Abstract
A method of performing vehicle diagnostics including receiving diagnostic information from at least one electronic module of a vehicle at a portable communication device from a telematics unit via a short-range wireless connection, storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database, performing a diagnostic analysis based on the recent-history vehicle database and sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.
Claims21
A method of performing vehicle diagnostics, comprising:
- sending diagnostic information from an electronic module of a vehicle to a vehicle communication device located in the vehicle, wherein the sending step further comprises sending the diagnostic information over a vehicle communication network that interconnects the vehicle communication device with a plurality of other electronic modules;
- sending the diagnostic information from the vehicle communication device to a portable communication device, wherein a short-range wireless chip in the vehicle communication device communicates the information from the vehicle communication device to the portable communication device via a short-range wireless connection;
- storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database, wherein the storing step further comprises storing the received diagnostic information alone with previously-received diagnostic information such that the recent-history vehicle database includes both the received diagnostic information and the previously-received diagnostic information;
- performing a diagnostic analysis based on the recent-history vehicle database;
- and
- sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.

A system for performing vehicle diagnostics, the system comprising:
- means for sending diagnostic information from an electronic module of a vehicle to a vehicle communication device located in the vehicle, wherein the electronic module receives the diagnostic information over a vehicle communication network that interconnects the vehicle communication device with a plurality of other electronic modules;
- means for sending the diagnostic information from the vehicle communication device to a portable communication device, wherein a short-range wireless chip in the vehicle communication device communicates the information from the vehicle communication device to the portable communication device via a short-range wireless connection;
- means for storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database;
- means for performing a diagnostic analysis based on the recent-history vehicle database;
- and
- means for sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.
3 more elements
A computer readable medium storing a computer program comprising:
- computer readable code for diagnostic information from an electronic module of a vehicle to a vehicle communication device located in the vehicle, wherein the electronic module receives the diagnostic information over a vehicle communication network that interconnects the vehicle communication device with a plurality of other electronic modules;
- computer readable code for sending the diagnostic information from the vehicle communication device to a portable communication device, wherein a short-range wireless chip in the vehicle communication device communicates the information from the vehicle communication device to the portable communication device via a short-range wireless connection;
- range wireless connection;
- computer readable code for storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database, wherein the computer readable code for storing the received diagnostic information includes computer readable code for storing the received diagnostic information alone with previously-received diagnostic information such that the recent-history vehicle database includes both the received diagnostic information and the previously-received diagnostic information;
- computer readable code for performing a diagnostic analysis based on the recent-history vehicle database;
- and
- computer readable code for sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.
