In this video I bring you along as I have a look at a customers 2019 Chevrolet 1500 that was at the local dealer to address a customer complaint of no power steering, ESC and service trailer brake light coming on. They made the call and told the customer that he needed a new rack and pinion, a trailer brake control module and a new transmission control module! That is a $4000 repair! Then they charged him over $900 for diagnosis and "restocking fees" because he wanted a second opinion. Good news is I fixed it for wayyyyyyyy less and only $20 in parts 😉.

I discovered your videos a few years ago and came away impressed with your superior diagnostics knowledge. Time passed and rediscovered SMA again. Not a thing has changed. The last video I viewed was about bent pins in an ecm leading to almost a wild goose chase but deductive reasoning prevailed to undo mistakes from another repair shop. This video saved the owner a thousand dollar headache of GM firing the parts canon when your skills pointed to electrical problems; a ground issue. As shown, more electrical and electronic additions can create new and unusual problems. It would be miraculous if repair shops view your videos to learn about diagnosing problems. This presumes each person has basic education in mechanics, electricity, electronics, EFI systems, abs, etc and continues learning.

@user-jd5sj8jx7r 6 ай бұрын

As an electrical engineer, former tech, and shade tree mechanic since I was 14, I found this video riveting. Soon as you found the voltage fluctuations using the scan tool (so envious of that) I immediately said "bad ground" but when you showed that trailer brake module had no common wiring with the PS module I was wondering if I was wrong. I would never have expected the entire frame rail to have a bad ground connection, so great job. Couple of comments though. (1) those braid straps have a high equivalent AWG to insulated wire, and 4 AWG can only handle about 80 amps before the insulation starts degrading (melting) but this is likely an intermittent high-load so maybe it will be okay. (2) GM and every other Big 3 auto company use the cheapest crap they can get. There are marine or military nickel-coated braid straps that WILL handle that high salt environment and will have the flexibilty to handle the extensive bending that the 4 AWG won't. (3) you referred to the 4 AWG as solid wire which is incorrect, it is stranded wire. 4 AWG solid wire wont bend without a considerable amount of force, so I knew you weren't using 'solid' wire. As to the shift to park, I hope it's fixed but i have my doubts. My 2019 Blazer with floor shifter had that and it was the microswitch in the shifter assembly. Apparently GM got a really crappy switch and LOTS of 2019s have this issue. Only way to fix is to replace shifter assembly but I raised a stink with GM and they covered half the cost. May not be the case with this one but if it comes back, go straight to that microswitch. Enjoyed your video immensely and your wife and daughter are adorable. You're a lucky man and a smart and honorable one. Wish you'd relocate to the Fort Worth area, we'd be honored to have you...and no more salt corrosion issues!

That's what mechanics used to do. It seems all these "certified" mechanics at the dealerships are no more than trained parts replacers to rack up huge bills.

Worst of all is, the customer is rarely, if ever, made whole!

@@dwb812 The problem is, nowadays as a mechanic you often have to replace complete modules. There isnt even the possibility to order small spare sparts anymore. When i started as a mechanic 20 years ago you could order ever little shitty piece of sparepart, today the manufacturer only has the whole module or part to order. SImple things like wishbone bushings or new sliding contacts for your alternator so you can actually repair it for a few $ instead of replacing the whole part. Thats not something you should blame the machanic for but the manufacturer.

Great diag Eric! I actually found this video because a screenshot at 24:09 was sent to me in an email through the grapevine at work. I was the schematics author for the 2019 Silverado 1500. You definitely caught the attention of some people at GM with this video...I was asked about the written location description for ground G116. Despite several people being cc'd and replied to on the email thread, i was the only one to notice you were using identifix and not GM's actual service information. As you have probably noticed, it looks like identifix gets very early information and i'd be surprised if it ever gets corrected/updated. Just thought i'd share a little bit of insight from the other side. Thanks for the videos!

I've been catching up on SMA videos and this is the second or third one I watched where there was a Chevy with an incorrect wiring diagram. The Malibu with the dead radio (abandoning a 10 year old car is also a bad look for GM) had the fuse rating wrong - and it was wrong both on the colorized and "official" diagram. As an avid DIYer and owner of old German cars if I had to fight the wiring diagrams I'd just as soon burn the car down. Maybe it's time to rethink the release process? And chiding Eric for not using official service info? Come on guy. Unless you lower the barrier to entry (a.k.a. publish and update *for free*) it's not feasible for anyone but a dealer or a specialist to use the official publications. Lord knows y'all make the third-party publishers jump through enough hoops you could enforce some sort of mandatory up-to-date clause. At the end of the day the incorrect data is still coming from GM. Edit: Also you might want to tell whoever's responsible for Techline Connect to check 15:18 and rethink the whole variable substitution thing. Dollars to donuts "jenkins.build.number" isn't the actual version. smdh

@manlyotool1165 GM did issue TSB #23-NA-201 on Dec 14, 2023 regarding this issue. It is titled "#23-NA-201: Loss of Steering Assist and/or Loss of Brake Assist Malfunction Indicator Lamp (MIL) Illuminated - DTCs P25A2, U0422, C1595, U0420, C116C, B3205, B127B, and/or B1325 Set - (Dec 14, 2023)". The TSB appears to be issued after this video so i'd imagine Eric''s video did actually force GM to create it. I will say, techs that experience an issue that has multiple codes for multiple systems (especially if they're in the rust belt) need to consider ground path back to the battery. This is a common issue. This is not a slight at Eric, he is a great tech. One thing I like to do in a scenario like this is grab a pair of jumper cables and use those as temporary grounds to see if it remedies the problem.

@marvinbarski3804 7 күн бұрын

@@az................. I hadn't watched the malibu video but i decided to check it out because of your comment. Regarding the fuse rating, Eric literally says "the funny part is somebody has changed it...i wonder why" at the 9:00 mark. He is implying that someone put a 20A fuse in it, likely because the correct 15A fuse (in the schematic) kept popping. Being the person i am lol, I checked on GM service information and it is still a 15A fuse and the owners manual does not list a fuse rating. I even took it a step further and looked at the instrument panel wiring harness prints and engineering uses a 15A fuse. It's a 15A fuse. If you haven't found mistakes on wiring diagrams, you might not have as much electrical experience as you think. As for the release process, it has changed a ton since 2018. I personally think in the last 10 years, the GM schematics have gotten sooooo much better. All of the publications i work on are over 99% consistent with harness supplier data. IMO there are always going to be mistakes bc manufacturers don't make money on the development of service information and it is not "worth it" to spend a ton of resources on it. I was not criticizing him for not using GM service information. IDK where you got that idea, i was simply pointing out a fact. A fact that is USEFUL for some who is doing a lot of diag using aftermarket wiring schematics and is not familiar with schematic development. I dont own a GM vehicle so on all my personal vehicles i use aftermarket sources. When you say "y'all", it is implying that i am a GM employee and that i have some sort of say in who can buy the service information. GM does not develop their wiring diagrams in house. I work for a company that has a contract with GM. I'm not familiar enough with techline but id assume that is also contracted to a company that works with GM. I doubt you will find any value in what i said, you seem to be the type of person that can only find the negatives in things but i hope it at least gives ya some insight.

Eric, I'm 70. As a rule of thumb, When ever I see multiple failures in an electrical system, I always look at GROUND connections FIRST. When I was in my 20's and working at an Automotive electrical shop, I chased my tail over a car with ELECTRICAL gremlins running through it for half a day. Then the shop owner came out and LAUGHED at me and said to replace the ground strap that ran between the engine and frame at the firewall. I looked at it and said it was BRAND NEW. He laughed even harder, and said REPLACE IT ! Sure enough, my gremlin was found... Somebody Installed a junk cable and ran a ground for a CB radio install (Remember them ?) from the same ground point. Moral of the story: Ignore how good it looks. CHECK IT ANYWAY !!! And ALWAYS, ALWAYS, ALWAYS look for modifications from stock. 45 years later, I still remember that man, and his laugh...

I was trained to troubleshoot electrical with the first rule that DC power flows negative (supply) to positive (return). That's why when battery negative is disconnected the system can be worked on. If a component doesn't have supply (ground) it could get it from a different component thus affecting different systems. Most people are concerned with a big positive cable and view the negative as an afterthought if at all. Great content, thank you for your time and willingness to share your knowledge.

Thanks to your skill and honesty, the dealer and GM did the right thing. Before my 38 year career in Mechanical & Aerospace Engineering, R&D, Machine Shops and industrial plant management I spent 15 years as a mechanic with 10 yrs as a certified master technician at 3 Chevy dealerships including positions as shop forman and service manager, plus 2 yrs at UPS as a tractor-trailer mechanic so I have seen it all. We had 11 Mechanics at Massaro Chevrolet in Niagara Falls, New York and only three of us were competent at electronic and electrical diagnosis and troubleshooting back in the '70s, when many mechanics were just parts changers. While I am absolutely certain that the competency ratio had to have vastly improved since then, due to the proliferation of computer controls, some mechanics will still be poor diagnosticians and will mostly just replace parts, as this customer experienced. Thankfully there are a few extraordinary experts like you who are willing to share their knowledge with those of us who still repair our own vehicles and help our friends and families. Thank you Eric, for doing all this with grace, humility and kindness ! Sincerely, Dan Cook

Great job, young lady.

A very disciplined diagnosis. I worked in a large GM dealership and found many problems with grounds even in the San Francisco Bay Area. If the GM tech had called the GM Tech help line, they would have instructed him to do voltage drops on all of the applicable circuits before they would authorize the replacement of any module. Obviously the tech did not do the basic proper inspections or call the help line, which is free.

@theinternet9456 Ай бұрын

You are 100% correct. That dealership definitely put the wrong tech on it. There is no way all of those modules went bad at the same time. Even if he were to confer with a fellow tech he would have learned that. But Eric is the best. I've never seen a better independent and he might be the best I've seen at diagnostics.

I was a station owner and mechanic many years ago when vehicles were much simpler than anything on the road today. But what doesn't change between then and now is that diagnostics and logical thinking are the key ingredients to solving a problem. There are many talented techs at dealerships today but it seems like parts often get replaced without much thought to identifying the root cause. I've spent many hours watching Eric and marvel at his ability to tackle anything. I hope the gentleman with the truck gets his money back. That's a no brainer and the right thing for the dealership to do. And if Eric ever gets tired of getting his hands dirty, his next career should be training auto mechanics on the right way to fix a vehicle.

Ford charges a flat rate of either $129 or $159 for diag, so whether its 10mins or 5 hrs its the same diag fee. This dealership charged him to diag every single component in the complaint even though it was all related and they were clearly wrong. This guy needs to get coorperate and the media involved the get his money back and this shady stealership red flagged

They made the call and told the customer that he needed a new rack and pinion, a trailer brake control module and a new transmission control module! That is a $4000 repair! The customer didn't think this was right (even though he is not a mechanic) Then they charged him over $900 for diagnosis and "restocking fees" because he wanted a second opinion. Good news is I fixed it for wayyyyyyyy less and only $20 in parts 😉 I hope with some evidence he is able to get some of his money back.

This was an excellent example of how great mechanics use a scientific approach. Most machanics think, "X would explain this issue, so X is the problem." And then they replace X, but it doesn't solve the problem. Instead, you looked at all of the symptoms, figured out a couple of possible explanations that parsimoniously accounted for the symptoms (hypotheses), then started testing them to disprove your hypotheses (empirical falsifiability), and then tested the limits of the solution (generalizability). I suspect you had a very good science teacher at some point. :) Pair that with clear mechanical aptitude and you get a top-notch mechanic. This was great to watch, and the interactions with your family were heart-warming. :)

Particularly when three different modules start misbehaving at the same time. It's frustrating to know, for many shops, the Parts Cannon is the default diagnostic tool.

I recall my apprenticeship here in Canada. In third year we tackled electrical. I dare say half of the class couldn't grasp why charging systems only neede a voltage regulator once alternators. They also could not understand voltage drop, or why you coud only test for it when there was actually current running through the conducter. It goes to show, not everyone is cut out to be a tech, particularily an electrical tech.

@@sidvis7235 Consider the great obstacle, language itself. Is it signal, is it votage or is it current? Up to certain resistance value, you have full voltage transfer, less than you have too much current. Beyond certain value you have less voltage, i.e. voltage drop.... and that is just small potato stuff as some might say.

When my 14 year old radiator on my 2007 finally started to leak 2 years after the hose work, I went to my down the street mechanic. He replaced it all for me rad and hoses for something like $800 and nothing leaked.

I saw a news story about a mechanic went back to college to advance his business acumen, and expand his business at his shop. He had a science course requirement, for which he took biology. He ended up liking biology and took more classes on the subject. Eventually he went to medical school and became a doctor. Apparently the logical deduction process from his former career was a parallel to his new one.

Have to add my story to this. Worked with a doctor many moons ago who, I found out along the way, was a construction engineer with a good career going. I asked him what lead him into medicine. His answer? One of his employees got hurt on the job, so he took him to the local hospital. Long story short, he said "if that idiot could make it through medical school, I darn sure could." And he did. I'll finish by saying he was one of the best doctors I've ever worked with.

You are right about the similarity between bad mechanics and bad doctors. I had a problem that when I drank beer I would get swelling in my navel area and become ill. Went to my doctor and he told me to "stop drinking". That was his solution. So I was condemned for life not to drink beer again. I went to a 2nd doctor for a 2nd opinion and right off the bat he says, "You must have H Polaris". Apparently it's a small bubble or bacteria located in my navel area that gets agitated with beer. He gave me a diet to follow for 30 days and some pills to take for 60 days and I was cured for life.

Ex electrical engineer here: Really enjoyed the analytical approach and the good understanding of basic electricity type stuff. I wasn't very surprised that a dealer mechanic would not diagnose this problem accurately: 1. I don't trust dealers in general. The goal of dealers is to sell you stuff you don't need and make a lot of money on repairs. 2. I am skeptical of any mechanic on electrical issues. IMO the best way to get affordable, reliable car repairs is to find a good independent mechanic and stick with them. After a while they trust you and you trust them. Kumbaya

The goal of any shop is to sell what you need (dealership or not), and to make money while doing so. I own an independent shop after working at dealership for ten years. No car I ever worked on was sold a repair it didn’t need and I paid for my own misdiagnoses. Some dealerships are not run with a culture of theft and dishonesty, although it seems they’re getting fewer and further between. It mostly comes down to the individual and their scruples (or lack thereof). All that said, I’ve seen independent shops rob people blind out of both dishonesty and incompetence - it’s not exclusive to dealers.

Hi Eric, I'm a retired communications engineer and from my experience over the past 40 years, I find the lack of 'critical thinking' in most technical fields is commonplace these days. The training of old included fault diagnosis and repair down to component level but that isn't possible with modern electronics and it just isn't cost effective... as a consequence, higher level diagnostic skills have suffered a significant drop over the decades. Dealers and big repairers aren't investing in high quality training of their staff and only appear interested in making a buck as quickly as possible. The customer ends up paying for the poor guesswork and a dumbing down of our young mechanics, they really need to invest in people of your caliber and train their staff..... a young apprentice under your care would out shine any of the dealers staff.

Part of the issue is the good mechanics don't make flag hours cuz we don't upsell things that arent needed and we get written up all the time. OR Because of flag hours under warranty at the stealership we don't make money. A combination of both or we are way overworked most dealerships expect you to work 12 hours a day with an hour lunch 6 days a week because we aren't paid a salary or hourly. My mornings started at around 7am and didn't end till the service department closed. OR I don't know what the rate is today at the dealership I worked at but it was around 160 hr labor when I was there, these were LUXURY cars I worked on. and we got paid maybe 15 a flag hour if we were lucky and we had to do the stupid work like change oil if one came in we did not have someone else changing the oil so it was drop everything and get the oil change done. Flag hours should be outlawed. Plus at the smaller dealerships I worked at oh yeah we got a little more per hour but wasn't worth it cuz they would haggle over the price so basically they didn't care if they were taking money out of our pockets to appease a cheapskate since the shops made money on up charging on the parts but not the labor. SURE WE'LL eat that 2 hours of diag the guy put in probing out your entire electrical system not to sell you the wrong parts. 2 hours of my pay were gone. That's why there are few mechanics left that are honest and good. We get treated like shit plain and simple or we get harassed out of the business by not selling you things you don't need. A few of us get lucky and can afford to open a shop where we do right by our customers and stay in business.

Paid a local radiator shop to boil out the radiator for $50.00 and it completely cured the overheating problem. Eventually got the Stealership to refund some of the money. Never went back to them and never will. This was before the internet, now I would just Google the problem and hopefully there would a SMA video on the issue. Thanks Eric O and the lovely Mrs. O.

@@donaldlee6760 You are absolutely correct. What the dealerships and people in general fail to realize is that this type or work just doesn't pay well anymore, Owners are greedy and don't want to pay for people who are truly skilled in this area. He made this look simple because he is an experienced and good tech. It is so much harder to teach and to get techs who truly understand the concepts and what is necessary to accurately diagnose. I myself am a GM master/ASE master tech who left after 23 years because even though I was continuing to produce the quality and amount of work I always had. My wages kept decreasing and not keeping up with the times. There is actually a nationwide significant shortage of skilled technicians and as long as dealerships and manufacturers keep being greedy it will only continue to get much worse. This guy is a good tech to have caught that so quickly a lot of guys would be lost from the get go. As a lead master tech in a dealership being the guy who got these kinds of problems no one else could fix regularly I can tell you there are not a lot of guys in the industry that are as capable as they should be. I would also like to add, that this isn't a dealership problem it is an industry problem and occurs significantly more among independent shops, A lot of independent shops would never even tough this truck. So Kudos to you sir. This is the kind of guy you want to bring your business to. Support him because with all of the expenses necessary to run even an independent shop these days guys like him need your business and support so it doesn't just end up dealerships left around.

Fully trained and certified, he tired of the "dealership mentality" of numbers over service and was able to become independent. Over the past 15 years he has been able to build a very profitable business which is based on the most important asset of all...INTEGRITY.
