Abstract: The present invention relates to ECU monitoring system and method. The ECU monitoring system includes: an ECU that includes an input interface unit, a computer unit, and an output interface unit; a storage unit that stores a normal input signal in input signals inputted to the input interface unit, for each inputting, and stores a normal output signal outputted from the computer unit, for each outputting; a comparing unit that calculates a compared difference by comparing the current input signal inputted to the input interface unit with a previous input signal stored in the storage unit, and outputs an alarming signal showing the that current input signal is an abnormal input signal, when the compared difference is out of a predetermined range; and a circulator that receives the output signal from the computer unit, provides the output signal to the output interface unit when the output signal is a normal output signal, and provides a normal output signal stored in the storage unit to the output interface unit, instead of the output signal outputted from the computer in response to the abnormal input signal, when receiving the alarming signal from the comparing unit.
