Diseño y construcción de un banco de pruebas para evaluar el funcionamiento de los sistemas de programación de llaves y módulos inmovilizadores de vehículos

Abstract

This project establishes the creation of a test bench to evaluate and diagnose the operation of vehicle key programming systems and immobilizer modules, to carry out this project the components that will be used are from a Renault Logan car year 2009 the The parts to be used are the UCH module, which is the central unit of the passenger compartment or central unit of a multiplex system, originating from the Renault system, tachometer or instrument panel, key with chip, the ECU, which is the electronic control unit, antenna of the immobilizer module. which receives the signal emitted by the key. In the first place, the diagrams will be analyzed to be able to bank and make the connection of each cable of the computer and the UCH module, followed by tests to verify that the connection of the ECU and UCH module are working correctly. Next, the programming of the key will be carried out with the help of a test bench with which we will extract the pin code of the keys and it will be programmed with the UCH module, to carry out the programming we have to turn off the ignition, we proceed to configure the key depending on the keys the test bench takes a certain time, when the keys are removed the ignition will be deactivated once the ignition switch is turned to on the ignition will be activated.
