Abstract

A method of removing a vehicle telematics unit from an invalid state includes sensing that the vehicle telematics unit wirelessly received an invalid state code that deactivates the communication function of the vehicle telematics unit from a base station of a wireless carrier system; determining at the vehicle telematics unit that a reset trigger applicable to invalid state codes has been activated; and commanding the vehicle telematics unit to reset the invalid state code when the reset trigger has been activated thereby permitting the vehicle telematics unit to resume its communication function.

Claims (22)

1. A method of removing a vehicle telematics unit from an invalid state, comprising the steps of:

(a) sensing that the vehicle telematics unit wirelessly received an invalid state code that deactivates the communication function of the vehicle telematics unit from a base station of a wireless carrier system;

(b) determining at the vehicle telematics unit that a reset trigger applicable to invalid state codes has been activated; and

(c) commanding the vehicle telematics unit to reset the invalid state code when the reset trigger has been activated thereby permitting the vehicle telematics unit to resume its communication function.

2. The method of claim 1 , further comprising the step of sensing the receipt of the invalid state code using a processor at the vehicle telematics unit.

3. The method of claim 1 , further comprising the step of determining that a vehicle occupant is initiating a call after carrying out step (a).

4. The method of claim 1 , wherein the reset trigger is initiated by a vehicle ignition, a call initiation, or a collision event.

5. The method of claim 1 , further comprising the step of commanding the vehicle telematics unit to reset the invalid state code in response to detecting a deactivation and activation of a vehicle ignition switch.

6. A method of removing a vehicle telematics unit from an invalid state, comprising the steps of:

(a) sensing that the vehicle telematics unit wirelessly received an invalid state code that deactivates the communication function of the vehicle telematics unit from a base station of a wireless carrier system;

(b) detecting the deactivation and subsequent activation of a vehicle ignition switch; and

(c) commanding the vehicle telematics unit to reset the invalid state code in response to detecting the deactivation and subsequent activation of a vehicle ignition switch.

7. The method of claim 6 , further comprising the step of sensing the receipt of the invalid state code using a processor at the vehicle telematics unit.

8. The method of claim 6 , further comprising the step of detecting the deactivation and subsequent activation of a vehicle ignition switch after carrying out step (a).

9. A method of removing a vehicle telematics unit from an invalid state, comprising the steps of:

(a) sensing that the vehicle telematics unit wirelessly received an invalid state code from a base station of a wireless carrier system that deactivates the communication function of the vehicle telematics unit;

(b) detecting an initiation of a call at the vehicle telematics unit after sensing the receipt of the invalid state code;

(c) determining that the initiation of the call generated a reset trigger applicable to the invalid state code;

(d) resetting the invalid state code in response to the determination that the reset trigger exists; and

(e) completing the initiated call from the vehicle telematics unit.

10. The method of claim 9 , wherein the reset trigger is initiated by a vehicle ignition or a collision event.

11. The method of claim 9 , further comprising the step of sensing the receipt of the invalid state code using a processor at the vehicle telematics unit.
