Abstract
An agricultural work machine, an agricultural work machine control system, and method for an agricultural work machine having RFID tags to determine a fault condition of machine components, devices, parts or systems. The RFID tags are located on, at, or near machine components or systems to sense a temperature of those components or systems. A receiver/transmitter interrogates the RFID tags and receives the sensed temperatures, and component identifiers. A controller receives the temperatures from the receiver/transmitter and compares the received temperatures to a threshold to determine whether a fault condition exists. If so, the controller transmits an alert signal to a user interface to indicate that a fault condition exists with an identified component, part, device, or system.
