AMD, I feel bad for the owner, the inability/unwillingness to diagnose root causes is widespread across the car repair business. 🤨
Agreed, I was also a victim from the original "stealership"
More like customer unwillingness to "pay" for diagnostics.
@@verajavi12 Ahhh, victim-blaming. Than how come some people can do it and still be reasonable?! I would say that people don't want to pay for diagnostics when crap like this owners' experience with this truck. It takes less time to do it right, and what we have here is INCOMPETENT mechanics doing half-ass work. When you throw parts as something, you aren't a mechanic. At that time, you are a parts replacer.
To many mechanic that can't fix electrical problems or don't know how to troubleshoot if there life depends on it,don't let idiots work on your car it will cost a lot more that if they didn't touch it
Same here, I already spent a lot of money on my 2012 Toyota venza and the code is still active.
This here is CLASSIC CCN GOLD!!!! This video exemplifies why AMD is the fastest growing RUclips Channel in this space. AMD is a man of integrity, intelligence, excellence, humanity, and an excellent communicator. I am so so happy he listened to Mrs. CCN and started this channel. Thank you, Brother. I often go to slepp to my own playlists of his videos.
Congrats on 1 million subscribers!
The parts cannon method of car repair is best left to us amateurs
Absolutely! Pretty much every time I tell my mechanic “it’s definitely a ____” I pick it up after repair and he’s like, nope, wasn’t that at all! I’m just Glad that I didn’t waste my time and money fixing things until they break! 🤣
I proudly fire my cannon any time I go near my car. Sometimes it works, too.
This is why looking for a new mechanic is such a terrifying experience.
From butchering up your vehicles electronics, to forgetting to tighten lug nuts, every shop visit is a roll of the dice.
I'm in your area, and I'm looking for a mechanic, but unfortunately, I don't drive a Toyota.
So let the adventure begin!
God help me.
Maybe you outta put what vehicles you have... Just a hint. There are people that live in the Shitcago area and could help you out maybe... I'm local but can't recommend a mechanic, since you failed that.
Check out “Ford Boss Me” he runs an independent shop in Shitcago. He spent many years as a Ford Tech but got tired of getting screwed over on flat rate. Now he specializes in diagnosing German cars. In addition to anything else.
@@RustyZipper Good dude. Took 2 trucks to him.
This video is the reason why many techs leave this field, being a good automotive technician requires years of training, schooling and competence. The old school grease monkey's couldn't cut it in this field today. The crazy part of this automotive service field is the lack of fair pay for good technicians. So what you end up with is a bunch of parts changers.
I also live in the area and I take my vehicles to TRS Automotive in Orland Park for repairs. Ask around, many people in the area use TRS.
What i love about this guy is his integrity and his honesty.
This poor truck. Parts cannon shooters are NOT diagnosticians. I'm glad you found the original problem and was able to fix it.
Without the proper wiring diagram your not going to be successful!
I recently have to replace an ignition coil in the rear bank my 2008 Toyota Sienna. It was a painful 4 hours of work. This was with the help of The Car Care Nut YT video. I could not have imagined how many of additional hours that I will spend without that video. This was the third ignition coils I replaced during the last 3,000 miles of my Sienna. Fortunately, the first two ignition coils replaced were located in the front bank, which were very easy jobs. While replacing the third ignition coil, I decided to change spark plugs as well since the rear bank are not easy to work on. To my surprise, I discovered that the spark plugs installed were different from the Denso ones that I bought for this job. The old ones were shorter than the Denso. I later found out that shorter plugs make the engine run hotter and less efficient on gas. The biggest problem with those plugs were that they shortened the life expectancy of ignition coils. I cursed the repair shop which serviced my Sienna for the previous owner of the vehicle. I knew the Sienna I bought used had bad MPG and some issues with the drivability. But I never suspected it was caused by wrong type of spark plug until the ignition coil replacement job.
Lesson learned. Do not trust the repair shop. They are always in a hurry. When they don't have the correct spark plugs, they use whatever they have in hand as long as the threads are the same.
Agree, never trust a repair shop for anything, no matter how simple. Every time i have purchased new tires and had them mounted and balanced they have always come out with incorrect tire pressure. Never have they set the pressure to the recommended tire pressure listed on the door panel!!
I think it's safe to say that REAL mechanic are a rare breed nowadays. I own a Toyota, but unfortunately on different continent.
If I were to live in Illinois, I would easily buy a Toyota just to know that I can rely on such a master expertise of TCCN.
I can't believe what the previous mechanic did to this car, I really feel for the owner.
God bless TCCN
You Sir, Mr AMD, are a good mechanic and an even more appreciative human being. Genuine person & mechanic with such patience & skills is really hard to come-by in today's time.
From day one of your videos up till now, your method of presentation, your level of diagnosis/repair is something I really value & find informative, to learn further from, as a DIY-er.
I hope you keep the high level of skills & ingenuity for years to come!
Cheers and thank you for your high level of information sharing!
Best mechanic on RUclips. Congratulations on 1 million subs!
The auto industry's biggest issue is the lack of competent technicians.
You always get me at “God bless them”… almost like,” I feel sorry for your mother” 😂😂😂
The truth about shade-tree mechanics. So sad for the owner. Another great video for common sense auto services. God bless
We have no idea who worked on the truck previously. Was it the owner, a friend, a hired person that stated they were a mechanic, a shop.
@@mph5896 So true, it could be any one of those. If your car is over 10 years old the quick fix bug can hit really quickly. That horn "fix" is a perfect example. None of them would think twice about cutting a hole in the dash of a 10+ year old work/commuter car for a makeshift switch. Someone has to take pride and have a little OCD like the CareCareNut to say NO, lets fix it correctly instead of conveniently.
Diagnosing electrical issues takes a special method of approach..... I can sympathise with people who don't fully understand electrical systems.
I learnt a long time ago a simple idea..... 99% of circuits use earth switching.... Meaning an earth fault for most issues.... Not all, but a lot. Working back from the faulty device will eventually lead you to the problem.... Your tool that senses both 12v and ground must be an absolute weapon of a tool.... Audible differences make it so easy.... All I can say is WOW!!!!
You had an enormous task to do and you nailed it.
Well done..... Respect to the master. 😊
@@NZkiwibandit A simple test light is what I use to diagnose most wiring issues in auto's.
There isn't a thing wrong with a "shade tree" mechanic. Ivan Temnykh with Pine Hollow Auto Diagnostics often works under a shade tree in his yard. LOL.
1 million subs! Congratulations. You and the Car Wizard were neck & neck. He runs an honest shop as well.
haha, sometimes when I watch AMD vids I hear Car Wizard's voice "but wait! There's more!"
Wizard is good but AMD is in a different league
Congrats on 1 mill amd! Damn I feel bad for the owner of that tundra glad you were able to fix it
The Orland/Homer Glen area is extremely lucky to have such a knowledgeable and honest technician and shop owner for someone to bring their vehicle in for repairs or service and leave knowing that their vehicle has been properly diagnosed and repaired either by you or your staff.
18:33 This is what you call Scotty Kilmer style repair ! 🤣
Congrats on achieving 1 Million subs AMD!!!
I love the simplicity and bullet proofness of my 2004 V8 Tundra.. that cost only 32k new.(taxes & Tags incl)
Simplicity? It has a whole mess of computers 😂
*That's about $54,000 today...*
Likewise. I hung on to my 03 Tundra w the 4.7L. Still use it for the dirtiest work on the property.
I think most vehicles hit their peak in the early to late 2000’s. Just enough technology and reliability but Now they’re way too complicated and have planned Obsolescence.
@@RustyZipper yea planned obsolescence has been a thing since the 30s 🤣. How do you explain multiple 2nd gen tundras with million miles?
I appreciate the care and gentle wisdom you show in all of your videos. Seeing the damage to that wiring harness might have given me reason to feel angry. Mechanics need to know how to properly diagnose problems. The results of incompetence and guessing is high costs and vehicles that do not get repaired.
It's a good feeling seeing something done properly like this. Even more when it's to fix bad work done earlier.
Congrats on the 1 mil!
Thank you for being a humble and honest mechanical expert who don't only show but educate all those who watches your channel. God bless keep doing what you doing your knowledge is appreciated.
I’m Not mechanically inclined at all, so whenever I need anything done to our vehicles I take them to our mechanic.
My dad was a mechanical engineer and was the Chief mechanical engineer at Hanford Nuclear Power Plant in WA state, USA.
I on the other hand excelled in Psychology and absolutely loved working with the mentally ill patients.
Your knowledge and experience is impressive.
Thank you for sharing!
🙋🏼
So very impressive!!
I wish physicians took as much car as AMD when they diagnose
For sure!
AMD, your dedication to trying to accurately fix a problem is not shared with a lot of folks in the auto repair industry these days. You sir should serve as an example to all how to treat a customer and their vehicle. I wish we could clone you!
Incompetence like that is why i work on my own stuff. Great job with the diagnosis AMD always a pleasure to watch you work.
This is why I love watching AMD in these videos. You can see he wants to call out the other people who worked on the car, but he holds back. Great mechanic and even greater human being!
A lucky Tundra to have found its way to your shop.
Lucky owner to have found you... Like always you are amazing. God bless you and your family
Congratulations AMD. Thank you so much for teaching us how to fix the cars.
You make electronic diagnoses look so easy. I’ve seen you do it in many of your videos. Great work👍👍
Unfortunately there is only one of you AMD, because the automotive business needs a whole lot more like you. Well done again, and thanks for the education.
Jose is like that kid that got told to hold the flashlight
He gets paid for that tho
As a growing technician I really appreciate the walkthrough diag with the EWD in the video. You make diag interesting and approachable.
thank you!
I'm curious about that huge oil stain on the hood.
It’s about time 😂 been waiting for video. Mr million man .. congrats
I'm glad the guy found u. Nothing is worse than diagnosing after someone else's work. I hope the guy has it for many, many miles. Nicely done! 👍
Hi AMD! In Texas, our saying, to be kinda nice for those previous mechanics, is “bless their hearts”in a sarcastic way. It gets the point across without using some other kinds for sayings 😂 I always appreciate your dedication and as I said before, I wished you were near me. You and your crew are the best!
If any young people are interested in auto mechanics your videos should be mandatory
Congratulations on 1 million subscribers!
That truck was tortured, not repaired. It's in good hands now and hopefully will live out its life getting maintenance at TCCN Garage.
The way he moves gently among the wiring and talking to himself reminds of a couple of surgeons I’ve sat in with in the operating room.
you should open a shop in every state so us Toyota owners have a good shop to go to.
The problem is getting the right auto mechanics that have the knowledge to work on Toyota. You can find Technician by the dozen from school. Calling themselves Technicians...😅😅😅
Mr. AMD, I would love to see a video about the electrical tools you use. Not just the logic probe, which would make a great video by itself, but also the crimping, insertion, and extraction tools as well as the manufacture information for the terminals used in Toyota connectors. I’m a guy with some electrical expertise, and want to do a good job when servicing my Toyota.
I love your electrical diagnostic skills!
The Tundra has "one bump" start? I do that all the time with many cars/trucks I drive. Yeah, when it goes south not so much. GREAT VIDEO!
Someday this will be a 10 million subscriber channel
Thank you for your honesty
Wonderful and Accurate diags. Love it! keep up the good work...
very thorough, great to watch.
I hear ya brother! Wiring harnesses are sacred, and should never be messed with/tapped/jumped/abused. I'm an old outboard motor tech, and know first hand what a mess this creates, especially in a salt water environment. Needless to say, electrical systems were simple back in the day. I just can't imagine the needless horrible headaches/expenses/diagnosis headaches this type of reckless work creates on today's highly complex/sensitive electrical systems. I cringe when I hear friends talk about adding "remote start kits" to their newer cars, secretly envisioning the horrible harness mess that was created by messing with the cars electrical system. I know there is big trouble whenever I see "patchlock connectors", black tape, and other horrible connections.
All that being said, that crazy one touch key start system is a something I would want to avoid for sure! I think I understand what you were trying to accomplish by cutting that ECU input to the starter to see if the problem was temporarily resolved. And, I'm guessing you were not worried about cutting the wire because the harness was going to be replaced anyway. My question is, could that ECU input lead/pin have been carefully removed from the plastic harness connector (and insulated) to avoid cutting that lead? Again, no disrespect intended, just trying to learn.
I learned about expensive toyota harness replacements when I changed the plugs on my Camry. Needless to say, two of the black plastic coil connectors broke when I attempted to carefully remove them from the coils. Asked the dealer if the plastic connector housings were available from Toyota, the answer was "no", only the $1400 harness. Yipes! I did find aftermarket coil connectors with wiring pigtails online though. They recommended "cutting the original wires" and patching their leads into the original harness. Needless to say, was not going to make a mess like that. Finally learned how to disassemble the plastic connectors so I could transfer the original wires/pins to the new plastic connectors....
OK, some lousy testing/procedures/crimes against wiring occurred here for sure. All that being said, I am not afraid to admit that I have found myself "in the weeds"/mixed up/confused many times in my career. Sometimes the harder we try, the more confused/errors we make. Perhaps the tech had already pulled that last of his hair out when he finally installed those fuel pump relays ass backwards. It's times like these it is important to step away from the project for awhile, allowing your head time to unravel and rethink what is going on. I can't tell you how many times I have been trying to sleep, going over stubborn issues in my head, until the "light finally comes on"/aha moment. Usually can't wait to get back to work in the morning to recheck my work and find my stupid mistake/assumption. All that being said, I realize that today's shops/dealerships are highly stressful environments, techs are rarely afforded to luxury of putting a project aside to "think about it". Always good to get another opinion from a trusted coworker, two heads are always "better than one", especially in a stressful/confusing diagnosis situation.
NICE! More videos like this! Love the schematic/details provided while TS'ing.
Wow thank you for this video, you are one of a kind sir. Been watching your videos for awhile now and appreciate everything you have taught me personally.
Wow. FANTASTIC video!!
A brilliant genius for all your Toyota needs! Man, would'nt it be nice if there are more fantastic mechanics like him out there! Awesomely awesome awesomeness YES. 👍💖
Very good video 😊
Really enjoy your channel and your videos. You explain things that even I understand. Thank you. Ottawa Ontario Canada.
Congrats on 1 million! You deserve it and many more!
I love these type of videos. I do alot of electrical troubleshooting so this work is right up my alley.
I am impressed with your troubleshooting skills. Thanks for a great video.
Great job. Thanks
Very well done Ahmed! You are a very patient man to have to deal with these types of problems. It is frustrating to see how some mechanics butcher the very fine factory wiring when all they needed to do for testing was use the appropriate tools to back probe the wires in the connectors.
Thank you for your attention to detail. This reminds me of the troubleshooting I did in my 40 year career of commercial air conditioning for data and communication rooms.
Judging from the splice connectors found next to the ignition... we could assume that there was a aftermarket alarm/inmobilizer/remote start at some point. Sometimes installers connect it directly to the horn instead of a standalone siren. Pretty sure that the horn cable was left cut open when that alarm was removed.
Aaaaaaaalso I would bet a hundred bucks for that to be the cause for the malfunction in the ECU that caused the starter to suddenly trigger. The remote start module could have damaged the ECU or the installer fried something.
...judging for everything that our beloved AMD found here... pretty sure was the installer xD
1 MILLION subs!!!! Woohoo!! Congrats ya'll!!😁
this is why i love your videos
Chapeau AMD, this is true dedication.
Great video. Thank you
i just found out my 2009 Pontiac Vibe has THE ONE CLIC START , thank you Ahmed i was wondering some times why it keeps cranking after i let go the key , stay healthy we need you ,
Thanks again for another great video...!
Great video as always. I was worried about all that oil sprayed all over the inside of the hood…..I’m surprised you didn’t mention anything about that. Very informative and I learned a thing or two as usual. Thank you!
Congratulations on hitting 1 million subscribers 🎉🎉🎉
You are the best Mr AMD!
Great work.
Congrats on 1M subscribers! Here’s to many more 🍻
This was an outstanding video.. love how you walked us through the diagnosis with the wiring diagram. Would love to see more videos like this. It still amazes me how anyone who lives in like a 25 mile radius of of your shop wouldn’t just bring their Toyota/Lexus to you all the time rather than deal with hacks.
25 mile? Heck, I wish he was within 500 miles!
As an electronic specialist all my life (I am 83) I agree with your repugnance for those damned "Knife" style connectors. Molex connectors are absolute crap as well. Oh! I forgot ....butt connectors are also crap EXCEPT.... I don't know the manufacture, but there is a QUALITY butt connector or splice that usually has a blue plastic jacket & there are TWO rings on either end of the connector.
They can be had with a "glue internally, so that a heat gun will flood the wires inside & seal out moisture, or they can be had without the "glue". They are referred to as "aircraft" splices, but I doubt the aircraft industry used them I keep a box of them with my "GO" kit for places where moisture may be a problem. In most cases I prefer a soldered connection, or better still, soldered & crimped.
Your videos are ALWAYS first rate. Thank you !
Very educative on automobile
I’m a retired electrical/radio frequency/IT engineer and have seen many technicians that thought they knew it all that couldn’t troubleshoot or rewire anything, so this doesn’t surprise me in the least. I know that if I have a problem with my highlander or rav4 I’m going to attempt to get it from Indianapolis to you even if I have to trailer it.
*Wise idea. Over the years have seen plates from Florida, Texas and Cali in his shop.*
Very good video continue video with tundras please
Four (4) starters? Doesn't the intake manifold need to come off of a Toyota V-8 to replace the starter? WOW! Great video!
Thanks a lot for great content, I wish I lived closer to your garage :) I just wanted to say that I think you talked about the "former mechanics" few times too often this time. But I'm happy you didn't suggest it might have been the owner, or his nephew, which I believe is sometimes the case :D Best regards from Iceland, that luckily has a fairly good dealer.
Your videos stimulate my left brain and entertain my inner engineer! Thanks :)
Good job AMD!
Great presentation including the videographer's work. This video convinced me to subscribe and add my thumbs up,
I love watching videos with the tundra.
Sadly the average mechanic has no idea what common sense it. And it is not just working as a mechanic, but being a human being! Thanks for the video!
very well done
I Salute you for your patience and the Grasp on the Subject/s .... Allah Bless you ...
I have that feature on my 2003 4R V8 and it works great(knock on wood).
Whoever butchered up the wiring on that truck needs a visit from karma. They should be paying this repair bill.
funny enough, this is my dad's truck😂 my neighbor owns a car repair shop and he did this
This is an exclusive episode! A lot to learn today :-)

Class 8 truck mechanic .
The most dangerous person in the world is a truck driver with a toolbox equipped with a sharp pointed test light ! An excellent product to use around electrical . 3M Scotchkote FD , a coating designed for underground electrical splices .
I can see what sometimes mechanics throw parts at the problem (authorised dealers do that too). And the reason is sometimes the repair manual, not sure about other makes, but I have some experience with Toyota/Lexus, BMW and MB.
Basically, in the manual it is something along the lines of this "Code123, check this wire for 12V, check this wire for 0 ohms, check this wire for 10k+ ohms, if anything fails then fix the harness, if harness good, replace ecu one, check codes, if code present replace ecu2, check codes, if cote present replace ecu 3, check codes, if still present replace engine ECU". So basically it gives you very specific task, which is not at all representative of real life issue and after measuring just 3 wires it tells you to replace ECUs worth of thousands.
Now obviously, experience mechanic figures out quite early that there is something miss and starts diagnosing issue from experience and outside of what repair manual is asking, but this can only be done with experience, it can't be learned from any material. So that is why it is so common to throw parts into electrical or programming issues and achieve very little.
Congrats. on your new number of subscribers...
Great video
21:00 as bad as those scotch locks are, Toyota loves to use them for their accessories installs 😂
