This video is part 2 of CAN-BUS diagnosis. In Part 1 I explained the C-CAN (High-Speed CAN-BUS) and how to diagnose that network. In part 2 (This video) I explain the B-CAN (Body CAN or Low Speed CAN-BUS). I Explain what B-CAN is, where you can find it on the car, I explain the wiring diagram, the I show you the main points of the B-CAN to perform the diagnosis, I test the B-CAN with a multimeter, the I show you how to read the B-CAN waveform using an oscilloscope. Then I set a fault on B-CAN to show you how network functions in case of any fault.
