Abstract

The generator of an automobile supplies electric voltage and current for various electric components. The supplied voltage can be changed by sudden variation of the electric load. The voltage was controlled by independent power supply in the study. The TPS and APS signal was changes as the voltage of the power supply. The ECU output voltage and OBD signal voltage was changed also as the variance of the power supply.
