Abstract
A method and system for utilizing a telematics unit on a telematics-equipped vehicle as a register for ECU Critical Information (ECI) associated with the ECUs in the vehicle, which may include their serial numbers, configurations, software images, and other data includes the telematics unit querying ECUs within the telematics-equipped vehicle such as, for example, when the vehicle is started. The ECUs may then provide the telematics unit with the ECI associated with each ECU. The ECI may be encrypted, and the telematics unit may provide each module that it queries with a nonce used in the encryption process. The telematics unit may then decrypt the ECI received from each of the ECUs and compare the received ECI to previously stored ECI. If the received ECI is different from the previously stored ECI, the telematics unit may send the new ECI to a TSP call center. Both the telematics unit and the call center may replace the previously stored ECI with the new ECI and may maintain records of previously stored ECI and updates to the ECI.
