A machine diagnostic system processes data from one or more machines to identify events satisfying predetermined event conditions indicative of faulty operation, and for each identified event generates an event signature using data associated with the event. The event signatures are then analysed to generate data identifying a prediction of the cause of a fault. The generated fault prediction data may be output to a machine operator to take appropriate action. In an embodiment, each possible event signature is mapped to corresponding fault prediction data in a fault prediction database. Preferably, fault correction data indicating an actual cause of the faulty operation and successful remedial action taken for an event is received by the machine diagnostic system and the fault correction data for the event signature corresponding to the event is updated to take account of the received fault correction data. The machine is preferably a vehicle which collects operational data and transmits the collected operational data to a remote machine diagnostic server which completes the diagnostic analysis and communicates with maintenance workshop servers, vehicle operator servers and back-up servers.
