Thank you for posting this fantastic video, i followed it all the way through, as i have a very problematic car here to solve, so now i will get a 'Can' (of cola) and take the 'Bus' HOME 🙂👍
Hmmm, decent test plan, but it is 2024; invest in some tools and equipment, e.g., Breakout Test Lead, OBDII Breakout Box, Oscilloscope… I have seen too many misdiagnoses when individuals use the basic test leads that come with the Multimeters. I had a GM Tech trying to convince me that a VVT Solenoid was bad based on the resistance he performed. The test lead probes were unstable in the Connector Cavity when demonstrating the resistance test. The readings fluctuated, so he was under the impression the solenoid was bad until I used some of my breakout test leads and scope in resistance mode, demonstrated the resistance was within the desired range, and corrected the engine oil level, which resolved the concern.
Hi my friend. Normally ECM refers to Engine Control Module only, and PCM refers to ECM+TCM. So wiring diagram technically covers both cars with automatic transmission (that we must look at PCM on the diagram) and those cars with manual transmission (that we must look at ECM on diagram).
Yes, on many cases we have to use the scope to diagnose the CAN-BUS as resistance and voltage inspection might not be helpful. You can watch the following videos in our channel that I used the scope for CAN-BUS diagnostic: ruclips.net/video/fVy_EXkMKMg/видео.htmlsi=Kr8HT9-nc5RYE4ak ruclips.net/video/GDsGjhNG_ys/видео.htmlsi=dcumc8CY5dPMYCRH
@@AutomotiveDiagnosis thanks for this. What I am wondering: in both cases (using a DVOM or a scope), would the outcome be the same: locate a failing module or issue in wiring and then either replace/rebuild the module or fix the wiring. If that is the case, why bother with a scope, if a DVOM will be able to locate a failing module or wiring issue. I am not trying to be contradictory, just trying to learn. Thanks again for the videos.
Hi my friend. If CAN-L is short to ground, diagnostic procedure is the same, you will get the low resistance when you check the resistance between CAN-L and body ground, and when you check the resistance between CAN-H and body ground you will get 60 ohms (if all control units are connected.)
For this one I used KIA GDS which is the OEM scan tool which comes with all diagrams, but we have some wiring diagrams in PDF and will provide them to everyone very soon.
Hi there, luckily there was only a minor issue on the wiring insulation not on the wire itself, so very easy to fix. But in case of having any damage on the wiring on the CAN-Bus, I never do soldering, as I do on the normal wiring, I rather to replace the wire between two ends.
Same way of troubleshooting, the only difference is to check the voltage on the CAN bus and go step by step. You can find our full online course about "CAN-BUS diagnosis on the link below: www.udemy.com/course/automotive-can-bus-network-intro-application-diagnosis/?referralCode=C0C59CCB3595CB9C0C13

I love every single diagnostic video in this channel, thanks
Thanks for watching the videos and supporting us.
This video is absolutely informative and helpful
Glad you think so!
Thanks for all info I’ll joint can bus course very soon 👍👍👍👍
Hi my friend, thanks for your support

This is impressive. Today i changed the gateway module of vw tiguan tsi which is not communicate with all the modules except instrument cluster.
Thanks a lot for sharing your experience.
Thanks for the time to show us the diagnostic CAN BUS
Thanks for watching
@@AutomotiveDiagnosis CAN network is my lovely diagnostic it gives a challenge to diag. I hope I can see more videos like this
Terrific video and explanation . Thank you for sharing 👍
Glad you liked it
Good video! Question how do you know which correct is ip21 does the diagram tells where are they located? Example under the dashboard)?
Hi my friend. All components and connectors locations are in the wiring diagrams.
Good information ❤❤❤
I’m glad you liked it

Thanks my friend.
Absolutely brilliant

Thank you so much for this video

Great video thanks for sharing

Another excellent video.
At 2:27 why does the diagram show PCM and ECM usually they are the same thing.
Hi my friend. Normally ECM refers to Engine Control Module only, and PCM refers to ECM+TCM. So wiring diagram technically covers both cars with automatic transmission (that we must look at PCM on the diagram) and those cars with manual transmission (that we must look at ECM on diagram).
@@AutomotiveDiagnosis Thank you for the reply
Thanks for the video. Good diagnostics. Do you ever use a scope for CAN-BUS diagnostics?
Yes, on many cases we have to use the scope to diagnose the CAN-BUS as resistance and voltage inspection might not be helpful.

If CAN-L was shorted to ground how did the resistance measurement show it was ok ?
Hi my friend. If CAN-L is short to ground, diagnostic procedure is the same, you will get the low resistance when you check the resistance between CAN-L and body ground, and when you check the resistance between CAN-H and body ground you will get 60 ohms (if all control units are connected.)

What program do you use for electrical diagrams?
For this one I used KIA GDS which is the OEM scan tool which comes with all diagrams, but we have some wiring diagrams in PDF and will provide them to everyone very soon.
Super thx.
Good information,, can you do a pull down and pull up circuit
Sure my friend
@AutomotiveDiagnosis i wish you could it
So umm... How did you repair that wire? That would have been interesting to see being it's a data wire

Is it possible to check resistance ON CANBUS when the battery on
HI my friend. For checking the CAN-BUS resistance, ignition switch must be off.
@@AutomotiveDiagnosis Thank you very much, I appreciate your quick response. I did not hear you mentioning it or perhaps l missed it🤔.
not recommended...
how about short to power,

What if it isn’t 60 ohms but 80 ohms
There could be some connector problem, try removing one of terminating resistors and see what will happen to the resistance measurement
