Abstract
An electronic control unit charges capacitors of sensors to produce idle phase waveforms having different waveform parameters assigned to the sensors, and transmits nothing between the signal phase time periods. Each sensor detects the idle phase waveform parameter of the capacitor. The sensor responds to the ECU during the signal phase time period, if the detected parameter corresponds to predetermined waveform parameter.
