Patent ID: 7136729

Claim:
A method for performing a diagnostic check of an integrated vehicle stability system, said method comprising: providing at least one primary component and at least one secondary component for sensing an operation of at least one vehicle characteristic; determining whether an output of the at least one primary component and an output of the at least one secondary component are valid; comparing the output of the at least one primary component and the output of the at least one secondary component to determine whether a difference between the outputs is below a predetermined threshold; determining whether a bias of the at least one primary component and a bias of the at least one secondary component is below a predetermined limit; and putting the vehicle stability system in a fail-safe mode if the at least one primary component or the at least one secondary component is not outputting a valid signal, if the bias of the at least one primary component and the at least one secondary component is above the predetermined limit, or the difference between the outputs of the at least one primary component and the at least one secondary component is greater than the predetermined threshold.
