Abstract
A failure-monitor system for a digital control system includes one or more fault indicators which are adapted to turn on in response to failure of corresponding elements of the digital control system. The failure-monitor system is associated with a preselected switch operated when the vehicle is moving, such as an ignition switch, and responsive to turning on of the switch to initialize the failure-monitor system after maintenance has been completed. The failure-monitor system also includes an alarm indicator which is turned on when malfunction of one of the segments or elements of the digital control system is detected.
