Inovação no diagnóstico automotivo: como o Osciloscópio melhora a análise de componentes mecânicos frente aos scanners automotivos

Abstract

This work explores innovation in automotive diagnostics by comparing the effectiveness of oscilloscopes and automotive scanners in analysing mechanical and electronic vehicle components. Through an experimental methodology, tests were conducted on three distinct vehicles, simulating failures in the tone wheel, engine timing, and ignition coils. The results show that automotive scanners are effective for quick diagnostics based on fault codes (DTCs) in OBD-II systems, but have limitations in detecting subtle mechanical issues or in pre-OBD-II vehicles. Conversely, the oscilloscope excels in precise, real-time signal analysis, identifying intermittent and complex faults undetected by scanners. The integration of both tools is recommended to enhance diagnostic efficiency, accuracy, and reliability. This study contributes to the technical advancement of the automotive sector, emphasizing the importance of professional training and the adoption of complementary technologies in modern workshops.
