Remote diagnostic system for detecting tampering of vehicle calibrations
First Claim

1. A tampering diagnostic system for a vehicle, comprising:
- a vehicle control system that encodes calibration data of the vehicle and that generates cyclical redundancy check (CRC) data for the encoded calibration data;
a transmitter that selectively wirelessly transmits the encoded calibration data and the CRC data; and
a manufacturer information system that is remote from the vehicle, that wirelessly receives the encoded calibration data and the CRC data, that selectively generates a tampering flag associated with the vehicle based on a comparison of the encoded calibration data and predetermined calibration data for the vehicle, and that selectively disables the comparison based on the CRC data.

Abstract
A tampering diagnostic system for a vehicle comprises a control system that stores calibration data. A transmitter selectively wirelessly transmits the calibration data. A service assistance system that is remote from the vehicle receives the calibration data wirelessly from the transmitter. A manufacturer information system receives the calibration data from the service assistance system, compares the calibration data to factory calibration data, and selectively generates a tampering flag based on the calibration data.

8. A tampering diagnostic method for a vehicle, comprising:
-
encoding calibration data of the vehicle; generating cyclical redundancy check (CRC) data for the encoded calibration data; selectively wirelessly transmitting the encoded calibration data and the CRC data; wirelessly receiving the encoded calibration data and the verification data at a location that is remote to the vehicle; selectively generating a tampering flag associated with the vehicle at the location based on a comparison of the encoded calibration data and predetermined calibration data for the vehicle; and selectively disabling the comparison based on the CRC data. - View Dependent Claims (9, 10, 11, 12, 13, 14)
