Abstract
System and method for determining whether a first operation is responsive to a controller. A second operation, whose successful functioning depends on the successful functioning of the first operation and which produces a sensible result, is initiated while the first operation is inhibited by the controller. Sensing that the second operation is producing a result indicates that the first operation is not responsive to the controller. A further test is provided to determine whether the second operation is functioning properly.
