Sierra Bad CAN Bus Signal Causing a No Crank
HTML-код
- Опубликовано: 28 сен 2024
- Today's video is on a 2014 GMC Sierra that had a No Crank concern and a vehicle code scan found that nothing on the High Speed Powertrain CAN Bus was communicating. As usual I'm bringing you all along with me to find and fix this vehicle no parts required.

Another great diag, Jake! Those wires definitely failed the "Keith tug test" haha
Love the CAN case studies! 👍😊
I watch all of your videos regardless of what you're doing. You have an impeccable diagnostic process and are one of the best at explaining your thought process while doing your testing. I strive to incorporate what I learn from you in my troubleshooting process, and I can't thank you enough for all the effort you put into your videos.
Yes! Absolutely keep doing these can-bus network diagnostics videos.
I'm not a tech by any means but I sure have learned a lot from watching your videos while trying to solve my can-bus network issue on my 2019 F150.
Jake, Ivan and South Main Auto are hands down the absolute best when it comes to automotive diagnostics.
dont forget the two keiths
great video , I love watching all your videos , the can bus ones are great... Testing cars ,cooks ya brain so good job your protecting it from the sun, not quite Clint Eastwood style thou , cheers Jake
Keep doing the can bus, you're doing good.
Also the price of the oscilloscope and alternatives Scopes like the Uscope and specialty tools prices.
Im like a moth to a flame with these diag videos 😂
I like these videos a lot I've learned a ton from them. A good visual inspection goes a long way😊
Really like the CAN BUS videos!👍
I watch every video but have learned the most about canbuss communication issues. Watching your videos is like watching your thought process spoken out loud. you're extremely intuitive, and you can see the wheels turning at each step of your process and why you've chosen the particular diagnosis path. your laid-back southern demeanor, and your straightforward integrity is very refreshing. but I've got to admit I'm from the west cost so I adjust the RUclips playback speed much faster so you sound like someone familiar from around here. lol: no disrespect intended.
Lol yeah I talk slow
At least he doesn't show working/not working 6 times (like someone else I (and Jake, does too apparently) follow!
Big fan of all your diag videos. Keep em coming, please.
I really like your network diagnostics videos. They've made me more capable as a technician.
Choose your own adventure/ interactive youtube would be amazing. My jetta has electrical gremlins after a autozone obd scan and I'm sus it did something. Trying to understand can bus wiring so here I am.
You would have to do a livestream, Chad the practical mechanic has done some in the past, where he would ask the viewers where to go next during a diagnosis.
Thank you.
Yes. I do enjoy the CAN bus vids. I have learned alot. Thanks
put a matt finish film not glass screen protector finger prints dont even show up several companies sell them the advantage of film if they don't make one to fit you can order a larger one and use sizzers to trim to fit glare will be gone
Please continue sharing your diagnostic methodology, I benefit from your logical approach. I combine your info with Eric's, Ivan's, and Rainman Ray's to help me deal with a myriad of DIY repair challenges.
You are correct. All the above are excellent technicians.
Jaks ! I like ur hat 😊.
Great job 👍 I am fond of networking, even on personal computers. I really enjoy watching you fix networks. Thanks for your great videos 👍
Very good idea, interactive,nice sombrero I use a similar one and I love it
Your not Old your experiencesed by the way old is gold
Great fix Jakes must inherite your hat taking a fishing trip one of the days 🐟🦈🎣
Maybe you could do a live stream and then have your viewers take you through the process!?!?
Can Bus diag away........great work!
Great video as always
Livestream
Yeah maybe I can get a vehicle that I could schedule a livestream with. That’s a good idea
Hell yeah love them
Great work Jake as usual. Good logical thinking that I regularly apply in my workshop
Great video 👍
Only a LOSER would make fun of your hat, Jake. Skin cancer is no joke (I had a small tumor removed from the edge of my nose). Need to take care of yourself to lead a happy life into your 80s and 90s!
Really good channel. Too few subs... But please, keep feeding us your content!!! Love from California!!!!!!!!!!
👍👍😊😊
The electrical problems in general (including CAN bus) are my favorite videos.
I like all your videos. I enjoy watching the CAN bus diagnostic videos. I retired from being an auto/truck/small engine Electrician, but only saw a little of bus communication problems. And those didn't cause no starts or total shutdowns. So watching You, Ivan, Eric O and Diagnose Dan has added some non book training and understanding of the different CAN systems, plus the tech tips for better/quicker testing. Like that 120 ohm resistor and bingo! The engine starts, gauges works and life is looking much better!
Thank you for this video, and keep 'em coming.
LiveStream but reading comments would be difficult durring diag.-Actual practical hat for hot sunny day.
I love can bus videos. I spent hours sitting in my optima staring at an oscilliscope 😂
Thanks for your experience and job for us like mechanics! Great job!
Give Jose your lawn guy his hat back 😁 .. great video. High sierra drifter maybe
Hi Jake. I love the CAN bus vids and most of what you do. You deserve many more subs as you are a very personable guy and Eric O needs to watch his back, although I love his and Ivans channels also. I would recommend that viewers should hit the Like and Subscribe buttons, as at the moment you have 3070 views, but only 615 likes. Great channel and Good Luck.
I enjoy the can bus videos, not many videos showing the actual work. I have a 14 Sierra 1500 and 11 Denali duramax I’m working on now with zero can bus experience 🤣 both are lightning strike victims
Absolutely just rocked this. I just get so much out of your videos, the diagnostic procedure flow is the best that even I can understand what is taking place. Please keep the videos coming especially can bus as we all know todays modern auto is so driven with computers and various modules. Thank You!!!
Visual inspection. Look where someone else has touched. Twisting wires and throwing on heat shrink is definitely shady practice. A live stream and interactive diag would be interesting. You would probably be looking at, at least, a 4 hour venture and would most certainly need an assistant to read comments so you don’t have to go back and forth too much.
Thanks for sharing your insights & diag procedures, we all do it slightly different
Your's is one of the few that anyone can come to to find accurate diagnostic procedures to unravel CAN system problems.
Fret not.
Change not.
Fill your niche and terninate those connections!😅👍
I am a tech/shop foreman and I enjoy watching all of your videos. Keep them coming. I send some to my techs for learning opportunities. You do a great job in teaching/explaining what is going on and why you are doing each particular test.
Jake great viewing your videos always working from different starting points to get to your final goal that and the way you carry out your diagnosis is truly stimulating and that's what makes them interesting.Cheers
I always watch your videos. Lots of things you have shown on your videos have helped me as a tech. You would make an excellent instructor!!
Great work..learning alot from your methods and videos ..cheers
I only watch You, Eric O and Ivan and I really enjoy them all. If I watch some other channel's video it would be because I'm working on my 2002 Jeep Wrangler and I need specific info on that. I think it's funny that Eric O is now saying "plug up" instead of "plug in" and that's his gesture of respect to you.
Just follow the honda chart,
PUT a BCM
😂😂😂😂
Great video and diagnosis. I enjoy all your videos and just appreciate all the time you put in making them.
Now you just have to bring Meghan along for some friendly banter like Eric and Vanessa on SMA. 😂😂
I like the channel content. I am always learning ideas about my diagnostic plans. I have been working for some dealerships that bought flood vehicles. I am in a world of CAN bus, Power, Ground, and dead modules. Not to mention they like to fire the parts cannon(they are just shooting their shot from the junkyard parts), which leads to immobilizer issues.
I love all of your videos but do like the CAN Bus ones because I'm not as knowledgeable on it as I would like to be.
Jake, I really like what comes out of your brain so my advice to you is to keep the hat and the CAN case studies. I always learn many things while watching your videos and especially like it when you pull out the scope. Thanks for Sharing! 🙃🙂
Great video. Thanks for the splitter amazon link, just ordered one.
i do enjoy can bus fault videos. to be fair i enjoy all the videos makes me think as i follow along and try to see what i would do next or were i would go to check 👍 it high carumber some days i remember why i work in a plant to old for all that rolling about on dead squirrels 🤣🤣🤣 and to old for buffoons twisted together wire no nonsense mind you at least that put heat shrink on it 🤣🤣🤣🤣 that did make me chuckle .
All of your electrical diagnostic videos are interesting just keep doing what you are doing
Yes I like these video. I'm a DYIer that enjoy working on vehicles. I understand electricity very well. %0 years working in communication, measurement and electronics. Everyone of your videos has either taught me something new. Even though i have seen some of these problems before, repeats help remind me how to troubleshoot and dissect the cause.
Jake, you have the best mobile diagnostic channel on you tube. The video's are spot on and easy to follow and enjoyable. You will get to 500k subscribers just give it a little time. Great video!
That wiring repair from the previous "tech" reminds me of a young guy who worked in our shop. GM had a recall on the 08-13 r/v body suv to cut out the airbag connectors under the front seats and hard wire the circuits. This guy was doing them in half the time anyone else was. Eventually the first one came back and was assigned to me. Circuits were twisted together and shrink wrapped. After the 10th one came back he no longer had a job. It was so bad across all dealerships they had to issue a special policy extended warranty on this issue. Id love to see a video on an intermittent communication issue thats very hard to duplicate.
Think about in the future when you can just plug in your PC to the DLC and make a simple AI prompt, telling it to recreate a copy of the best scantool available for the car you're working on: and it just builds out the software right in front of you in a few seconds or minutes. This is the level of capability that AI is supposed to come to within the next 20 years. It already can write code pretty well
Keep up the good work. I like it when a dirty car is being diagnosed. Too many videos I've watched lately have been with spotless cars with problems. Not realistic. You are genuine.
Any diag videos are good,can diag love them,the thing for me is that we get to learn all together,thanks for sharing your diags,
I've seen interactive videos like that in RUclips. THinking back: I think they may have just been short videos, and when you do the "interactive choice" - it would just link you to the next video. but those are a lot harder to make than you think-- because you have to make so many little videos, including things that are unnecessary. It never really caught on, because it's too much work and not much pay off.
Jake I appreciate every troubleshooting video you put out especially now that the CAN BUSS is the at the heart of most problems and a lot of times it comes down to shoddy wire repairs. Oh nice hat but I’m sure it gets in the way of under dash troubleshooting . Lol. 👎 Artie. I just ordered the splitter from your store always like to support guys 👍
25:18 To proving that is equal time like repair it, so, better to be repaired at once... except, if customers wants opposing.
i have learned so much from you sad thing is i have never had a can problem come in my shop i do a lot of drain testing. i watch you and ivan and south main and several others. that being said i now have something to fall back on when a can problem comes in my shop and videos to refer to so please keep sharing all the content you have tim,e to produce no matter what it is helps me and others more than you will ever know
Anything network or electronics is great. With so many supply chain and knockoff issues, there are tons of vehicles being sold or scrapped unnecessarily. Opening up modules and programming is always exciting to see on this channel 👍
Eric O has great Video's, I have to say You also have great Video's . I can't get enough of you guys. I learn things here that I couldn't anywhere else. Keep up the great Video's please.
CAN-Bus and your thought process is why I'm here. Thank you for putting this style of video together.
Yes, it's interesting and scary in equal measure, but I have to deal with it and with your help I'm dealing with it, and thanks again for sharing
one of the best channels buddy thanks for taking the effort to share i learnt a lot watching your videos keep doing can bus videos you help a lot people trying to learn this stuff 👍👍👍
Another great one! I do like the CAN bus videos, they have helped me more than a few times track down an odd problem by eliminating or confirming a network issue.
Thanks for posting. You have to love cleaning up someone else’s mess. I always soldered wires and heat shrink.
I like watching anything you diag.. because it's all something that I could run into-- so I like to see it all and learn it all. I especially like it when you break open modules and fix internal boards or program them, etc.. That's the one thing that is still more rare in the diag video world. Can bus is great too though
Excellent work as usual! I imagine the network would look much cleaner on the scope after repairing that harness.
do it live and the ones can post comment and you can answer would be a little slow but i have seen Ales the car Dr. do a question and answer live feed
Diagnosis is my biggest weak spot, I watch your videos so I can improve.
Seam rippers are great for dealing with electrical tape in seconds, and pretty safe for the wires.
I watch all of your videos and I really enjoy the diagnostics, especially on the network
I really like to watch the way you trouble shoot can buss issues. I have no or very little knowledge of the process .Thank you ck,wisc.
Interesting idea about the interactive video. Only thing I could think of would be if you had say 3 different directions you could go, you could film all three diagnostic paths and splice them into one video and when you get to a turning point, you can give a time stamp to jump to for each option.
This was a fun diag. That double dlc connector you have is sweet i love that trick you used with the resistor. I would have never thought of that. Great idea to get something into the building instead of pushing
I like the can videos here because you are thorouh and probably the easiest guy to followon these issues. I mean I'll watch whatever your diagnosing, but its nice to have a chanell that is heavily focused on the scope use and such so we can always keep our skills sharp.
Love the can bus diagnostic videos. Unfortunately I don’t get very many to work on
I use bare crimp sleeves for wiring repairs, then solder the sleeve to the wire. The sleeve gives a mechanical connection that will hold the wires in place and eliminates the sharp wire strand ends that try to poke through the heat shrink. It’s faster and less frustrating in cramped places and allows all wires to be spliced then soldered in a batch operation.
Like the can bus videos. Most of your videos are pretty interesting.
Speaking of Eric O did you see the one the other day some cut the engine light wire and shrink wrapped it apart to keep the light out I really like your channel you are one of the few that do mostly can bus
Wow, what a quick diagnosis, well done and I learned something else, thanks
I never comment any video,this video is so helpful and i really apreciate it ,also i would like to see the waveforms in pin n6 and 14
Viewers have trust issues like they do with Eric @ SMA , you got to show everything . I enjoy chasing can problems even if its with my little pocket scope , keep it coming great job 😃😃
Jake, thank you for another great video . Your videos and teaching methods are a very valuable resource to those who have a desire to learn . 🇦🇺
Don't stop doing what you do. With every video I learn something new.
Yes keep up the can bus.
As a Toyota tech we don't get many can problems so need your videos
Me too I enjoy can bus videos it help alot to open our mind to do a diagnostic on cars specifically on the new cars thanks for sharing your knowledge
In Texas a lot of people wear those straw hats. Definitely protect you from the Sun
i definitely like it, i enjoy doing diagnostics and learning...keep at it.
Honest that idea is amazing! Interactive learning...
Really love this kind of videos. Love your channel….
I would pick one problem that seamed accessible and track it
I really enjoy your can bus diagnostics 👍👍👍
