System, server, user device including a user interface and road control device that are used for training vehicle maintenance technicians by simulating faults in the electronic communication system of the vehicle

A server dedicated to the training of vehicle maintenance personnel through fault simulation in an electronic communication system of a vehicle, wherein the server communicates with one or more wire controllers to enable or disable faults in one or more wires, said faults enabled in the wires comprise:

• opening the wire or an insertion of parasitic resistance in the wire or short-circuit between the wires or low resistance between the wires or reversing signals or invariant signal or null signal or attenuated signal or amplified signal or pulse-width modulated signal, said server sends and receives user information via instructor device comprising an instructor application and a learner device comprising a learner application, and said server is configured to manage users with different access rights in parallel.

A wire controller dedicated to the training of vehicle maintenance personnel through fault simulation in an electronic communication system of a vehicle performed through a switching mechanism capable of diverting a signal coming from a wire of the vehicle to a circuit that produces a desired fault, whereas commands for selecting the desired fault are transmitted by a wireless communication system, the wire controller comprising:

• a plurality of wire control modules configured to control a plurality of wires of the vehicle, the plurality of wire control modules comprising customizable logic for the simulation of a plurality of faults, wherein the customizable logic is configured to implement the faults by the modification of the signal by pulse width modulation and the modification of the signal by a variable resistance;
• and
• a microcomputer configured to control the plurality of wire control modules.
