I really appreciate you taking the time to make these videos and sharing your knowledge with us your awesome at what you do and please keep making and sharing your work
Another very informative post. Yes drawing it out helped me understand it better but as I have said I'm a shade tree since the early 70ies. But what is great with you and Ivan is if I come across something I know one of you will have a video that will help me. And I do enjoy all of them so please keep them coming. Thank you.
I don't find the right words to describe this video. But I'm telling you, I keep watching your videos just like a younger student who's eagerly wishing to learn and follow your steps, step by step.
Great thought process! Simple repair, but very informative video, with good explanation on the effect of an interruption on the CAN bus, with the waveforms corresponding to where you scope. By coincidence, Ivan from PHAD just led a crusade to resurrect a Cobalt with most modules damaged by careless welding - three epic videos :-)
Awsom video, excellent diagram. One more point. A closed loop network with terminating load resistors at both ends offers a self-healing environment. The two 120 ohm load resistors if they see each other result in a 60 ohm total load for all high impedance devices on the network. The network can communicate between all modules with a termination load range between 60 and 120 ohms.
DUDE YOU ARE WAY OUT THERE , THE SPEED YOU RUN THROUGH THESE GM CAN DIAGNOSTICS TO ME ARE AMAZING . I HAVE ONE 5 VOLT REFERENCE SENSOR SIGNAL KICKING MAY ASS FOREVER AND YOU JUST DID THE DIAGNOSE AND REPAIR IN AN HEARTBEAT SO I MUST BE IN THE WRONG PROFESSION . THANKS SO MUCH FOR YOUR TIME 🙏🙏🙏👍👍👍
Nice video and thanks for taking the time to explain the network issues. Seems like when you checked pin fitment with the AES adapters you might have cleaned them at the same time. Ivan at PHAD just finished up a three part case study on a Cobalt with a whole bunch of fried modules.
@@autodiagyt ha I bet they all look brand new underneath in your area 😉 Awesome explanation of the CAN signals with the drawing too, definitely learned something new! 👍
Jake, thanks for explaining this a bit more. I think I'm going to have to watch this one a time or two more as it seems I only have a slow speed bus in my brain. 🤔🙂 Intensely interesting though. Thanks for Sharing!
Hi.very well explained especially with the help of the diagrams and well executed let's hope its fixed if not you know to return to. After all it is a 2006.Cheers.
Deoxit has worked on for me but stabilant 22 is the way to go on sketchy terminals. Use it on a lot of airbag connections and it’s never failed me. It’s expensive for a 2 oz bottle but it lasts forever as it only takes a drop
I am happy to see that you re-flowed the solder joints - I have a theory that in a vibrational environments, with a loose connector, the metal (copper?) work-hardens. So to my mind, re-flowing the solder joints has the added benefit of annealing the metal somewhat. If true, then doing so "unloaded" would also be important... Just a theory...
I've been reading about gateway modules, that change the game as far as exploring the CanBus system. Is that the way of the future, we won't be able to access CanBus though the DLC?
I'm not sure if I agree with your drawn analogy of explaining how the circuit was still able to function with a severed Can Lo wire. Don't understand how the Can Hi and Can Lo both could travel across that 120 Ohm resistor in two different directions. Seems to me...that a break in either circuit would collapse the inductive section of the wire somewhere in the line and would result in a just 'Can Hi' signal!
Hey, I see you ride bikes, looks like Mountain Bike riding. I ride a rode bike but when I was a little younger I did some Mountain bike riding, in fact, I purchased one of the first full carbon hardtail bike off the internet. I still have it. I have an older LOOK 695 road bike and still ride 40 to 50 miles a week. Really appreciate the videos and while watching see you seem to struggle sometimes which is the case for a real video and not a planned video. Keep doing the videos, please. I could use your expertise on an issue with my 2009 Pontiac g8gt. I rebuilt the engine with the help of RUclips. Always hated working on cars. Everything finally got done but now I have an ESF and stabilitrack lights come on but only when I slow down or stop at the light. It has a bad effect on my RPM and the engine wants to shut down if I don't feather it with the brake peddle. I have a few voltages that should be on the BCM but are not. You could probably figure it out. The schematic that I purchased does not agree with my Manual on the wire numbers on the BCM. Just purchased a used EBCM so I need your advice as to what type of Diagnostic Scanner would help me look at the steering wheel angle sensor and yaw control sensor and be able to reprogram the EBCM to my VIN number. Wish I could get you to look at it but I really want to figure it out myself. I need to stay under 1000.00 dollars if possible. Any help would be appreciated.
Hello I’ve worked on and Train on Device Networks on Machines. On Industrial Device Network Modules the internal Resistance is 36k ohms to 39k ohms this is the industry standard for Device Network modules. This is checking across CAN_H & CAN_L with you Ohm meter.They also have a Node Address assigned to each module. They also have a Master Scanner unit. Also have you ever measured your CAN_H to Common or 0volt and CAN_L to Common or 0volt. In and industrial situations the network power is 24 volts DC. You can High and Low voltage should added together around 5.6 volts Dc. Enjoy the videos up here in North Alabama.
Automotive CAN uses a 2.5 volt bias and pulls up on can high to about 3.5 volts and down on can low to about 1.5 volts. The reason industrial can bus uses higher voltage is just due to the length of cable runs and the higher voltage can give some better noise rejection.
These have a ground that goes bad right under the oil filter. They loose contact between wire and terminal. I dunno if thats your issue Im watching the video now.
@@autodiagyt 😁👍🏼 -Electric NooB here. Been watching your videos for a while, wondering if this is the right place to ask for guidance on a Short to GRND from license plate to battery? 🙃
I would have run a continuity test on BOTH wire from the terminal connection to the PS module back to the DLC. I sure wouldn't try to solder those PS mod terminals in that position: but would have taken it out, and then bench solder it.
how much would you charge a customer forr such service? Also when you get a system going wonky like that ask if the vehecle has gotten wet recently. i have an f150 when it rained water would some how creep thru the inside driver pillar and wet the gem module down in the kick panel.

Ivan at PHAD just finished up a three part case study on a Cobalt with a whole bunch of fried modules.
And Ivan just posted Part IV this morning! It’s quite the saga…
Thank you for the really good and clear explanation of the CAN lines. 👍
Oh no not another Cobalt 😅
@@autodiagyt ha I bet they all look brand new underneath in your area 😉 Awesome explanation of the CAN signals with the drawing too, definitely learned something new! 👍
Excellent.. I enjoy your walking us through this and explaining. makes sense!
Great video. That drawing was super helpful.
nice explanation on the can hi can low and identifying which has a break
Dude you get the coolest case studies.

Thank you very much for the information and explanation
Great learning video, as allways!
Thanks for the explanation at the end.
Great vid, very informative
Great diag and very good and detailed information 👌. Cheers
Great video and very informative. Thanks again.!!
Thanks for sharing your knowledge sir
I made a small 120 ohm box with 2 two 4mm to adapt aswave test leads to it for different connections to bump in on line for testing and verifying.
Great explanation and diagram

Time will tell Good job.
Amazing stuff!
Solid diagnosis! Thanks
Good job 👍
I have seen it for the ground strap on that TCM and it fixed it that's a good one too
awesome diag
I feel like I just watched Ivan do something very similar
And on the same car too. But in his case, all the modules were basically fried.
great diag video
Awesome 👍
This is great info thanks for sharing
Best video it is great thanks 😊

Hi Really appreciate the thorough explanation and one of the best footage on the game😁 Curious- what camera setup do you use? Much thanks
@@autodiagyt 😁👍🏼 -Electric NooB here. Been watching your videos for a while, wondering if this is the right place to ask for guidance on a Short to GRND from license plate to battery? 🙃
Was the tape on the wires coming out of that connector factory? I couldn't tell on the video.
I would have run a continuity test on BOTH wire from the terminal connection to the PS module back to the DLC.
I sure wouldn't try to solder those PS mod terminals in that position: but would have taken it out, and then bench solder it.

Fraying is how you spell it? What is the name of that spray? Is it the same as stabilant 22?
No it's not the same. Deoxit is more of a cleaner and stabilant 22 is more of a bonding agent, like locktite for electrical connections.
did the ps module suffer a cold solder joint
Still want to know where you get those test leads
thanks million@@autodiagyt
Grasias
Have you ever used a escope?
why are the resistors needed
oh spoke too soon. the pins looked, from the distance of the camera to be fine.
Hi.....where are you located?
