Abstract

An equipment service vehicle comprises a network communication link, a plurality of vehicle subsystems, a test control module, and an operator interface. The test control module is mounted on board the vehicle and is coupled to the plurality of vehicle subsystems by way of the network communication link. The test control module is programmed to acquire at least some of the information pertaining to the health and operation of a mechanical system. The operator interface is mounted on board the vehicle and is coupled to the test control module. The operator interface comprises a display that displays a menu of test options to an operator and an input device that receives an operator input indicative of a menu selection made by the operator. At least some of the information pertaining to the health and operation is displayed to the operator.
