Abstract
A power source failure detecting system for detecting failure in a power source for an electronic control system for a vehicle determines that a failure occurs in the power source and outputs a signal when the vehicle speed continues to be higher than a predetermined value (e.g., 40 Km/h) for a predetermined time interval (e.g., 10 seconds) and at the same time, the power source voltage is lower than a predetermined value (e.g., 9 v).
