Abstract
A fail-safe device in an electronic control system for an automotive vehicle comprises a monitoring device for detecting failure of the CPU and generating a signal indicative of error in the CPU, and a storage device for outputting data to replace the CPU output while the CPU is operative. Thus, the control system can work for controlling a vehicle control device even during CPU failure.
