First Claim
Patent Images
1. A system for communicating vehicle diagnostic data, comprising:
- a first vehicle component that detects a vehicle diagnostic condition; and
a second vehicle component that wirelessly communicates with a call center and is in communication with the first vehicle component, wherein, in response to the first vehicle component detecting the vehicle diagnostic condition;
i) the second vehicle component makes a first wireless call to the call center, wherein the first wireless call includes information representative of the vehicle diagnostic condition;
ii) the call center wirelessly sends a temporary number to the second vehicle component while the first wireless call is still in progress;
iii) the call center removes the temporary number after the temporary number has expired; and
iv) the temporary number is a mobile dialing number/mobile identification number (MDN/MIN) that is paired with an electronic serial number (ESN) of the second vehicle component.

Abstract
A system and method for communicating vehicle diagnostic data via an inactive telematics unit. A serious diagnostic condition detected in the vehicle is used to trigger a call from the telematics unit to a call center using a cleared number. During the call, diagnostic data can be transmitted to the call center and a temporary number can be provided by the call center to the telematics unit to permit temporary communication. Additional diagnostics can be run and reported using this temporary number.

8. A method for communicating vehicle diagnostic data, comprising the steps of:
-
(a) detecting a vehicle diagnostic condition; (b) evaluating the vehicle diagnostic condition at the vehicle to determine if it is a serious diagnostic condition; (c) if the vehicle diagnostic condition is determined to be a serious diagnostic condition, then retrieving a cleared number that expires based on time or mileage and that is stored in memory at the vehicle and enables a telematics unit to make a wireless vehicle-originated call even though the telematics unit is inactive; and (d) making the wireless vehicle-originated call using the cleared number from the vehicle to the call center, wherein the wireless vehicle-originated call includes information representative of the serious diagnostic condition. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. Method for communicating vehicle diagnostic data, comprising the steps of:
-
(a) detecting a vehicle diagnostic condition with a vehicle system module (VSM) and sending a diagnostic trouble code (DTC) from the VSM over a vehicle communications bus, wherein the DTC is representative of the vehicle diagnostic condition; (b) receiving the diagnostic trouble code (DTC) at a telematics unit and comparing the DTC to a list of DTCs saved in memory in order to determine if the DTC is a serious DTC; (c) if the diagnostic trouble code (DTC) is a serious DTC, then retrieving a cleared number that is stored in memory and enables the telematics unit to make a wireless vehicle-originated call even though the telematics unit is inactive; (d) using the cleared number to make a wireless vehicle-originated call from the telematics unit to a call center, wherein the vehicle-originated call includes information that is representative of the diagnostic trouble code (DTC); (e) activating the telematics unit with a temporary number that enables the telematics unit to receive wireless vehicle-terminated calls, wherein the activation at least partially occurs while the wireless vehicle-originated call is still in progress; and (f) deactivating the telematics unit after the temporary number expires.
