Ford Fusion - ECM Coil Drivers Up In Smoke
HTML-код
- Опубликовано: 6 апр 2024
- In this video I have a look at a customers Ford Fusion with the big 3.0 that will not run. The car was already looked at by the owner and he thinks it needs an ECM and we just have to make sure that is the case. It has a strange failure that side tracks me for a moment but we get it figured out in the end.
-Enjoy!

Where’s part 2?😝🤣
lol people actually call your shop for that?
I’m definitely watching this on 47/24…..
If all goes well, most will be blind on Tuesday after looking into the eclipse on Monday? So part two will be for naught?
"call the shop"...seriously, over a YT video lol
4 years of college, graduating as a master ASE cert mechanic. The Instructors regularly play your videos in their presentations for all the students. I, now happily have my own mobile auto repair business, and continue to watch all of your videos in my free time. My favorites are the electrical diagnostics. Amazing how much you know, how well you explain, and how great your videos are. Your nickname at my college is “South Main Wizard”. LOL. Anyway, everyone loves what you do, keep it up! We appreciate it.
A guy has a million dollars in test equipment and proves the trouble with a light bulb.
Just remember folks, it’s the tech, not the test box. Great job.
Test light is the number 1 electrical diag tool
As a tech the old school tests still work your best tool is you eyes and ears it's called kiss keep it simple stupid to many techs first thing get out the scope and use it for everything
Just remember...if he can do it, you can do it.
it's not the test gear. it's the knowledge on what the results mean.
Years ago, Eric, Ivan and Paul "Scanner" Danner attended an "Eric-the-Car-Guy" meetup. They travelled in Paul's motorhome and talked about the logistics of going to the meetup from the motorhome. Ivan speaks up and says they have about 100 test lights between them. Priceless.
I don’t know how you find the time to run a business, work the shop, AND put out your videos but I sure appreciate them. Thank you!
His wife does all the paperwork and invoicing, that's half the job! 😂
Mr O. It has been my privilege to employ and work beside some incredible technicians over 40 years. The ones who were the best ALWAYS suspected themselves when fault finding, consistently checking input/outputs etc. and being totally transparent when explaining themselves. Just like you, so don't be too hard on yourself as you have completed a first rate investigation. You also smiled the whole time.
"Oh Sweet, even better, this is the fun part of working on stuff after someone else. It's already missing all the bolts". 😂
The best reason to watch an SMA video is the last spoken sentence, "Remember viewers, if I can do it, you can do it." This always comes right after we have watched a Grand Master Mechanic perform an act of Super Genius. Hearing this feels to me, like watching the interviews after an NBA Championship game, and Seth Curry says, "Remember viewers, if I can do it, you can do it." Yeah. Right. This SMA video, like many SMA videos, features a car that has been worked on by another professional mechanic, who, finding themselves stumped, sends the car to Eric O, while saying, "Remember viewers, if I can't do it, send it to Eric O."
Your ability to find wiring issues is completely off the charts. You make it look easy, and it definitely is not an easy task in any form. It's a real pleasure to watch you troubleshoot and find issues.
Thanks for fixing my car, Eric. It's going on the road tomorrow!
Glad to help and glad it turned out good for you in the end!
When were the spark plugs replaced?
Coffee, Eric O., and wires. What more does anyone need?! BRILLIANT!
Mrs. O!
that’s funny cause ghat how I started my day this morning, coffee and auto diag lol😂
My pipe and an English blend tobacco.
It's cool to see Eric O getting AMPed up at work.
"It is well with my soul" One of my favorite songs. Thanks for a flashback
I will look forward to Keith's video.
Amen!
Had me saying "Ruh Roh" for a minute, when I saw the smoke coming off the bulb! 😲 Great job on the diagnostics!
Wow,a 2008 Ford in the PRNY?....That thing should be in a museum!
I think you're in forbs richest Number 1😂😂😂😂😂😂😂😂😂
With rocker panels!
Heck. All the ones I see here in Indiana are practically crumbling to pieces. My coworker has one and it's so rotted out it's sagging in the middle.
Better than the Fords they make today. That's why people still drive these.
It will be after next winter ✌🏼
Eric: "I went out to my truck and got my glasses.", then proceeds to hang them around his neck and not use them... 🤣
Better than leaving them on the seat and breaking them. Ask me.
He put them on when he looks at the paper diagram.
Maybe he can’t see them ….
Been there done that every day... You just wait it's coming right at you.
I read your comment before I watched the video, so I was watching for it......yeah.... he did use the glasses.......then hung them around his neck.
That door bell scares the crap out of me,every time! 😂😁😅
Gas customer arrived right? Well back in the 50s/ 60s.
funnie!
It sends my dog in to anxiety tremors.
Bloody right that scares the poo poo out of me. Mrs o gunna have to do sumfin about that, it's not good
I’m happy to see the “lean & stare” diagnostic technique is used even by the best mechanics.
Great hymn "It is well with my soul," and the story behind it.
From the day I started watching your videos,one thing about you I love is your Honesty about mistakes u make or could have made, because we all learn from you as to what can happen to us, AMEN😅
I miss when Keith used to post regular videos. Guy's a genius.
An indicator that the coil driver circuit parts inside PCM are probably replaceable is the fact that Ford has the PCMs in stock. Since you know that Ford is NOT manufacturing new 2008 parts of any kind, Ford must be opening up core-return PCMs, replacing the Coil Driver parts, sealing it back up and reselling it. What that means is you can probably get your PCM repair guy to do the same fix at a fraction of OEM replacement cost. I don't remember the name of the tech company that Eric O uses for PCM repairs. Anyone else remember?
Just had one of these towed in. Turned the key on to scan for codes and two of the coils popped just sitting there. I was super excited since I had just watched this video and could now play along at home :)
My thought was right from the get go that the wires were shorting together too but you proved that as wrong. Excellent diagnosis !
We have a 2012 Fusion and it has been an outstanding car. We have 130+ thousand on it. Wouldn’t even look at anything else but we are getting up there in years a it’s like crawling in and out of a go cart being so low to the ground. Even with that we won’t spend the money on the rip off vehicles they have on the lots !
Fantastic Mr O. Loved that you were excited to solve the puzzle and taking us on a joy ride one of the best i have viewed. Cannot wait for Numero Doz.!
I always make a bucket of popcorn and wear my South Main Auto T shirt when I tune in for the most recent video. Eric does NOT disappoint!
Great job isolating the wiring from the “brain box”, among everything else.
Almost got the Shocker!!!
Eric, this one brings back memories when I worked at a dealership. When diagnosing an ECM that went bad, that the drivers failed I would check the resistance of all the coils in the vehicle. Ignition, solenoids and relays. To make sure they were not shorted or had too low resistance. Thank you for your videos and great work. Have an awesome day!
There is a TSB from ford on the 3.0 engines in the Escapes, Fusions, Mariner, and Mazda Tribute, for the coils failing and knocking out the coil driver for that bank in the PCM, and the TSB states to replace all 6 coils, spark plugs, and the PCM.
Perfectly loved playing in the background. 💪💪💪 Love it
Thanks Eric for the early morning enjoyment. You are truly a master at your craft.
Your thought process continues to be amzing.
Good catch Eric!
Something similar happens to NA Miata's. I bought mine as a repo from a bank. Their customer told them it had a blown head gasket and they could take it. First thing I did was check no water in coolant and no coolant in the water. Next I traced it back to one fuel injector that was always on (dumping unburnt fuel into the cat and making large clouds of white smoke which caused former owner to think it was a blown head gasket). Turns out that the capacitors in the old ECM's are known to fail and burst. When they burst, they leak conductive or corrosive chemicals down the board and cause odd behavior depending on where they leaked. I was lucky (my car is a one year only California Emissions NA 1.6 version) and found a used ECM on Ebay. I also had my electrical engineer cousin look at the old ECM. He ended up replacing the blown capacitors and cleaning the traces in the damaged area. Now I have two working ECM's.
I have to say, you never cease to amaze me with your diagnostic work.
I like to play a game when I watch an SMA video. Its called " What is Josh doing?" Only to know what's going on in the other bay, Lol. Thanks for sharing, Eric. Have learned so much from the " If i can do it, you can do it!", mentality.
Very good video Eric! you and everyone watching learned something! I just hope to remember this!
The fact you took this on after seeing all the previous amateur troubleshooting, is a testament to your character and skill level, Cheers
Not sure I totally understand the wire testing part if this video but it was a learn experience can't wait for part 2.
You scared me dude . I thought for sure you let out the magic smoke till you said it was some crap on the bulb. 😂 great video as always eric
I had an 08 with the 3.0. Had intermittent misfire on cylinder 3 that I could not track down. Good compression, new plugs, coils… the whole bit. The next step for me was the ecm, but with200k, we ended up trading it in. Otherwise great car.
I had an 08 with the 3.0 for ten years. I loved that car. Very reliable.
I had an 08 Milan with 4 cyl. manual trans, best car I ever had!
I was hoping for a vicarious trip to Wilberts. I always love those.
I have been watching Eric for many years now. I love these raw diagnostics videos because he starts on a theory and then works the problem and sometimes proves his own theory wrong but gracefully.
Eric O. breaking out the hymns..it is well because your knowledge has helped me fix my electrical issues.
Nice work considering the multitester verification of the "wiring integrity" ... thorough to the nth degree .... good proof of concept !
Love, LOVE, **LOVE** this channel! I have *never* watched one of your videos and not learned something. Every single one has taught me *something.* Who'da thunk a computer could fail like this? Looking forward to part 2, and to Keith's video when that gets done.
That’s a very familiar pause about 20 minutes in when you say, “Yes this is very useful information” and then pause.
Now, what the hell does it exactly mean, it what was going on in my head 🤣🤣🤣
It's good to remember - you got this car second hand. The mystery could have been induced. Great troubleshooting. Looking forward to Part 2. Thanks
Absolutely positively excellent video!
Hey, Eric, don't feel bad about the near miss. I would have got it wrong myself. A marvelous save!
It's good to see you enjoying a diagnostic job!!
Awesome job, I can definitely see how that could have been a big boo boo. Stay safe, and God bless
You are brilliant Eric!
Great diagnostic video! Learn something new every video.
Great diagnosis hope it can run fine. A pain but a solution.
Eric is one smart dude! I'm an electrical engineer who also happens to work on my own cars. I have learned a ton from Eric.
Great to see you wearing your glasses on a more regular basis like I suggested! great you taken care of your eyes Eric
Great day for a South Main Auto mystery video!
enjoy your videos here in Newcastle United Kingdom UK.
You go from a 1995 Geo Prism to a 2007 Ford Fusion. Word is Out that South Main Auto LLC has a Super Talented Team that consistently Overdelivers. 👍🙏
27:53 brilliant test. Genius problem solver.
My experience with OTC is GREAT. I really like their customer support team...
I wish I had your knowledge on car wiring in the moment ❤
Great diagnostic video Eric!
Great video, educational and interesting. Always love Eric’s style 😊
Great job Eric
I’ve crystallized my knowledge more and more watching our dear sir Mr. Eric O. Yet I find I’m helping A LOT of co workers. I work at a restaurant and after work I’m in the parking lot looking at multiple cars. All “favors”. No $. It’s getting to me, quite quick, but I like to help people. I think. Lol But ya know.
Very valuable information again So Awesome!!!!!
Thanks for the video Eric.
“Almost gave ya the shocker”….made me spit my beer out.🤣🤣🤣🤣🤣🤣🤣
Normally controlled by high power switch called a Mosfet, these can fail open or short circuit.
Good job Mr O 👍
I made that connection as soon as you got power on both sides of the coil wire. Nice 👍
Another great electrical debug video showing not only great circuit awareness but good understanding of magic boxes and their pitfalls!
I’m not sure if I watch these videos for the learning aspect or the comedy. I crack up watching this dude it’s a funny comment here and there 😂😂😂😂
Wow well done Eric.
Superb, Mr. Obrochta. It would only have been a booboo if the wires were indeed shorted and you had replaced the computer...that would been the end of your spirit life. One will have gone to the woods in his mind and begun to sing the death song, lest he bravely forge ahead with the 'why' question...a nightmare scenario for a guy like me. The lesson to learn here is to attempt to isolate why the ECM failed...including proving that the wiring harness is intact so did not short it's drivers...hmmm, attempting to discover why a module fails before replacing it means looking for any shorts that could have done it in. Now where have we heard that? Call me knocklehead.
FET's go bang in mysterious ways
Your right about disconnecting the PCM connector and verifying there's no short between the control wires for the primary side of the ign coils. Except for engine fires and accidents that burned wiring, I never saw that!
Free tip Sunday!
Good one Mr. O!
The only thing that could have made this video better is if you could do a Columbo accent! Great diag, Eric.
Working on the antiques lately lol. Nice job
Nice work
"There's all kinds of clues around here." - Eric O. Who knew I'd be watching a Hardy Boys episode when I clicked the link.
"I don't know how I've never made this connection" (28:29) I had to laugh (you didn't the PCM did). I like how concerned you are that your original approach may have lead you astray, shows you are always honing your skills.
Great hymn reference, Eric!😊
Pretty sure you can do it, also pretty sure I can't do it! Always a good day with SMA video
I am guessing the driver is probably an IC package, if it saw over current it usually takes out the package and the chip many time shorts to VCC or 12 volts. I worked on a couple of GM ECM's back in the day for the "quad driver" failure and it was a 4 section device. My friend took out 3 new ECM's before I helped him find a shorted EVAP solenoid. The IC had a hole blown in the front of it. I think on newer coil package designs the ECM doesn't handle current on the switch side of the coil, the ECM sends a low level signal to a power FET in the coil thus protecting the ECM from this type of failure.
Thank you for the instructive video ❤
Excellent video as always.
Thank you SMA
Hehe. Brings back memories...the most forward cylinder is #1??? That is usually but, not always true on Ford. The right side front is ALWAYS #1 on Ford. I can only think of one example: Super Duty V8s. 401,477,534. I'm old, so yea, I worked on those back in the day. The left bank is forward of the right on those beasts. As a young mechanic, I was stumped as to why I couldn't one started after a distributor replacement...All I got was nuclear backfires(have fire extinguisher ready). I assumed the most forward cylinder was #1. I was wrong. The most forward cylinder means nothing on Ford engines.
Great diagnostic video, as always - very helpful to hear you think, Eric. Thanks for also asking Keith at L1 Auto Diagnostics to make a video about what happens in the black box (computer). That should be very educational!
Good diagnosis! 😮
Impressive. You’re like the Mr. Spock of auto repair.
Had this happen to me on a test drive and I had to limp it back on 2 cylinders, holy shit was that a fun drive 😂
I need this channel I worked on vehicles a long time but never learned electronics at all it definitely hurt me
I couldn't help but notice the music in the background.... 👍
whew, almost got the shocker...lol. Thx for the video!
Another feather. In your hat. Must be. Magic. How. You. Bring. All your. Experience. To. Pin point. The. Problem. Thanks again
Yes,Yes,,, If I could did it,,, You can did it. And look,, Eric showed a proper how. Fun working on cars. seem to be the the one that gets to figure out the problem after others have had their turn at it. A fuse eating car, some damage happens when the repair is suppose to happen.
Great Diag Mr O.
That was quite the roller coaster of steps and results. Great job Ford, turning what should be a simple trouble code into a 40+ minute troubleshooting masterclass. Huzzah!
