ABSTRACT:
In a diagnosis apparatus for an electronic control system adapted to vehicles and including a speed sensor for producing speed pulses responsive to the actual vehicle speed, a switch produces a diagnosis signal when actuated upon request for self-diagnosis in operation of the control system. A computer is responsive to the diagnosis signal to discriminate change of the level of each speed pulse during movement of the vehicle and to produce a first signal in dependence upon discrimination of change of the level of each speed pulse and a second signal in dependence upon discrimination of unchangeable state of the level of each speed pulse, and an indicator indicates an error in operation of the speed sensor in response to the second signal and normal operation of the speed sensor in response to the first signal.
