Sierra Bad CAN Bus Signal Causing a No Crank

[@PineHollowAutoDiagnostics]

Another great diag, Jake! Those wires definitely failed the "Keith tug test" haha Love the CAN case studies! 👍😊

[@ThunderbirdRocket]

👍🏼

[@JohnDoesGarage]

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.

[@ThunderbirdRocket]

Agreed

[@karlkoenigstein4138]

Very much enjoy CAN bus diagnostics. I’m very inexperienced in them so it’s a big help to me.

[@stevejohnson345]

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.

I love the can bus diagnostics

[@bobcombs7138]

We will take anything you can give us Jake! Excellent once again 👍

[@ThunderbirdRocket]

Yes 👍🏼 indeed / agreed.

[@JustMe-Dude]

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 KZbin playback speed much faster so you sound like someone familiar from around here. lol: no disrespect intended.

[@autodiagyt]

Lol yeah I talk slow

[@markashburn3003]

At least he doesn't show working/not working 6 times (like someone else I (and Jake, does too apparently) follow!

[@RipCityBassWorks]

The electrical problems in general (including CAN bus) are my favorite videos.

[@ThunderbirdRocket]

Yeah that’s what I am hoping for as well.

[@tracycolorado]

Bring it on . This is all new to me 😊

[@CraneofBoulogne]

Old retired truck mechanic here, I sure enjoy watching and learning from you! Kind of you to share your day to day experiences in vivid detail. Thank you.

[@MILKMAATTERS]

Im like a moth to a flame with these diag videos 😂

[@GregoryBirulkin]

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.

[@RollTyde65]

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.

[@ThunderbirdRocket]

Excellent instructors !

[@stevenakn1]

I like these videos a lot I've learned a ton from them. A good visual inspection goes a long way😊

[@survivingga]

I really like your network diagnostics videos. They've made me more capable as a technician.

[@neverstoplearning382]

Whatever you do is pure gold. Thanks a lot for that Jake.

[@EKHondaMotive]

Your's is one of the few channels 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!😅👍

[@mike-s8n8y]

I am from the UK , here you would think diagnostics an especially system comms was some kind of voodoo or outer space technology , the sharing of info is poor so even people in the trade are in the dark never mind Diyer;s, but that sums up the UK , keep doing these vid's they are very much appreciated by people who care to learn 👍👍👍

[@autodiagyt]

You should check out DiagnoseDan he is somewhere in Europe.

[@mike-s8n8y]

@@autodiagyt thanks , yes he is good and shows european vehicles but i like your approach and the way you talk and explain things slowly that helps no end when trying to learn , thanks for replying.

[@ThunderbirdRocket]

@@mike-s8n8y Agreed ! Jake is a very thorough coach / videographer .

[@robertmobileman8304]

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

[@bobdoingbobthings]

Diagnosis is my biggest weak spot, I watch your videos so I can improve.

[@thk7513]

Don't stop doing what you do. With every video I learn something new.

[@cpcoark]

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.

[@raymondmetcalf9110]

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

[@waqasazmat81]

Every single video of yours is full of gold. So please keep on coming, thanks Jake!

[@douganderson7251]

Ivan is sporting a hat now too.

[@RJJ6129]

Really like the CAN BUS videos!👍

[@ThunderbirdRocket]

I like 👍🏼 the network diagnostic lessons . No question about it - your coaching cues (descriptors & emphasis & slogans ) and your leadership (relating the presentation back to us your followers) and the way you inspire us students is world class . Things such as the videography and the consistency of walking us through your tools, stating the official names of things, how to do hook ups, explaining how to make sense of wiring diagrams, what the random strange noise was under the vehicle, why that noise might have stopped, historical known problems with certain vehicles etc … are the distinguishing factors turning ANY lesson you might provide into a grand slam home run !

[@dnorman2134]

CAN-Bus and your thought process is why I'm here. Thank you for putting this style of video together.

[@alank616]

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 . 🇦🇺

[@ThunderbirdRocket]

The best !

[@mrblonde2013]

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.

[@jumpinjimmy69]

Maybe you could do a live stream and then have your viewers take you through the process!?!?

[@griffith04]

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.

[@tomhague1162]

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.

[@kellygibson7299]

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 👍

[@ashercohen4739]

Wow, what a quick diagnosis, well done and I learned something else, thanks

[@3TsMOBILEAUTOMOTIVEREPAIR]

I like all the videos you post. It helps a lot. I’ve never been taught the scope or can bus diag in my 20 years. I post constantly even telling people I don’t know what I’m doing with but I’m learning everyday when I come across these issues. Trying to encourage the younger or even older guys to just go try it and learn we can’t get as good as you or scanner danner or Eric O if we don’t try. My hardest part is the people who comment and try to tear me down. I have a hard time not commenting back to defend my channel and my goal. Thanks for what you do it’s very encouraging

[@autodiagyt]

Just keep learning and trying! It definitely takes practice and then one day it will just click. Then you’ll get a car a year later that really just humbles you lol.

[@3TsMOBILEAUTOMOTIVEREPAIR]

@@autodiagyt thanks for the encouragement!! keep the videos coming

[@mikechiodetti4482]

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.

[@sheerwillsurvival2064]

Give Jose your lawn guy his hat back 😁 .. great video. High sierra drifter maybe

[@firstlast---]

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

[@GregoryJones-px1hr]

The longer the video the more I seem to learn! Thanks Jake!!

[@tyepickett]

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.

[@calholli]

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

[@basilrichardson4069]

Great fix Jakes must inherite your hat taking a fishing trip one of the days 🐟🦈🎣

[@JoseSilveira-newhandleforYT]

Great diagnostic, Jake! Diagnosing network faults is always very interesting, more so when it's a challenging case. It would be very hard to have an interactive video with viewers - a live would allow it, but the thing would take hours of your time, and the benefits would be unpredictable. In this particular fault, I can't imagine why someone would go through the trouble of twist splicing all wires (replacing the connector, perhaps), use heatshrink and not solder or crimp each individual wire! It would only take a few more minutes to do a proper job.

[@autodiagyt]

Again. They was close to a successful repair lol. A little solder and adhesive lined heat shrink would have saved this customer a tow bill and my repair fee.

[@JoseSilveira-newhandleforYT]

@@autodiagyt Absolutely! It doesn't make any sense, from my point of view, at least.

[@seanmiller678]

Honest that idea is amazing! Interactive learning...

[@daviddasilva4897]

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,

[@jeffco908]

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.

[@MiracleMAX]

Great work Jake as usual. Good logical thinking that I regularly apply in my workshop

[@advancedleveldiagnostics]

Great job as always! Thanks for sharing!

[@curtisroberts9137]

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.

[@rogerbain1029]

This is my first can bus video, but I love this video, I love this real world issue, keeping it real , keep doing these type of video on can bus stuff 👍 👌

[@hikerJohn]

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.

Programming is really so boring lol.

[@toddautoandkids5037]

@autodiagyt not when you are trying to learn the different programming gm is easy yes but to learn others when just starting can be little scary

[@autodiagyt]

@@toddautoandkids5037 the hardest part of each one is getting the account setup and software installed. Once you have that the other 95% is reading service information.

[@H750S]

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.

[@craiggoodwin9704]

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! 🙃🙂

I commend your hat choice. It has the best functionality/price rate you can get. I also wear such hat when working outside. It offers good protection all around, unlike a cap, so your neck is also protected. It allows for ventilation. It's cheap. It's perfect.

[@LincolnAutoDiagnostics]

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.

[@stevepark5504]

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.

[@ashercohen4739]

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
