Customer states "You are the customer"
Man I love your content I wish there were more people like you when I was growing up! Education and entertaining. This is the kind of channel I admire the work that goes into!
When a Me-chanic has to wrench on his own rig....... Mechanicing!
i recon what you did is finger tighten the bolt and didnt nip it up 👍
It takes a good man to make a video to point out his own mistakes, it takes a bigger man to own up to them . Still a good trouble shooting diagnostic video with good content any way you slice it.
Your time is your own time, you don't get paid for fixing it .., the upside.., you didn't have to pay to get it fixed.
*hits the like button.*
So…. You are a regular customer,(not a real technician) , and you bring your vehicle to a dealership. They fire the parts cannon because they claim the data told them the modules lost connection. Thousands of dollars later, your vehicle still doesn’t run. The service writer apologizes for not fixing the problem and recommends you speak to sales and purchase a new vehicle. This hypothetical situation is becoming the reality to most vehicle owners. Wish there were more experienced technicians with ethics, like you Ray.
Totally thinking that (Sorry A-Rod). Can't imagine some mechanic testing things one by one and simply RTFM and finding the issue.
There is a video about that exactly scenario on Banks auto, another shop told to the costumer she need to buy a full new cluster and new dashboard components, when banks look in to it was a mouse eaten a cable!!
I had a new beetle in which groundhogs ate my "eco-friendly" cable sheathing and hoses. My mech patched everything up with stuff he had lying around for 80 bucks. I cried when he retired. Fortunately, I found another mechanic but he is also overworked and near retirement...dammit...the good ones are always snowed under a workload and a half and tend to retire. Small town where I used to live, the "awesome car dude" was working on cars into his 80s...so people were willing to give him time to "get around to it". He loved meching like Ray does...took his time but he was so awesome and it was small town life and speed so, nobody cared...LOL
Greetings: Ford is typical of that. Others not far behind. I find it is less expensive 2 refurb and upgrade der stuff and end up with better It has proven itself with time. Thx 4 the share. Bsafe.
That's the quality of techs they get on the cheap because they hire them straight out of tech school. They know how to use tools, but don't have any experience diagnosing issues.
So, the problem literally was......The nut behind the wheel and in front of it. Our favorite mechanic and his Mr. Ray.
The LOOSE nut behind the wheel...

Geez, All that hassle for a loose/missing nut... I can't imagine the look on Ray's face when he realized it was just a faulty ground that he had removed during his dash upgrade. But at least he didn't have to take the whole dash apart to fix it. Kudos to him to finally figure it all out.

Having followed your channel since just about the beginning - dealership days- I am constantly impressed by your willingness to share even those experiences which others might not want to admit to. This is a sign of great character and the ability to grow. Hat's off to you, Sir. Back when I was in the electronics repair business, we would call this a TIF (Technician Induced Failure)... not that it ever happened. lol. Cheers guys. Great video, thanks for sharing!

Bad grounds can make you chase your ass a round all day. Glad you found it
Luckily these days the information is available online, where you can see the diagram and search for the location of the things you need in those situations. Back in my day...........
@@AstroBoyAU LMAO..... The 'Back in my day' line brought back some painful memories. At least we had a telephone. It was good to know the old guy with a photographic memory too!
Ray had his own comeback. Thanks for showing us you are human.
How many times has he "forgot" something on a customer's car but didn't do this extensive of a search for the problem?

@@user-ho5xe2nu8o why do you say that? He is human, right? Why is is so hard to imagine that a human messed up?
As soon as you plugged the scanner in and everything came on line I knew it was a ground problem. Glad it was an easy find. Have a great day buddy!
Beat me to it. Grounding through the scan tool.
Hehe.said it was a ground problem in the towing home video.
He said he hit a puddle and everything went crazy
I thought it would be a network open and the SCAN tool was bridging it, which it was, it was just bridging a ground not a data line. Kinda like where it looked Ray was going. But before he showed the scan tool made it work, my first thought was.. You had the whole dash out not long ago, probably a bad connection behind there.
Makes you wonder how many customer cars he didnt put back together correctly.
Even “Ray the Magnificent” can make an error. I’ve done the same thing. You still ROCK.
So your truck downloaded the Crowdstrike update!😂
Crowdstrike---- when the Windows fell
More like the OnStrike update...
🤣🤣🤣🤣🤣🤣🤣🤣🤣
Crowdstrike will never live that down. have to say it sucked though as it hit all operating systems if you updated it lol
Electrical gremlins can be a PITA to diagnose but are SOOOO satisfying when you get them fixed!!!
I had a customer in 2011 bring in a Ford chassis cab bus to the shop. It would randomly loose all throttle, would run extremely rough, and sometimes stall. Typically a restart would get it back up and running, but for an indefinite period of time. He had already spent $5k at 2 other shops trying to fix this issue. We were his last hope.
The data scanner showed that the TPS would suddenly show zero throttle even when the ECM commanded throttle. All wires were in good shape and ohmed out good.
After a couple of weeks of wracking our brains, we finally figured out what was going on. Ford engineers, in their infinite wisdom, changed the TPS sensor on the throttle body from a potentiometer type to a magnetic read type. Well, on the 5.4 and 6.8 motors, the alternator is RIGHT next to the TPS sensor on the throttle body. Those chassis buses also all utilize an aftermarket alternator to deal with the extra load from all of the lights and dual AC systems. Those alternators were around 250+ amps.
With the new TPS in place, as soon as the alternator started putting out a lot of power, it turned into a giant electromagnet, which would scramble the TPS signal!!!
So, our fix was to replace the new TPS sensor out to the old one. Problem solved!!! So, we went around to all of the local Ford dealerships and bought them all out of their old TPS sensor since we worked primarily on chassis cab buses.
"The person who never made a mistake never made anything" served me well for over 48 years as an aircraft engineer. Still makes one feel stupid though. Well done on the troubleshooting, had a few difficult ones in the past myself. Retired now but still miss the challenges.
So it wasn't the Banks stuff, it was the guy who installed the Banks stuff! Good for him he has a great mechanic!
It was Ray who changed whole dashboard when he modified interior, he forgot that ground connetor. Everything was out of cabin when he did that interior update.
🤦🤦
Hahaha oopsie.
It's not related to Banks stuff in a slightest. Did you even watched the video?
@@SmallKittyPaw I see that reading comprehension isn't your forte
I know the pain you feel when you just can't figure out a problem, and you search forever, and think you'll never find what you're looking for. I also know the pleasure from your laugh after getting it connected, when you find a very simple problem, that was even all your fault, but you're grateful that you can actually fix it!
There is great satisfaction when you find an electrical issue and you know you have the root cause!!
I had a ground issue on my plane that took me 7 hours to fully track down and fix!
On an Airplane an Electrical Ground can Take You Down to Real Ground Potential--not Good...
Meanwhile the rest of the world would buy a Wal-Mart code scanner, plug it in and tuck it up behind the dash... (ducking to dodge flying tools and chairs) I am eating this video up, this is the stuff that makes you bang your head against the wall and Ray is just cool and calm going through all the steps.
Single piece of wire to bridge the two grounds at the obd port and some hot glue to keep it in place.
"Good as new"
This was/is a great video! Phenomenal diagnosis and repair. It's almost always the simple things. Reminds me of a proverb (I paraphrased to make it fit this scenario):
For want of a nut the ground was lost;
For want of the ground the circuit was lost;
For want of a circuit the power was lost;
For the failure of the power the Silverado was lost-
All for the want of a 10mm nut.
As soon as he said 10mm, 😂 😂😂
Baffling real world mistakes like that happen to most of us who have ever tinkered with vehicle electrics, and would often take days to fix reliably. Your faith in a proper diagnostic process got to it logically and quicker than I'd have thought. So well done Ray!
Corndogs on the house!😊
Spot on. I recently had ECT sensor 1 and O2 sensor DTCs after a muffler installation...forgot I also deleted the symposer and never plugged the ECT back in. I was too focused on the O2 sensor. Fail!
Reading those ladder diagrams as well as he does really helps.
Heck, just having those diagrams really helps.
While working at chevy dealer in body shop ,heavy collision had almost same problem because the same ground wasnt tightened by me when i had to install new dash but it was intermiten problem.9 hours later found problem almost lost my mind again while customer yelled and bitched,My thoughts go out to you because most dont know how much stress this problem causes .Great diag GO RAY GO
Get GROUNDED Ray!
Sweet that she is ALIVE.
great new T-shirt logo...?
@@lomni02 You made a GREAT point :)
Thanks for again showing us the value of sound diagnostic process. All the codes in the world will not find a ground issue.
Moral of the story. Mind your nuts!
Ray, I love the fact that you share your “Learning Experiences” with us. 😊
I have a suspected ground issue that's causing all sorts of dramas on my 27 year old land rover that I can't seem to pinpoint. It is amazing how such a simple issue can cause so much of a headache. I'm happy that you managed to find and fix the issue on your truck. I love your videos and have learnt so much from them.
To quote Scottie on Star Trek, "The more they overthink to plumbing, the easier it is to stop up the drain."
The more complex electronic systems get, the more vulnerable they are to simple faults.
Glad you found the problem, at least you know who to punish for the oversight.
That is a true remark. We need more simple things in life, not this electronic shit in every bit there is. Bling-bling is for girlies, men need raw and robust!
Gotta love the terrible redundancy built into the electrical system that a single ground can take down the entire network. That's quality engineering there!
Exactly. Most engineers are lazy. When ever I think of automotive engineers I also think of Pantera's "Five Minutes Alone".
@@Viracocha785 "AS CHEAP AS POSSIBLE" forget that a single ground took out the entire network. What if his vehicle stalled while making a left-turn against traffic and a truck couldn't stop and hit the guy. Like would a dedicated ground wire in the harness instead of relying on a chassis ground alone, be too much to ask? But that one olive they don't put in a million jars is a lot of money saved is their attitude.
I am a retired Electronics Engineer. I agree that a single ground node missing that can trash an entire communication system is darn foolish.
Sometimes chassis ground-loops can become difficult to engineer around. I expect it was one of those. The biggest problem with CAN bus is that while it is a differential 2-wire system, it also has a specific relationship to vehicle chassis in terms of levels and common-mode limits. This is never good. Ethernet avoids all these issues by isolating the communication cable from all transmitter, receiver and transceiver modules connected. So it is unlikely that a power-ground terminating one or more slave nodes can take down such a network.
If the CAN standard had begun with opto-isolated or transformer communication coupling at all nodes this problem would never have occurred. It would just be "module/s XYZ offline" instead.
Well folks here is the best news...
Tesla used their Cyber-truck design to implement several long-needed advances to vehicle electrical systems.
* 48V low tension instead of 12V.
* High-speed Ethernet-like G'bit communication bus with proper common mode and differential mode isolation on all modules.
* Diagnostic potential from the main screen is still immature but I would expect this to become highly sophisticated in the near term.
OBDII is basically a good standard tool but when all vehicles have a fancy screen, such tools will likely become largely redundant.
It would be foolish for other vehicle OEM's to not follow this lead - irrespective of the power-plant and/or energy source - going forward.
@@jimparr01Utube I think it's because they grew from analogue and chasis ground into high-speed and low-speed (and sometimes medium speed) networks piggy backing on a more analogue system. But still, having a ground wire in the connector versus chasis ground would have been better if they couldn't do both for some of the reasons you described.
@@CedroCron To be fair, I was always taught that you should predict your car will die at the worst time. Plan that you're not going to make it through the intersection and leave the oncoming guy enough time to stop if you don't.
Oh wow. So I had a 2011 tahoe. Had a couple gremlins. Turned out that the ground up in the dash had sealant from the windshield install in the connection. 🤦🏻♂️ You brought back the horrible memory of finding that.
Brilliant detective work again Ray! I invested in an OBD2 breakout box which makes testing pins a breeze. I'm well past the point in my life where putting my head under a dashboard works. Glad that you're back in your trusty steed!
When you plugged in the scanner and it was alive, I immediately said: "Bad Ground". The scanner ties the two grounds together when plugged in. Seen that a few times myself.
Wow! What terrible luck to have one of the worst possible connections to overlook. Glad you found it quickly Ray. Good job!
You could have worded this so it didn't spoil the video for everyone who sees it and clicks away bc the mystery is ruined
@@yeahitskimmeldon't read the comments till you watch the vidya
I had a 2005 silverado that did almost everything yours did, but it was still drivable. After several hours of messing with it, I unplugged the aftermarket steering wheel control interface harness that I had for my aftermarket radio. As soon as I unplugged it, everything returned to normal. Ended up replacing the harness with a different brand, no issues afterwards
1:07 when I first moved to Tampa FL years ago, my dash looked just like that. Except mine did because I parked my car to go to work one day, when I came back at 4pm, someone had helped themselves to my stereo equipment and everything else inside my car....
We all saw the mess it was when you re-did the interior so it's no wonder how you missed that ground. That's gonna make you wonder if their could be anything else you might have missed. I guess if their was anything else it will pop up sooner or later. 😁😁 you're still a grade A tech 😁😁👍👍 That was good troubleshooting skills though. 👍👍👍👍
I don't know why but the Jurassic Park Door Locks clip kills me every time 🤣
same here and it makes me want to watch it again
Just watched the movie yesterday , now I get it😂
29:04
Must be something deep down wthin you, from prehistoric times.
I love those clips
Electrical issues has never been my forte. Watching your channel has helped me understand more, especially in the modern high tech vehicles. Modules, talking, network, etc., I can follow, but seeing your diag of this issue with your Silveryrado was fun. Glad that you found the ground problem. Not surprising that with all you did modifying it during your mods that a ground escaped being connected. Sorta glad you were able to find it was "just" that and not some other weird problem. When I saw your dash apart in the parking lot I was scratching my head, and there's not much hair left up there nowadays. Thanks for taking us along on this. Amazing what a loss of ground did. 😊
Rainman Ray.. I was thinking you probably missed a ground or didn't get one quite tight enough when you had the dash out. Glad it was a simple no money & no parts needed repair.
Ray, when you took out the Dash a year ago, you didn't reconnect that ground wire. I'm glad you were able to diagnose and fix it. I like that truck. And like me I need my truck too.
That's awesome it was just something simple, crazy how we can do all that high end swapping and upgrading and miss one little ground wire that throws it all into total chaos. Great find!!
Great Find! I too have created my own problems while working on stuff. Sometimes you have to slow down to go fast and trouble free.
I really enjoy your Movie Clips when addressing some issues. It adds humor to an otherwise frustrating situation. Keep up the good work, we really enjoy it.
1 part required ! A 10 mm nut ! How that ran so long since the dash removal is pretty wild !
Labor 6 hours diagnostic, parts 10 cents, installation of part .25 hours.
Ray, I knew you'd find the problem and thank you for being transparent with your viewers!
It's going to be something easy because there was a rain bow when you brought it in
You've always harped on the ground and how rusty cars and connections can cause problems great video and showing how something so small can be huge. Love your honesty and channel ❤
From watching a lot of Pine Hollow and Eric O my first thought was bad ground.
A friend of mine had something similar like this happen to him. His "computer" died in his 2000 Dodge Ram van 1500. Essentially, he had to get a new one and get everything reprogrammed. It wasn't cheap.
Oh remember the good ole days when you could just work on cars without accessing Skynet by Cyberdyne systems for Sac-norad!!!! 🤣😂
I got to say that I appreciate your honesty and integrity, as well as your wit and brain surgeon like attack on all mechanical and electrical issues. You are at the apex of your craft. Thanks also to your lovely wife unit.
Cool video and excellent deductive reasoning on your data line loss issue. Always amazing what a simple ground circuit issue can cause.
GM is famous for the U codes. That usually means that the main harness has green crusty, according to South Main Auto’s Eric O.
You should take the kid and make him do nothing else except look for the danger zone in everything he interacts with in the shop for an entire day.
He seems o be on cruise control simply cause he's young and doesn't know yet.
Not criticism,your a great teacher.
When all of that stuff was torn apart.... I thought... I guess now is when most customers give up and just drag it to Eric at SMA lmao. It always amazes me the amount of cars he gets that look like that lol. I could hear his into.... "Today we have an 07 Silverado, and you can smell the frustration!"
This stuff (diag electrical issues) is Scanner Danner bread and butter. From watching his videos I suspected a bad ground for two reasons, circuit high codes, and when you plugged in the scanner that provided a ground through your scanner on the data link connector. Got that at 5 min in, and my first look would be at any after market connections made, something may have been missed. ❤ your videos, good job Ray
Been waiting for this vid. As soon as you plugged in the scanner my first thought was that it was a grounding issue. I had one on my Durango and I was literally chasing my own tail in circles for what felt like forever. Great job finding it and I love that when you make a mistake you still show us the mistakes instead of making them disappear or making excuses. Keep it up
Your car is requesting a scan tool for itself. 😁
Sorry not part of the default kit, must issue a MAC to add new equipment.
When I watched part 1 …..
Rot-Roh …… wiring ……oh the humanity ……
So many things fubarred !!!!
Great work on locating the issue !!!
Oh yeah…. Now I remember……
It was getting late…… I wanted to get this dash IN !!!
Overlooked one lil wire …… out of the multitude …..
Glad it was a relatively minor issue !!!!
0:24 “double rainbow all the way!!! What’s it mean?”
Really thorough job of troubleshooting. Reminds me of when my analog cell phone in my truck failed intermittently. The service guy ended up completely uninstalling it and finally found a wire that SOMETIMES opened if I happened to put my foot on a particular spot on the floor of the driver's area. (Meaning THAT hard to nail down). Excellent!!!!!
ahh those pesky grounds get you every time. Where there is a global electrical issue, that is usually my first port of call.
Man, complicated repair. Shows how diversified the amount of electrical knowledge a true master mechanic must know today. Thanks for bringing us along.
At least you admitted who's "fault" it was.
I love watching your videos. This one in particular made me so happy that you found the problem. 😅
It shows how good your content is when I do not understand a word your saying but still enjoy it anyway🤣
It may have been possible that ground wire wasn't connected at any time after dash rebuild, and there was another (thinner wire) ground path that was being taken, which worked for some time but eventually burnt out due to the additional unexpected load.
That's a pretty slick anti-theft security system the engineers thought of there.
Great demonstration video.. for a simple solution. Having the diagnostic equipment, and basic skilled logic...yes. Scanner Danner would appreciate too.
Good morning Ray 🌄 man that tow truck that you invested in really paid off it really came in handy.
So glad you found the issue. - At the start of the video as I was observing, I noticed that your indicator signals were not going out completely and this I knew from experience that it was a ground issue - I did watch the entire video completely and my theory was correct as you found what you missed in reconnecting the Oops. I'm glad it was a some what simple fix. Now to put all that back together Ohh! BOY!!
`Murphy`s law at work...nicely sorted.`
What a find! When you had the dash apart with a gazillion wires hanging you missed one wire & stud you couldn't see. WOW. You solved your problem. Amazing diagnosis.
Love that Escalade interior swap
When I first saw the issues you had with your truck, I thought earth problem, but then I remembered I'm an ex mechanic and haven't professionally worked on vehicles for nineteen years. I sat back and watched in awe as you diagnose on stuff I had never had to deal with. Then you found the earth disconnected and it made me feel a bit better that I wasn't totally on the scrap heap as a mechanic. You constantly impress me with the work you do. Keep up the great work, all the best from a wrinkly old mechanic in the UK 😅
Boy you showed your talent in finding and fixing a problem that had you stuck for good. Very smart man.
Ray theres nothing worse then a internet Tech / Mechanics. To much aftermarket broke your truck !!! People these days are just so ignorant.
It amazes me the things that these internet techs say... literally no clue what there saying!!😅😅
Well, it/they did - in a way, because he forgot this ground connection while installing the aftermarket parts. 🤔😁😁😁
@@JohnADoe-pg1qk Dash was a factory part not aftermarket - the Banks pods were installed at a different time.
The excitement is real when you found the problem (through good diagnosing). Great job Ray. Also thanks for teaching us another way to troubleshoot as that is the key to actually fixing something and understanding what or why it broke.
So those folks who blamed all the extras you'd bolted in were kinda right... ;)
Not really. The extras didn't cause the issue.
indeed! it wasn't the upgrades....it was the installation of said upgrades! good news though... when you do it yourself in your own shop you always get labour covered under warranty.
@@21Piloteer fitting them did :) Which is why I wrote 'kinda'.
Well, strictly speaking, fitting the upgraded dashboard did, which isn't really an 'extra' I guess.
Funny how this is an extremely common problem. Literally a hundred wires and easily a half a dozen of them are grouped grounds under the dash. It's almost guaranteed that anyone will miss at least one connection during reassembly. What is shocking is that everything seemed to be working fine for months. And now, it finally shows itself. Nice work finding the problem Ray.
Ray, I guessed the problem was related to the DLC WHEN the system started working with the scan tool connected. However, I'm no where as good as you, and I don't have a scan tool. This was a great video. A master class in diagnosis. I've been retired from the car business for almost 20 years but cars remain a passion. Thanks so much for your channel.
Ray ,I think you aught to sack the guy that forgot to install the ground wire.😁😁👍👍
That's has to be a frustrating bug to fix. Great troubleshooting skills. Instead of the JP door locks scene, I was thinking of the scene from U-571 were the sailor has to swim through the flooded decks to close the air valves while the sub is falling apart.
When we get deep involved in a project its easy to miss small things. Amazing that ground maintained continuity . Seems like any bounce could have broke connection wreaking havoc. Best case scenario is it stayed broke until you found it!😊
That was nuts! Immediately when you mentioned it worked with the scanner plugged in I figured it was something to do with the data line or a line driver circuit, where the scanner would pull up or down the line. Didn't expect the whole box to have lost ground though. Glad it was just a ground and not a fried module! Excellent troubleshooting Ray!
For want of a wire, the truck was lost. This was a good video because you showed that you're not afraid to show us that even you can make mistakes, Ray. Kudos to you for showing us that when you didn't have to do it.
Great video, I immediately guessed there was a ground fault, but how well you diagnose it shows the professional.
Great praise from an old mechanic from Germany.
Great Success! I was thinking the scanner was backfeeding something to make everything work. And gotta love Florida in the summer I remember being upside down under a dash and sweat dripped right into my nose, bout drowned myself trying to fix something.
First off; congrats on getting your truck back to operational status! I love that you do this kind of diagnostic work. You have skills that many mechanics lack or won't get into because it's a total PITA. I watched your previous video when you were stuck out in the parking lot and you pulled most of your dash and all kinds of modules. Finally, after much testing, you finally found the problem...a disconnected ground wire in a very hard to reach area. The fix was kinda simple but getting there was the hard part. Loads of respect to you for all the patience you have. Even if I had the skills, I'd have lost my s**t and probably cursed out the truck and taken a sledgehammer to it.😂
Finding and repairing these kinds of problems is so frustrating to me. However, when you find the problem and finally fix it the feeling is awesome. Good job!
Thank you for showing that we all can make mistakes at whatever level we are at. But at least you fixed the mistake and made it right way to go Ray , keep kicking butt and never stop living dreams.
After all of my years ,55 in the repair business , i have to say if you don’t make an occasional misstep you are not doing anything. Good job finding your issue, here is the hopes that we all learn the importance of a good ground wire.
Good find Ray. Thankful you weren't high speeding down the highway.
Honesty....this was one for the archives best part 1 and 2. Title: The ground issue..personal. This now gives you that first thought on starting issues for future clients. " It's ground issue" Peace to you and family Ray. DVD:)
It's still called a nut Ray. Good job on the Dirtymax.
So glad you found it. It's surprising that a bad ground can have such a detrimental effect on communication network. Now just have to put everything back together.
Well at least you didn't have to pay a mechanic to diagnose the issue ray... A good day to you and family and great job on the diag and fix sir!!!😊😊
As a simple DIY, I'm impressed by the troubleshooting that happened here. I'm guessing that your average "pro" mechanic would be baffled too.
Who would have thought one single loose wire would cause so much hassle. That possibly cost a few hundreds in another shop just for a simple nut. Glad you found and sorted the problem. Stay safe and have a nice day.
Ray, you hit me in the eye, with the dash, I can not see. 😊😊😊😊
1992 Chevy Astro Van had the exact same issue just in a different place. The ground wire cluster near the left side top radiator mount had somehow loosened and had all 4 grounds flopping around. The area Chevy dealer service manager had it fixed in 20 minutes and didn't charge me a nickel. The good old days! Great Video Ray! Thank you!
Awesome fix! Yep, whenever things start working with the scan tool connected, it will be a ground issue
