In this video I explain everything about the CAN-BUS diagnostic on Ford. For this video I use a Ford Fiesta that has two types of CAN-BUS Network (High-Speed & Medium Speed). So, in this video I start by explaining each type of CAN BUS on Ford, and what units are connected to each one of them. I continue by explaining the wiring diagram to see how we can find the network on the car. Then I explain how to check the CAN BUS resistance and voltage with a multimeter, and later on we see how to read and analyze the waveform on the CAN BUS and for that we use an oscilloscope to read the waveform.
