Hi Man,
for time being I am very interesting on Automotive electrical part so if I join you will I get training and help on that will you provide me prints for various make and model or where I can buy

Service information (wiring diagrams and flow charts etc) are not provided as part of this training. The service information program I use (MitchellOnDemand) runs about $160 a month. I do have a DIY link that you guys can use that runs $20 for a months access for a single car
But as far as an SD Premium subscription goes, you will not find this type of training anywhere, especially for $11 a month. Pennies on the day my friend. Thanks for your interest!

I will let me keep it short and simple I wish I knew exactly what you know and diagnosing electrical problems on cars I have seen many of your videos and the way you teach inspires me despite all the negative comments I might get from other people that seen me trying to fix my car At the moment I don’t have the Money to buy your book but when I do I Most definitely will I hope to learn many things from your work no doubt about it I am here to stay and Getting the same knowledge that you have because this is something that I am into as they say you will never work in your life if you do what you love

I have been an auto mechanic for 3 years. I have been searching for something to help me gain a little more competitive edge in the industry and help me be worth more as a mechanic. I have been frustrated with the shop I work at and their way of "guessing" what the problem may be. I have only watched one video so far, and yet I am sure that this is the information I have been looking for. Paul gives excellent instruction and I have already learned a few things that will help me be more accurate and quick in my diagnostics. I'm very excited to continue. Feels good to be learning again.

18 November 2020

I love the teaching method of attacking each problem from every single way possible. The more ways you can test a fault the better you are at finding oddball ones. I really enjoyed the videos on this channel.

I wanted to know if I could use all lessons in the heavy equipment field? Thank You for your time.

Absolutely! I would say a good 75-80% of the material that I have directly transfers to the diesel market, in fact other markets as well! . Electrical and electronic troubleshooting is no different no matter what you are working on!
Thanks for your interest!

Just wanted to say your videos have replaced Netflix for me! Watch them nightly . They put me to sleep much faster , only kidding. They are great!! I am not a mechanic by trade , I am a Locksmith, I got in to reflashing some vehicle Modules( mainly GM , Ford.) for local mechanics. Started watching your videos To learn how to test systems.
You already made me money! 2002 F150 no comm , Wiggle test around the fuse box found a
Pinched wire behind the Cruze control motor.
I ordered your book and will be stepping up to the premium after it arrives.

Hi. I watch South Main Auto videos on Youtube. On occasion Eric mentions Scanner Danner videos. I watched one and I was impressed.

I'd like to read or browse your book. I went to Amazon to find it, but it does not seem to be available: and"Paul+Danner"&i=stripbooks .

I see there is a way to buy the book from the website, but I don't trust you or your payment processor (yet). I don't want you or your processor to have my credit card information. On the up side, I trust Amazon and they have my credit card information.

I think you should consider selling your book on Amazon. Amazon is one of the largest bookstores in the world and you will reach a wider audience. Amazon availability will also bridge the gap in trust that exists because I don't have to trust yet another external entity with my banking information.

Thanks in advance for considering Amazon.

And thanks for the videos. The videos look interesting.

We use PayPal for all of our transactions. I will not and do not ever have your credit card information. Also, you do NOT need a PayPal account to purchase either the eBook or paper book. Our paper book sales are handled by AESwave, so if you chose that option, you will be redirected to them. They are THE most trusted company in our field. Ask Eric O, he will tell you the same thing.
Unfortunately, I have no plans on selling on Amazon, they take a huge commission to do that and I just simply do not need their platform to market my book. On occasion, my friends at AESwave have sold my book through Amazon, so if you see a history there, it was from them. But again, because of what Amazon takes, it is not worth it.
Hope you reconsider. Thanks!

I need to change my payment method due to CC fraud. It should be under Membership Subscription Information. I've dropped every window without results. Please assist.

Okay you deserve 5 stars. I have only one suggestion. Waveform library. I know iatn has one, I know Facebook has groups, auto nerds, pico , ,etc.

I think a place where everyone that visits your page can upload their known good waveforms and view others would compliment your premium customers experience. Keep up the awesome work you’re doing for automotive community

Hi Paul,
Love all your stuff. I enjoy reviewing the vids and I'm getting better and quicker with my diagnostics. My customers are getting better service and I feel a lot more confident when I call a bad sensor. Thanks for what you do. It's a great resource for me.

The 5 volt reference was my problem on my Prelude input side . Thanks for all the good information I was able to get my car up and running I'm going to continue the course all the way through. Thanks

is it possible for someone with not much experience working in a garage to go through your course, continue learning through other methods, etc. and possibly be out on their own, doing mobile diagnostics?

No question in my mind. If you have the mind for this, I can teach you. Sign up for the 14 day free trial, watch the Navigation and where to start video on the premium home page and check it out for yourself.
Start in Chapter 1 or in my basic electrical classes.
Thank you!

Just watched your Allison speed sensor video. Very helpful. I have similar issues with my 4060. Speedo erratically high, harsh downshifts, and unable to keep cruise on. I’m going to order the output speed sensor and go from there. Thanks!

Thanks for all the training, this is excellent! I am a newbie, and want to open my shop in Mexico. Many of the tools that we use here are lower in budget, but all of the techniques that you teach are the best! It would be great to be able to get a printed copy of your book in Mexico, I dont know if you do international shipping. I learned from you watching schrodinger´s cat, a channel in youtube from a very effective do-it-yourselfer, congratulations!

REPLY FROM ScannerDanner:
Thanks so much! And yes, we can ship a book just about anywhere in the world. AESwave is my exclusive paper book provider and you will be redirected to their site if you click on the Buy the Book tab on my site.

Dear Mr. Paul Danner, I appreciate your hard work. I am from West Africa, Liberia. I want to subscribe to your premium subscriptions,but I don't have PayPal account. What's is the way out.Please help me.

The only way to subscribe outside of PayPal is to pay for a 6 month ($66) or 1-year ($132) subscription upfront. We can send you an invoice that you can pay with any credit card. It will still be a PayPal invoice but you will NOT need a PayPal account to pay for it.
I can also open premium up for a few weeks for you first, to make sure it is what you are looking for, before paying for anything.
Let me know what you want me to do. If you'd like the free trial, I need you to sign up for an account on the home page of my website and then send me your user name. DO NOT sign up for SD Premium, just a free account from my home page and email me your user name. I can then open premium up for you on the backend of the website. In the future please do NOT use this feedback page for this type of stuff, email me directly at

14 September 2020

i paid for my subscription on 8-14-2020 and it wont let me see anything. what gives

Miguel, as you have already found out, this is not the place to get help for these types of issues. For others reading this, please email for any login or payment issues. We take our customer support seriously and my wife and I are the only ones who handle our support emails, so you can be confident that you are speaking to someone who cares.
Thank you!

I’ve been in this industry for 35 years, L1, X1, ASE Master Technician and just recently a subscribed member to THANK YOU, for every video and all of your training courses. I get to learn and add to my skills and get a refresher every time I tune in.
I like that you are humble and laugh every time when you speak on the “PO” vs the “P0”, I use to correct my trainees and employees about that all the time. Another one is saying “VIN Number”, I tell them saying that is an oxymoron, VIN is Vehicle Identification Number not Number Number. Hahahahaha!!!

One other thing, I as a long time Snap Scan-Tool user (Verus Pro) welcome you to my club as a Master Technician that is also learning as I go with the Autel MaxiSys Ultra. Great device, lots to learn. The WaveForm Generator feature has been a game changer to my diagnostic game.

You and Caleb are a great tandem adding your Brother in at times makes the experience great. I love the bond you three have.

Keep up the GREAT work Paul Danner, Blessings to you and your entire Family.

My 2006 Grand Prix will crank but no fire to the fuel pump. I’ve installed a new pump, changed relay and checked fuses & changed the exterior fuse box but still no power. I can jump the pump at the rear and get pump to run and disconnect then try to start and car will run shortly. What do you think the problem might be? The only thing I have not changed is the crank & cam sensor and ignition switch

My question is why do I not see you using a high dollar fuel pressure/volume gauge.
I am considering buying one but do not want to if it is really not necessary there is a million other tools I could use.

Hi Paul,
I have been watching your videos on YT for the past two months and I can say that YOU ARE THE BEST OF BEST. I wish you all the best. If I had lived near PA I would definitely met you in person. My background is in IT, but I love to know how to diagnose a car logically by applying science and common sense.

I would just like to thank you for sharing your knowledge with everyone! When I started my 2 year automotive program, I quite my job and opened a mobile mechanic business to help me get through school. I have used your knowledge along with my teachers at Wenatchee valley college to build my business from the ground up. I started with a rusty old truck and a few tools.I now have a small shop and a fully functional mobile service van. You have made my dream of owning an automotive repair business possible. Seriously thank you

You've taught me more about my scanner than any snapon video's I've seen to date.
I watched all there's at least 3X's and they didn't teach you anything you should of already known. They sell a high tech scanner and expect you to know all about it. Thank you, John

I love what you are doing here. It has helped so much. I have had to pick up alot of slack at my shop bc our lead tech got fired. Now I'm next in line. So alot of pressure for a 25yr old who's trade school teacher sat in his office and never gave lectures. Up till now all my diag skill has been self taught. So thank you again. The only thing I could ask for from this channel is away to know where I'm at in a video or which ones I have watched. I'm very busy and most of the time don't have time to watch a full hr video. Again thank you for all the lessons.

I am a mechanic by trade. I am 48 years old. I started my mechanical career in a machine shop. I worked on pneumatic and hydraulic systems there. I then went to the auto field for a few years. I was only able to learn what I could pick up from the more advanced mechanics in the shop. so I moved on to work on Industrial equipment such as Forklifts and Aerial equipment. I was able to take a five year course while being there and many Factory direct training opportunities over a period of 16 years. I now work on earth moving equipment for the last 5 years. Caterpillar, John Deere, Volvo, Terex ect. over all the years that I have worked and had training, no one has ever tought me as much or as well as Paul Danner has. People are so very blessed to have this man make this type of training available to the. He is changing the world and making mechanics better all over the world. his training has helped me in so many ways, I just wish I could have had a trainer like him so many years ago. its been a very hard road to travel because I missed out on this type of teaching. I have been tought by many factory direct instructors, but not anywhere close to Pauls

15 December 2019

Greetings. I appreciate the effort you put to make everything work. I have been going through the test papers. they really make a difference in enhancing my understanding. However, they dont seem to cover all the topics as they only extend to week 8. Can more of the papers be uploaded if available? Thanks and have a great one.

You will find chapter review questions for all the chapters in my book in those 8 weeks. My class at Rosedale Technical College is 8 weeks long and that is why they are segmented that way. Thank you!

how can i get an answer from you when i had a question working on a car problem
As you can see, this feedback page is not the place. Use my forum! It is free to join and I have paid moderators who are there to help me help you guys! If you have a specific question about a Premium video, you can post those in the comments sections of the videos (just like YouTube) and I will answer those. If you have specific help requests for a car you are working on, again, those need to go to the forum. I cannot keep up otherwise. Thank you!

discovering SD and joining SD premium was the best decision I have made since I can remember, it didn't cost alot for premium but has transformed my understanding of vehicle electronics beyond what I would ever have been able to discover by my own experience.
once you are equipped with the knowledge on offer here it builds confidence, and the fix success rate goes up along with efficiency. and you start to enjoy not being frustrated the same way.
if you really are hungry to learn join up and run with it you will be glad that your historical self made the decision ?.

I'll tell you what... my diagnostic capabilities have come so much further than I ever thought. Last week, solved a no start issue on a 2001 mercedes c320. Found there to be no voltage going to several modules in the vehicle, with no ability to communicate etc. Was able to trace voltages back to the front SAM using methods I have learned almost completely from scannerdanner. Resolved the no communication/power issues and still no start. Then found a faulty relay that was activating, but only allowing 300 mv to get to the starter relay. Without his teachings, I wouldnt be able to make the money on the side that I do. It's amazing the difference it has made.

7 December 2019

Before scanner danner I was working in a dealership replacing parts according to codes . One day I was working on a older dodge ram and couldn't figure out why the fuel level wouldn't read . Then I so happen to stumble upon a guy teaching students in a classroom how to diagnose a faulty tank sending unit. I was able to diagnose and make money on that repair. This video is what made me realize I needed to better myself. Soon after I'm watching every free video I could of mr paul danner. I work on mostly medium and heavy duty fleet vehicles , mostly diesel and some gasoline. The foundation he provides works on a wide variety of vehicles . I then told myself if I'm learning this much on the free videos I need to invest more time and money to get myself to the next level. Once I was into chapter 3 I was testing and understanding circuit design on the vehicles at work instead of grabbing parts off other vehicles and guessing. I took an even bigger plunge and quit my job to work in the oilfield industry. I start off this job fixing trucks that everyone just gave up on and that caught the attention of the shop manager. Months pass and I'm fixing more vehicles in a week vs the guessing techs in a month. Replacing parts that fixed the vehicle the first time. Soon after I'm placed as foreman and every job since, due to my ability to diagnose and helping others to diagnose and taking the time , to help them understand why I came to the conclusion of the diagnoses. Right now I'm moving up to being service manager. To sum up this long story I really encourage you to take time and invest in your life because paul danner changed my life. My annual income tripled since I invested in scanner danner premium, if you take the time to learn then there shouldn't be any reason why you cant better yourself. Thanks paul I owe my success to your training and I will never forget that.

I went to school at a well known technical school for automotive tech and paid a lot more for a lot less information than Paul Danner gives you on this site. The premium course is well worth the subscription. Skip the expensive technical school and just pay him. He's a better teacher than what you get with the technical schools, he is more professional, and you can learn at your own pace without all the distractions of the dumb guys around you who aren't there to learn.

Awesome content Paul! Been a premium member since your scanner Danner premium channel on YouTube began and continued to be on your website! Not planning on canceling anytime soon. AVI on demand charge over $100 per video for 1-3hr content on many videos, it is very good content I’m not going to lie but yours is as good as theirs and with 1 purchased video from avi you get a whole year subscription at your premium site! Can’t beat that infinity times! Lol. Thanks to you and your online class I’ve been able to diagnose cars even “technicians” with “years of experience” haven’t been able to diagnose. All credit goes to you Paul! Thank you!

16 November 2019

too many things a learned.

Paul, hey, new member to premium. I've been watching your videos for over a year now on tube almost enough to think we'd be buddies. Hoping you might know a way to get ASE coupon/voucher A1 -A9 certified wanting to take L1 this week, know I can pass after your training :-) You guys are the Best!

Maybe you are one of the kind out there approaching problems like this and that's makes you special.I've learned a lot from you so far yet have a long way to go and i thank you so much .One thing i would like to see more from you is doing your diagnosis with different tools.I mean you use all these fancy tools and that's perfect,hope that everyone could afford that,but i would like to see the same tests at the same case using also more simple tools but still be in the same range of accuracy.
Hope you all the best keep up the good work.

3 October 2019

I very much like the site and the way you are teaching. Your passion for cars tells me you really care about you students and fixing the car right the first time .
I am trying to learn the pull up and pull down circuit .the one example you are teaching is on a ford with the fan running all the time My question is does this also work on a car the has can wires that are also going to the fan . example 07 Mercedes C 280 has 4 tires power ,ground single and can wire , will it work for that car , and if so do i perform it the same way thanks Ray

29 September 2019

Absolutely love this program. I really enjoy learning new things. Education of high quality costs big $$$. This is the best value possible. The feedback I would recommend is a way to not lose your spot during the lessons. When I have to stop watching and return later, sometimes i am right where I left off. Sometimes I have to restart, and there are so many lessons, it’s easy to forget where you were. I’ve started taking screen shots of my current lesson when I take a break. That way I can pick up right where I left off! Thanks

Anybody thinking of signing up to scannerdanner needs to stop thinking and just do it. Paul, I just want to thank you mate, since qualifying I've been in the field for just under 3.5 years. I work for a Ford dealership. In that time I've been watching your videos, purchased your book and spend time learning every night after work. I've gone from being the know "nothing" newbie to being a diag tech with people who have been doing a lot longer than I have coming to me for guidance/help. I've had over 9K in pay rises since I started and next year I will be starting my masters training, were I'll get even more money. And I kinda couldn't have done it without you. So thank you from the bottom of my heart and keep up the good work my friend.

Don't be a parts changer, be a scannerdanner student!!

27 September 2019

Hello Paul looking forward to learninig alot from you.

"Eric the Car Guy" turned me on to your youtube channel. Your S-10 96-2002 spider injection bad regulator case study helped me tremendously.
I recently did a stock 4.3 V6 engine swap and i have few wiring issues.
I'm a shade tree mechanic in my 40's mostly do minor repairs on computer engines for friends and family. Grew up on carburetors and still do Carb work. Never been to trade school so taking the time to learn at your online trade school. My computer diagnostic skills needs work these cars keep getting more complicated. Thank You for putting content out there and spending the time to build a website and make so many videos. Your camera work is amazingly clear, mic is crisp and your explanation of electronics is easy to follow. The projection screen in the classroom is really neat and great tool. I have a separate career from automotive so I'm not going to spend time or money at a tradition trade school I'm married with kids don't have time. But now I can study and learn from your amazing website in my spare time. Thank You again and looking to be a long time subscriber! Cheers

Love your website and YouTube videos...
Just watched your YouTube premier on the KIA Sportage body control module... I was wondering if it would be an option.... before messing with power and grounds at the body module to disconnect the battery at the battery and connect the battery cables together to bleed all power out of all the systems to see if the module acts normal... this way you would not be touching any connections at the module....

this came to as a question after i watch your video.....

Thanks for doing what you do... :-)

If anyone is reading this right now, you should absolutely subscribe to ScanneDanner. Its a minimal investment with a huge return!
My name is Fred, i have bean working on boats for 25 years. I have been to many classes for Marine Engine systems and worked with many different technicians in my field ranging from beginners to Master techs. We all had a very similar way of diagnosing ( hanging upside down in a moldy bilge, holding on the back of a boat trying to read a volt meter or scan tool while under WOT on the water, very dangerous or CHANGING PARTS that were hard to get to to find the problem).
I thought i knew electrical, thought i knew how to diagnose until I stumbled on Paul Danners site ( ScannerDanner ) by accident 3-4 years ago.
It changed my life!

Thank you Paul!

Paul, your book and videos give me a new Direction in my life what I want to do and what I want to work. At the moment I'm working in building but after when I buy your book and when I watching your videos I really want to became a professional in diagnostics.
life changing, Thanks.

Not able to access product purchased more than twice. And the support reply is very slow. Not happy with product or service.

Peter, you have a spam blocker in place that's preventing communication. For anyone else reading this, if you are using one of these, please add as a recognized contact BEFORE you contact me!
Peter, I can see that you purchase my eBook on 7-4-19 (just a single purchase) and then emailed me the next day asking for your eBook license code (which is automatically sent, after your purchase from bookguardpro and was probably blocked by your system as well). I promptly replied to your request on the same day with this information but my reply email was blocked by your system. I just attempted to email you again, today, after seeing this review, through my personal email and hopefully you will get that one. I have no problem with a refund of the eBook, as you state in this, that you are not happy with the product. As far as the lack of communication goes, this is something I take great pride in is helping my customers personally. To others reading this PLEASE ADD as a contact! These spam blockers are a HUGE frustration to me.
Last comment to Peter, I will make this right for you. Hopefully you will at least see my reply here and contact me again after approving my support email as a contact.

hello everyone, I felt compelled to leave some feedback here. I discovered paul around 3 years ago and and started to watch and learn, I felt like my eyes had been opened to a world which seemed beyond my reach (electrical diagnosis). since the time before "scanner danner" and now my wages have increased around £7 per hr which I mostly owe to paul and the confidence I gained from him although hard work and investment on my part. point being if you really commit to learn, this is the place to do it, it worked for me and I owe so much to paul. good luck to you all

Hi sir! I'm hasanal from the Philippines I'm your number one subscriber.. I'm very glad that your channel help me to understand some difficult and common problems of troubleshooting a car unit the latest and the oldest cars.. Somehow I have none of these scanners and meters to be used I can't afford.. But I'm very happy and satisfied a wonderful and nice explanation that easily catch up my learning capabity.. I wish that this channel will conteneusly exist and have a better way to provide to some that ignorant of this kind of technology... Thank you God bless...

Paul, thank you for putting together this valuable resource. This is satisfying my desire to learn, can't wait for school to start back up.

Perhaps it would be worthwhile to move the basic electric concepts to the very top of the listing of the premium videos as a starting point for those that need it or wish to review before jumping in. I know you mentioned in your introduction video on where to start that a subscriber withdrew because they felt the concepts were too advanced. They may not have watched your 'where to start video' or not noticed the basic electronic concepts. Repositioning will put it front and center for new joins that may benefit from the basic electric curriculum.

I have been studying Paul´s material for the last 6 months. My expertise level has gone from 5 to a 8 and I´m still learning and getting better every day. I have been working on cars since I was 14 but now its my main source of income, I do mobile diagnostics and repair.
He´s very good passing on his knowledge, though he rambles a bit at times jajajaja, in any case I am very grateful that he is out there helping anyone who wants to learn what he knows . With his teachings my diagnostics skills have increased my income and shortened diagnostics time.
Thanks Paul

9 July 2019

Thank you for putting this together Mr. Danner. This is easily the best information I've found on modern auto systems and diagnostics. Its toned down enough to understand and straight to the point. I am re-watching your videos and I pick up new details every time - stuff you probably didn't even realize you were teaching us. Feels good to be back in school again - and I can't believe the value for the money.

I shake my head when I hear you have to tell your students to pay attention when I'd pay good money just to absorb what you have to say for an hour.

Thanks from NH

Mr.Paul I appreciate your program. I am 19 currently enrolling in a Diesel Trade School. 2 Years on hands on experience and will be graduating this December. I finally enroll into your premium channel and bought your book. First thing I learn is omg there is a lot to learn from lol. I have proposed to go section by section and have you as a class with the premium channel. I appreciate your help and you been a great inspiration. I have worked with many guys and the question that I always had is how did you know that was the problem? The mechanical side many awnser me with the correct answer, but on the electrical diagnostic side the 100% answer was idk. I soon realize that many of them were parts changers. The worse decision I considered I can ever make is guessing and not knowing what you actually are working on. I don't want to be a parts changer. That is the reason I always try learning something from your videos I can actually fix the problem correctly. I hate parts changer. Here in Marshall Tx in East Texas that is what it consist of. Im glad we have internet now bc without I wouldn't find you. Thank Mr.Danner ill be enroll in your premium for a good while. You are a true mentor. Sincerely_ Jose Julian Serrano

The book is fantastic, fully loaded and a Blessing to the automobile repair industry, my only issue is that I can only get access to the premium channel video's only when I am either in America or Canada, no access from my home country Nigeria. How can your support guys help?.

5 July 2019

I signed up because I am a Technology Education teacher who teaches in a district that luckily still values teaching Automotive/transportation Technology. I wanted to best prepare my students for whatever training the go forward with after high school. What I have learned has been worth every penny. In addition I do side work custom wiring race cars and street rods. What I did not expect is how much cross over there is and how much it has helped me in this area with so many computer data loggers and more and more digital ignition controls and EFI even in the performance industry. Thank you for sharing your knowledge.

Just finished the book and I was not disappointed! I found you about a month ago on you tube and I'm glad I did. between your you tube videos and the book I feel confident tackling projects I never would have before (like my abs light. Found a bad speed sensor using my Rigol scope! not bad for an electrician).
Thanks for all the hard work. I know you do it for more than "the money". Cheers from cape cod.

Excellent work professor. Thank u. I ran into this 2014 lexus es350 the other day with no A/c operation. This compressor had three separate connectors going to it and to get to these connectors is not easy without saying a whole lot of curse words ??. So I checked for a relay and there's is none. Its internal to the box and I couldn't use my uactivate ??. Now the fun part begins ??. Checked for codes in the HVAC module and a code for "flow sensor" circuit high. Now we are getting somewhere. While In there I checked for other inputs such as evap temp, ambient temp and so on. All looked good except the flow sensor sensor pid which read 3.65 volts. Bi directionally I can command the ac to turn on and off. While doing that I was looking at the flow sensor pid while on and no change. Stayed at 3.65. Alldata didn't have info on this sensor nor a good description or operation. I talked to a buddy and he told me that this sensor is internal to the compressor. Some models u can get away with replacing the sensor but not this one. Computer will not send the signal if it sees anything less than 3.7 volts and i had 3.65 all the time.To the computer it means that some type of flow is going on. All in all with the compressor changed out and looking at the pids again..... the flow sensor pid read 4.5 or 4.8 I dont remember , with the compressor not engaged and with it engaged it dropped to 1 volt. Thought I can share my experience with u even though this little piece of information doesnt even compare not even a little with all u shared and taught all of us. U truly are right professor when u say " just with basic principles and fundamentals u can attack any system". You and ur SD premium really changed my life. God bless

hi Danner ma man, your content is second to none m8, in which I have learnt a lot from so that's great, a little pointer on your website to help you out, the layout isn't the best, you need a layout like you did on you tube i.e how you had actual physical sections for each chapter of your teaching were you could click on and view each individual lesson description and content all in front of you and in order without having to search it on your search bar. the search bar is great if you know what you are looking for but if your trying to go from the start of your lessons to the end it can be quite difficult. hope this helps and once again thank you from a mechanic in Scotland

ScannerDanner's reply:
Thanks for the constructive feedback, I am constantly working behind the scenes to improve the site. If you look at the format of Chapters 2 through 8 you will find them to be organized in a way that I believe has good flow. It is complete with descriptions and related videos etc.
I am also adding descriptions to all of the older videos that were moved over in a group from YouTube (about 250 videos). There are many and this is a timely process but we are getting it done with some help from viewers like you!
Also, I do have a dated playlist, maybe you haven't seen it. It is in the drop-down menu of the ScannerDanner Premium tab, it is a "new videos" list. Every video since Nov of 2017 is in this list (when I first moved over from YouTube).

19 June 2019

. i just watched that video, same exact arcing and sticking problem. i used a different set of leads and no more problems. in that video you were looking for your 5 volt ref and your leads were shorted internally and giving you a bad reading. your check engine light was back on so you tried to crank the car while still connected to one of the 5 volt ref circuits. and the whole time im watching (knowing that your leads were bad ) im thinking man , hes shorting the 5 volt ref , its never gonna start and then you realized your leads were bad and went on to explain exactly that . "that you were pulling that 5 volt ref all the way down. "
And honestly man , 2 years ago i didnt even know a 5 volt reference existed, now , i understand the concepts and the theory and have the fundamentals to see the problems and issues just as fast as you come across them. i thank YOU for that mr. danner, and im sure that there are countless, countless others who feel the same way . thanks for everything man. we really appreciate it!!

I became a recent subscriber and it’s completely worth the cost no matter what direction you chose to take with the invaluable knowledge you will gain from his teaching. If you make a career fixing cars you’ll inevitably earn 2x as much money or you will save hundreds of dollars fixing your own car. Either way, you will win! Thanks so much Paul!

Hi PaUL JUST BOUGHT your ebook is there a way to download as i dont always have internet when in the field im from the uk hope to here from you soon regards Dean Lawson

There is no download or PDF option for my eBook, I understand this doesn't work for everyone, but this format does allow me to offer refunds and exchanges. View the content, make sure it is what you are looking for and if it is, I can apply the cost of the eBook toward the paper book or just simply refund the eBook for you. Thank you!

As a DIYer I love scannerdanner (Paul Danner's) videos and online forum, and I own both versions (hardcopy and digital) of his book, which have paid for themselves MANY times over. Here is just ONE repair I recently completed which saved me FAR more money than the cost of the scannerdanner materials: Some say that for airbag problems you HAVE to have a $5,000+ high-level scan tool. I don't. But I learned on the repair forum that there are inexpensive dongles you can get that plug into the car's ALDL and will interface with an app on a smartphone that will give you quite a bit of airbag code information and PIDs as well as many for other codes you used to need a high-level scan tool for. To fix my son's airbag problem on his 2005 Ford Taurus SEL, I bought a -recommended dongle for about $15.00 and an app for $4.95. I did need help confirming that my understanding of the code data was correct, as well as some guidance on digging into the steering column to fix it. All that help and guidance I got on the web forum graciously provided by Paul Danner and his outstanding mods. I was able to fix the airbag light, saving my son hundreds of dollars over a dealer repair; and the experience of doing the repair was a tremendously personally rewarding. I have ten children and seven vehicles in the driveway. I have lost count of the number of repairs I have been able to complete on these vehicles myself, with the help of scannerdanner's materials, saving me tons of money. Thank you PAUL!

Hello, I have a 98 Ford Taurus 24V DOHC. It cranks but no start. As I am cranking, the RPM gauge does not move. I hooked up my scanner and it told me there was a problem with the cam synchronizer, but I don't see a cam sync on this engine. I see a sensor in front of the timing cover, on the radiator side. Is this the cam sensor? I tried registering, but it didn't allow me after numerous attempts. If you can help me through this page, Id really appreciate it.
Thank You
God Bless

Why are making Pay Pal the only options for paying subscription to your training. Not, everybody, wants to join Pay Pal. What about other options, like your debit card, bank account & etc.

My eBook and paper book can be purchased without a PayPal account.

This is Mike G. from south Texas.
I am a construction worker in the refineries with no diploma or GED, make great money but I love mechanic work and helping people on the side.
I would love to mechanic full time but need to learn as much as I can before I make the jump, so my family will not suffer in my chasing my mechanic dream, knowing I will drop in take home money at first.
This premium channel gives me a chance to take courses that I would never be able to take, at my home and at my own pace. These courses are helping me understand. One day I will get my Diploma or GED so I can get my ASE classes.
This video made total sense for fuel trims.
thank you for what you do, and make it easy to learn.

Guys I have been watching Danner for a few years on YT. I am about to buy his text book. I work as a heavy equipment field tech and as we all know cars and machines are getting more complicated as far as electronics go.

If you're not willing to fully understand electrical diagnosis you will have a hard time in this field. I just can't begin to explain how much danners material has helped me. There is no greater joy than going out to a job that other mechanics have spent lots of time on and still haven't fixed it. Then you show up, and pin point the issue quickly and methodically and have it up and going.

The instant gratification you get from a sewing a customer happy that their machine is fixed is my drive to get better. I'm even shopping for a scope!! That's the next thing I'm going to add to my electrical troubleshooting arsenal.

Danner is a badass tech as well as a top notch teacher.

For the money you can,t beat Paul's teachings. He is a great guy and a great teacher. He will bring you from knowing nothing about diagnosing modern vehicles electrical systems and operational theory to understanding them in no time. You can follow along with his students at Rosedale Technical College for a fraction of the cost. He even brings you along with him on real live cases studies in the field. As a added benefit if your having a problem understanding system/problem on a car you can even seek great advice on his forum. What more can you ask for, at a really affordable price. I've been following Paul for over five years and the information and knowledge I have gained is priceless ! Thank You Paul !

The Book and the website have helped me to open my eyes and think out of the box on everything I diagnose and repair. Every diag tech green or seasoned should have the book.Thank you.
