Abstract:
A controller area network (CAN) on a mobile system has a plurality of CAN elements including a communication bus and nodes. A method for monitoring the CAN includes detecting inactive nodes of the CAN and employing an off-board controller to identify a candidate fault in the CAN based upon the inactive nodes of the CAN and a network topology for the CAN. A fault is isolated in the CAN based upon the candidate fault.
