Nice video brother! Thanks for the lesson

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 like how you explained the parallel resistance

Very good diagnose and only parts renewed that are broken !

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.

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

DiagnoseDan.. Awesome video. Excellent demonstration and explanation of the Can-Bus system..

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

Your channel is excellent Dan! Thank you so much for putting your time into sharing this information so cogently.

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?

Excellent video. Wonderful analogy with the resistors and the bridges.

You are king of the Can Bus System. Very good lesson bro.

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 explanation of the can I've come across here.

Your bridge analogy showing twice as many people can cross is epic! Subscribed!

Hi Dan, really found this video useful. It is a pleasure to listen to someone who is so enthusiastic about their subject, and will carry out a proper diagnosis, rather than just replace parts, at the customers expense!

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

Hi Dan, yet again it's brilliant to see you work! I've been on a can bus course but your explanations were much better! Very interesting and educational and some very good testing methods, thank you for your time, Paul. Looking forward to the next one!

Top-notch expert and a great teacher to boot:)Dan, you are a Godsend!Having watched just a handful of your videos, I have learned bunch of pretty useful stuff already thanks to you!Love and respect!Although I am not a car guy I do find your diagnosis methodology extremely helpful and applicable to other areas.

I'm telling you that this is the most easy to comprehend lesson on canbus operation and troubleshooting that I have seen to date. Thank you and please never stop!! I just added it to my saved playlist for future reference. You've become one of the top automotive guys on KZfaq and I wish you the best in the future. The cool thing is all my favorite teachers are here and you all just add to each other's lessons. It's getting better all the time!

Best explanation on CAN network I've seen so far! Thank you so much

Fantastic video! You explain things so well it's very easy to relate to what is going on. I've only recently found your channel and really appreciate the effort you have made putting these videos together, you have some fantastic content!

Despite having nearly twenty years experience in the job, I’ve watched many of your videos, I always feel like I’ve learned something or been refreshed. On this merit no matter how familiar the problem I’m always compelled to watch to the end. Keep up the good work, every credit

I am so glad I found this channel. You explain electrical extremely well. Very precise, and you break the information and application down, in a very easily understandable way. Thanks Dan!

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

Great video Dan with clear and concise information with easy to follow procedures. Keep up the good work! 😀👍

subscribed!this guys has no BS.only clear,simple straight to the point explanation.

A lot of people, like teachers when you were at school can talk to you all day and it goes in one ear and out the other! Then you get guys like this, every word he says sticks in my head, i think it's a gift lol, keep up the good work Dan!

Great video! And well explained. I think a lot of people will benefit from this. Thx! 👍

You and Scanner danner are the best I hv really learn alot of diagnostics from you guys GOD bless you guys thks.

Some guys are good but are simply not good at explaining. Others will not share their knowledge or don't have the time. Others are just too boring. You don't fit in any of these categories and I would like to thank you for taking your time to share your knowledge.

Best ever approach, argumentation and solving a car problem, thank you.

Great video Dan! brilliant descriptions easy to follow! good job!!

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.

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

Sir, I have no words to explain. Mesmerised with your session. Such a detailing

Diagnose Dan fan here! thank you sir for taking your valuable time to teach us. You're very thorough and what I really like about you is that there is no jumping around or say something and take it back or have to reword it. Your very clear and very easy to understand and make it easy to grasp what you're teaching. Sir you are the very best! Please please please keep sharing! Virgil in Delaware

Great work as usual Dan ‘ I use to be a Volvo technician and can bus came out as I remember in about 1999 ‘ to 2000 and did confuse people’ but as long as you stick to the basic test it can be straight forward to diagnose what’s wrong’ great video as always

Great video Dan! The most difficult thing is to explain difficult stuff in accessible manner. You nailed it!

Came back and watched this again for the second time for a refresher. Great lesson. The bridge explanation was easy for me to understand. Thanks Dan

Brilliant and a very gifted teacher,Thank you Dan!

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.

Perfect - Clear and precise descriptions - Especially the bridge one for resistance, I won't forget that one

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

Awesome case study Dan, love the bridge analogy 👍 The timing couldn’t be better, my CAN101 video will be released to non patrons tonight 👍 Steve.

Excellent video! That has to be the fastest can fault diagnoses ever!

Thank you guy! I'm learning English and CANBUS and your English is very clear and slow! Your video taught me a lot!

Thanks for the video, Dan. For the students like me which have just entered this field, it's easy to understand the concepts. Please make such kind of videos so that we could have a hands-on experience.

thanks for a this just found your channel, been a fitter for 30 years never to old to learn

You have to make more videos dan!! Your level of explanations and diagnostics is on par with scanner danner and maybe even better! Truly a treat to watch ur videos sir. #Welldonesir

I've discovered your channel recently and i would like to thank you for your work. I would love to see your work collected in a Diag 101 manual or something like that, it would be extremly helpful for everyone interested in learning. Keep up the good work and greetings from a country where your knowledge is making the differnce between a disconnected CA module connector because the car starts again but with a missing feature and a replaced door handle but a fixed problem. Thank you!😊

Thanks Dan, very easy to understand the way you explain, not many people has this ability to teach, you have another member to your list, thanks again.

Thanks Dan wonderful training class! Only Keith de fazzio gets lucky everyday !!! Cheers sandy

Awesome video and very well explained, you are a natural at this

Hi sir Dan I love the way you approach the symptoms ...Awesome!

Very nice practical application of CANBUS diagnosis! I’ve been reading up on faults etc., but this helps a lot!

Thanks for that...its one of the easiest to understand videos about canbus ive seen and looking at the big names in youtube repair videos that are comenting on your videos you must be doing something right...you have a new subscriber

I can't recommend your videos enough! Thank you so much for your efforts! The CAN BUS explanation is pure gold!

Thank you. A very clear description of how a can bus system works.

Dan ,you are magic wand,,,,,, car fix,,,, .thanks again

Great video Dan! The system was so well explained I had to double check to make sure it was actually you speaking. lol

Diagnose Dan the Wizard of Automotive Diagnostics. Thanks for this brilliant tutorial on Can- Bus.

Absolutely superb training video. Thank you Dan

Great direction with the cluster codes. I like the simple process you take. Pick a system, and stick to, which is better than jumping back & forth between systems. You truly break down the back probing too. Impressive. Good to show how to do testing properly. Another thing I've noticed is the clarity in your schematics. IDK which information service you use, but I think other services should take note. Another great video! 👍

Those 120 Ohm resisters can get you if your not sharp!! Excellent illustrations Dan!

Dan, you are concise and brilliant. Yourself and Frank Massey from Autodiiagnose here in the U.K. Are the go-to guys for my own personal tuition. I am actually a BMW tech and enjoy your work.

WOW!!! I am impressed! I have been working on Mercedes-Benzs for 4 years now and these are the theories taught to me in online training, but it is so very different to see it put into practice. You Sir, are a master of your trade!

great video very well explained. thanks for sharing..

BEST CAN BUS AND CAN BUS RESISTORS EXPLANATION EVER MADE!!!!

No better teacher on line. Thax Dan for the CAN Bus education.

Wow! I can collect 100 electrical engineers that doesn't know about bus reflection and termination.. You are great!

Brilliant diagnosis and explanation of the CAN bus system, Dan! Did you have to progrm the new module in or was it plug-and-play?

In the network engineering world we call "echo" signal reflection and the twists are to prevent cross talk with other pairs (which would be the same as interference from another inductive load). In the old day of thin net we use to use terminators at the end of the run for the exact same reason.

Sir I have no words to say about your greatness & for your way of explaining. Thank you so much..

youre a good for showing and explaining demonstraion on problem solving diagnostic procedure good job bro!

Best video so far thanks very much ! scanner danner was here for a lesson what !

Fantastic video, clear and detailed! Great explanation with the slightly higher voltage on the waveform with the ABS module unplugged. Will you be doing any more CAN related videos?

This is something else, got found you by the dead audi video that had been uploaded just recently, but searching you channel, I found this video and it is amazing, just what I needed. Thank you!

this is by far the most entertaining guy in the online mechanics world...its just so captivating...

thanks man we need more can bus malfunction

Excellent, thank you

Dan you are the man. Ive never found anything that was so easy to learn and informative as your video.

Best explanation I've seen yet! I've steered clear of these things because the explanations usually were a bunch of technobabble. Some of the stuff where they converted a BMW 5 series to Electric makes a lot more sense now. Thanks Dan!

do you have a background in electronic engineering? I have been to a lot of classes & watched a lot of videos(for techs-not the backyard mechanic). awesome explanation. you clarify the operation. thank you!

Awesome video Dan and even i could understand it. Dan is still the MAN.

One of the best technicians that i used to know

Excellent video!!! You got the talent and, more important than most believe, the pedagogical touch!

Just one question, don't you need to code the new module in order to make it work properly? Provide it with correct vin number, type of transmission, stability control version etc? Or is it separate subject on a separate video? Anyway good job, keep it up :)

Oops, I had a question Dan and forgot to mention it in my previous post. If the ABS module was unplugged and it didn’t make any difference, do you typically plug it back in and move to the next module? Or do you leave it unplugged and move to the next module? The reason I’m asking is when there is a possibility of more than one module fault on the bus. Thank you!

Top notch stuff right here, Dan is doing the automotive community is Solid

Watching these older videos shows how much you’ve grown. You are very stiff in the older videos and much smoother and personable later on!

Great explanations!!👍👍👍 got my sub

hi great video one question if the abs module was faulty why was the abs light not on

You are the best!Slow speaking and show all in details .Thanks from Russia.

Excellent explanation on how a Canbus work .thank you again.

You're. Welcome. Friend

Hi, Mr dan can you help me for understand how can i check timing engine with oscilloscope (cranck shaft and camshaft position sensor)

i was looking trough KZfaq for can bus systems and it was bugling my head, but your video is very simple to comprehend, thanks for the lesson.

Bro, I love the way you explain the CAN in this video, many thanks, you are a very good teacher..
