12. The system as recited in claim 1 wherein the cellphone is in communication with a public telephone network.

13. The system as recited in claim 1 wherein the vehicle diagnostic port of the code reader is plug engageable to the vehicle diagnostic port.

14. The system as recited in claim 13 wherein the computer data port connector is plug engageable to a computer data port.

15. The system as recited in claim 14 wherein the code reader computer data port connector includes a USB connector.

16. The system as recited in claim 10 wherein the code reader is configured to receive and display at least a portion of the vehicle diagnostic information, independent of the cellphone.

17. The system as recited in claim 16 wherein the code reader further comprises a computer data port connector, for communicating the vehicle diagnostic information between the code reader and a computer data port.

18. The system as recited in claim 1 wherein the code reader communicates control signals between the vehicle diagnostic port and the local connectivity network.

19. The system as recited in claim 1, wherein the cellphone is configured to autonomously communicate the vehicle diagnostic information to the cellular telephone network upon receipt of the vehicle diagnostic information by the cellphone.

20. A wireless vehicular diagnostic communication system for wireless communication of vehicle diagnostic information from a vehicle to a remote service provider over a cellular telephone network, the system comprising:

a hand transportable code reader having a vehicle diagnostic port connector connectable to a vehicle diagnostic port for receiving the vehicle diagnostic information from the vehicle diagnostic port, the code reader having a display for displaying at least a portion of the vehicle diagnostic information;
