has passed the emissions test based on the first information subset provided to the vehicle emissions testing device, andnot transmit the second information subset, wherein the second information subset contains a portion of the requested information that if provided to the vehicle emissions testing device would result in a fail indication by the vehicle emissions testing device.

Abstract
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.
