Finding CAN Bus Signal Errors

This video shows you how you can use the PicoScope software to identify specific points in your CAN bus voltage signals that may result in a failed message. If you are looking for an intermittent or noisy signal, this tool can be helpful in quickly identifying problems.

Also I don't know if you know this but the local community college that I am attending actually uses some of your videos for the automotive electrical course I am taking. In fact, I look forward to hearing your voice as I know I'll be able to follow your teaching.

I don't know if you'll ever see this but I just wanted to let you know that I am a 25y.o. automotive technology student working part time and going to school full time and I have found your videos to be incredibly helpful to me! I am very grateful for these videos and your expertise and so appreciated.

Thanks for all your great videos Justin. Sad to say I don't get my scope out as much as I should. Since i discovered your channel I've got a renewed determination to do just that. I've been a tech for over forty years and my first scope was as big as a car and really only focused on ignition waveforms. Then came my Fluke 97 and it was great (still have it), then a cheap USB scope for a hundred bucks and really splurged when I bought the 4 channel Pico scope a few years ago. Just lately I bought a Micsig STO1104C which I've been using much more lately because it's a stand alone unit. i got kinda tired of dragging out the laptop and pico scope even though it's got a much deeper memory than the Micsig.

Awesome brother. Keep up the great videos!

That was very informative, thank you.

Is pico the only scope that can detect these errors or is it just a matter of settings? Great video too.

New subscriber here, this is an excellent channel! Once you've found a reoccurring issue can you cross reference the identifier with some sort of lookup table to find the control unit that is causing problems?

I actually enjoyed that...very well explained thank you

Hi, I've been searching the internet for hours looking for a solution. I have a problem with the cambus. Steering wheel controls don't work, and when I turn the key the radio won't turn on. gives me error (U2101-00 canbus maximum configuration list not programmed). I tried unplugging the battery for 1 hour but the problem is still there. I was wondering if you had any idea what this error is and possibly how to fix it. I hope you answer me since the video is years old. I thank you in advance.

Thank you sir, what do you think about an automotive oscilloscope that has 10 Mz bandwidth, 40 Ms/s sample rate to analyse can bus fast canbus, and all car's sensors. It's AVL DiTEST SCOPE 8400.

Somebody built a website that decodes and analyses CAN messages for free. Haven't tried it yet because I don't have CAN to USB, but ordered one from Amazon to test. Sounds very promising to me.
The website is CAN2SKY.com
Maybe try it and compare to the Pico scope software.
