What a moving story about Rafael Venezuela - I do hope I have spelt it correctly. And how lovely of his daughter to write to you and tell you the difference you made to her father’s life. That’s something you’ll always be able to fall back on, on those occasions when you spill your coffee all over the car, and the new ECU doesn’t fix it, and you wonder why you ever became an auto diagnostician.
It’s a wonderful, moving story, and kind of you to let us all in on it. I think every one of us can relate to it.
Thank you so much, Paul.
😀 my man. You must be a premium member 😊 to be mentioning spilled coffee and a bad call. Thank you so much! Thanks for the encouragement here on YT too
@@ScannerDanner Yes, indeed, Paul; I’m a long-standing Premium member, and proud to be so! The stuff I’ve learned - theory and practice, and the confidence I have gained to apply that knowledge - is worth at least a thousand times the cost of Premium membership. And I’m just a hobbyist!
I studied engineering at university and later took an Open University module in digital and analogue electronics, but it’s only since I became a Premium member that the fundamentals really started to make sense.
@@ScannerDannerWas wondering what shop info systems like all-data pro-demand, Etc you recommendand can they be added to your Autel ultra?
@@toddandamber9769 Autel now has Motor built in with the cost of the yearly subscription. Motor is pretty good, but at times lacks content on some vehicles/manufacturers.
@@LynxStarAuto so always good to have prodemand or alldata as a back up I guess
Lump in my throat here. I can relate, I lost my brother in 21 and while I was hiding from the world I looked forward to these videos and still do. You know how I feel no need to harp on but that's an amazing story.
I'm so sorry Stephen
What a generous human you are Paul. This world needs more people like you. God bless you and the SD community.
I can so relate to what she said , I wish I'd had you as my teacher when I was 16 and struggling through my apprenticeship and like you given stupid books and struggling to understand why I need to know about how hall effects are made but nothing about how to test them on the car etc. You give me something to look forward to when I watch your videos and I love the fact you are such a genuine honest caring person and take time out of your busy life to produce these for us. I thank you sir from the bottom of my heart.
When i started on my own vehicles back in 2013 i hadn't got a clue about OBD2,what's ODD2,oxygen sensor?,Map sensor?,Maf sensor?,trouble codes ?,but, i was willing to learn and i learn't so much from you,i used to watch you in the classroom teaching your students and was fascinated by it all i even became a premium member for a while,oh yeah forgot about fuel trims couldn't get me head around that one for some time but eventually the penny dropped.
The message you read out is so true,you draw people towards you becuase you are a genuine guy 🙏.
The most valuable gift I've been given came from Paul...
I was gifted a voucher, with it I got myself some tool ... Thanks to SD, he's a great teacher and philanthropist
you help people a lot direct and indirectly I can help someone and are helping who could not afford to have a car if I had not gotten help from you to learn diagnostic skills to repair cars, so you help poor people to have freedom and easier life to afford an old car thanks Caleb and Danners brothers for your work
I try to learn something everyday while I watch some of your videos and I do I work on cars all the time
In addition to all the great "how to fix it" info you give us via your videos, you are one of the genuinely good guys here on CZcams! I am honored to know you and count you as a friend, even if it is just virtually! 🙂
Ramdomly watching SD, and suddenly hearing he has Venezuelan friends. A good "Arepa con Queso" to you Sir. Respect.
Caleb’s paying attention! He nailed it when he said that it had to be back near the fuse box since the wires all split from there.
I do not know why i was not getting your site, i missed you i am subscribed. You are the best keep the good work. We need people like you. Thank you!
I'm the same way learning from you is an honor. I've a play list of your videos. Thank you very much.
I always refer to OE wiring diagrams for connector location. I find the redrawn color diagrams tend not to show inline connectors. Good video as always Paul!
Thanks for your generosity and sharing your faith! I'm with you all the way!
Just wanted to share what I wrote to you so everyone can read it.
"Hey Paul, just wanted you to know that I was able to teach my brother who's a parts changer how to test and make sure the sensor has power and ground before replacing the CPM.
This is all due to your and other CZcams creators. Thanks 👍"
Thanks for what you do!
Double thumbs up on this episode Danner, Great human relations content as well as technical content. Makes me feel better in a spiritual way that you’re a man of God… Keep on rockin……
Love your new videos, lots of sirens and horn honking. Sounds like Dallas Tx.
I had the same issue on a 2008 Buick Enclave, I scoped both injector and coil powers. When the injectors dropped out, so did the coils, but only set the injector codes. I found that the screws that held the connectors to the bottom of the fuse box were stripped. I ended up putting cardboard underneath of the connectors then snapped in the fuse box and it cured the issue. That was several months ago. By the way, this is my wife's car.
Bro u have no idea how much u help with teaching what u know. I can’t afford a lot right now so I always resort to u tube in help me learn how to diagnose. Thank u and keep chalices man God Bless
We are here for the knowledge.
I find Its so hard to charge customers for diagnostic's when your not sure of what the problem is, but your sure what the problem isn't. 35 years it the trade has hardened me be tough and you need to believe in yourself, you have made the right decision, and stick to it.
Your faith and honest approach to diagnosing intermittent problems as well as owner unable to give you any history is refreshing.
Recording the mistakes rather than editing them out is another display of your integrity on that PT Loser door switch.
We have all been there multiple times.
Wow so cool that young woman....I'm sure her dad is PROUD.Danner your the man im sure she will be grateful for all the info &help you provide
Got to buy this man's book wish I could have went to Rosedale for my tech training labscope training especially
It is awesome that you did that for that woman you could have been a typical businessman and said sorry about your luck but you have to pay to many of us in or around this field get a bad wrap because of a few bad apples
I hate working for free too, but there have been times that I didn’t; but those rare occasions.
Last time I let someone go the came came in for an intermittent check engine light, P0300.
Ran the basics in 20 minutes.
Unsold brakes
Explained to the customer the situation that the care has great history, everything is new, and gave them a form to fill out next time the check engine light appears.
I further explained that if I continue diag I will charge for my time and the chances of finding something is slim.
Customer returned two days later and I identified the problem. Looking at the worksheet I gave her turned out the boyfriend was using a OBD2 data logger for his job.
Always think outside the box
I did lose diag time but I won a customer for life. She has since brought all her cars to my shop and only trusts my judgment.
Awesome intro!
Thanks for all you do, tenacity, accuracy, honesty and kindness.
I aspire to be as thorough as you, after thirty years in the automotive repair business, every day brings on a new set of challenges, understanding, learning, and of course, humility.
Paul you Erik O Ivan PHD Cuba don't know how much you contribute to us. I a blessed to have a good job in computer I.T. All your guidance allows me to help Veterans and people on fixed incomes. To fix their cars when they can't afford to take it to a mechanic. They pay for the parts only. My time is free. They know I am not as fast the aforementioned group. but also know I will try my best and not be a part changer. Thanks for all you do.
One of the happiest times of my day is getting to learn from you. I enjoy and look forward to each and every video. Thank you for what you do man
Thanks for sharing knowledge and compassion heart . God Bless you and your family
Awesome story... Ive highly appreciated the messages once and awhile, the personal help.
Props to you Paul, for being a caring believer before being a mechanic. You just showed us your true hearts priority.
John 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.
Man SD you really have assist alot of us with your channel. Thanks again
Your a inspiration to many. Not just by teach us great working diagnostic ways. But also life skills and your a good person I follow you on Facebook and your personal account. I'm glad i get to share your journey in life. My son Roman is autistic and we sit together at bed time and love watching your videos. For some reason yoj keep him calm. Maybe you can give my boy Roman a shout on one of your videos that be amazing. Thanks for all your love my brorher.
Make sure you message me on FB about this and I will definitively mention his name in a video!! God bless you my friend
@@ScannerDanner for sure that be so awesome.
Amazing heart touching story😍
I'm sure there are millions of stories like this (including myself), who all benefitted from your CZcams channel free lectures & Premium membership😍
Can't thank you enough SD for all this great work & support❤
Special Thanks to Caleb & James Danner👍
Stay Blessed Danner Family❤
You are more than just a great mechanic and teacher Paul. You are a great human being. God Bless you and your family.
Brother paul.you dont even know how you inspired people by you honest legit work.i am on other side of world learning from you sma and phad oz alad and other guys work as they always mention you in their videos.its a blessing for you to be a inspiration for so many.cheers stay blessed
Thank you so much!
Happy Sunday and thanks for teaching Scanner Danner and son Caleb , God bless you and your family for all your time and teaching us ✋✌️✌️✌️✌️✌️
I love your youtube teaching
Hmm, weak battery/charging system could be contributing to this problem. Thanks for the moving intro.
I love these stories; keep up the great work.
Technicians/Teachers like you made me stay in this field, after graduating high school everyone told me do not get into automotive field because of how mechanics are and its cut throat field no one is going to teach you. But people like you proved them wrong. Thanks Paul. By the way that link you referred to (3:43) I do not see it. :)
Oh shoot, I forgot to like it! Looking now
Link to video mentioned with a bad O2 sensor causing misfires on one bank czcams.com/video/H6lY42u19VM/video.html
Thanks a lot danner you are the best man I learnt a lot from you and still learning ,big thank you from algeria 🇩🇿
Huge fan been watching for years. I have worked on those vans before and I have seen the injector harness rub threw and ground on the block in the rear of the engine (unfortunately under the dog house)
I always get a few good laughs when watching your videos. 😂
I'm glad! Let's have fun while we fix some cars right?
i started watching scanner danner when i was homeless too thank you
I don't know about a 2015, but older ones of those vans had a problem with the engine harness rubbing through on the left front upper control arm mounting bracket.
I learned from you so much brother ....god bliss you.
can't lose with an attitude of gratitude !
👍 much respect and appreciation Paul!
Great job team Danner 👌☺🔧
You are a Blessing.! Thank you for Preaching Jusus in your life and what you love to do.
I appreciate that my friend
May he rest in peace Cathy 🙏🕊,may God bless you,your dad and your family, 🙌 🙏 ❤ take care mam,wish you all the best..
Great video
good info. thank you for this video.
you got my eyes leaking at the start you done very nice thing for long time subscriber s daughter big thumbs up mr paul danner well done calebs question reminds me of someone have said right if you change a part and the fault is not fixed what part would look at next check that part before replacing any parts
Second part? I can't wait for it.
Great job man 👨
Genuine.... God Bless, and thank you for the videos sir.
I remember that name in the comments section for sure! I think he may have even been a premium member from your initial service through CZcams in the early days.
Having this same issue on my express.. random misfire but only when going above 40 mph. I don't really feel any misfire, CEL just flashes if I start to decelerate. Can't wait until your next vid!
Yes sir Thank You Paul for everything your knowledge is much appreciated. As a man, father thanks brother 💯
Well said. I agree 💯 percent. Intermittent problems can be a real pain.
Leaving us with a cliffhanger 😬
Great comments from the heart 👍🙏
As soon you took that fuse out the fuse box and put it back in all those codes are coming back that had my mind thinking as a fuse box or wiring problem we have alot of these work vans where I work at and that's why we see a fuse box laying around inside their good work vans
Having the same issue with a 2016 4500 Express School Bus, replaced the fuse box and problem was fixed, thanks for the info. I must add our local Chevrolet dealer had it in stock .
Awesome, thanks!
I work at a GM dealership and had one of these with the same exact codes on bank one and it was a constant dead misfire on 1,3,5,7 connected a head light bulb to the power feed and it would light it nice and bright. Fuse box fixed it though
I fix one a few years ago was the fuse box
you are a good men and a good tecq,,,
I wanted to advise you to look along the wires to the injectors as, if one of them shorts to ground, all will lose power and the code will appear. The fuse will also blow or the pins will become loose if the short is very short (in time) and the fuse doesn't have time to blow but the pins get melted a bit.
Now that I've seen the end of the video I understand there must be something else.
Nice video anyway. I waited for one like this for a long time already.
Cheers!
Danner's having eye trouble. Cant see himself working on the Express🤣🤣🤣🤣
Hey paul I have worked on dozens of those gm vans and had that exact problem around a dozen times and every time I monitored the power feed to the injectors and as it gets hot I would lose voltage . The cause was a bad solder joint in fuse box . I dismantled one box and I could see a lose pin on board where the solder was not holding and failed When hot . Hope it helps
I agree!!!!
Thanx bro!
I am in tiers.... God bless you 🙏
I noticed both times you had voltage spikes you was turning the wheel left, maybe a wiring harness near the steering shaft or in the ignition wiring to the key and tumbler? Just a thought buddy
God bless u and your family big boss
Well at least you got a chance to see what’s causing the problem. I think it’s too much of a coincidence that scope reacted to the gear shifter. I think your getting close Paul
Well spoken,,, reality.
Those intermittents definitely do SUCK!!!! Had an 07-ish I think f150 customer had to bring back 4or 5 time for no crank. Dash, abs, and pcm we're all on the same COM lines. Finally acted up long enough, found the pcm dropping out of the com circuit. The the Cust didn't want to believe us and wanted a second opinion from somewhere else. Have fun son !
So funny I had a 2016 Express with similar issues in the shop, I wonder if my fix was the same as yours....;)
Your comment about charging is a tough one. I have given away a fair amount of time and money due to the fact that I couldn’t find the root cause of an issue.
I had this issue come up on a 5.3 suburban 2008 . Had a bad ground wire on the back of the head
that was nice .
Like videos man 👨
wow a fun one you should have been checking battery vltage at the same time. especially with the alternator singin like that.
Great video as normal you also need a ground. Although supply cables joints good how's the return neutral. Your pickup is common and your not using the earth the injectors are using. I've had a loose bolt chassis bolt worked ok till drove rough roads vibrates loose. Was hard to find hope find in part 2.
AMEN Paul!
just like the first garage. said i needed a cat. and boom same problem, only now it has that code because they didn't use OEM.
Hope you are doing well brother 😁
I was born in Hemet CA! Phill's Probe!
From the beginning when you were getting low voltage I was thinking... "voltage regulator " in the alternator.
When you don't have much direction to work with on such an intermittent problem, you'd might as well pull and plug all the fuses and relays a few times to eliminate that as the problem. Check any easily accessible pertinent connectors and grounds too. Don't cloud your mind with too much doubt about everything. If the problem persists, you can then start a proper diagnosis with a clearer head. It's not always useful to spend stupid time and money to prove that the problem was just a poor connection at the pin of a relay.
This is the 2nd misfire vid on YT. It was a Fuse Slot fix.
To God be the glory. May our God continue to bless you so that you may be a blessing. Keep your eyes on Jesus brother.
Hey Bo! Hope all is well for you my brother and thank you!
Been there with this one, power distribution schematic will show the trans range sensor in the curcuit as well then you will question Mitchell's competency
So I had a case earlyer this with the same kinda van. I ran the same test then removed the fuze box and opened it and it was burned inside the fuze box same fault code but mine was not intermittent so sold a fuze box then found the tsbs on this problem
I agree with the logic that it's not likely to have the same problem across all 4 separate wires, so it must be upstream from there-- which would be the fuse box/ fuse.
Looks like at the end you need to apply parking brake while in gear in the low voltage condition.
Caleb thank you got the eyes for 🎥
Take care and have a great day Caleb
Great Questions Caleb loved it
Prodigy Sir ScannerDanner
Can't wait for part 2
Thanks for sharing what you know with us great tutorial 👍 God bless you and all your family around you Sir ScannerDanner
