I have never seen a better explanation of the CAN-BUS, I am extremely grateful...!!!

I don’t really work with cars, but I’m an IT trainee. Watching this video was really informative, interesting and you explained everything very well. Thank you so much, I have always wondered how the can bus works exactly. Keep up the good work!
And also now I understand why the ford focus of my sister in law was acting up with weird and seemingly unrelated error codes when the solder joints of her cluster broke.

Thanks, I started working on cars setting point gaps and using a timing light. Now I work on adaping modern engines into older vehicles. The overview was helpful.

THIS CASE STUDY HAS VALUABLE COMPLETE INFORMATION TO HELP IN APPROPRIATE DIAGNOSTICS CAN SYSTEMS IN A PROFESSIONAL MANNER, THANK YOU. WELL DONE.

CAN BUS stands for Controller Area Network Bus in case anyone wondered.

Very informative and helpful with clear explanations about Can Bus

Your explanation about can bus is awesome... ❤️❤️❤️ I got some new points from your this video. thank you...

This is video is absolute gold! Such great information and the way you present this information is very easily digestible for dummies like myself. Thank you for making this video you good man you!

Grate material. Don't stop doing this. Thank you👊

Great info especially about the termination resistors.

I just subscribed. You are the best ❤🎉. This video deserves a billion like 👍. Good Explanation

I enjoyed this video and learned a lot, just subscribed to this channel 😊😊

Very nice explanation... thank so much and keep up the good work

words are not enough to describe your amazing videos .A New subscriber from Iraq.😍😍😍

I liked your video it has a good explanation for how the basics of this can bus system works. I was hoping that you might have an example of a failure or what really happens when one of these modules is bringing down the can and how you find out which one that is. I did need this though as i have very limited knowledge on a can bus system and working with electrical problems on a vehicle this could be helpful.

Excellent job……. I enjoyed it very much

The best video about CAN bus

I finally get it! Best explanation ever seen. Much Thanks and you deserve all the Subscribe and likes. I now have the tools to check my U0100 trouble code. Cheers

Bro thank you for that. You just simplified something intimidating

Thanks sir for nice information about CAN system

It absolutely blew my mind when I first wired up my digital display in my civic. I have an aftermarket ecu that has a can hi and low output. I connected the 4pin dash connector with the 4pin ecu can connector and wahlah, functioning digital dash. I could not believe it, basically zero setup when using aem infinity and aem cd7 dash. It also supports a wide range of can products, I absolutely love the can network and the digital dash. Little tip, if you have power but no data, and your settings are all correct with terminated resistors, swap your can hi and lo. Mine were swapped on my rywire harness and it took me a minute to figure it out.

well done, very helpful thanks for share it

Finally some good videos on youtube, thanks

Bro just searching through vids online brushing up on different subjects. I appreciate not just the effort, but the concise manner in which you present it. So many videos are hours long and not necessary for the subject matter. Thank you.

Informative and well explained.

Really good training thanks

Very Good and clear explanation!

good job man, thank you so much for your comprehensive and functional training. your accent says that you are Iranian, am I right?😁

Thank you for this insight, looking forward to learning more

Very good marterial, great job! Congrats

Here is always a fan of your videos, thanks

Thanks for sharing, much appreciated

Excellent explanation , thank you very much , watching you from Egypt , it is really fantastic video , waiting for more videos like that, thanks a lot.

Hi..great video...can u help me with an explanation...i want to put a switch between battery and ecu...against thiefs....a hidden switch....do you think is gonna affect the ecu?
I have a Bmw X5 E53 from 2004...
If is ok....can you give me.a hint in identifying the power pin to ecu or another important pin that is gonna prevent engine to start?
Thank you!

A new member is here, just joined the channel membership ‌‌😊 Thanks

Thanks for your effort to share you knowledge. I hope you can make a video on intire for ABS module specially in ford models. Thanks.

Thank you for a good explanation of the different can lines possible.ck,wisc.

Thank you very much it’s really helpful explain

Great vid. Question though, in end of video you showed what a short to ground looks like on the pico waveform. But if you created a short to ground why didnt you blow a fuse?

Great video can i ask what you call those probe converts are for the multi meter?

داداش دستت درد نکنه ویدئوی خوبی بود😁🙌

Thanks alot
You are realy great i enjoy

Good video, thanks!

This video was exactly what I needed to understand the CAN network. Are you going to make any video about other types of CAN too?

Years ago I bought a cheap aftermarket breakout box, and to my surprise the pin numbering was incorrect. I used a sharpie to change the numbering to correspond to the pin-out of the OBDII connector, which allowed me to accurately find pins 6 and 14. Now that you mention it, in retrospect I'll guess they were using the ETM pin numbering you describe in this video. How did it come about to have two completely incompatible numbering systems for the datalink connector?

Im an EC engineer.I found your video information very useful as I have a 18 Accent, installed with a TS7 android player. I was looking for CAN bus to chose while configuring the Android system.I was not sure.

Super video! Thank you!

mersi damet garm agha!

Thanks for all this information! Really well done!

Got you,so helpful big up bro

Thank you ….well explained 🎉

HI there, congratulations this is one of the better CAN bus videos. If I can respectfully suggest something that you could clarify: you explained the gateway module purpose and that terminating resisitors. However, given that both the Nav-AV Modcule and the AC Module (M-Can) are connecteed to C Can, you did not make clear how to determine which module of the two is the Gateway. You simply just stated that it was the AC module. Same for the Smart Key Module and the Instrument Cluster (B-CAN).They are both also both connected to the C-CAN. How do you know that the IC is the Gateway. How do you determine that just be looking at the wiring diagram. Yes I understand you could unplug modules until you see 120ohms on the meter, but that is a very long way around requiring often a lot of work. thanks again.

Very good explanation 👍

High explanations man .. thank you very much

Love your channel

amazing content .

Can u help me car turned off and won’t turn back on. I have no connection to the ecu. I have checked the inside of the ecu and it looks fine. So I was thinking the can bus. Maybe I’m wrong but according to what you say in your video that it’s multifunctional and one won’t stop the other from working? If I go by that it can’t be the can bus system.

Great video brother ❤

Thanks so much for that nice video

I can recognise Farsi from the first sentence - Khaste nabashid my friend ;-)

Thanks Great Video

Great explanation thank you 👍

Great video.👏👏👏

Great video! Question i have is does it cutting and reconecting C can cables(wires) making any disfunction of can bus signals ? For example is the lenght of cables gets changed
Thanks for answer

Thank you very much!

You've really educated me on CAN BUS,thanks so much.

Thanks for your video ❤

I Like this video very much. Thanks for putting it together. 5 *

very good explanation

Hi master u teach amazing thanks for share u information private us!! i have a question cluster peugeot 406 phase 2 year 2002 have terminating Resistor?

Thank you so much 😊
If the resistance is between 37 ohms and 40 ohms in a Nissan Sunny N17 and if you use a buzzer with an ohmmeter between the can high or can low and ground, it will make a buzzer sound, and if you reverse the leads of the ohmmeter, the buzzer will not make a sound.
What is the reason?

Fantastic sir. very exelent

great video

Very good video, I have one question though! To my understanding, there is a voltage on CAN Low (2,5 to 1,5V) and a Voltage on CAN High (2,5 to 3,5V) if not mistaking. And 2 x 120 Ohms resistors at each end of the bus. My question is, will any CAN module, if taken separately, have those voltages at their lines?

Thanks you so much Sir for revealing the mystery 😊

Perfect and well-presented

Thanks for shere ❤

very detail thanks so much for sharing

Thank you lerned a lot

Wow, very nice

Please elaborate on the voltage on CAN HI and CAN LO. What is your reference? Are you measuring the voltage between the two CAN wires or are you measuring from the CAN wires to frame ground? Also, where does the power originate from to provide the voltage changes? Does each module require a 12 volt line and a ground for power?

Thank you for your video...I have a 2014 Dodge Durango...here's the rub...when trying to get a NYS
Inspection sticker and using the state inspection tool the vehicle reves high and all lights come on the dash...BUT when inspection station plugs in their regular scan tool nothing happens scan tool wors fine. This happened at 2 inspection stations... The vehicle runs fine no idiot lights on dash...cold A/C...no hesitation on acceleration...70K on engine...It was a Town vehicle and they had a vehicle gas Id installed so the vehicle could get gas at the Town stations...some sought of radio freqeuncy Id installed... but it was removed Any Help? Thanks Bob

very nice explained sir

I tested according to what I see in your video but I do not see what happens if there is a short to power. When ohm testing 6 to 14 with the key off I get OL. Voltage on pin 6 is 10v and voltage on pin 14 is 8v. The van will not crank or start. The scantool can only communicate with modules on the low speed bus. It cannot communicate with ecm or tcm which are where the resistors are. I would suspect there is a short to power in one of the modules correct?

Very helpful, thanks!

Very nice video thanks you sir ❤❤❤

what a nice persian man😍
