Abstract

A method to monitor integrity of a signal in a distributed control system for a powertrain system includes communications link transmitting signals between control modules. Integrity of each of the control modules is monitored. The signal is generated and verified in an originating control module and transmitted to a receiving control module whereat it is subsequently verified.
