Hello Paul, I'm a 59 Yr old fart who was an hgv tech ( semi truck to you & your US bros) for 30 years. Turned my hand to everything but electrics. Seems to me, I was born with an open ground in my head with a 12v sensor feed to the dark place where electrical understanding is stored. The bulb just never lit. I have been watchin & lovin your vidz for a while now and thanx to you the grounds are being fixed one by one and the reference signal voltage is slowly coming down. You're an absolute fkin genius with a mind like an ECM. I'm blown away by and still trying to comprehend just how much stuff is inside your head. Just nipped in to pass on to you a humungous thank you and major gratitudes for sharing that most valuable asset a human being can have is knowledge. You're amazing man‼️ You keep makin em we'll keep watchin em. Happy & healthy life to you & your family.

Alec Nemeth - I'm on my 50's, thankfully for me, my long time deceased father in law. Started me on the "dark magic" of the electrical side of vehicles. He himself started as a 12 old apprentice kid building batteries. Different times for sure. By then I already had a quite decent mechanical background. That simply add the cherry on top of the cake. ;-) One of the details I never forgot was, in general, to keep contacts clean, grounds in particular immaculate. I can't state enough how much it kept me clear of "car troubles" over the years. Since one way or another I'm always messing up with "mechanical stuff". Keep that on top of my to do list. Worth every penny. Except for family or friends who seem to take advantage of it. LOL 😂 I also thank ScannerDanner for his knowledge sharing. Big Thumbs up. Cheers all

Hey thanks brother! It is good to hear from you. You've built a great channel yourself!

[@spelunkerd]

My first instinct was a wire-to-wire short to battery power, so it was a surprise to see this was caused by a poor computer ground. As you say, if the computer ground is bad, the computer voltage regulator that produces the 5V standard will have no reference baseline to produce exactly 5V. It was really helpful to hear your remark that every time you've seen it, the problem is not a short to power, it's a bad ground. That's where experience trumps book knowledge, invaluable. Thanks!

Thank you for this video, I am just converting a loom at the minute and was failing to understand why there was a normal set of grounds and sensor grounds. This video has cleared up the wiring diagram perfectly and I can only thank you for that

[@glenwhatley4125]

Again, beautiful to show how a logical approach makes sense and works. I know you wouldn't normally be working on am electrical system with power applied. Only thought is mention that whenyou have grounds from different systems connected together like that but not connected to ground, they will seek a lower resistance (via current flow) through the other floating grounds. That could potentially damage the more fragile circuits e.g. say a headlight seeking ground through the computer lifted ground wire. Of course the headlights aren't on I'm just using that as an example. It may have been one of those mercy repairs for a friend but look at the great opportunity it provided for a great example of trouble shooting. Thanx for you videos!

Thank you friend. I had an auto electric class with almost no hands on and zero mentoring, a lot of it was a waste of time and not applicable to repair work. Reviewed the book we used, it said to dc the sensor to check the gnd wire for voltage drop; of course this made no sense to me as no current is flowing, and this brought me to your video. You have a great talent for auto instructional videos. There are great mechanics but many lack the aptitude for teaching in a coherent easily understood manner. Well done.

I kinda knew the 5v had to be present at all sensors (Like washing machines!) So finding it at almost battery voltage... had to be a "grounding" problem somewhere. BUT.... That was a mega hint on the Fords: No Check Engine light..... Thanks for that. Big saludos....And thank you.

[@ray32825]

Hi, I used to love using the Vantage around 15 years ago when I was an auto/electrical tech. Loved the tool, it was well made (in the US :) ) and at one point I actually thought of making it rechargeable since it was quite power hungry. I did use the pro version a couple of times, but did not like it as much as the original. BION but I had a couple of these, in the cases with all the accessories, and sold them on Ebay thinking I may never need them again. Recently I had a problem (p0325) with an 2003 Honda Element of mine an wanted to see the waveform of the knock sensor - I still work on cars now and then. Obviously you still love using the good old MT2400, but what would you suggest I look into getting to be able to view a wave form? I still use a power probe and was wondering if you had used the new Power Probe PPTM01AS (Maestro), or shall I go for a scope like the Pico, Hanteks, Signstek DSO203 or a multimeter/scope like a Liumy? PS I don't mind using a laptop/tabet - I have a bunch of Toughbooks. Have a great New Year. :)

[@ScannerDanner]

It is no different than any other circuit with a bad ground. No current flow = no voltage drop. The ECM board itself has no ground, so all power coming in and circuits trying to operate cause the entire board ground voltage to rise. Hope that makes sense. I could draw it better than describe it. I'm sure I do in one of my playlists I provided here in this description. The ground circuit problems one. There's like 6 videos in that playlist.

[@user-so7dj3tw4d]

Defend those who are not present? I don't know about that but it is good to assume the best of people. However if money exchanged hands for a job not properly completed and later more issues maybe major issues arise is just plain bad. I usually say I'll see what I can do for you and try not to mention anyone else because for all I know it could've been the customer who was screwing around trying to fix something. If they have receipts then it's fair play only because I don't want my people to be screwed by a shoty mechanic who accomplished nothing but took money for a job well done. People need to know sometimes mechanic really are out to screw you I've seen it myself firsthand. My cousin lost his Honda accord because a mechanic wanted his payment for the car which he never fixed and the mechanic ended up keeping the accord in the end. He never even moved the car from where we left it on the far end of the lot. This is what got me to want to learn so I could help my family and friends stay on the road safely while not getting screwed by Chris (the mechanic) and losing their transportation. I definitely had plenty to say about that mechanic lol.. I tell everyone he is no good. In the end the court gave him the car due to taking space in his shop even if he hadn't touched it.... that rat bastard!

[@DavidBrown-tl5yh]

Great one Paul. A VERY good lesson in getting initial direction by checking the basics and establishing certain "MUST HAVE's" then going from there. You must have a focused approach to be effective in any diagnosis and repair. I think you presented the point well in that if you don't have a 5 volt reference, (that is supplied by the computer) then you do not have what is needed to make the engine run. It is as basic as trying to start an engine without any fuel.... it will not work. The lack of ground to the computer means that the entire computer was "FLOODED" with 12 volts with no way of working and providing anything else than that battery voltage to ANY circuit. The 5 Volt Regulator Circuit needs a ground to function. I am surprised that the engine ran as well as it seemed to after all that had been done to it. You made a valid point.... diplomatically.... 'I hesitate to take this one on'...... 'freebe'..... but let's see what is missing. Also the point about remembering a similar case from 20 years ago is very valid..... maybe not exactly the same, (although in this case it was), but valid experience just the same and usable in this similar situation. A good combination of UNDERSTANDING, EXPERIENCE, DIRECTION, and MEMORY is unbeatable in so many fields..... LEARN FROM THOSE THAT HAVE IT! Sometimes these ones will also have a good story to relate with the experience that will help you remember the point.... listen to them and remember the lesson. Thanks Paul for your lessons and experiences.

[@ScannerDanner]

very well summed up my friend, on point exactly! and we need to not be afraid to bill for these types of job. If I'm a garage owner, this is a $150-$180 repair all day long and the customer is happy to pay it. Our knowledge and expertise should not be given away.

Thanks again mate. Just subscribed. Forgot to mention your the first you tube video I have commented on for a Looong Time.

[@ScannerDanner]

Thanks so much!

A great day when i see a scanner danner video. Btw another thumbs down..good greif..who's the troll..😲😲😲

[@ScannerDanner]

Got in influx of new ones from FaceBook lol

[@InsideOfMyOwnMind]

@@ScannerDanner Immigrants! Now that I've addressed the boneheaded side of the equation let me just say I hope these kids know how lucky they are to have you as their teacher. BTW my 88 Impulse uses the TPS switch. It only senses idle and WOT. Funny thing about it is normal operation is no pump prime before cranking and OBD1 DTC 12 is normally always stored to indicate that RPMs have been too low at some point during the current key on condition...Duh!

@@ScannerDanner awesome video thank you sir!! I seen this go the other way where a cam sensor on my jeep was reading 1.6v on the signal wire..after verifying I had my full 5 volts supply.. I've learned so much from you..keep em coming

Where is cale the singing camera man?

[@ScannerDanner]

At school

[@ChuckWD33158]

That was helpful. I had a 2002 Dodge 1500 with a no start, checked the ref signal at cam and crank sensor, none. Checked continuity to computer, it was good. Replaced the computer, and all was well. Keep the vids coming.

I just started watching your content and will be purchasing your ebook. I think you're an amazing instructor and would have really enjoyed your classes as a student. I can tell you have an amazing ability and your students feed off it to the fullest! Thank you for teaching and being an inspiration to our youngsters!!

[@ScannerDanner]

Wow this is a humbling comment. Thank you so much.

70 Dollars an hour to work on your car , 150 Dollar an hour , if You worked on it First

This was many years ago but the sign read, hourly, 30, 40 if you watch, 50 if you help.

This is why you’re the best Paul. I’ve been recommending your book to guys at work. Thanks for the video!

[@ScannerDanner]

thanks so much!

[@sparkyobrian6417]

time to walk away, it would be cheaper to scrap n replace labor is labor.

[@ScannerDanner]

Or just watch and learn something. It was a no cost fix. Edit## read below, this was a misunderstanding on my part.

@@ScannerDannerto My 2009 Buell Ulysses and many other Buell with aluminum frame have computer ground issues caused by unseen with the naked eye resistance caused by dissimilar metal of the computer grounds and that dam aluminum frame . I was getting a DTC light lean O2 only at 70mph + . Light would go out when slowing down below 70mph . Cleaning aluminum ground points where computer grounds we're located was the solution. still will have issue sometime in the future and will have to repeat cleaning of aluminum because of dissimilar metal affect. Bad design

[@ScannerDanner]

@sparky obrian Sorry man, I misunderstood you. Forgive me. I've just been dealing with trolls all day on Facebook Your comment was valid in that regard. I took it as you saying I was wasting my time showing this fault.

[@sparkyobrian6417]

@@ScannerDanner my apologies also, im too quick tempered- the biggest character fault of all, believe me. I wasnt clear either, Im constantly trying to make a trouble shooting job fast and accurate and not loose money, its hard in my field, hence its important to know when to pass on a job.

[@ScannerDanner]

Thanks brother. It's hard to gauge intent through text on a screen sometimes.

[@ASEWorldClassTech]

honestly I am now a follower. I purchased a Vantage Ultra today, gotta deal on it at $1200. I have all but A2 and L1 on my ASE's and just looking to get even better. Subscribed...

awesome! thank you

[@davidburman451]

Thanks...excellent video. Retired senior my job now is keeping our 2 older vehicles purring without going out and buying new like most my friends have. Cars have always been a passion my entire life. My career however was in photography and I feel your pain about hard sunlight. Back in the day shooting weddings we loved hazy yet still bright days. Hard sunlight made it very difficult indeed. Many a brides mom took offense to us posing them in the shade......but always were thrill when they saw the final results.

[@ScannerDanner]

We've stepped up our game into 4k, my latest 2 part series shows it and my son Caleb is my cameraman is is researching all of that stuff now. Thanks for the comment!

[@domingoahumada9637]

Wow! You just made my weekend! Can't wait til Monday at work to check what I have been working on. you just made this whole 12v. to 5v. Bad ground. So easily understandable. I'll definitely be checking your webpage Thanks and keep up the good work.

[@Albatr0ss222]

Looks like Michigan there. Great video. I've been a Mobile Mechanic here in Ann Arbor for the last 15 years and a Mechanic for 30 now and one things certain I am always learning something new!! I love being a mechanic and really enjoy jobs like this, like you said, once solved they pay in spades. I use parts buckets for my tools and fasteners to stay organized (busing tubs or dish tubs) it helps on jobs outside of the shop. I miss my quick strippers (we used to use HEI advance springs to fine tune them when I worked at Roush, ha). Anyways I'll pick up your book and I'm sure I'll learn from it!!

[@antonioglcarvalho4117]

EXCELLENT DIAGNOSIS HE KNOWS WHAT IS TALKING ABOUT .

[@galorivadeneyra]

Thanks so much!

[@simonwebb2675]

Thanks for another great one Sensei Danner, we have some well known names here in the UK but are not close to you in any way, you have a unique speed and precision about what you do and how you explain it, i only wish you were in the UK to be able to train me. Until then though i'll keep watching your videos. Love your book by the way, still not even 20% of the way through but it's to the point and not crammed with smalltalk.

[@ScannerDanner]

Thank you so much my friend!

[@john7017]

Great Video! Thanks for sharing. You are the master at explaining system operations.
