Ford Fusion - ECM Coil Drivers Up In Smoke
ฝัง
- เผยแพร่เมื่อ 6 เม.ย. 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.
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."
"Oh Sweet, even better, this is the fun part of working on stuff after someone else. It's already missing all the bolts". 😂
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.
It's cool to see Eric O getting AMPed up at work.
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?
“Almost gave ya the shocker”….made me spit my beer out.🤣🤣🤣🤣🤣🤣🤣
"It is well with my soul" One of my favorite songs. Thanks for a flashback
I will look forward to Keith's video.
Amen!
I’m happy to see the “lean & stare” diagnostic technique is used even by the best mechanics.
Had me saying "Ruh Roh" for a minute, when I saw the smoke coming off the bulb! 😲 Great job on the diagnostics!
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 🤣🤣🤣
I miss when Keith used to post regular videos. Guy's a genius.
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.
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 !
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.
My thought was right from the get go that the wires were shorting together too but you proved that as wrong. Excellent diagnosis !
The fact you took this on after seeing all the previous amateur troubleshooting, is a testament to your character and skill level, Cheers
FET's go bang in mysterious ways
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.
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
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?
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
Great hymn "It is well with my soul," and the story behind it.
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.
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😅
27:53 brilliant test. Genius problem solver.
The only thing that could have made this video better is if you could do a Columbo accent! Great diag, Eric.
Not sure I totally understand the wire testing part if this video but it was a learn experience can't wait for part 2.
Great job isolating the wiring from the “brain box”, among everything else.
Almost got the Shocker!!!
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 ✌🏼
You are brilliant Eric!
Nice work
Great job Eric
Excellent video as always.
Great diagnostic video Eric!
Thank you SMA
Thanks for the video Eric.
Wow well done Eric.
Your thought process continues to be amzing.
Great diagnostic video! Learn something new every video.
Great Diag Mr O.
Thank you for the instructive video ❤
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.
It's good to see you enjoying a diagnostic job!!
Thanks Eric for the early morning enjoyment. You are truly a master at your craft.
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.
I have to say, you never cease to amaze me with your diagnostic work.
Another job well done
Good diagnosis! 😮
Very valuable information again So Awesome!!!!!
Absolutely positively excellent video!
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!
Great video, educational and interesting. Always love Eric’s style 😊
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.!
great video great process of diag!!
Great day for a South Main Auto mystery video!
Great to see you wearing your glasses on a more regular basis like I suggested! great you taken care of your eyes Eric
Nice work considering the multitester verification of the "wiring integrity" ... thorough to the nth degree .... good proof of concept !
Very good video Eric! you and everyone watching learned something! I just hope to remember this!
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!
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.
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!
Perfectly loved playing in the background. 💪💪💪 Love it
enjoy your videos here in Newcastle United Kingdom UK.
I was hoping for a vicarious trip to Wilberts. I always love those.
great video thanks for explaining and sharing
good post eric,, ty!!!!
Awesome job, I can definitely see how that could have been a big boo boo. Stay safe, and God bless
nice catch!
Normally controlled by high power switch called a Mosfet, these can fail open or short circuit.
Good job Mr O 👍
Oooo, this was a good one!
I wish I had your knowledge on car wiring in the moment ❤
Working on the antiques lately lol. Nice job
great catch...I'll look foreword to the vid...long time fan...
It’s amazing how the old memory bank works , watching your videos and I think you can join the club of people that can say “ I forgot more than you ever knew” or something like that. There is a saying but I don’t remember it exactly, lol. I’ve not seen this issue with Fords PCM coil drivers staying open but I have seen the injector drivers being open on Fords that causes flooded engines and some cases hydro-lock. Retired now so hopefully I won’t ever have to see this….unless on of my kids buy an old Ford
Awesome vid!!!
Great way to start the week!!
Hey, Eric, don't feel bad about the near miss. I would have got it wrong myself. A marvelous save!
Huzzah! For another educational, and entertaining video!
Eric O. breaking out the hymns..it is well because your knowledge has helped me fix my electrical issues.
I think that was a good lesson. Thanks
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 😂
Another great 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.
Excellent video.
You're the Best Eric
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 :)
That is interesting find
Morning Eric👍👍
"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.
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.
Great diagnosis hope it can run fine. A pain but a solution.
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.
whew, almost got the shocker...lol. Thx for the video!
Eric I am very familar with that song "it is well" 👍
Good video
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
