Simply Brilliant, Keith. Your thought process and testing is so dialed in! It's like the 6th sense haha

Accomplished New level Auto Video great tutorial👌Thank you very much take care and have a great Evening Accomplished New level Auto From Nick Ayivor from London England UK 🇬🇧

I mainly do big trucks and industrial engines . These simple. Videos have provided a foundation for me that goes beyond the trouble tree schematics that take you no were techs in the big stuff struggle with J1939 issues because they dont understand the basics steps of diagnosing that 2.5 volt and scoping the signal they just want to ohm the pins and move on Point being thank you for your very amazing videos

Keith, seriously. I'm mind blown how you diagnose that quickly lol. I tried to follow how your thought processes go. I'm not a wizard not even close at all. But this is great lesson for me to learn something so cool how to do. Great class :) you da man! Many many thumbs up

Sounds like you've catched a cold🤧! But it's not slowing you down💪

You're an automotive wizard! You've proven yet again that that a scope is a necessity in this field. Nice work, I always learn something from your videos.

The Master Diagnostician!!! Always at his best!! Nice one Keith!!

Nissan Frontier: the very best of 1990s automotive technology you can still buy in 2019. Thanks and Merry Christmas, Keith--feel better!

Another great video, keith! I always love your thought process!

I ALWAYS look forward to your videos. Thank you for sharing. You make this look so easy.

Thanks Keith! You can't help but learn here! Merry Christmas and all good wishes to everyone! TakeCare, Bill

Nice work, making it look simple.

Thank you Keith. Hope you get well soon. I appreciate your videos brother. Have a blessed and safe week. Merry Christmas to you and your family.

Keith, Excellent diagnosis, thought process, and video - thank you! Merry Christmas God bless Paul (in MA)

I bow to your knowledge and experience. TY I have learned alot from you. Merry Christmas to you and yours.

Darn it Keith.. You make this look so easy. Gonna have to follow along on the facebook page😁😁😁😁

Another great CAN line video, appreciate it....and Merry Christmas Keith

Awesome man you just answered a few questions I had about the setting Varus scope...and nicely done btw.

Happy Holidays M. Keith and Family from up north waaaaayyyyy up !

Another great one Keith! Thanks for sharing and bringing us along. Merry Christmas to you and yours as well.

Glad to see the intro back up to specification!

Man I hope your feeling better by now. It must be a good feeling when the car starts. Nice find.

Merry Christmas you also! As always looking forward to more of your videos Keith.

thanks Keith. Have a great Holliday season.

Love the way you think and your approach at finding the problem, good stuff man..Liked and Subbed..

Yes He makes it look EASY , Still learning on my end THANKS !

Thanks Keith. Merry Christmas to you and the family.

Hey Keith, nice to see you again. Thanks for sharing. Happy holidays to you and the family. Still looking for those stickers.

What causes the elevated voltage? I'd imagine it has to be a bad, or lack of a ground internal to the ABS unit? Amazing how one unit can bring down the whole works, and leave you walking!! Welcome to the 21st Century ... 😂 You and the family have a very Merry Christmas, and a Happy, Prosperous New Year. God bless you, brother. Thanks for all you do!

Thanks Keith. Feel better. Merry Christmas to you Rocco,wife and family. Enjoy👍👍❤

Wishing a very Merry Christmas to you and your family. Thanks for the video.

Great job again like always

Awesome one Keith!! Merry Christmas to you and yours as well!!

I have an 06 Frontier V6. I'm keeping this video for reference. Mine has ABS, but no Traction Control. It does have 4WD with a 6 Speed Man Trans and a 4.0 L engine. Cold EZE works for me. Merry Christmas

hope you feel better, good stuff as always

I’m always amazed how quickly you diag a vehicle.

Awesome diag Keith!

Thanks Keith. Merry Christmas.

Nice Keith. How nice of them to put that abs module so we can get to it.

Thanks Keith. Merry Christmas

Nice work! Merry Christmas to you as well!

Merry Christmas to u Keith another great video

Keith always make diag look easy

Merry Xmas Keith nice diag good thought process

Thank you!! Great video.

You made it look easy Keith! Not to much snot dripped

Bro. loving it.

Super fast diagnosis, feel better Keith!

Well done. Get well soon.

great job Keith thanks

Awesome content...thanks for sharing

Nice video Keith !

Merry Christmas to you and your family Kieth

Thanks for the video.

Oh I forgot Hope all is well and Covid stays away from you and all others in the world. I've been lucky so far.

well done sir , thanks for sharing

First Bam! Ok ok I’m not first. This was a walk in the park for the magical mystifying Keith D 😂😂 excellent video my friend. Merry Xmas to you and yours and the rest of the KZfaq family.

Good job 👍 thank you

BEST ❤

Excellent video

Very Nice!

Hello Hello Hello. Hope you feel better soon.

Awesome 🏆

In the IT network world this type of behavior would be considered a denial of service attack when bad packets flood the network and no one else can talk. I can just see a firewall/gateway on the CAN bus in the future where all modules go through the gateway and the gateway stops the packets from a bad module as well as identifies and turns off that module. I think some systems like on Hondas they do isolate certain modules and the DLC behind a gateway but more for prioritization so lower level functions don't interfere with the more critical module functions.

Merry Christmas

Captain Kirk called and admires your Spock like diagnostics..he also said"this is not the Final Frontier"😎 nice vid👍

Great video Keith...I tried pausing the video to pull up the Computer Data network diagram to see where you were going with it and I found where all the K-lines come to a splice point in which they all converge. What I'm wondering is why the SRS and ABS were the only two not communicating to the DLC? Since your DLC connection point is at that splice point as well? It seems odd that those two failed to talk; yet all others were still able to push messages through it? Is this due to them having HS CAN lines? Weird how that happens, but in either case, I kind of figured some type of unplug it test was coming up. Great time following along as always. Get some rest man!

How are things going up there. God Bless you and your family

Wow you just ran right threw it like a breeze. 👍🏾

First with the thumbs up 👍👍👍👍💣💣💣

Nice find Keith. I'm going have to go to the diagram and follow along on this one 😉

Nice 👍👍

Nice work Keith. Love can issues

The ABS Module is just speaking in tongues. I heard that's common on the Island after a night of heavy drinking. Jus' let him sleep it off. He'll be fine after some comfort food and a coffee.

Merry Christmas to all.

second BANG!!

What's the likelihood of a short to ground on one of those wires? What's your approach for shorts, do you do it like the manual says, disconnect plug, check for continuity & resistance? Thanks in advance.

Well God damn, I was about to sell this Infiniti I35 I had with this same issue. Going to scope it and see what I find later today.

nice diag Kieth, have you ever struggled with a diagnosis, you make it look so effortless ,enjoyed the vid

Does it ever turn out to be a bad sensor input to the module, rather than a primary module problem? I'm wondering if you need to go through the effort of disconnecting the wheel sensor input signals to see if the problem persists....

Yay more Nissan ABS issues! They've recalled something like 200,000 odd cars in 2019!🤭

The Godfather is back Keith “EasyPeasy” Defazio. Can this be caused by an input/output to/from the ABS being bad, causing the module to not communicate 🤔

Is that 2.5 to 3.5 and 2.5 to 1.5 can signal the norm for most makes or just this make

so the abs was bad.....did he fix it? Lot of sine wave does not tell me the problem exactly.

Seems like ABS modules contribute to a significant number of CAN bus failures? (perhaps because they are continually exposed to engine bay conditions) Considering how easy the ABS module is to disconnect (usually) it might save some time to unplug them briefly every time a bus problem seems apparent. Also interesting that, in many cases, the failure seems to be front end and exert a positive DC bias to the signals. Hope one day I can't tear one down & find out what is being hosed on these, when I find one. Have you noticed that while ECMs are designed to closely monitor the voltage, current and, sometimes, the load resistance on the various I/O lines, they don't do a great job analyzing the CAN bus lines themselves? A pity as it means any module on the HS bus could leave you walking..

Hey Keith. Is the slightly higher voltage at the end of a message package the signal that it is the end of the message. If you know what I mean.

Isn't the ABS module the first place to look for a CAN problem even without a scope LOL, thanks for the case.

I’m curios,why do you think it’s almost always the ABS module that messes up the signal on the communication lines? I’ve never ran into it myself but I’ve seen at least 4-5 videos and it was always the ABS module.

7th bazinga

Anybody got news where did he go. I miss him

First BOOM!

The car is dirty, you say? You're papers please . . .

Cursed Bosch ABS unit

Too much voltage equals short to ground in the can bus trick to diagnosis is the biased voltage reading in this case 6 volts too high short to ground it's not magic although Keith is a diagnosis wizard lol
