Abstract
A controller for a hydraulic control system includes a microprocessor having a diagnostic routine. The diagnostic routine is operable to exercise an arithmetic logic unit within the microprocessor to verify that the arithmetic logic unit is functioning properly. Upon detection of a malfunction of the arithmetic logic unit, the diagnostic routine disables the hydraulic control system and generates a warning signal.
