On-Board Malfunction Simulations on Vehicles that Are Equipped with Electronic Control Systems

On-board malfunction simulation consists of generating controlled malfunctions by transmitting, through sensor connector, a signal of a certain variation/ wave to the electronic control unit. Thus, the control unit will interpret that the monitored system has a malfunction. The main advantage of this method is that it allows the simulation for a wide range of malfunctions without requiring complex operations when changing from one type of malfunction to another. Also, this method (nondestructive type) exploits the technical potential of on-board diagnosis systems which fit modern vehicles and it allows to use the same devices for all types of simulated malfunctions.
