Abstract:
A method to monitor integrity of a signal generated and communicated in a distributed control module system for a hybrid powertrain system includes generating and verifying signal within an originating control module. A message is generated based upon the signal. The message is transmitted and received at a receiving control module. The signal is extracted from the message and its integrity is verified.
