Finding CAN Bus Signal Errors

[@judahkraft2898]

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.

[@JustinMillerAutomotive]

Thanks for sharing that. It means a lot. I am glad that the videos are helping!

[@judahkraft2898]

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.

Glad I ran into this channel.really like the breakdown. Just like to know and figure out why and how things work.

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.

Great video 🎉

[@alanw5879]

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

[@jeffreyherbert91]

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

[@wyattoneable]

That was very informative, thank you.

Thank you for information...

Nice work. 👍

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?

thank for video

[@hichamsaid9472]

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.

[@JustinMillerAutomotive]

It could work, but you would need to set your scope to a very short time base and you may only be able to capture 1-2 data frames at a time.

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.

[@JustinMillerAutomotive]

It is really hard to diagnose the car remotely. I can only guess. What type of car is it?

[@salta199]

@@JustinMillerAutomotive I went to my mechanic. he told me that it should be the fault of the display that gives the radio information. now i am waiting for the replacement display. 🤞 thank you so much for your reply

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.

[@JustinMillerAutomotive]

Thanks for the suggestion. I am curious now!
