Abstract: This paper describes Malek fault models by using equations model, and transforms the question of finding all consistent fault patterns about Malek fault models into finding the solution set of the system of equations. It provides a typical example and academic foundation for us to study the equation diagnosis algorithm about Malek fault models systematically by explaining how to find the solution set of the system of equations and to get the diagnostic results about Malek fault models through using an example
