Thank You for sharing your knowledge, Great Video. I hit the bell !!! I’m not a tech , mechanic, Etc . Was getting frustrated a year ago with a P0304 code . Spent way too much money , having my vehicle diagnosed . Decided to try to educate myself and find out what causing misfire . I believe in paying for a diagnostic tests , but when you find out wasn’t test driven , cleared codes , freeze frame data ETC $1200 bucks later engine light flashing after 2 drive cycles (Ford) ! Misfire gone for 8 months , fuel trims , MAF , EGR , Etc all working as they should again . I continue to learn as much as possible, my new hobby . Love when my husband, kids , ask me any question about their vehicles . Thanks for sharing a fantastic, informative, show ! Watched twice !!!! 😊 thanks from 🇨🇦🇨🇦🇨🇦🇨🇦🇨🇦

I’m trying to be a more efficient technician and these videos are really helping. Thank you!

Love the brain candy! Besides being a great instructor and presenter your video production is a breath of fresh air. Thank you!

Thanks!

On the global side of OBD2 are the fuel trims live data? I didn’t think they were actual readings but come from fuel mapping programmed from the factory in the computer?

Of course we are interested on long, informational and professionally presented like yours. I have been doing this type of job for awhile now and I can honestly say that in the few videos I have watched on your channel is very easy to tell you are dedicated to this trade(profession) and I really appreciate all the classes you put out there for us to watch.

I'm a DIY. I just learned a LOT. Thanks. And I hit the bell 😂

Thanks John. As a professional tech I learn a lot from this video. There's power in sharing.

Thanks you for the knowledge you gave to us bro

Dang bro, I taught my youngest about OBD2 in less time.
All I see is you talking about your program that costs money each month to tell you whats wrong.
Any decent scan tool will do that.

If you dont know what you are looking at or what the tolerances are, that scan tool will be speaking greek.

Thank You John, excellent video's, please keep them coming

Thanks for the excellent information,

Awesome stuff

Good Job John. I worked at GM (chevy) for 31 years ...Flint MI. Various jobs in emissions related federal certification. Never had a dull moment at GM !

you got yourself a new subscriber! Love the explanation, thank you!

JOHN, AWESOME information you been sharing thanks for the time and effort to do this really appreciated brother. cheeeers for On, Canada

please keep making videos. now that the series is complete, perhaps practical application and diagnostics videos

THANKS AGAIN JOHN, especially for explaining the Mode 6 global obd side. Please continue with Diagnostics contents. Have a wonderful weekend.

Comprehensive overview ! Incredibly clear descriptions !! Seriously !!! Thanks mate 👊🏼🔥 .

As a DIYer this is exactly what I've been looking for to gain a fundamental understanding of how OBD2 is built, how it operates and therefore how to interpret it's data on a wider view.
Very well presented. Thanks very much. Instant subscriber.

Great content like the global obd explanation

This is probably the most comprehensive video. I’ve seen on OBD two systems can’t thank you enough for the presentation.

amazing im a retired master tech,but still need to go to class.thanks

I am grateful to have access to such knowledge and be addicted to it. My favorite drug (driveability and mindset diagnostic)

Good Stuff! Great Channel! L & S

Great job. Took a bunch of notes. I watched all 3 videos in one day. Would love to see some real world testing on cars that have a drivability issues. If possible in your upcoming video on fuel systems, would love to see a way to trouble shoot restricted injectors, with a scope, amp clamp, scanner , etc. Something that doesn't require pulling the rail and firing the injectors. Just got my but kicked on a Prius . My guess was right, I knew it was a fuel delivery issue. Eliminated fuel pressure- lean across the board but only misfired and ran poorly at idle. Lean codes in general when its not a vacuum leak and fuel pressure is good and load sensor is good. BTW- I do remember block learn and integrator from back in the day. Thanks again, keep em coming

Great job john

Hey John, I just subbed to your channel, been looking pretty good so far with good accurate information. I am looking forward to your next videos. Keep up the great work! 👍🏼

Wow very intuitive video! im subscribing now!!

You are a good teaching instructor 😊

What a gem of class!
Thank you John!

Thank you John

Your channel is my new favorite as a self taught mechanic. Plenty of depth and background explained but not overly complicated explanations. Thanks! The AI chat bot was a trip playing with it the other day!

Of course there's interest. Thank you so much for sharing all that you've learned over the years with ud all. It's very much appreciated.

I just can't wait for the next episodes and especially the one on decoding CAN.

Keep up the excellent work, it is awesome as it is.

Thank you for sharing this information! Very helpful for those of us who want to learn! Can’t wait for the CAN system video!

Electron John should have thousands of views. This goes to show you the mentality of the DIY'ers and a few legit professional techs. They don't want to learn and gain understanding but instead they just want to know how to fix an issue with zero understanding of how the component or system works. What's wrong with this mentality? It's further encouraging parts replacement with a good chance that the problem is not fixed. Other words, loading the parts cannon and crossing your fingers. John, I would like to THANK YOU for what you share and teach. You're top notch in my book sir. You make complex concepts easier to understand.

This series is just brilliant, thanks for sharing John.

I love all the tips and tricks of knowledge

I'll be waiting patiently for the 5 gas video!

Thanks for this educational video as always. You are on mission to really better the automotive industry.
