ABSTRACT:
A method is provided for monitoring communications in a machine including electronic control module (ECM) components connected via datalinks. A message is received on a datalink. The source address of the received message is determined. The received message is added to an address list based on the source address, and the address list is evaluated to determine the status of a datalink associated with each ECM component.
