I was waiting for Luna to snatch up a mouse and say "Here's your problem lady!

Finding this issue isn't the miracle, the miracle is finding a smart, honest mechanic that doesn't take the parts cannon to every repair.

I’ve been an electronic tech since 1983 and you are by far one of the best troubleshooters around. You should not sell yourself short, there’s a lot of “mechanics” that would never find those broken wires and would just give up after the cannon was empty. Keep up the good work, it’s so refreshing to to see an honest mechanic that knows what he’s doing!

One of the few KZfaq videos that actually show a true technician at work. I hope many viewers watch and appreciate why you pay for a "True" technician to diagnose and repair their vehicles. Thanks for taking the time to create this highly educational and interesting video.

7:08 Luna giving it the cat scan. OMG.

Cat immediately identified Mouse Damage. Smart Kitty!

I've learned that the go-to diagnosis is "broken wire". But you are incredibly fast and efficient in finding exactly what wire is broken.

Eric, I was an Appliance repairman for 27 years. A technician who loves his job and cares about the customer is who I was....and it is who you are! Just that makes you Special! I love watching your videos! Treat Mrs. O like a Queen...after all she loves you!

When you said “Cat Scan” and then I seen your kitty I about peed myself! You are the best! Thank You I needed that!

Dear Eric, I'm retired at age 68. Back in 73, I worked in a machine shop. A year later, I got an electrical apprenticeship in a factory that manufactured mining equipment including locomotives. As a side job, I worked in a local auto garage/body shop. When I became a journeyman, I moved on to working on locomotives in the railroad industry as an electrician and a technician. Years later, I became an instructor to teach people how to fix locomotives. As time went on, I was promoted a few times until I managed a railroad training department until I retired. I trained people for the last 30 years of my career. If your ears were ringing the other day, a retired co-worker and I were praising you. He was my best railroad apprentice who became a close friend and retired as an electrical technician. We both have nothing but praise for you. I'm inspired, humbled and grateful that I can follow your adventures! You ARE a GREAT TEACHER! By the way, Einstein also once said, "why should I clutter my mind with something I can look up?" Best Wishes Always, Tom K

I will have to admit that this is one of the best troubleshooting I've seen. If I could find any shop near here that was half a competent or willing to put the effort in I would let a shop do the work on the car. I understand you closing comments about receiving praise. there is nothing preventing other shops from doing things like what you are doing. its technical but not impossible. The difference is character- willing to put in the work to do it right and with integrity. Last time I trusted a local shop I knew there was a leak in the turbo coolant tube- not a fun driveway repair. so I asked them to do it. they wouldn't until they used their pressure tester and magically came up with a coolant tank leak that wasn't there. I figured this was just the price they were punishing me for doing the analysis myself so 375 dollars later they tried giving it back without doing the fix I asked to be done. then having their lead tech look at it again they found the original problem in the exact location I found it, and fixed it - another $1000 and week sitting in the shop, then a few days after getting it back, started having issue with acceleration and found they had lost the connector for the throttle cable and had simply left the end hanging on the knob waiting to fall of in some bump on the highway hours from home. And this is one of the more trustworthy shops in the area. At least I know they are scamming and just have to put up with it to get them to do things I don't have the proper tools to complete well. I feel for the people who don't even know and don't have someone like you who is trustworthy in their area. Thank you for doing the job right and caring to be one of the rare honest ones.

A real mechanic doing the actual diagnosing. Love it.

Eric, WHY on earth do you have to be over 14 hours away from me... I swear everyone needs an "Eric/ SMA" local to them. Great work as usual.

Don't sell yourself short. I would say most of us are not working mechanics and only run across this stuff once in a blue moon and the way you break it down and your uncanny ability to sniff out broken wires is nothin short of autistic savant stuff. Didn't mean to sing your praises, but I haven't seen a better teacher in field applications on this stuff yet. Classroom diagnostics or any classroom teaching falls way short of what you find in the field, and I am mostly referring to the HVAC trade, but is the same for most fields. Your skill is being able to teach practical field applications that is then easy enough understand. I think part of it is that you take the time to move the camera so we see it all and give us a proper explanation. Dammit, I did it again, more praising. OK. You piss me off when you make it look so easy. I struggle. Cars are much different than AC stuff. Anyways, take it for what it's worth, or don't. You have the gift. Thx Eric.

Your electrical vids are my favorite. Mind you, I have the face of a Labrador retriever trying to understand someone reading Shakespeare most of the time. But each one of these peels back the mystery and magic of automotive electrical wiring. Thanks!

Thanks for taking the time to show us your troubleshooting steps! I’ve learned so much from just watching!❤

It’s good to see Mrs. O in your video. Every video is better with Mrs. O.

Rare qualities in a mechanic: Honesty Integrity Fairness Your years of experience Willingness to go the extra mile. There is an old saying, easy for the person that knows. These qualities are in YOU not everyone. That’s why you are praised. May be easy to you, but the world needs more people like you. Oh, and your sense of humor and humility…. On point my guy 😂

I love soaking in knowledge and you do a great job at picking a plan of attack with the most affordable way possible. I could spend 20k on the equipment to analyze the CAN bus, but a simple meter for 60 dollars can help me pinpoint an open circuit in the network. I've been in computers, networking, and automation for years and this just feels like home to me. I enjoy learning every day from youtuber's like yourself because it will help me build my business and help me succeed in life. Going from being laid off, broke, poor, loosing the love of my live over it, working at a dead end job at a walmart to having hope of being someone and doing something that I love doing and making a living out of it helps me greatly. Thanks again for all you guys do.

Nice to see someone that has a real technical approach to troubleshooting. I worked on computers for 50 years and you did everything right.

Mr.O, don't sell yourself short as this is a miracle as shown by the shop trying to sell the customer an instrument cluster. No one wants to diagnose anymore, and all they want to do is shoot the parts cannon. You are one of the old-school talents that still does diagnostic troubleshooting. You, Ivan, and Scanner Danner are just a few who look at the problem and take the time to find the root cause as best you can. This is why so many viewers seek you out for your expertise. Please don't be mad at your viewers for wishing we had a talent like you in our area. The alternative is to be overcharged, pay the parts cannon shop, and still have the problem after letting go of hundreds if not thousands of dollars and the shop saying we don't have an answer for you now pay me.

Hello Eric, A few weeks ago I worked on a 2015 Rav4 that the emergency flashers were on all the time and the customer had to disconnect the battery. I also saw signs of mice intrusion inside the car. scanned the car and no codes of course since the battery was disconnected before driven over to my garage. disconnected the hazard switch and 4 ways still flashing. Checked all data wiring diagrams and the signal lights are controlled by the combination meter. Removed the combination meter and found a large mouse nest made out of the insulation material Toyota uses to insulate the HVAC ducts. no visual damage to the wiring. checked the hazard switch wiring at the plug that connects to the back of the combination meter and the switch, functioned ok which led me to the combination meter. took the meter assembly apart and found signs of mouse urine that made its way to the circuit board. pulled all the gauge needles off and LDC display out and removed the board from the housing. tried to clean the board with deoxit and a nylon brush. ended up using some WD-40 and it cleaned the board of all the mouse juice. I cleaned all the plastic parts with soap and warm water. reassembled and installed back in vehicle and problem solved. Thought I was going to see you find a nest behind the cluster on yours today. Also did you see Sherwood at Royalty Auto service was all excited about finding the "Green Crusties" on an Audi under the fuse/relay box under the hood? He gave you a shout out. Thanks again for your posts and all your time, see you again on the next "What's up Wednesday" Arkwright Dave '

Dear Eric O. Good day to you, and to all your viewers. My name is Raj, located in the Caribbean, I look at your videos all the time. It's always a never ending learning experience on your channel and videos. You are very good at what you do, and your explanation on your videos are very clear, and easy to understand. You make your type of job, look very easy, in which most of us who does the same, know its not, by our experience. You do help a lot of people around the world by making these videos, and I would like to thank you for sharing your knowledge with all of us. Your determination in figuring out the wiring diagram is truly amazing, you really are relentless, giving up isn't your type of language, and that looks very good on you. Thank you again very much. I just have one thing else I would like to say, I hope it don't get you angry, it's just an advice?. In the future if you ever come across a vehicle that was rats infested, and its clear to see, PLEASE!. Let the customer get the vehicle steam clean!, before attempting to diagnose or repair anything. Due to the world wide health issues we all when through in the pass years, we all should take our health more seriously, For ourself and our families. Rat droppings and rat urine is to be taken very seriously, wherever there is dropping there's urine!. A friend of mine who's a good mechanic like yourself, he did the same for his friends wife vehicle, not taking the rat droppings seriously, and repaired her car. We all told him about it, and he said its all in the work, but he promise never to do it again, a promise he kept on till the very end?. After repairing the car a few days later, he took his work uniform home to wash, his wife's job, something she always does laundry. A few days after, she and her son got sick, went to the doctor got medication and came home, the next day things got worse. The both of them had to go to a medical clinic emergency room, they were having problems breathing, and walking. The doctors did some tests and said it's Rat poisoning, they were all shock, were did they got that from. The doctor ask if you were doing renovation at home, moving, cleaning or if anyone was in contact with any rodents within the past couple of weeks?. It took him a few minutes, and he realize it was his work uniform, and all the laundry she did that day at home. He got angry with himself, and took blame for all of it, we told him your family needs you more now than ever, so keep it together, we'll get through this. His wife is one of the kindest person you could ever meet. His son started showing improvement in about four days, but his wife got more worse, and she were now fighting for her life. I believe God, heard all our prayers and save her life, after about three weeks of medication she started to improve. She and her son made a full recovery, with a life changing experience, that we all will never forget. So to Eric O, and to all those viewers that took the time to read this comment, Thank you. Always remember NOJob! is worth the risk of your health and your family's, because you never know when your luck could run-out!. Please take Rat droppings very seriously in the future!, It can kill you. Be safe and take care to all of you. Bye, cool, Raj. Thanks again.

Eric love watching you diagnose a problem. You are a good mechanic because you just don’t throw parts at the problem. My brother is also a mechanic, now retired and he and you work allot alike. Thanks for the great content.

Ok, so from a 'technically-minded viewer' perspective Eric, you showed us the 'problem, lady', shared your thought process, held our hands while you diagnosed it, explained *how* you diagnosed it, and demonstrated a real-world repair that was very suitable for this age and mileage of vehicle. Then, right at the end, when we're out here whoopin' an' hollerin' that it works, you gave us an encouraging outro that will inspire others to believe that they can also do it the right way. Your business and your YT channel are successful because you genuinely give a shit, and we've all suffered at the hands of shops that don't. None of that is blowing smoke anywhere fella, 'tis just what I see. You are a great communicator, and your knowledge and skills are clear to see. Not everyone has the ability to think through a system, and imagine defects in their heads so they can get to a fix quickly and effectively. Yes, we all need the manuals and diagrams, but they are useless unless we have the knowledge to interpret them. I love being able to demonstrate the cause of a defect to a customer, not because it strokes my ego, but because it a) helps them understand what's wrong with their plane and b) gives them (and me!) confidence that I know what I'm doing, and that I can fix it, and get them going again.

Eric, I appreciate your humility, I really do. It's quite refreshing. But seriously... you opened the hood, smelled a mouse and pretty much knew that a gnawed wire was going to be the problem and that no new cluster was needed. That much was your experience informing you. Then you busted out your PRO diagnostic skills (and tools) and BOOM! found it and fixed it. That was your skill at work. Again, I totally appreciate your humble attitude, but you are definitely not ignorant! Besides, we all know that if you get too big for your britches, Mrs. O. has ways to keep you humble. 🙂

You are very good at troubleshooting and repairing electrical problems . You have a divide circuits in half approach which speeds up the process . I can tell and appreciate the process . I’m now retired but did troubleshoot and repair for over 30 years in the Banking Industry Security and ATM system. It takes a lot of experience combined with technical understanding to accomplish what you do . Your humble and professional skills and knowledge shine through the videos you produce . Thanks for sharing . I enjoy watching and learn from your experiences. I also do a lot of my own vehicle repairs too .

You're the best mechanic I ever seen work on a car

What makes you a Great Mechanic is: You take the time to Diagnose. You also take the time to show/explain/teach.

The plural of mice is meeces. As in, "I hate you meeces to pieces." Just ask Mr. Jinks the cat.

About the coment at the end that you are not the best person to teach diagnostics: That's not true! You are very good at explaining this kind of stuff! Through watching videos on your channel I got the confidence to do some car electronics troubleshooting myself. You showed me that it's not that hard and you only have to follow the trail of the clues. And your sentence "if I can do it, you can do it" at the end always motivates me. Thank you very much for all the great content!

The Lady will call you a saint, you are a great mechanic, 2012 Toyota Rav 4 lives. Thank you sir.

Great diagnosis, but loved the CAT scan lol

Sorry Eric, but you are absoluttely correct that other shops would not be able to diagnose it. Thus why it came to you in the first place with the "diagnosis" that the instrument cluster was bad. They are simply parts replacers, not diagnosticians. Love to watch you work. Thanks for all the hard work you do.

I almost miss doing that, but after 47 years I’ve had enough, but enjoy watching you go through the wringer what I did so many times. You do a great job and you do a wonderful service for your customers. Keep up the good work.

No, you are not a miracle. But you are an amazing professional mechanic -- knowledge + experience + great temperament + tenacity + honesty + a bunch more.

Aside from the fact it's a rare Toyota in your shop, this is immediately one of my favorite videos, Eric. One of your best explanations on that wiring diagram (even I could understand it!). When I heard the "soLder" comment, I thought sure we'd hear a BigClive reference!! Thanks as always, Eric!

A lot of Mechanics seem to not give a shit about Their Customers, you do and I love Your channel.

So... the car got a cat scan and found the broken wires. You are a good tech for actually finding the root of the issue. You are like me, a rare breed who will actually fix it correctly.

Don't care how humble you are...true genius.

You might not be a miracle worker in your opinion, however you are a very proficient and very ethical worker who provides not only affordable repairs, but also the necessary repairs without the "fluff" and without the "on-selling" of unnecessary parts and services. You have customers interest at heart, and us as your viewers.

Great quick and easy to understand video. I used to be a wrencher for the the Army/ Dept of Defense, now sitting on the other side authorizing stuff and I love watching videos where a person, and in this case you, explains the why and how on diaging the correct way and finding the simple fixes as this one.

That is why I watch your stuff along with some others on the KZfaqs. Its to take in the diagnostic thought process and also the work ethic habits provided here so I can apply it to whatever I am working on. You are never going to fix something to everyone's satisfaction and knowing where the line of "good enough" is takes experience. It's one of the main upsides to things like KZfaq.. I have the ability to learn from your decades of learning and get to enjoy some humor along the way. As always, thanks for the video!

This SMA video had it all! The dad jokes, the pestering Mrs O. The well thought out diagnostic process and the ability to sniff out broken wires. I know you say this is simple stuff any anyone can do it, but the fact is, they won’t.

I learn from you every episode, Eric. And I have been fixing Vehicles since 1977. Thank you, You're a Great Teacher! ASE CMAT L1 and GM Master Certified. Now semi retired.

Your an honest man,and humble, I'm 74 and in Mississauga Ontario Canada. Great job and always fellow your jobs.

You are one of the best I've seen and enjoy watching you. Some people have a place in their head that maps out wiring others see a pile of spaghetti with no end. I'm a old school mechanic and supposed to be retired. I get the jobs that the guy in the shack can't fix. Thank goodness you have shown me the way.

One rationalization a day. I like it. You discovered the problem, saved the customer a ton of money, and came up with a "perfect" solution for an imperfect real problem, and found some humor in the situation. Your wife added a wonderful touch. Devine comedy. Thanks, GB.

40 years ago I was taught to check for signal at the end of circuit, if signal not there, check in middle, then check halfway back until you found the signal. This helps locate the issue. Which is exactly what you did, Great Job!

Eric... I so appreciate your channel (and more importantly your demeanor and the way you talk through the process!) I've worked on my own vehicles for years, and for 25 years I've been a golf course superintendent who is required to be the equipment manager as well. It's my job to keep all our equipment running... your thought process has helped me tremendously! Start with the simple things first, test from the beginning and work your way back. Often times it's something you might not have originally thought. I've solved so many issues by isolating known working systems and finding what caused the issue, rather than just throwing parts that might not fix it at it. Thank-you for doing these videos, you have a great personality and are relatable to so many ("if I can fix it, you can too!") Much appreciate your approach and how you can work through the problem calmly and show us along the way that it really is most of the time something that may take time to find, but more easy to fix than you first thought. Thank-you so much! (and Thank-you to Mrs. O for brightening the room when she makes an appearance!) All the best brother!

I've learned to make a plan to track down problems from you. The first thing was getting the wiring diagrams. It's helped me track down all of the little problems in my 2004 Dodge Dakota. All I have left now is the wiring pigtail to my oil pressure sending unit and one in the key ignition wiring. Thank you I'll keep watching. I pick up something new every video.

I agree with everyone. Don't sell yourself short Mr. O. The ability to know what to do, and what not to do is vital. Anyone can be a parts changer, but knowing what and what not to do shows a true mechanic.

I learn more from watching your videos than I do through courses through my dealer 😂 Thank you for sharing the knowledge you have. Greetings from Sweden.

One of the best diagnostic videos I have ever seen. I feel like I know more about analyzing wiring diagrams than I did before. Thanks for this!

People sing your praises because you are very well versed in your troubleshooting and diagnostic process. Another tech was quick to say it was an instrument cluster. I have had so many mechanics lie to my customers and even myself when I got my first car. You have shown countless vehicles come in from other shops and even dealerships. In some cases took customers on a ride and still not fixed. You learn and continue to improve your craft. That is why I watch you and it improves my skills too I notice. So thank you for being a good teacher.

Wait I thought this was SMA not Humble Mechanic?! LOL I’m almost 60 and have always had used cars with issues on issues. The hackery that takes place in shops is sketchy at it’s best and is a full on shit show on average, so to actually be able to watch a mechanic who takes diagnostics serious and can convey the logic and application of that logic is GOLD my friend. If you stack those diag skills with the sense of humor, the top of the line segways and the quality camera and editing…your gonna get praise on top of praise my guy. The whole humble thing just cherries the whole shabang. We appreciate you young man, on many levels. 🙏 Luv me sum SMA video❤

I know Eric’s name is all across America as 1 of the best diagnostic in the country if he can’t fix it. It can’t be fixed. Thank You Eric for another awesome diagnostic video

Most Awesome auto technician in the country! Your community is very lucky to have you in their midst. I am hoping that your technical expertise will not be lost to the ages. Your KZfaq library should be included in every certification class.

You are good. I was a mechanic for 45 years still Mechanic at 73 Electrical used to always give me fits. I just love the way you found this problem. I love watching you and your wife interact. It’s a nice set up. Nice show. Keep up the good work.

I know exactly what you're talking about. I was a field engineer for general electric medical systems 35 years. And you're right I don't know what it is but whatever reason I didn't seem to have a problem troubleshooting that equipment. And then I watch you and what you do and it's exactly the same thing. Like you I didn't consider myself anywhere near as smart or educated as some of the guys I worked with. But when it came to troubleshooting like you it just seemed to flow for me. Enough blabbering as usual great video.

Excellent video and diagnstic approach! No parts required as Ivan would say!

I've been turning wrenches since the 80's and I still have so much to learn. You can only learn so much at the dealership under a time restraint and stress. Your videos help those who never delved into diagnostics to not be afraid of wiring diagrams and point of search. Thanks for sharing your knowledge and time.

Really good watching an intelligent and logical approach to finding a problem!! And… no irritating background music either!

You’re right Eric, “anyone” could have fixed those wires. Only the “talented ones” knows which wires to repair. I was in automotive fixed operations for 44 years and know that a majority of techs don’t have your diagnostic skills. That’s why other shop tell the customer to take back to the dealer or your shop.

Eric your an amazing mechanic my friend. When I went through mechanic training for NYC Transit for the buses we were taught an entire class alone just on Multiplex, Dinex and all that. I have to say it’s great to see that this knowledge I got from here literally can be put to use on our cars too. It’s such an amazing thing to see how buses and cars are so alike when it comes to repairs even down to the electrical

Love watching your videos like watching my son work he's been a mechanic for 38 years and like the way you find the problem also your a good family man stay safe always

As always great logical troubleshooting. I’m retired maintenance electrician and auto mechanic. We used to troubleshoot network issues like this only our devices were often hundreds of feet apart. We used a spare terminator resistor to narrow down where we were broken. Sometimes frustrating but I loved electrical troubleshooting. Sad the world doesn’t have more techs like you.

You are too modest Sir! You are one of the ones that have a Diagnostic gift! LIVE WITH IT!!

Great video! I followed your thought process all the way through without a problem. I personally think you do a very good job of explaining/teaching while you are on your quest for the problem! Thanks!

Excellent electrical/electronic troubleshooting. I was a field engineer for a computer company and the diagrams you use bring back memories of me tracing signals with logic prints for discrete component processors 45-odd years ago. Well done!

Brilliant, thanks for taking me along on the journey

Another terrific detailed diagnosis. Thanks for sharing the process. Being a retired appliance service tech & trainer, I appreciate your approach in diagnosing issues. Logical and organized. It's really frustrating seeing a shop throw a poor diagnosis at a customer. If you hadn't hit the brakes for her and said 'whoa, I'm gonna check this out before we talk cluster replacement' she would have wasted more time and money taking the wrong path. From my perspective, I am a old school gearhead trying to learn new school repairs because I'm stubborn & want to fix my own stuff . . . which is really tough with the new vehicles! I have invested in a few diagnostic tools, which has helped chase down numerous issues, but something like this would have been tough without a few of your higher-level diagnostic tools & access to the wiring/schematics etc to locate things.

The people who work on vehicles at the dealership watch your videos to learn how to be a Mechanic.

I really enjoy your videos. I just like to see you work through the problem. Thanks! I'll keep watching.

Wow Eric man that was actually pretty fascinating to watch as you went through all of that. I may not have understood everything that was going on but I got the main thrust of the diagnosis and the repair. And like many others here I think you're a wonderful mechanic with a great way of looking at and figuring things out. Awesome video brother♥

I agree 1000%. What you did is basic troubleshooting that anyone can do, given the correct information. That's exactly what I do.. That's why i love watching your videos. I'm troubleshooting along yelling " The connector is RIGHT THERE. You can SEE the twisted pairs lol. Aces content Eric. And you just explaining as you go, is a wonderful approach.

Hi Eric & Mrs "O"... I've enjoyed watching your KZfaq Videos over several years. I'm a retired 74 year old fan. My Son is an ASE Certified Mechanic in Southern California. He also loves watching your channel. The mice can make anyone a lot of money if you have the right mindset and follow the clues and your tools. GREAT JOB Eric..!!

Excellent job!! I love these types of troubleshooting videos!! Keep up the amazing job 👏

A new instrument cluster, I don't think that would have fixed it. You are the man my mechanic works like you, tracks the problem down, and fixes it. Thank you

I think your way above most of us on electrical problems,not letting ur head swell is why i enjoy your channel.

You are an amazing mechanic because you save the customer money. So many mechanics are just parts chimps and don't actually solve the problem.

Well done, good Sir. Thanks for the lesson. Greetings from Ohio. I've been escaped from NY for 43 years and counting.

I have not had the chance to watch you for a while and the you hit me with mice, a cat and this level on genius troubleshooting... it is so familiar but also very very interesting and entertaining. Thank you for the good work and work ethic.

You are amazing....! The troubleshooting process you do is a giant puzzle, and I love watching you solve it....! Great Job....!

Married for 30 years come July, and every spring my wife still puts on a spring dress for me, too. I hope she's still doing it another 30 years from now. That was a thoroughly educational and entertaining video, Mr. O., thank you for taking us along.

What I find real nice is the fact that everything on the network went to crap the can - but the SRS was still working and reporting. This is perfect security. Kudos for Eric to fix it how he did instead of billing the customer a whole harness, a plug and six gazillion hours to trace all that in order to install the new harness.

I was very impressed how you troubleshot the problem. I come from an audio engineering back ground and never done any repairs on car computer systems. But watching you get the schematics, even look at the traces on the scope and meaure the 2 resistances, I was very impressed. Wish there were more mechanics like you..well done!!

Brilliant work, Eric...you continually impress me with your diagnosis over and above what many mechanics do these days especially here in the UK.

Eric, I am not an automobile mechanic, but about 3 years ago I watched you diagnose an even more tenacious electrical issue. I wrote software for more than 40 years, went to university, but they didn't even touch on diagnostic practices. I learned it in the field over years. As I mentioned, I ran into one of your videos years ago, and forwarded to a coworker, and told him this guy diagnoses problems in much the same way we do. Isolate the issues by eliminating obvious non-failures. In software it is often binary - this half works, this half doesn't - rinse, repeat. I find it totally unacceptable that any qualified shop could not even notice a CAN bus failure in a modern car. That is one step above "Is the power on?" I've seen too many vids where "parts cannon" is the default response. Whole new dash cluster would have cost thousands and not fixed the problem. In fact, Luna did a better job than the "other" shop as to the nature of the issue. Some shops fire a parts cannon either out of ignorance (hopefully) or out of out-right malice trying to drain someone's wallet. From your comment, you are not a "miracle worker", you are simply very competent at your job. Perhaps you are right - automotive tech schools should teach diagnostic skills and electronics skills. Hell, I can set the points on a mid-1970s VW, but there is no way I could figure out the electronics of my 2020 Nissan Leaf.

We would love another day at the shop like you've done in the past.

Great diagnostic. You understood and found the network problem. Understanding the network and your explanation will help me in the future.

Watching your videos has helped me be able to keep my cars on the road. Thank you for the knowledge and entertainment.

I'm an emissions inspector in northern va and they wouldn't care if you got a cat from Amazon but better not get caught selling a used one also our waiver amount is 1030 bucks.

Normal debug methods and problems with learning it. It took me 2-4 years out in the field getting the crap beat out of me and working with my boss over the phone until I learned how to think. The classes help, but eventually you need to pay the piper and spend the time and take the punches and get back up.

Mr. O, you have the best scan tool out there, between your ears, and you aren't afraid to use it!

You are THE best mechanic I have ever witnessed!

This channel alone has made me a step above the rest. I never knew how to diagnose electrical problems until I came across your channel in 2018. Thank you Eric O.

Another great informative video. Also watched the one you linked earlier for Royalty down south where they gave you a shout-out for the green crusties. Could the network communication be wonky when wiring and resistance tests show good results?

Dude, your great, I've been working on my own stuff because I'm poor, and I struggle with this stuff, I appreciate your patience explaining your approach to trouble shooting

Catscan 😂 I love it !
