FIELD: testing and diagnostics of microprocessor control systems for controlling motor, possibly diagnostics of automobile pickup faults.
SUBSTANCE: method comprises steps of detecting faults of pickups on base of occurring of resonance frequency of pickups, of electromagnetic irradiation amplified by 2 - 4 times and more, additional shift of fronts of pulse signals, phase shift of harmonic signals passing through pickups circuits, presence of sub-harmonic oscillations, change of amplitude-frequency characteristics, changed relation of incident and reflected waves, occurring of signal differentiation effect and response of added parameter pickup.
EFFECT: enlarged functional possibilities of method and apparatus due to detection and registration of latent defects at operation of pickups.
