Hello Dan. I must say this is the best demonstration I have yet to see regarding Can diagnosis! only a select few people I have found In my search of education have been able to break down what at first seems to be overwhelming complicated syestems/scenarios into it's most simplest form Making learning fun and injoyable. You sir are the real deal! Few and far between! We are all blessed to have you sharing with us. Thank you
Wil.

Dan, without question you have the "Gift" to impart knowledge!   No question about it -  your presentation was a "10" all of the way!   Having worked, and taught,  a lot of Aircraft Avionics, I really love to watch and listen to someone who can make a difficult system very easy to understand.   You are one of the best I've ever seen or heard.Many thanks for helping me understand (at least on a cursory level)  the CAN buss - just learning how all of "this" fits together. :)   At 79 years of age, I'm just now learning how to work (somewhat) on my vehicle ('07 Lacrosse, 3.6 Ltr.)  I'm gaining some ground, and I'm sure your tutorials will be a great assist.   Can't thank you enough.

I have always sent vehicles with canbus issues to the auto electrician down the road.
After watching this video and having the mysteries uncovered I feel confident in diagnosing the next one myself.
This also reaffirms that information is key to success.
You CAN teach an old dog new tricks, you just did.
I am a tech in my 60s and still enjoy learning, thank you for this information.

I'm learning a ton from these oscilloscope users such as Dan and Paul. I will be getting back into auto repair to supplement my retirement in 2 years. Things sure have changed since I quit wrenching for a living in 1985! Sure I still repair my own vehicles but never knew about all the uses of the oscilloscopes and the existence of this "can bus" system. There is so much for me to absorb but I'm loving every minute of it. Thank you for your time in teaching this old

Reminds me of my childhood, when my dad took my hand and told me all about things in life ...
Thanks Dan!

Dan, the E39 is known for ABS module problems.. It also causes the Spittronic gearbox to force the car into LIMP mode. (My own e39 also has the same problem.) But you explained it in more detail, than most Auto /Mechanics "knowing" precisely what is going on, behind the scenes, so to speak.

This man is a ledgend. I am in my last year of technical specialist. And I still learn a lot from this guy. Not so much what is already explained in text books. But just things to look out for and some handy tips and tricks

Best CANBUS related fault trainning video I have come across outside of dealer training. Well done was a great refresher!

[saitamapunch]

WoW.. Where has this explanation been all my life lol. I don't think too many automotive techs out there can understand or appreciate this great explanation. Great job sir

[clevelandrichards]

This was a welcomed class for me, For 30 minutes I was back in class with a great communicator and teacher. Thank you Dan, Yu de man. Cleveland cads223.

[guayaco-dmvu]

Dan..If you ever quit fixing cars you can be an excellent teacher ...
Your way of explaining things it's just entertaining n educational...all the best Dan

[lemmykilmister]

Best explanation of the can I've come across here.

[natet]

One of the best videos for explaining how a Can-bus works and explaining why the resistors are in the network.

[wysetech]

Extremely well done! I learned a lot from your video and i'm 68 years old. Who says you can't teach an old dog new tricks.

[dricklorenz]

Another good video. Well paced and methodical. Easy to understand the steps involved.

[fieldsofomagh]

Best channel on the net for graphics, info delivery and overall performance. 10 outta 10.

[WCB]

I dare say this video is even better presented than Wells VE classes.

[lameckarika]

Damn man! I have watched 5 of your shows religiously and am now addicted to the simplicity of your explanation and the immense knowledge you posses regarding in-depth diagnosis. Your approach to problem resolution is one that every mechanic should possess. I have gone to dealerships and have been severely disappointed with the so-called diagnosis gurus. Keep on posting more. Is there any chance you can post a description of the software you are using currently?

Absolutely awesome video, I actually had a trouble car a while ago, it was a no start, and no comms with the scan tool, so I hooked up the scope and saw abnormal can signals and lack of, so I just disconnected the abs randomly and bang the car ran and signals came back, awesome
