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 [e-mail] what's app no 00923009661809 again THANKS to you sir

[@mmichaeldonavon]

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.

[@Diagnosedan]

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👍💪

[@Stambo59]

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.

[@Greg-lo1tl]

Have you since been able to diagnose any can-bus issues?

[@robinsonsauto]

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.

[@robinsonsauto]

I hope you got lucky again hahaha that was great 😂😂👍

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?

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..........

[@PineHollowAutoDiagnostics]

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?

[@Diagnosedan]

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!😁

[@PineHollowAutoDiagnostics]

You should show the coding part too ;))

[@Diagnosedan]

Pine Hollow Auto Diagnostics, I'll do a separate video on programming and coding, when a nice case study comes along😉

[@ggstephens50]

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

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

[@CubasAutomotive]

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! 👍

[@Diagnosedan]

Thanks Cuba for the great comment, it's an honor. I use Hella Gutman wiring diagrams.

[@randyeller8139]

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!

[@frugalprepper]

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.

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!

[@Diagnosedan]

stuzman, i would have plugged it back. The chance that you have 2 modules failing at the same time is not likely.

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]

A RAHMAN, Yes with the bad module removed from the network you should be able to communicate again!😉

[@Abdul_rehm7n]

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]

A RAHMAN, Scope the can-lines And check what's going on. Also check the power and grounds on the dlc

[@Abdul_rehm7n]

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

[@Diagnosedan]

A RAHMAN, Great work!👍👏💪

[@The-truth-is-valuable.]

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.

[@sinegra30]

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.
