mate your the best, its like you always said its a process of elimination, just imaging if cars were still old school, no computers, check fuel air and then fuses, 9 times out of ten, it will be a fuse or fuel or basically electrical system, now days you need a PHD in auto electrical meaning the scan tool does most of the work, lol :) Keep up the great work always watch your channel, you are a scholar and a gentleman. 🚗🚗😊😊👌👌👍👍✌✌

I once owned a Hyundai Santa Fe ('09 I think) that had this same intermittent transmission problem. I finally figured out that shutting the engine off and restarting it would usually fix it. Eventually the issue was permanently fixed by a deer which entered my path one morning and ended the lives of both the Santa Fe and the deer. Thanks for the vid.

Wow, an early one, my coffee isn't even ready yet. That was a good one. Even a trip to Wilberts.

Eric's ability to sniff out "Automotive Electric Gremlins" that other shops cannot find or figure out is now the stuff of legend. He is the Car whisperer for sure. The lesson taught to us today, is an important lesson in "Assumptions" that can lead amateur Gear-heads down the path of diagnostic defeat. Thank-you for the terrific content, and for showing us how you arrive at great solutions to complex problems. Unlike watching TikTok, where viewers feel they have lost 3 hrs of their life-they will NEVER get Back; when I am done watching another Super-Installation by Eric, I really do feel smarter and like I honestly learned something that will benefit somebody I know 1 day! Thanks for all you do at South Main Auto, we the faithful are humbled by your knowledge and for being a creator sharing it on KZread.

Son of a gun, that diagnosis was actually fun. Keith is a huge asset to the automotive community.

That was some absolutely brilliant diagnosing, Dr. O. Looks like many others had attempted to figure this out and failed. They just needed to call the Big Guns at SMA!

I really like that you use the junkyard as a parts source. Very cool!

A trip to the yard. I know it's going to be a good video even before watching. !!!!

Great diagnostic, Eric! Very clear minded approach! When is a relay not a relay? When it's only a shunt, to use the same harness in a different vehicle model! Nice trap for young players 🙂

Eric O, I love watching your videos, especially when Mrs. O makes an appearance. I've mentioned this to you before but I'm not sure if you read my suggestion and don't want to use it; or you haven't read it yet. If you do see this, mention it and I'll stop but for now allow me to offer my suggestion for a new sign off. "Remember folks, if I can do it, you can do it. If we can't do it, we'll get Mrs. O to do it. 🙂

Diagnosing the problem and talking to the KZread audience, and still had time to holler " CHEVY THUNDER " 😂😅 love it

Makes me so glad we don't have inspection. I would have never guessed changing a bad part to a good part would make it fail.

Love it when Eric finds a complex problem ... checks service data, does some logical diagnostics and discovers what the mystery(s) is ... and has a fix .... and we know he loves a trip to Pick n Pull

27:40 LMAO...it dawned on me that the lawnmower guy is back!

As though as Mr. O we'd love going to Wilbert's on your videos , That place is a gold mine .

That junk yard is so neat and organized. Unlike the ones around me.

One of the advantages of living in South Alabama. It doesn’t snow . And our cars don’t rust out

Always, and I mean always check which hole!!

Used to own an NF body Sonata with the V6. Had a 2.4 version once as a loaner. Was very glad to get my own car back.

I had same thing happen to me with a John Deere 3800 Telehandler. Ended up talking with a guy in Germany to find out that 1 relay out of 26 relays was just a jumper. Employee had been swapping around relays because of a clicking sound from relays.... Not sure what bill ended up being but it had the original service call (90 minute drive 1 way), Trucking to bring it back to shop & my time working on it (including dealing with JD because of bad wiring diagrams).

Love watching you process through the issue and come to the correct diagnosis.

Man o man, without that bonus PCM in hand that could've been a rough diag. Having two issues along with needing to clear the code to verify really can compound the head scratch.

"Lawnmower Man" is at it again 😂🤣😂. (At the end of the video).

The best is at work again, and again you nailed it. Too many parts changers out there that can’t fix things. It takes smarts and a person who lives his work to do what you do Mr O ! Really enjoyed the PCM repair video also. Another great repair tech in another trade that relates to auto fixes. Dam good stuff !!

Oh, we love us some jubk yard. Thanks Eric. :-)

wouldn't be an SMA video without a random "CHEVY THUNDER!"... =) great video as always

Thanks for taking us to Wilberts again.

I learned something new today. Never saw a "Jumper" in a relay. Good ole Wilber's auto/truck land. Good one Mr. O.

Must have used that relay in another application. Replaced it with the shunt in order to use the same fuse box. Another mechanic who did not understand put a relay in place of the shunt and compounded the problem.

If you can do it, the neighbor can mow the lawn while you do!

I'm astounded how you can troubleshoot while yakking the whole time. I get totally locked up when doing that, I almost forget to breathe. I experience mental and cognitive stalls where I'll freeze in the middle of the sentence or similar. But then again I see you're great in troubleshooting, and I'm not too shabby myself either. Highly interesting. It seems that human mind has several approaches to this kind of thing.

Eric you have the gift of circuit plumbing in your brain. Nice find and discovery. I wonder if + or - voltage hit the control wire with the wrong relay plugged in?

That parts yard is a gem. Treasure it.

20 yr Hyundai tech here. I retired Hyundai and went independent so I’m going off memory. That generation Sonata was the most expensive to fix in my opinion but always kept running. I do remember A/T relay faults happening a lot. I may be saying that I remember replacing that relay a few times.

Wilberts! Love that junk yard amazing! My junk yard I use is so disgusting it’s a obstacle course! Can’t even move around in it and so unorganized! Great investigation Big O’! Your a cool dude!

I love it when you go to pick n pull. Great job as always.

Just watched L1a working on this board. Can’t wait to see fellow KZread shop helping SMA!

Always a good day with a trip to Wilbert’s, we have two in my area and you’re right need something it’s the place to go, unless you needs a door mirror, couldn’t find a good one there.

Ohhhhh yeah another wilberts field trip love it !!!!

You’re the best. Love going along to Wilberts. Aaron from Canada

Awesome. Love seeing your diagnostic process.

Impressive thought & reasoning process. Allways informative.

Eric that was awesome. I was hollering every you told us. Understood your Whole process. Dr. 0 Your my favorite Can't wait till you hit a million subs. I'm 1 of your first subs. Love the tow truck vid with your brother.

Amazing how you do what you do!!!! Thanks for being here!!!

Upullandpay Denver is where I go for a fun treasure hunt. One of my favorite things to do on a nice day!

Trip to Wilbert's first thing in the morning, great way to start a day!

Great idea having the rock surface so much cleaner than the Pick-A-Part yards made of dirt here in So Cal. Unless you drop something small and it disappears.

Amazing and amusing both at the same time. Eric, I wish there were a few talented Mechanics like you where I live. You are number one.

Excellent video! You never fail to amaze with your diagnostic ability.

You're completely right that not all relays are really relays. Came across an alternator "relay" in a Mitsubishi Diamante, which was just a resistor inside the little case. Turns out it was a backup in parallel to the alternator light in the dash, which was connected to the exciter of the alternator, so the car will still charge, in case the bulb in the dash burns out. Pretty smart thinking on behalf of the engineers. 😉

Eric, that was so cool to watch and learn. As always, if you can do it, I can watch. Thanks so much for what you share.

Always a great video when we get a trip to Wilbert's!

South Main Auto Repair does it again, great job! My friend and I spent every weekend going to the scrapyard, you can learn a lot while there. Thanks for taking me down memory lane every visit to Wilbert's U-Pull it.

Eric is a master of his trade and a very good teacher of all things automotive repair.

Very good video. As usual you follow thru with the plan. Keep them coming.

The BEST VIDEO EVER! Great info Eric! LOVE THE CHANNEL!

Pick n' Pulls are awesome. Sadly here in Sweden, people don't treat the "junk" with respect. You'd not be happy to see how people get to the parts they need, they just tear through stuff until they reach what they need. Just ripping stuff apart, throwing stuff they don't need on the ground...I hate that. Yeah, you didn't need that bit, but SOMEONE else may! Plus it's someones property, dickhead. Sorry, rant over..

You just described our local yards. We have what is known as "Flippers" that will go with a shopping list for eBay. (In some cases they will use their cell phones to post parts as they are being removed.) They will buy up all the popular headlights, tail lights...pretty much any cheap part that they can resell for huge profits. And yeah, they rarely bring anything more then a set of bolt cutters, pry bars....and more cutters.

Thank you for all your videos, very intriguing. Also I m glad you opened that brown "relay" I have never seen that! Keep up the great work. I appreciate your time.

I wouldn't have guessed that was just a jumper!! 🤔 Excellent as always!

Love seeing the process. Thanks for sharing. In 2019 I bought wife a new 2017 Elantra "Limited Ultimate" off showroom floor. It was discounted 8k because it was 2 years old. It had 25 miles on it. I bought it for 21k +dealer BS) 25K out the door with a full 10 year warranty ( covers electronics/navigation, fancy headlights, heated seats etc.) 4 years all ive done is change oil every 4-5k miles. GREAT CAR . 35-42 mpg with a Atkinson engine design. 6 speed auto. Port injection.

A shunt is always on. It allows the ECM to measure the current flowing through the shunt. The failure to detect the change in the voltage on the scan tool, demonstrates what the shunt does. Since there is not shunt in there, nothing is providing the data and that is why it is not changing on the scan tool. When Eric opened the shunt, at Wilbert's, though it looked as though the other two pins were inactive, they can nonetheless detect the current flow from the magnetic field that forms as the current _begins_ to flow. That shunt looks like it works to me, and will send a data signal to the ECM as the key is turned on. The two "unused" pins you see, are antennas that detect a change in current flow. If the current is AC then the shunt can monitor the current flow continuously. If it is DC then only when it changes can the current be measured.

Probably thinking of a ct (current transformer), which indeed only picks up a signal when the current changes. But you'd need a couple of coils around the wires your sensing. Doubt it can act as an antenna, way too much noise from the alternator usually.

@@shadetreemech290 No, actually that's not how this works at all. That's clearly not a current measuring shunt. This is very obviously a bypass for a feature not present in this particular car's powertrain. It's cheaper to do this sort of thing than have an entirely different wiring harness. Some other transmission available in that car would have a proper relay and appropriate PCM programming.

great diagnostic process as usual. I am sure you have your nemeses, but you always work the process and work the problem down and never rule out multiple solutions. I also like how you take a moment to make sure of the way the circuit is functioned. ground side vs positive side, key on vs key off or always on.. a very important thing to find early or you could chase your tail...
