Abstract
A method of diagnosing a fault in an in-vehicle communication system. The in-vehicle communication system includes a transmitting node, at least one receiving node, and a network communication bus coupling the transmitting node to the at least one receiving node. A message is transmitted from the transmitting node to the at least one receiving node over the communication bus. A fault detection technique is applied within the transmitting node for detecting a fault within the transmitting node. A fault detection technique is applied to the at least one receiving node for detecting a fault within the at least one receiving node. A fault detection technique is applied within the network communication bus for detecting a fault within the communication bus. An analyzer collectively analyzes results from each respective detection technique for isolating a fault within the in-vehicle communication system.
