Cellphone based vehicle diagnostic system
First Claim
1. A wireless vehicular diagnostic communication system for wireless communication of vehicle diagnostic information from a vehicle 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 also having a local connectivity circuit for communicating the vehicle diagnostic information between the code reader and a wireless local connectivity network; and
a cellphone in wireless communication with the wireless local connectivity network for communicating the vehicle diagnostic information wirelessly between the code reader and the cellular telephone network via a first wireless communication pathway from the code reader to the cellphone in combination with a second wireless communication pathway from the cellphone to the cellular telephone network;
wherein said cellphone comprises a first indicator configured to provide a data-ready signal to indicate receipt of diagnostic trouble codes from said local connectivity circuit of said hand portable code reader, and a second indicator configured to indicate the presence of one or more pre-determined trouble codes, or other diagnostic information, indicative of a more immediate need for attention.
