We look at diagnosing multiple faults on the low speed K CAN network. If you want to know how to diagnose CAN bus faults, I suggest using an oscilloscope, check out this PicoScope automotive training video.
In this video, we look at how to diagnose CAN Bus faults using the PicoScope 2204A oscilloscope. We also look at CAN bus waveform analysis to help you identify CAN bus problems. It can be complicated but this simple CAN Bus Fault Diagnosis video we help you identify the difference between high speed and low speed CAN Bus networks and how to set up the oscilloscope to test CAN Bus. We use the PicoScope 2204a oscilloscope to analyze a CAN Bus signal while different faults are installed.
