Abstract
The 1984 Continental Mark VII electronic instrument cluster is reviewed with emphasis on the software algorithm used to store the odometer value in the non-volatile memory. The algorithm, through the use of multiple storage locations, parity checks, and relationship checks, increases the integrity and reliability of the non-volatile memory and minimizes the loss of distance associated with partial memory failures. The criteria and rationale used to develop the algorithm is discussed along with a brief description of the operation of the algorithm.
