ABSTRACT:
A tester for an electronic engine control system is provided with an output circuit through which test signals are delivered to the electronic engine control system. The electronic engine control system responds to the test signals to deliver response signals to the tester. The response signals outputted are sent through an input circuit to a judgement circuit where the response signals are operated upon, compared and judged to check to see whether operation of the engine control system is proper or not. The result of the checking is displayed by a display circuit.
