Expert Techniques in Advanced Vehicle Diagnostics: O.B.D. II Secrets Unlocked

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.

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.

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

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.

Wow very intuitive video! im subscribing now!! You are a good teaching instructor 😊

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

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

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

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!

I love all the tips and tricks of knowledge

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

What a gem of class! Thank you 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! 👍🏼

This series is just brilliant, thanks for sharing John.

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

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

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 !

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

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

Thank you John
