Multimeters, oscilloscopes and scanners for precise measurement, reading and analysis of electrical circuits to provide the optimum solution. Engine ECU reprogramming, meanwhile, offers the possibility of optimizing vehicle performance and reducing pollutant emissions by adjusting engine parameters. The integration of these technologies, their impact on the automotive industry and the skills needed to master them are proving essential for the management of vehicle fleets increasingly equipped with these on-board systems, making future vehicles more intelligent and reliable.SensorOnboard SystemsComputerActuatorThesis
