Abstract: A method for centralization of process sequence checking includes defining a set of steps in a sequence for a process and defining an order of steps in said set of steps. The method includes determining whether one of said steps started independently of others of said steps and determining whether one of said steps completed independently of others of said steps. The method includes determining whether the sequence started, determining whether the sequence completed, and determining whether a sequence fault occurred.

Abstract: A vehicle diagnostics clearing system that detects a clear diagnostic faults flag and clears diagnostic faults from a control module includes a clear diagnostic faults flag monitoring module and a clear diagnostic faults module. The clear diagnostic faults flag monitoring module periodically monitors the clear diagnostic faults flag in the control module. When the clear diagnostic faults flag monitoring module detects that the clear diagnostic faults flag is set, the clear diagnostic faults module clears the diagnostic faults from the control module for a predetermined period.

Abstract: A memory system for a vehicle includes a first memory that is non-volatile, that is rewritable, and that stores a control program and identification data. A second memory is non-volatile. A control module transfers the identification data to the second memory, erases the first memory, rewrites the control program to the first memory, and transfers the identification data from the second memory to the first memory after erasing the first memory. The identification data may include data such as a software version identifier, a programming date, and/or a part number.
