Abstract

An apparatus and method is disclosed for preventing the performance of an automatic sequence of operations of a work vehicle. The apparatus is a system that includes a databus, a plurality of input devices, a primary control unit coupled to the plurality of input devices and to the databus, a plurality of output devices and a plurality of secondary control units coupled to the databus, each of the secondary control units also being coupled to at least one of the output devices. The primary control unit directs the performance of the automatic sequence of operations by generating commands to be provided onto the databus. Each of the secondary control units directs an output function by the at least one output device coupled thereto in response to the commands on the databus. At least one of the secondary control units provides a status signal onto the databus indicative of a status of the at least one of the secondary control units or the respective output device, wherein the primary control unit prevents the performance of the automatic sequence of operations if the status signal is indicative of a system malfunction.
