Abstract

A system and method for querying an on board diagnostic system of a vehicle includes a processor, a port in communication with the processor and an input device in communication with the processor. The port is configured to communicate with the on board diagnostic system of a vehicle. The input device is configured to receive a vehicle identification number of the vehicle. The processor is configured to determine protocol utilized by the vehicle based on the vehicle identification number of the vehicle and the data in a database which contains data to identify the protocol the vehicle utilizes. After a determination of the protocol utilized by the vehicle is performed, the processor is further configured to communicate with the vehicle using the protocol previously identified.

Claims

1. A device for querying an on board diagnostic system of a vehicle, the device comprising:

a processor;

a port in communication with the processor, the port being configured to communicate with the on board diagnostic system of a vehicle;

an input device in communication with the processor, the input device configured to receive a vehicle identification number of the vehicle;

a database in communication with the processor, the database comprising data to identify the protocol the vehicle utilizes;

wherein the processor is configured to determine protocol utilized by the vehicle based on the vehicle identification number of the vehicle and the data in the database; and

wherein, after a determination of the protocol utilized by the vehicle is performed, the processor is further configured to communicate with the vehicle using the protocol previously identified.

2. The device of claim 1, wherein the input device is a keypad or touchscreen, wherein the keypad or touchscreen is configured to receive an input from an operator.

3. The device of claim 1, wherein the input device is scanner configured to read the vehicle identification number from at least one location of the vehicle.

4. The device of claim 1, wherein the processor is configured to determine a model year of the vehicle based on the vehicle identification number of the vehicle and the data in the database.

5. The device of claim 4, wherein the processor is configured to determine the protocol utilized by the vehicle based on the model year of the vehicle.

6. The device of claim 1, wherein the processor is configured to determine a make and model of the vehicle based on the vehicle identification number of the vehicle and the data in the database.

7. The device of claim 6, wherein the processor is configured to determine the protocol utilized by the vehicle based on the make and model of the vehicle.

8. The device of claim 1, wherein the processor is configured to determine data items that the on board diagnostic system of the vehicle contains and only request information from the vehicle of the determined data items.

9. A method for querying an on board diagnostic system of a vehicle, the method comprising the steps of:

receiving a vehicle identification number of the vehicle from an input device;

determining a protocol utilized by the vehicle based on the vehicle identification number of the vehicle and the data in a database, the database comprising data to identify the protocol the vehicle utilizes;

after the determination of the protocol utilized by the vehicle is performed, communicating with the vehicle using the protocol previously identified.

10. The method of claim 9, wherein the input device is a keypad or touchscreen, wherein the keypad or touchscreen is configured to receive an input from an operator.

11. The method of claim 9, wherein the input device is scanner configured to read the vehicle identification number from at least one location of the vehicle.

12. The method of claim 9, further comprising the step of determining a model year of the vehicle based on the vehicle identification number of the vehicle and the data in the database.

13. The method of claim 12, further comprising the step of determining the protocol utilized by the vehicle based on the model year of the vehicle.

14. The method of claim 9, further comprising the step of determining a make and model of the vehicle based on the vehicle identification number of the vehicle and the data in the database.

15. The method of claim 14, further comprising the step of determining the protocol utilized by the vehicle based on the make and model of the vehicle.

16. The method of claim 9, further comprising the steps of determining data items that the on board diagnostic system of the vehicle contains and only requesting information from the vehicle of the determined data items.
