I truly have to say, I'm an auto technician. I went to tech school back in 2009, just got into a dealership position about 3 years ago (a large gap of time where technology has truly picked up). What you Paul have done and continue to do as far as these videos with the classes, troubleshooting in the field, etc has been absolutely amazing to watch and learn from. You go so much deeper into diagnosing things, far more than anyone else who I have "picked brains" from in the field. I seriously cannot thank you enough for the amount of effort you put in for those like myself who want to truly become better. I am a big fan, I have subscribed and I will at some point soon be purchasing a copy of your works. You sir are awesome! Thank you!

I've been working on cars for 35 years and I just cant get enough ! could watch this all day . its soothing to the brain. great stuff .

I was a ASE master tech from 1975 - 1985. I quit and started a remodeling/repair business for 35 years. I have continued to perform all my own repairs. Now I'm thinking of semi retiring and going back to working on cars part time. I have fully enjoyed all of your videos that will prep me to take my skills to greater levels. Thanks you for your time and effort to educate us.

I am about to be done with my automotive degree and after watching your videos, I can see how much my local community college leaves out of the curriculum. This video is absolute GOLD. Thank you, Paul.

This is what's called advanced performance diagnostics. Paul is the master, always ahead and top notch. Thanks for the posted video.

Hey man. I have my own automotive shop and I also build racing engines and racecars. I've never had a teacher for the auto world though. Even though over the years I've read alot of ASE books. But people have no clue what it takes to figure things out sometimes. I've watched alot of your vids and I am subbed. Thanks for posting and teaching this young generation

Amazingly informative presentation. Thank you so much! At 58 years old I still find this fascinating. I spent a couple thousand on a nice Pico rig about 20+ years ago and it's amazing how much you can learn just from diving in. I've been out of the professional auto repair business for 35 years but still do a lot of my own work. Unfortunately my rig was stolen years ago but watching this has kind of reignighted my curiosity. I may have to get another Pico to keep me out of trouble 😉. Danner, great job, thank you.

This is the first time I am starting to understand this stuff. I have the uScope and am attempting to learn how to use it. Am signed up to ScannerDanner Premium. I will be watching this video over and over until I understand completely what I am being taught.

Very good teacher....all in good and clear detail you will not miss even a single shot! No trouble can escape with this man,,..all words came out from him cannot be ignored really important,,if I will be one of the students there, there's no way to feel sleepy,,when he started to speak,all came from him is always interesting..no room for drowsiness....thank you sir paul....

thank you SD for been such amazing human and teacher at the same time Im 57 yrs old I used to sell tacos for 17yrs I didnt know nothing about cars now I own to shops recently bought me the uscope and the new pico scope with the transducer and still have the verus pro and I love to see your videos keep doing this so we can continue learnig from the best.

Lol some ones phone went off during class and I praise your patience that you laugh at the situation Thanks again danner

Coil ringing coil ringing was a test to use on fly back transformers in tv work.

Since I have a pocket scope, this class helped me a lot understanding how to use this tool. Waveform interpretation is one topic you covered very well on your book, which I recommend 💯 %. Thanks for all your work Paul. Shalom my brother.

The info on trigger setting, horizontal and vertical parts of the waveform was great. Spark and burn time. I also liked the oscillations at the beginning of the current ramp being an indicator of the presence of a secondary winding. Thank u.

I never learned diagnosing when I did my training and I’m glad you are teaching us this. I don’t want to be a parts changer. Keep these diagnosing lessons comingN

I have the greatest respect for those who teach. Not being contented until there is an outlet for the Knowledge that resides within. I am sure you learn from your students too. Happy Holidays Mr. Danner

Paul is the living proof that when you understand things from their basic principles you can make others really understand them as well. Good job Paul, you are a great teacher! You should pursue a scientific career...if time allows.

You are such a great teacher, theses guys are lucky to have you as not every teacher has the ability to get stuff over 👍😀😀

Very nicely compressed lesson on basic scope operation and ignition waveform interpretation all in under an hour. Thankyou Mr. Danner.

Nice job, Paul. I can remember learning this same thing 40 years ago but it sure shakes the cobwebs loose. The ignition coil looks different today but the theory of operation is still the same.

You explained in detail every waveform line on the oscilloscope patterns and why it's important to know what they represent. Great instruction! Merry Christmas to you and your family. Bill

Thank you so much Paul Scannerdanner. You are the best instructor and again thank you for sharing your premium channel.

Scanner your the man bro!! Keep it up God bless

37:42. Love your content, learn from you every video I watch. Can't appreciate you enough.

Thank you, Mr. Danner. From the bottom of my heart, I thank you.

As usual, GREAT Information presented, and LOVE your style of presentation. Thank You for what you do for the industry, Buddy

Paul - you indeed are and ACE DIAGNOSTIC TECHNICIAN , GREAT INSTRUCTION 👍👍 - Many THANKS ✌️✌️

Hey I don't see any diesel engine videos.! However you are the greatest I've ever seen.

Thank you so much Professor for this valuable information your brother Hassan from Iraq and I am a follower to this distinctive channel in the world of maintenance of cars

Спасибо мистер Данер за лекцию. Способ с токовыми клещами очень интересный.

Love your book and your videos. As a new tech, shocking fellow techs with your techniques, I would love to see a quick reference guide for how to hookup whatever your using for whatever you’re looking for.

Very helpful video, also impressed with the little scope, ordered one thismorning based on seeing this. Been telling my colleagues about scanner danner I love these videos. I get Audi training which I need to fly and costs a lot but this is better

Exelent stuff mr D... No one ive seen has realy explained those wave forms like that...this is one of many i will be noteing for future referance.

God bless you Paul and your teaching methods!!

LOL, your face Paul @ 0:18 when they start clapping. *Light claps* (evil death stare) *claps quickly fade away* Hahaha i know it wasnt intentional just looked hilarious. "Dont you dare clap for Mr Tire while im speaking" 😭

I wish I was 20 again and join you class.

Sounds like your class is growing, standing room only huh, haha that's awesome. Can I get an Amen. Amen brother.

Wonderful video. Thank you for your work and sharing it.

I came across your videos researching a Jeep 4 liter cam/crank sensor phasing search. Next thing I know 3 hours went by. Keep up the good work. BTW, BNC is short for bayonet naval connector.

Thank you for your videos. You have definitely clarified any questions I have had as I learn as I go...

I cannot thank you enough for these great videos you put out. If every trade school in the country had someone like you wow! Also do you have photographic memory?

Excellent vids two thumbs up..kept having a po301 code pop up on my 2001 crown vic lx.. Done everything to it new coils plugs etc...done the water method and low and behold vacuum leak all down the passenger side...thanks alot dude, ive sprayed that sonofagun with carb spray and you name it...finally tryed the water and bam there it was.. I have a new intake already to install, ill post on here if it cures it for good...thanks and happy holidays...

I'm glad you love my comment. I have a 2009 kia sorento diesel. I have to spray quick start In the morning to start and throughout the day it starts perfectly if you can give me an Idea of what to check I will really appreciate it. I live in Trinidad and Tobago.

Excellent training as always. Wanted to wish you and your family a blessed Christmas and a safe and prosperous 2018 . Thank you for all you have taught us techs online with such detailed teaching. God bless you my brother.

Really do enjoy watching your video's. Learnt a lot on theory and approaching any vehicle faults.

Case in point, I had a P0301. Cylinder 6 and 7 had no compression. Also, misfires aren't the only thing that can cause misfire codes. Misfire monitors, in my opinion, can only be trusted to tell you that the crankshaft slowed down. Bad ujoints, bad engine mounts etc can cause the crankshaft to slow down and can cause misfire codes. I've seen it myself.

Another great SCANNERDANNER production!! Nice job, and thanks for sharing!!

Just think back in the day, Every reputable shop had a scope. And when a unit came in for tune-up and/or drivability issue it went on the "scope"

Always a pleasure to watch the best at work! 👍

Excellent. Excellent. Thank you for sharing.

Thank you Paul. Bless you brother.

Thanks Paul! always like to learn from you. I will be re-upping my premium sub as winter sets in.

Awesome information, awesome explanation, and awesome instructor Thank you so much for sharing this valuable video. Please keep up the good work. God bless you.

I swear I was paying attention right here too. haha Really enjoyed the video, thank you!

Hi Dan, will be great it if you come to CA to make a scope class.

The video is gold. Thanks for uploading this.

Merry Christmas and happy New Year May the Lord bless you all with happiness and joy

Dan you the man with the plan.

I have a wrangler 2012 3.6 v6 with diagnostic codes P0201 P0202 P0203 P0204 P0205 P0206 all six injectors circuit open active. I only replaced the oil cooler and it was running perfect before the job. Now it is miss fire counter injector 1 and 2. I scoped the ecu pin 8 and 9 C2 connector and 8 was clean but 2 was messy. Any ideas as to where to look. I have repaired some open wiring from previous guy working on it. Thanks

Mr Danner, good afternoon. how to diagnose misfire caused by spark plug gap? how to determine the correct spark plug gap when there is no possibility to change coil charging time, or any other parameter of the ignition system? Thanks in advance.

Thanks happy Thanksgiving

I can't make up my mind between buying the DSO, Hantek or the Micsig TO1104 Oscilloscope. The Micsig looks awesome. Can't afford the Pico. Great video.

This is great. I wish I could take your class. From Upstate NY

Pretty crazy to think how fast the computer has to work for it to calculate single cylinder misfires wile the crank is spinning at 800ish RPM! And in my experience they are pretty damn accurate, especially on the newer cars!

I now want to take the time to wish ya'll a Merry Christmas and God Bless all of the youtube community!

For an intermittent misfire what test(s) could be done with the scope? No one in my dealership can use the new mopar special tool : pico scope. I want to get proficient at scope usage

Excellent vid. Wee question. On the secondary circuit you said there was a fault on snap acceleration because the first vertical line didn't rise, but then straight away when you tested another hv lead and the vertical line went out of the screen you said it was because of a misfire.

Excelente clase master .mucho saludos desde chile

1:53 I can't figure out why some of the DIS ignition systems' waveform(s) look that way . Low firing lines falling that way I would truly appreciate an answer, ive been searching but havent found anything

Great lesson Paul. Thanks!

You're an awesome instructor thank you I just now subscribe

Pretty good scope info in this one.

Rất hay và bổ ích

hello there.....I have a buick lesabre 1995 that has the same engine 3800 in my car and I am dealing with 2 misfire.....The number 4 cylinder ignition coil isn't firing at all and cylinder number 2 will sort of spark but not like consist like the rest of the ignition coils......First I tried swapping coils around but the problem didn't move at.....the coil that I thought it was bad (after switching them around) was good so my next step is the ignition coil module system.....After putting a new ignition coil control module in it I am still stuck with the same misfire.....I even put new spark plugs wires in it (since I change the spark plugs last year and forgot to get new plug wires) nothing change at all.....I even bought new ignition coil pack all three of them and the problem is still the same........I wanna know whats my next step to pin point the causes of 2 misfire that I'm trying to fix......thanks..... love your videos keep up the good work brother.

Thank you so much I learned and enjoy this video!

Just bought your first scope ? Just thinking about buying one ? Already have one but not making use of it ? This video is a gresat starting point for using a simple oscilloscope for secondary ignition misfire, More at www.scannerdanner.com

Well i crashed and burn on a Toyota i fix some wires that was cut and had number 2 miss fire, put new coil and done same. Friend said i should swaped injeters i think in engon

hello friend I congratulate you for your support in the video and I write to you from caracas, venezuela I have a dokota V-8 2912 automatic I have a fault my trasmission "does not back off, but if it starts well

This is a good video because a possible trans code is there and I've been wondering, how far do you take it with transmission codes? Do you send it to the trans shop or do you see if it's engine related. Maybe a video on how you proceed and the distance you go.

great channel been a follower for a long time recently stumble into a job that's got puzzle 03 Nissan Murano v6 replace the engine with the same from another 03 Nissan Murano when finish when to start n had code P0345 replace camshaft sensor nothing check connector red wire read 12.20 black wire was also good reading middle wire signal while in idle in ohms read 5.15 open valve cover from old engine n new n they look the same however when i turn it on it barely has any power at all can u help or point me in the right direction

How could anyone thumbs down this video? They must be parts changers

time :34.29 its actually back emf that your seeing as on oscillation rather than reserve energy its actually wasted energy as it is not big enough to produce another spark

Would a engine burning oil and making a rich condition cause a short kv firing line on a snap throttle

Wouldnt coils like headlights draw uneven current( old vs new)and recommend all new electrical stuff

Thanks Paul for share this video is very informative =) Regards from Spain.

Thanks vidio

Absolutely fantastic! Wee Q. If individual coils are difficult to get at and (by the sounds of it) only 1 wire powers all coils, how do you condemn a specific coil? Thanks. N/W Scotland.

Thanks paul Danner

Hey Paul will you be attending Vision Tech in Kansas next yr ?

have you used the GTC505? would be easier and faster to check ignition systems. sec, prim and current ramping

Hi Mr Dinner, I hope you are in health? I wish you happy Christmas and new year.

Thank you very much! Paul..

@scannerdanner I have a capacitive pickup that is very similar to the one you use. I use it with my verus and a small handheld similar to this one. It will not show nearly as much detail with the spark event as the ones I have seen you use. Connections are correct. Do you think it is just because it may be a cheap knockoff? Thanks, justin

mr can you tell what kind equipment you are using tank for sharing with us

Dan is it possible to detect misfires on control O2 sensors values alone? For example, we have a wideband probe precat and narrowband postcat for control. If the control probe is periodically hitting really low numbers (like 0.1V), can this be an indication of a misfire, too? Let's say the manifold and the exhaust is absolutely leakproof...

14 people are parts changers! Lol

The plug wire clamp @ 8:20, does that come with the U Scope?

Hi Paul, what type of screen are you using that will allow you to control your presentation like that?

good master i need snap on but i spechalaiz on peugeot cars i am comfuse pls help me out

You say in class: “no primary coil osculation, means you have secondary coil problems”. It should be you have a “secondary problem” could be the coil, plug or cable (or combinations). Thx for this excellent vid!
