I can’t take credit for the video part except for making the investment in equipment. my nephew is the talent behind the scenes with camera shooting, lighting and editing.
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.
thank you for your continued support in watching this series. I have a lot of ideas planned and as long as people continue to watch and have interest, I plan to keep releasing them. thank you for the kind words again.❤️. much appreciated!
Yes! You see a lot of what I did when teaching. Students and working techs (had both in my CC classes) just wanted to know the most common faults, but did not want to learn how the systems worked. Another key is reading and understanding wiring diagrams/schematics (to my mind once a fault is detected then the schematic for that circuit should be pulled [preferably OE if available] and analysed, to help isolate the fault.)
@@gregwarren8583 hi Greg, thank you for watching. I agree, understanding how a system is supposed to work, is the most valuable tool one can use to diagnose a problem quickly and efficiently
Mode 6 data can also predict the future. I use it to look at the hex decimal numbers to see for example if the catalytic converter is about to set a p420 code. It’s also invaluable for diagnosing no code drivability issues. Most scan tools cannot display the data needed. And it requires the manufacturers conversion numbers to make sense of the numbers. But if you can master this one mode you’ll become a next level diagnostician.
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.
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.
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!
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
Billy, thank you for watching and the kind words. I will try to incorporate some hands on testing for you in the fuel video. I have been thinking of doing some of this but was afraid the video length will be too long and people may not want to watch, but I will give it a try in the next video. thanks again!
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 !
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! 👍🏼
hi mike, thanks for subscribing and commenting , I am grateful to all of you that subscribe and comment letting me know which direction to take my channel in.
hi John, we have a fuel systems video being uploaded as soon as editing is completed. next we will have a battery and starting and charging systems video being uploaded then the third video will be something called quick check diagnostics. I think you may really enjoy the quick check video as it pertains to practical diagnosing various issues. thanks for your support!
Having watched months of other videos, you have showed me how much I have missed, thinking that there is so much that is assumption after gathering info from meters and scanners, this is something I am not used to, my trade was working on electronic service repairs for the marine service and using an oscilloscope was an everyday occurrence using scopes worth thousands of dollars, even our cct diagrams had expected wave form under different conditions. Having used scan tools, I recently bought, it still left a lot to desire to repair a car, Having only watched 4 of your lectures has just opened everything up, as sone as you pulled out the scopes and showed the waveforms, it now is all starting to come together and making sense, thank you so much, if only we had the $200.00 multi lead scopes back then. We had to use a Polaroid camera with special adaptor to go on the scope to save images. LOL
thank you for watching and commenting. your words of encouragement came at the perfect time when I am reading a comment from someone who is attacking me with their comments. I will always take the high road however and not stoop to their level and I will surely continue to support my followers with new content. thank you again!
@electron-john There's always going to be that guy who thinks he knows it all with a big mouth and a keyboard and all for a lil publicity and attention.
@@electron-john Sorry to hear that. Unfortunately there's always going to be haters. Luckily it's only a few. Misery loves company so it's best not to stoop to their level and you already know that. Just ignore them.
Thanks for taking the time to do this. I'm a DIY'er and felt like I just took an Auto Tech class at the local Tech College. Great explanations and on showing how everything worked together. That video didn't feel like it was 47 minutes long. I've learned more in that 47 minutes than the past several years trying to find things on my own. You're doing God's work here my friend!
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 🇨🇦🇨🇦🇨🇦🇨🇦🇨🇦
Thank you Sir , for sharing your knowledge to us, truly beneficial to those who would like to continue to embrace this trade & technology as auto technician.looking forward for your next video series,Deeply appreciated 🙏God bless.
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.
Really appreciate the time & effort & patience you put into these professional presentations, thank you....... But I always think, Is IT REALLY NECSSARY TO MICRO MANAGE A CAR TO THIS DEGREE? !955 cHEV WAS GAS IN AND GO, NO problems
Good basic tutorial on OBDII. Glad to know you will explain more detailed information in some future videos. It is critical to know the intricacies of scan tool data so that you can double check or verify a fault & its repair. I took a course in automotive technology back in the late 80's, and since then I had to read multiple books & articles (Motor) to understand how OBDII worked. TH-cam techs like you have filled in the missing pieces. As more techs & D.I.Y.ers come across your channel you will definitely get more subscriptions.
Just subscribed after finding your channel. I just bought a scanner and trying to learn as I go and I think I have found a great teacher to help. I am just a DIYer but am interested to know how these systems woork.

Hello Electron JohnEDC. 17C55 I have a Mahindra tractor 2021 with a Mahindra ECU Model EDC 17C55. Do you know what scan tool works on it? I have the typical OBD2 connector and its a 4 cyl diesel engine. Thanks Mike
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?
There was a OBD1.5 used by GM. My 94 z28 will not scan on OBD/OBD1 pin connector is for OBD1. Jumping pins on plug will not give code on the CHECK engine light on dash.
try checking the fuses to. make sure none of them are blown. also those earlier systems would sometimes use a check engine light driver module. just some thoughts from an old man.
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.
just so we are clear, at no time throughout the video did I ever talk about, nor do I have a program that costs money each month that tells you what’s wrong with a car. I am giving away years of my experience for FREE and I have to get attacked by you? thanks for watching
@electron-john Yes you give advice but the program you use costs money each month. You feel attacked ? 🤣 If people don't know the tolerances that are allowable on the sensor, how will they know if its bad ? I had a guy tell me my alternator was bad for pushing out 13.8 volts. 🤣 He said it should be 12 v max. When people don't understand, they will get it wrong, regardless. I'm not attacking you or your "years of experience". I give free mechanical advice and services too. I watched the video and was bored. You repeated yourself numerous times and talk too slow. That's not hate either. 😂 Show the scanner in use and go from there with the explanation.
again, what program are you talking about? this video was on global obd 2. that comes free with any scan tool. everything I discussed in the video was pertaining to how something works, at no time did I promote something that costs money. if there was an ad that popped up, that was not me. and yes, maybe you don’t like the video because of me and my talking slowly or whatever else you said but I personally would not go to your channel about coins and say what I didn’t like about the videos you have, I would just simply move on . again thanks for watching.

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?
so the fuel trims are actually mapping values based off of exhaust oxygen content readings at various dynamic operating conditions.
