Very nice video and much more information in this and you explain much batter sir may i connecting with live call OR passenger if this possible i am very thankfully to you i am waiting your answer i am senior auto technician my Email nadeemahmed1809@gmail.com what's app no 00923009661809 again THANKS to you sir
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 don't know what to say really, just that I'm very honored. Respect that you are trying to learn about the can-bus system at 79! Another reminder that we are never finished learning in this industry. An honor having you here Sir, thanks for watching my video's it's appreciated Micheal👍💪
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.
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.
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
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?
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.
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
For me, living across the pond that has a 2006 Ford Fiesta ST that has the dreaded abs and parking brake lights on dash and no speedo, and no communication on canbus, and basic auto electrics knowledge, this has been a brilliant lesson in diagnosing!! Hope it's not the abs module.. Ford want £800 ( $1035 ) for new one!! .. All the best Dan...
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.
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 Dog..........
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
I work in the industry, I'm an older mechanic and haven't kept up as much as I should due to a lot of life issues. This is hands down the bect video on CAN bus I have ever seen. Thank you for it.
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
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!
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
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!
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! 👍
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 UA-cam 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!
Pine Hollow Auto Diagnostics, these modules can be repaired. So i replaced it with a repaired one. It only needs coding, it doesn't need to be programmed!😁
Dan got called in on a 2012 VW Touraug the other day for a parking brake fault. The guys had done rear brakes and rotors, the parking brake is drum setup with electric actuators , they had not touched this during the brake job. Apparently before the brake joe they should have gone in and recorded the Coding number and mm clearance stored in the module, was not able to restore function. Trip to the dealer , tough system
This makes so many things clear for me. I am currently working with CAN bus for the first time and I was looking for videos on how it is implemented in industrial setting like a car. Thank you so much for your fantastic explanation and step by step diagnosis of the fault and subsequently rectifying it. You are awesome!
Simply Diagnostics, Thanks Steve! Looking forward to your Video! What do you think of my drawing skills🤣🤣 Did you see the detail on the little green people😁
This video is fantastic. I worked on a vehicle recently with communication issues between the PCM and TCU and needed a refresher on diagnosing these networks. I'm amazed at how thoroughly you covered this topic. Thanks!
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
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!
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.
I work at an Intle location fixing the machines that make computer chips. Your videos help me to understand my machines as well as my German auto. Thanks for the great videos!
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
One of the best instructional videos i have viewed on UA-cam, an simpler expalnation for the 120 ohm bus terminators, just show a 120 ohm resistor on the DVM than add a second 120 ohm in parallel to show m120 + 120 ohm in parallel is 60 ohms
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
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!
Thank you very much for this video. I’ve been facing U012587 issue on my 2021 toyota Sienna and no one is able so far to figure out the problem. 😢 Decided to watch some tutorials and try figuring out the problem (so maybe I could fix myself) and your videos with very detailed explanations (and examples ) are AMAZING! 👍👍👏👏🤩🤩
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!
I'm new to this technology trying to get a hold of it. I thought the video was excellent. It was pitched at the right level, well commentated throughout with easy to follow procedures - all I need is to learn how to use an oscilloscope!! Thank you so much.
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!
I was an auto tech for over 40 years, retired in 2014, and spent many times at the manufactures training center. Could never fully understand C-Can or Bus until now. I just wish that you, or someone like you, had been my instructor for all those 40 years. EXCELLENT VIDEO.
Hi great question! You paid attention! Consider liking my Facebook page! I shared a picture there after this video. It turned out that another shop disabled the ABS light🤣🤣
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!
Love your channel, I almost finish Automotive school. This part of the diagnostic is an advance class not cover in the school. I am glad I found your channel. there is vast information to cover related to network communications and other parts of diagnostic. In my opinion, you are professional with a great knowledge of diagnostic. Diagnostic is the area most technicians lack experience or knowledge.
They say that a good teacher is able to make a complicated subject seem simple. The drawing illustrating the effect of parallel resistors was incandescent. It was like walking into the room labeled canbus, closing the door, wallowing in total darkness. Then along comes Dan. With a pair of LED’s. Download this video, and put it on all your gadgets, so u don’t lose it. I am
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!
Excelent video! Thank you! I Subscribed, allowed me to add (of course you know that but just for the subscribers) that also the twisted wires in a CAN line perform the function of creating a electromagnetic field all along and around the cables that does not allowed any (or very little) outside electrical and electomagnetic interference (noise) to the main signals. I also have a question Dan, can you please tell me in which of the CAN cables(CAN Low or CAN High) does the Middle CAN signal travels on? Thank you for the answer.
Sir I wanna ask you a question Sir if Abs making trouble in communication then if I remove it's circuit other modules should communicate or not ? Will scanner read other options like PCM and BCM ?
DiagnoseDan sir I'm an electrician and yesterday customer bring me a car Hyundai Elantra 2016 and the problem is abs and pcm BCM not communicating the indicator lights are on and rpm isn't working gear is not shifting properly he said he had an accident and after that the problem starts I check with multimeter the wiring is good from OBD2 to ECU I checked the ohms are 61.1 it seems also good I removed the abs circuit and tried to diagnose again but still same I opened the whole wiring from front side where the car damaged I got some wires cuted and grounds were broken I fixed it and then I tried to scan it again but still same the only module is communicating is airbag and it's showing the crash record code only I removed some 5 volt sensors like AC pressure sensor and coolant temperature sensor I thought maybe 5 volts are shorted but still no communication what should I do next ?
DiagnoseDan sir finally I have fixed it every thing is back to normal in car I found right front abs tire harness wire broken and crankshaft position sensor was bad the reason my scanner was not communicating to ECU was my scanner was outdated the car model I was diagnosing was elentra 2017 and my scanner supports only models till 2016 that was the reason it was not communicating then I used another updated scanner tool and everything was perfect by the way your videos is so helpful sir I appreciate it keep it up thanks for such good videos
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.
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.
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!
Nice video brother! Thanks for the lesson
ScannerDanner, Thanks Paul Not that you need it😉 I appreciate your comment buddy!👍
I really liked the "echo" analogy. It helped me. Seriously
Speachless just a fan of the two of you dans. God bless
@@ScannerDanner For me the 2 bridges was the aha moment. Need to do more studying on resistors and circuits.

Best channel on the net for graphics, info delivery and overall performance. 10 outta 10.
Tom OConnor, ha ha ha i feel like I'm on; Holland's got talent!🤣🤣.
Thanks! 10 out of 10 is not a bad score👍
One of the best videos for explaining how a Can-bus works and explaining why the resistors are in the network.
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

Reminds me of my childhood, when my dad took my hand and told me all about things in life ...
Thanks Dan!
Wow it's an honor!
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
It was in my head all this time🤣🤣
Best explanation on CAN network I've seen so far! Thank you so much
dalix1951 Thank you!😁
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 explanation of the can I've come across here.
Cam Smith Thanks that's a great compliment!👍
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
Thanx!👍👍
You and Scanner danner are the best I hv really learn alot of diagnostics from you guys GOD bless you guys thks.
Mwesigwa Joel, Wow that's a great compliment!😍
subscribed!this guys has no BS.only clear,simple straight to the point explanation.
Thanks for Subscribing, watch more of my video's and you'll see BS sooner or later🤣🤣
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.
I love to hear that sir, it's an honor to have you on board👍
Best ever approach, argumentation and solving a car problem, thank you.
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!
Paul Lane, Wow that's a great compliment! Thank you!😁
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
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! 👍
Thanks Cuba for the great comment, it's an honor. I use Hella Gutman wiring diagrams.
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 UA-cam 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!
I dare say this video is even better presented than Wells VE classes.
MikeP47 Ha ha Mike has got a Professional film set, i love his video's!
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?
Pine Hollow Auto Diagnostics, these modules can be repaired. So i replaced it with a repaired one. It only needs coding, it doesn't need to be programmed!😁
You should show the coding part too ;))
Pine Hollow Auto Diagnostics, I'll do a separate video on programming and coding, when a nice case study comes along😉
Dan got called in on a 2012 VW Touraug the other day for a parking brake fault. The guys had done rear brakes and rotors, the parking brake is drum setup with electric actuators , they had not touched this during the brake job. Apparently before the brake joe they should have gone in and recorded the Coding number and mm clearance stored in the module, was not able to restore function. Trip to the dealer , tough system
Gary Stephens and
This makes so many things clear for me. I am currently working with CAN bus for the first time and I was looking for videos on how it is implemented in industrial setting like a car. Thank you so much for your fantastic explanation and step by step diagnosis of the fault and subsequently rectifying it. You are awesome!
Your channel is excellent Dan! Thank you so much for putting your time into sharing this information so cogently.
Your welcome!
You are king of the Can Bus System. Very good lesson bro.
🤴🤣🤣👍
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.
Simply Diagnostics, Thanks Steve! Looking forward to your Video! What do you think of my drawing skills🤣🤣 Did you see the detail on the little green people😁
DiagnoseDan it was a beautiful picture 😂 but no clouds, sun nor birds 😂
Simply Diagnostics, Thanks for the feedback, i knew i forgot something🤣🤣
Your video is next lol...
This video is fantastic. I worked on a vehicle recently with communication issues between the PCM and TCU and needed a refresher on diagnosing these networks. I'm amazed at how thoroughly you covered this topic. Thanks!
Wow thanks!
Those 120 Ohm resisters can get you if your not sharp!! Excellent illustrations Dan!
Thank you!
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

thejoneseys, Wow that's Great!😉 Thanks for the comment buddy it's appreciated!😁
Dan, the methodical way you diagnose and the simple way you explain is amazing!👌 - Dr.Kamalendra , cardiologist , India
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.
FrugalPrepper's Garage & Garden, Thanks for the feedback!👍
I was just thinking how much it resembled earlier Ethernet implementations; 10base2, for example. Very similar.
Bro, I love the way you explain the CAN in this video, many thanks, you are a very good teacher..
Brilliant and a very gifted teacher,Thank you Dan!
Bill Maxfield Thanks for the compliment! It's apriciated!👍
Dan, if you can make this stuff clear to me, you,re home free brother! Great lesson!!!
Bill Maxfield 😁
I work at an Intle location fixing the machines that make computer chips. Your videos help me to understand my machines as well as my German auto. Thanks for the great videos!
BEST CAN BUS AND CAN BUS RESISTORS EXPLANATION EVER MADE!!!!
PreferredAutoPerformance Wow that's a great compliment!👍💪
Thanks!😁
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!
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
Lavoras Automotive, Wow you make me blush😁.
One of the best instructional videos i have viewed on UA-cam, an simpler expalnation for the 120 ohm bus terminators, just show a 120 ohm resistor on the DVM than add a second 120 ohm in parallel to show m120 + 120 ohm in parallel is 60 ohms
Great video Dan with clear and concise information with easy to follow procedures. Keep up the good work! 😀👍
stuzman Thanks!👍
approaching to retire as military mechanic and your videos motivates me to keep on going
Great video! And well explained. I think a lot of people will benefit from this. Thx! 👍
Dylan, i hope so! 😁
Excellent explanation on resistance....ive taken multiple electrical classes and that was by far the easiest ro understand
Thanks Dan wonderful training class! Only Keith de fazzio gets lucky everyday !!! Cheers sandy
sandy anderson, I'm going to ask him about his secret than😁😁
DiagnoseDan 🙈🙉🙊
New Level Auto, what's your secret Keith? Is it the aftershave your using?🤣🤣
Another good video. Well paced and methodical. Easy to understand the steps involved.
Thank you!
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
shauns auto repairs,Thanks for the comment buddy it's appreciated, and for Subscibing of course!😁
Thank you.
A very clear description of how a can bus system works.
Thanks for watching my video's it's appreciated!😉👍
thanks for a this just found your channel, been a fitter for 30 years never to old to learn
True, i still learn every day!
Dan you are the man. Ive never found anything that was so easy to learn and informative as your video.
Thanks!😊👍
Awesome video and very well explained, you are a natural at this
That's a very Nice comment Sir!👍
youre a good for showing and explaining demonstraion on problem solving diagnostic procedure good job bro!
Thanks!👍
Great video Dan! brilliant descriptions easy to follow! good job!!
Carl Wensierski Thank you!😁
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!
Dan ,you are magic wand,,,,,, car fix,,,, .thanks again
Arian Taria Wish that was true!😁 Thanks!👍
Great CAN explanation. Resistors are like the tensioners for communication lines, keeps the signals from bouncing 👍
👍👍💪😊
Great video Dan! The system was so well explained I had to double check to make sure it was actually you speaking. lol
Ozzstar Lmao😂😂 I can be serious sometimes! I just need to concentrate!😉
Thank you very much for this video. I’ve been facing U012587 issue on my 2021 toyota Sienna and no one is able so far to figure out the problem. 😢 Decided to watch some tutorials and try figuring out the problem (so maybe I could fix myself) and your videos with very detailed explanations (and examples ) are AMAZING! 👍👍👏👏🤩🤩
Best video so far thanks very much ! scanner danner was here for a lesson what !
tony pond Thanks!😉🤣🤣🤣
Great video Dan! The most difficult thing is to explain difficult stuff in accessible manner. You nailed it!
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!
stuzman, i would have plugged it back. The chance that you have 2 modules failing at the same time is not likely.
I'm new to this technology trying to get a hold of it. I thought the video was excellent. It was pitched at the right level, well commentated throughout with easy to follow procedures - all I need is to learn how to use an oscilloscope!! Thank you so much.
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!
mike gallagher , Thanks for the comment buddy it's appreciated!
I was an auto tech for over 40 years, retired in 2014, and spent many times at the manufactures training center. Could never fully understand C-Can or Bus until now. I just wish that you, or someone like you, had been my instructor for all those 40 years. EXCELLENT VIDEO.
hi great video one question if the abs module was faulty why was the abs light not on
Hi great question! You paid attention! Consider liking my Facebook page! I shared a picture there after this video. It turned out that another shop disabled the ABS light🤣🤣
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!
thanks man we need more can bus malfunction
No problem keep watching!
Love your channel, I almost finish Automotive school. This part of the diagnostic is an advance class not cover in the school. I am glad I found your channel. there is vast information to cover related to network communications and other parts of diagnostic. In my opinion, you are professional with a great knowledge of diagnostic. Diagnostic is the area most technicians lack experience or knowledge.
They say that a good teacher is able to make a complicated subject seem simple. The drawing illustrating the effect of parallel resistors was incandescent. It was like walking into the room labeled canbus, closing the door, wallowing in total darkness. Then along comes Dan. With a pair of LED’s. Download this video, and put it on all your gadgets, so u don’t lose it. I am
Love your comments Bill, i Thank you for that!😁
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!
As long as you interpret all the signals correctly at home,I'm sure you'll get lucky there too! LOL
Thomas EXOVCDS Ha Ha Ha Lmao Thomas. I'm having trouble reading the signals, unfortunately she didn't come with a manual.😉
You're doing fine... 2 kids, yes? =)
Thomas EXOVCDS, got lucky twice😂
Brilliant info Dan, most educational, why are modern car electronics such a nightmare for mere mortals!
Never forget that it's all made by normal people just like you and me. So how complicated can it be?😉
Excellent, thank you
paul tomasetti Thanks for watching!👍
great informational video. This is one of The Best You tube diagnostic videos!!!!!!!!!!!!! There are not many mechanics that can do this
Wow thanx😀
Excelent video! Thank you! I Subscribed, allowed me to add (of course you know that but just for the subscribers) that also the twisted wires in a CAN line perform the function of creating a electromagnetic field all along and around the cables that does not allowed any (or very little) outside electrical and electomagnetic interference (noise) to the main signals. I also have a question Dan, can you please tell me in which of the CAN cables(CAN Low or CAN High) does the Middle CAN signal travels on? Thank you for the answer.
Argeny Sandoval Thanks for Subscribing!😁
From now I worship you
Awesome vedio thanks

Sir I wanna ask you a question
Sir if Abs making trouble in communication then if I remove it's circuit other modules should communicate or not ? Will scanner read other options like PCM and BCM ?
A RAHMAN, Yes with the bad module removed from the network you should be able to communicate again!😉
DiagnoseDan sir I'm an electrician and yesterday customer bring me a car Hyundai Elantra 2016 and the problem is abs and pcm BCM not communicating the indicator lights are on and rpm isn't working gear is not shifting properly he said he had an accident and after that the problem starts I check with multimeter the wiring is good from OBD2 to ECU I checked the ohms are 61.1 it seems also good I removed the abs circuit and tried to diagnose again but still same I opened the whole wiring from front side where the car damaged I got some wires cuted and grounds were broken I fixed it and then I tried to scan it again but still same the only module is communicating is airbag and it's showing the crash record code only I removed some 5 volt sensors like AC pressure sensor and coolant temperature sensor I thought maybe 5 volts are shorted but still no communication what should I do next ?
A RAHMAN, Scope the can-lines And check what's going on. Also check the power and grounds on the dlc
DiagnoseDan sir finally I have fixed it every thing is back to normal in car I found right front abs tire harness wire broken and crankshaft position sensor was bad the reason my scanner was not communicating to ECU was my scanner was outdated the car model I was diagnosing was elentra 2017 and my scanner supports only models till 2016 that was the reason it was not communicating then I used another updated scanner tool and everything was perfect by the way your videos is so helpful sir I appreciate it keep it up thanks for such good videos
A RAHMAN, Great work!👍👏💪
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.
Very nice and useful! Although I believe that 32 people are losing money cause of your fixes (dislikes)
🤣🤣Thanks for watching!
You're a much better teacher than my University professors. I salute you sir. Cheers!
Thank you Sir!
You're. Welcome. Friend
Mechanic Technician Repair Thanks!
Sir, I have no words to explain. Mesmerised with your session. Such a detailing
Hi, Mr dan can you help me for understand how can i check timing engine with oscilloscope (cranck shaft and camshaft position sensor)
Gharbi Mecatronicien, i did this in some of my video's! Did you watch those?
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.
Great explanations!!👍👍👍 got my sub
STEEVE DAVID Nicolas, Thanks for Subscibing and for the nice words!👍
i was looking trough UA-cam for can bus systems and it was bugling my head, but your video is very simple to comprehend, thanks for the lesson.
Your bridge analogy showing twice as many people can cross is epic! Subscribed!
You are the best!Slow speaking and show all in details .Thanks from Russia.
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!
this is by far the most entertaining guy in the online mechanics world...its just so captivating...
