Manual de diagnóstico, entrenamiento y solución de fallas empleando instrumentación automotriz en un vehículo marca Chevrolet Optra 1800 cc

Abstract

To create the Chevrolet Optra 1800 cc Advance diagnostic guide as a training resource for technicians or students seeking to understand the operation of the electronic fuel injection, as well as the function of the ECM and troubleshooting possible fault codes, this manual has been developed. For the development of the manual, automotive tools such as the scanner, oscilloscope and multimeter were used to obtain data at different engine revolutions. For the correct use of these tools, a guide was prepared which explains how to use each of them, thus benefiting those people who are not up to date in their use. Several fault codes (DTCs) were triggered, which caused a malfunction in the injection system. To read these codes, it is important to have and know how to operate a scanner, which provides information about the problem that is occurring so that it can be corrected and erased. Finally, the data obtained from the Chevrolet Optra 1800 cc was tabulated in comparison with other models or manufacturers of light cars, to validate the diagnostic manual.
