Construcción e implementación de un banco didáctico de un sistema de inmovilizador con trasnponder para la Escuela de Ingeniería Automotriz.

Abstract

The construction and implementation of the education Bank of immobilizer transponder system, aims to provide a learning tool for developing knowledge an practice in immobilizer ignition and safety anti-theft systems in a vehicles. The process began with the collection of information, principles of operation of the analysis of efforts , wiring diagrams an electronic the metallic structure was prepare, relying in this one the board and its components properly mechanized, the power line structure allows the communication with each of the elements. The bank incorporates a system of injection processor 1 AVP communicates with the processor Inmobox that by means of an antenna, extracts the code of the key, if the code is correct the Inmobox that by means of an antenna, extracts the code of the key, if the code is correct the Inmobox sends a sign of acceptance to the ECM to active the relay of fuel and the negative pulses for the bobbin and injectors, if the key in not correct one, the ECM in blocked an the ignition is cancelled. In the testing process, with the information transferences, the fault codes that are read on the computer were extracted, while in ignition tests is was possible to verify the correct programming since with a not codified key the system does not answer, in the analysis of waves reflected on the screen of the bank, the communication results are confirmed between its two processors, to establish the failure state or correct functioning of the immobilizer system. It is recommend to follow the process planned in the user manual, which sets a sequence for the correct handling of the bank, didactic teaching an maintenance of the same.
