Can-bus Trouble

In this video we diagnose a Bmw 5 series with a transmission Failsafe program and a non working speedometer.
In this video i explain the basics of Can-bus.
And in the end Diagnosedan Fixed it again!
Hope you enjoy the Video!

[@ScannerDanner]

Nice video brother! Thanks for the lesson

[@Diagnosedan]

ScannerDanner, Thanks Paul Not that you need it😉 I appreciate your comment buddy!👍

[@ScannerDanner]

I really liked the "echo" analogy. It helped me. Seriously

[@c14back2nitrogen9]

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?

[@mowerdog]

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..........

[@Diagnosedan]

Ha ha, thanks for the nice comment, things are changing fast . And alot of new things comming in the next years.

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.

[@lameckarika1949]

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?

[@BuggysTowJam]

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.

[@shameelali2549]

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

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...

[@Diagnosedan]

Thanks Jeff, good luck😊

[@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.

[@mostlymoparih5682]

Can e bus trouble, you very funny Dr Jones. You reminded me of a story my brother told me. Years ago he worked as a mechanic for a public works department. He worked on everything from police cars to dump trucks. One day he had a police car that was not getting power to the trunk light. He started tracing down the problem and had to remove the back seat. Well a few nights earlier the police had arrested a guy they thought was selling pot. They transported the guy to the station and then noticed the trunk lights not working. The guy had a pound of pot in his pants and on his way to the station he pulled it out and shoved it in between the top and bottom parts of the seat and pulled a connection apart. Problem solved but they couldn't connect the pot to the guy they arrested. Good video.

[@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.

GRUSS Newton, Yes i'll do more video's on networks, can-bus e.o. We'll dive a little bit deeper every time. The only problem is i never know when a good case study comes along. So i can't tell you when. In the meantime i'll do other intresting video's!😁

[@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]

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

[@gerardasnausutis3166]

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 :)

[@Diagnosedan]

Gerardas Nausutis, I tried to concentrate on the Can-bus in this Video! There will be a separate video on programming and coding. But indeed the module needs to be coded!👍

[@OrangeDurito]

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!

[@fuzzs8970]

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.

[@stuzman52]

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.

[@gharbimecatronicien576]

One of the best instructional videos i have viewed on KZbin, 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
