Abstract
A vehicle having a system for validating a variable signal for input to a processor-performed function. An input module receives the signal. A processor tests first and second storage locations of a memory. After testing, the processor stores the signal in the first and second storage locations to obtain first and second stored values. The processor compares the first and second stored values and tests the first stored value for any corruption associated with receipt of the signal by said input module. The processor inputs the first and second stored values to first and second paths for performing the function to obtain two function results, and compares the results.
