ABSTRACT:
A combined stepper motor tester and pulse train monitor is disclosed for use with a vehicle engine idle air control system. The motor tester comprises a driver pulse generator for generating a pair of pulse trains for energizing the two coils of a stepper motor. It is provided with a manually actuated switch for controlling the phase sequence and time duration of the pulse trains applied to the motor. The operation of the motor by the motor tester, with the vehicle engine running, causes the engine computer module to generate a pair of pulse trains in response to the changing engine conditions. A pulse train monitor, plugged into the output of the engine control module includes a pair of bi-polar LEDs, one for each of the pulse trains generated by the engine control module. The bi-polar LED for each pulse train will alternately flash without both LEDs being off at the same time in response to an uninterrupted pulse train.
