THANK YOU SO MUCH for the Bonus Video with the PCM change over. I was seriously curious. AND your ability to diagnose these days, is getting kinda scary. When the planet collapses, you are definitely welcome on my ship as Head Mechanic : )
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.
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 TH-cam.
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!
1975 C20 crew cab long bed 350/4speed. Gets lotsa looks now that it's ancient. I almost sold it to a coworker before I got sick. Sure glad I didn't let it go.
"Run down to the junkyard", here in Canada that is the dealer. Actually, we call them the KaBoom dealer, for their engines that dynamite at 75mph sending your Spyundai into a spin on an icy highway.
I worked on a sonata recently. Had a misfire and all the ignition coils had melted?/corroded into the manifold. I had to take all 4 out in pieces. Never seen or heard of that happening. Terrible car. But with new plugs, coils, TB cleaning, oil change, engine filter, she ran butter, I mean BUTTER, smooth lol. Customer was pumped. Paid me really well. I’m a cook, he’s a server at same place. I do this on my days off. LOVE fixing cars.
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. 🙂
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
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.
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.
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.
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 🙂
THANK YOU SO MUCH for the Bonus Video with the PCM change over. I was seriously curious. AND your ability to diagnose these days, is getting kinda scary. When the planet collapses, you are definitely welcome on my ship as Head Mechanic : )
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 !!
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).
Ya Know I've been doing electronics since 1980 avionics autopilot, instruments, navigation, calibrated O-scopes, factory electrical and appliances. and You are my go-to Guy. I tell anybody working on automotive to check you out fun, educational, determined and down to earth. won't ever forget the video where the power steering pump was affecting the fuel system, and then the other day on the chevy where the left rear shock was keeping it from starting. Thoroughly enjoy Your channel Keep up the Great Work
Eric, I love your vids. Not only are they hilarious, but they are informative. I learn a lot. There is always another way to do things. 30 years in the trade, also instructor. Your sayings, Ericisms are what we share as well.
I use some of that Eric O. Dictionary (as my fiancee would say) from time to time Whoa fella! Ope man down Ope there's yer (REAL?) Problem, lady -- not a sponsor
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.
Thanks Eric, I watch every video you put out, mostly on the job while fixing my own NY state rusted crap. I enjoy all of them and always gain alittle something from them. Thanks
Rainman Ray says never go by whatever diagnosis the owner provides as they are often wrong or haven’t properly diagnosed. He says do your own diagnosis based on what you observe. Also that owners who try to help by providing diagnosis info often just confuse and cause you to overlook things. I agree with Ray and want to commend you for going straight to the scan tool and diagram to try and diagnose.
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.
The way you efficiently and methodically diagnose issues, even simultaneous issues, is simply amazing. You would make a great instructor if that's something you're interested in.
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!
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 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.
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.
Great diagnosis, been in the trade for 50 plus years, now in Ontario there are not alot of you pick parts, mostly crush cars. Your salvage yard looks great.
My parents have a 2010 model year of this car with the same 2.4L. It has over 230,000mi on it and still being driven. Original engine and powertrain. No major issues other than routine maintenance/service. Back before Hyundai/Kia came out with the GDI engines in the 2011 and newer models with engine issues.
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.
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. 😉
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 video! I worked avionics for 38 years and it's difficult to explain to the family what's really involved in troubleshooting problems. This is car not an aircraft but same principle and a very good example of what separates the master tech from the guys just starting out.
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. You are as curious as I am. Relay that’s not a relay! Who knew?! I probably would have just tested the relay, not ripped it apart. Watch this channel continuously. Consistently interesting.
Define a SHUNT: provide (an electrical current) with a conductor joining two points of a circuit, through which more or less of the current may be diverted. "these components are designed to shunt electrical surges away from microcircuits" SMA, good find on the 2.4L. Canadians refer to Railroad Track Switches as "Shunts". The UK does also.
I think we need to chip in and order DR.O his first DR.O personally subscribed DR.O Lab coat with that SMA insignia!! Dude you kill it no matter what they bring you can fix it execution style!! Lord knows I don't want to see anymore cold or snow then we get here in the Big O, but I would move down the street from you just to have you as my auto DR!! You and Mrs.O rock!!!
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?
I am buying a 2009 Kia for my granddaughter that has this same 2.4, 4 cyl. motor. The car just passed the latest state inspection and no codes were present, but I will definitely keep this video in mind. thanks, SMA....good timing..!!
@@2nickles647 Yep, I am familiar with the Kias and the Hyundais that had a motor manufacturing problem and had to recall a bunch of them. The motors that have the GDI injection system are also not very good, at least not for very long. Having the fuel injected under the intake valve and not on top where fuel injectors are usually placed to keep the carbon from building up on top of the valve didn't work out very well. Then, and perhaps an even more important factor in so many of these motors, not just Kia and Hyundai but many other motors too, was the idea that now you could drive for 8,000-10,000 miles before doing an oil/filter change. That fallacy has also been shown to be harmful to the longevity of motors. This particular Kia Rondo ( yep, don't see many of these around, the market just didn't want this particular style ) has a very impressive maintenance record and wasn't part of the big recall. The two owners did a great job: Oil/filter changes every 3-4,000 miles...nice...so important...front & rear brake pads changed before they wore out, throttle body cleaned, brake fluid flushed, alignment when needed, and other stuff. At 168,000, it is in great shape, and as long as granddaughter can get 2-3 years out of it, mostly to & from work, it will be a good car. I paid a little over $4,000, and in the Virginia Beach area, and for that price range ( no...couldn't afford a $6-8000 base price...one does with what one has...), and with the great maintenance record, it is a good deal.
I bought a used Ford Exploder a few years ago as a temporary vehicle, just to last for a few months at best. It had some really strange electrical issues, and in trying to pin them down we noticed that all the relays were exactly the same. Upon looking into it further, we saw that two of them were supposed to a different number, so off to the local pull and save, found the two relays needed and all of the electrical issues went away! Ran it for about 6 months until the situation changed in my favor for a different vehicle and got rid of that one (it had the engine with known exhaust manifold leaks that required almost a total top end repair)
I've been an ASE mechanic for over 30 years and retired from the game a year and a half ago yet every time I watch your videos I get something out of them. Now I know about that relay/jumper on the Korean cars (Kia and Hyundi). Thanks brother...🤓

Wow, an early one, my coffee isn't even ready yet. That was a good one. Even a trip to Wilberts.
Wilbert's the most famous junk yard in the world!
Yes i know it and am 5000miles away so a bit much to travel Eric is the master detective in the world as well.
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.

Eric I’ve decided the only way I could continue to drive my older Duramax van would be to move close to your shop!
Eric as always your logic and deductive reasoning gets the job done.
A trip to the yard. I know it's going to be a good video even before watching. !!!!
You can do diagnostics better than 99% of techs out there. Navigating electronics is not easy. Great video
Probably 99.9% 😂
I worked on a sonata recently. Had a misfire and all the ignition coils had melted?/corroded into the manifold. I had to take all 4 out in pieces. Never seen or heard of that happening. Terrible car.

A trip to Wilberts and the lawnmower guy. My day is complete :)
Eric, i love the way you get excited once the so called light comes on! And bobs your uncle!
If you can do it, the neighbor can mow the lawn while you do!
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.
One of the advantages of living in South Alabama. It doesn’t snow . And our cars don’t rust out
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.

Highly interesting. It seems that human mind has several approaches to this kind of thing.
Sometimes talking out the problem helps me to rationalize whats going on. It makes me slow down and think, since my brain out runs my mouth.
Awesome diag. Never seen a “relay” that is just a jumper terminal
What he is basically doing is saying out loud what he's thinking... that's why these are so good, you can follow his train of thoughts step by step.
He has the gift of gab.
I am also like you.
No TH-cam for me.
That’s the difference between rookie level and experienced level.

'Also have an '01 GMC 2500 Silverado 4WD in AZ, so appreciate those vids.
Great video!
I worked avionics for 38 years and it's difficult to explain to the family what's really involved in troubleshooting problems. This is car not an aircraft but same principle and a very good example of what separates the master tech from the guys just starting out.
just retired out of 40 years avionics myself ! cool video
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.
Always a great video when we get a trip to Wilbert's!
Trip to Wilbert's first thing in the morning, great way to start a day!
Amazing. You are as curious as I am. Relay that’s not a relay! Who knew?! I probably would have just tested the relay, not ripped it apart. Watch this channel continuously. Consistently interesting.
Road trip to the salvage yard is a fav
Great Job Eric, very interesting with that "Dummy" relay !!
Define a SHUNT: provide (an electrical current) with a conductor joining two points of a circuit, through which more or less of the current may be diverted.
"these components are designed to shunt electrical surges away from microcircuits" SMA, good find on the 2.4L. Canadians refer to Railroad Track Switches as "Shunts". The UK does also.
Drove out to wilberts in Rochester and was not disappointed! So much better than the junk yards in Massachusetts
I think we need to chip in and order DR.O his first DR.O personally subscribed DR.O Lab coat with that SMA insignia!! Dude you kill it no matter what they bring you can fix it execution style!! Lord knows I don't want to see anymore cold or snow then we get here in the Big O, but I would move down the street from you just to have you as my auto DR!! You and Mrs.O rock!!!
Awesome. Love seeing your diagnostic process.
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?
Over my head but the way you explain it makes it enjoyable to watch and of course learn something
I am buying a 2009 Kia for my granddaughter that has this same 2.4, 4 cyl. motor. The car just passed the latest state inspection and no codes were present, but I will definitely keep this video in mind. thanks, SMA....good timing..!!
My daughter had a Kia. Motor ended up burning oil. Factory problem. Traded it on a Toyota. Glad it's gone. Danks for the memories 😅
@@2nickles647 Yep, I am familiar with the Kias and the Hyundais that had a motor manufacturing problem and had to recall a bunch of them. The motors that have the GDI injection system are also not very good, at least not for very long. Having the fuel injected under the intake valve and not on top where fuel injectors are usually placed to keep the carbon from building up on top of the valve didn't work out very well.
Then, and perhaps an even more important factor in so many of these motors, not just Kia and Hyundai but many other motors too, was the idea that now you could drive for 8,000-10,000 miles before doing an oil/filter change. That fallacy has also been shown to be harmful to the longevity of motors.
This particular Kia Rondo ( yep, don't see many of these around, the market just didn't want this particular style ) has a very impressive maintenance record and wasn't part of the big recall. The two owners did a great job: Oil/filter changes every 3-4,000 miles...nice...so important...front & rear brake pads changed before they wore out, throttle body cleaned, brake fluid flushed, alignment when needed, and other stuff.
At 168,000, it is in great shape, and as long as granddaughter can get 2-3 years out of it, mostly to & from work, it will be a good car. I paid a little over $4,000, and in the Virginia Beach area, and for that price range ( no...couldn't afford a $6-8000 base price...one does with what one has...), and with the great maintenance record, it is a good deal.
Well done sir, love to see you diagnose and repair!
The BEST VIDEO EVER! Great info Eric! LOVE THE CHANNEL!
at 5:45 on the diagram of the control relay it shows a direct pass out of relay,no control,just a pass through,great diag as usual.
Another reason why you the Best youtube tech out there!! Excellent job as always, keep the videos coming 😂
I bought a used Ford Exploder a few years ago as a temporary vehicle, just to last for a few months at best. It had some really strange electrical issues, and in trying to pin them down we noticed that all the relays were exactly the same. Upon looking into it further, we saw that two of them were supposed to a different number, so off to the local pull and save, found the two relays needed and all of the electrical issues went away! Ran it for about 6 months until the situation changed in my favor for a different vehicle and got rid of that one (it had the engine with known exhaust manifold leaks that required almost a total top end repair)
I've been an ASE mechanic for over 30 years and retired from the game a year and a half ago yet every time I watch your videos I get something out of them. Now I know about that relay/jumper on the Korean cars (Kia and Hyundi). Thanks brother...🤓
I like that kind of diagnose, was so satisfying.
I love when we take trips to wilberts!!! Awesome video Eric !!! Nice trouble shooting as always always enjoy it
