???? Do you know how many types of signals there are in your car's engine? Do you know what a PWM, CAN BUS, Lin, SENT signal is, what Duty is, etc.? Do you know how the most common sensors and actuators in an engine control unit work? Could you read and interpret their signals with an oscilloscope to find out if they are working well or badly? ???? These and many other questions to be answered in this thirteenth chapter of the Automobile Electricity Course, where we are going to explain, with a car with the latest technology of 2022 and many practical experiments, How to read the signals of an Engine Control Unit If after the video you have questions, I encourage you to watch the previous videos (links below) and leave your questions in the comments ????
