Experience is what's it's all about . What you learned there , you won't forget and will be ahead of others that don't have it. Your tenacity was awesome, as you didn't give up, frustrated yes, but kept on. You have a great analytical mind blessed with the ever important common sense. This was a very enjoyable series to watch and look forward to future videos. Big fan of yours, eric o's and scanner danner's videos. Thanks !
No computer, no relay, no fuses or even a throttle body was fitted to this vehicle. A lessor mechanic might have thrown all these parts at the car without any success. Someone commented that a load pro would have found this. I doubt it very much. The real problem is the customer understands the the hours of diagnosing time and the many thousands of dollars invested in state of the art equipment to find the problem that resulted in a simple fix. Great job Ivan. Persistence paid off
Actually a relay and throttle body had already been replaced by the owner. Good thing he stopped there and called me to look at it to prevent any further parts cannon accidents haha
Awesome diagnosis Ivan. A case study like this is what makes diagnostics so great. if you're ever stumped like this again, ask yourself "what would scotty kilmer do". he's a diagnostic guru and such an expert with lab scopes and electronics as a whole.
Beautiful. Most technicians would have probably tapped out two videos ago and whipped out the parts cannon. I honestly wouldn't blame them. This shows the value of having the right tools and enough persistence to keep trying different things. You're the kind of person customers would want to have solving tricky problems. As an aspiring tech, your videos are very useful as they open avenues of diagnoses I would have never otherwise considered. Great work!
One of your best!! I agree with all the other commenters that "a lesser diagnostician" would have given up OR put in many unneeded parts, or both. The other thing that is REALLY cool, and is a very valuable "teachable moment" (or "teachable several hours") for the rest of us is that even the best (that would be you) can get temporarily "stumped" by a one in a million problem. The key is that you STUCK WITH IT, and just kept narrowing and narrowing the problem down. As you and some commenters have said, it really shows the value of having a 4 channel scope that cost several thousand dollars. Thanks for posting this one, it is very encouraging to us lesser mortals. -Doug
Doug, thank you for the motivational comment! I am too stubborn to give up on weird problems like this, even though so many hours are needed to finally nail the problem down. I see it as an investment in education :)
I work for Subaru in Lafayette, IN and this is what is called a soft set connection! It could of been that way right out of the factory and just took this long to work its way out!! Great video Ivan!!
An expression I used when I was troubleshooting computer network problems was "Look for the simple stuff first". A good cliffhanger makes life interesting. Thanks, Ivan!
Kudos your a well skilled mechanic that actually diagnose the problem instead just throwing parts at it and still not find problem as this was electrical problem and very simple one lol----Great work as always
So cool Ivan. What is most amazing to me is that the loose connector only caused one problem! Hard to believe. Well done sir, well done and thanks for taking us along.
Awesome work. This looks like a typical factory build mistake that took years to show up over plug not installed properly. Usually the problems show up a few hundred miles or with in of days when the the customer first get the car. I have seen many issues caused from a simple plug not connected or not properly pushed in from the factory creating hours of troubleshooting . After years of chasing this, I go right to the connections and check this first. Electric does not like resistance and connectors or a factory worker that did not plug in or push a plug in all the way......Great videos.
Well done Ivan. You earned a couple of more gray hairs off of that one. It's hard enough to try to diagnose a car that doesn't want to be fixed, much less trying not to cuss the whole time while trying to do so. You kept your head and relied on your experience to get you thru. Good job. Now go take a long mtn bike ride with Eric to go clear your mind. :)
Celebration!!! Way to go. Thanks for the entire three part series. I like the things that you have problems with as well as the things that you repair.
Other places would have put the parts cannon to use! Problems like this one take time to find and I think you've done great! Don't forget, this WAS an intermittent!..The curse of the automotive industry! GREAT JOB.....GREAT VIDEOS! Keep up the good work!
Unreal!!! I never would've guessed that in a billion years! EXCELLENT case study!! What sucks with stuff like that is telling the customer you need to bill them for, say, 5 hours diagnostic time, and the fix was "plugging in a loose plug". They tend to get wide-eyed when you drop that in their lap. Nobody realizes just how much work it is to find things like this on modern cars - even WITH the proper equipment, knowledge, & skills! Goes to show how complicated these cars have become. I think my next "new" car will have points ignition .... :D
Electricity can do some strange things! My theory is, since the pins in the plug were just lightly touching, just the temperature difference between a cold engine and a hot engine would cause enough expansion to complete the connection when warm, and separate it by contraction when cold.
Man what a conclusion! And here I was ready to give up after wrestling with stuck electrical connectors for 20 minutes today trying to diagnose a bad fan.
Likely it wasn't fully plugged in for the duration. All it takes is just the right pot hole and it'll back out enough to cause problems. And Congrats!! You just did the Ford Approved "Wiggle Test" for the EEC-IV system!!! And it worked on a Subaru!
Good job !!, it's a great feeling to finally get to the cause of the problem.This case study brought back memories, thanks for doing these videos Ivan.
I think you said in Pt 1 that this problem plagued the previous owner. It wouldn't be surprising to me if it came from the factory like that and given how intermittent @~1x/day it took years for surface oxides to build up on the connectors enough for it to be reproducible. I fixed a MIDI synth once that had unsoldered power supply wires resting in the plated holes and it had worked flawlessly for years before it got flaky. Great find.
Nice, nice work Ivan ..you rocked this bad boy out man..thank you for this diag lesson.. This one most definitely had me scratching my head at first..God bless you brother
That blew my mind. I had to watch part 2 again to keep it straight. Ivan, you've earned a scotch on the rocks!! This would've drove Eric NUTS! Great job!
Dam this is so intimidating to me. I got this code and the fact that it could be so many different things and end up requiring this level of knowledge and expertise to track down is really getting me worried. I'm hoping my issue is somehow easier to track down. Overall though I hope to be at your level of expertise one day. Great vid. Thanks for documenting.
My gosh, what an odd problem! I don't think there's even a chance that connector vibrated its way out, so either someone was in there, or it wasn't assembled quite right from the factory. Given that a relay was replaced, and someone else seems to have chased this problem already, I sort of sway towards someone having already been in there, but who knows! Awesome series, Ivan! Persistence pays off! :D
Having worked on pinballs for many years with intermittent faults we always checked fuses then connectors .the only thing you dint do is pull the connector right off inspected and plugged it back on , just the re-mating of the terminals sometimes helps .
nice work Ivan , as usual I knew from the part 1 that you are the man to fix this kind of problem , and you did it , keep the good work and this kind of videos, thank you for sharing
Great work, Ivan. I was guessing a rubbed wire somewhere between the relay and the computer since you had previously ruled out the feed wire and the fuse since the fuse was powering the other items with no apparent problems. Since you were moving around the relay box and the computer that left only the wire in between. What's interesting is that you said the fuse feeds the other relays but it actually feeds them on different wires coming out of the fuse box. Subaru's diagrams are a bit different, too, so that doesn't help, either.
Damn Dude, i don't know how much you charge your customers? But i'd say from your equipment and diag skills, your worth at least $200.00 an hour.. You are certainly building a very strong reputation for getting electronic issue's cured; Great work :-)
Nice diagnosis & find Ivan. Good catch with the faulty backprobe, you could have been chasing a ghost! If it didn't set it on startup it had to be setting it hitting bumps also. After it didn't fail on load testing it pointed towards a contact issue or load detection circuit in the PCM & the ole harness shake test worked. Did you ever find out if someone was working in that area. Good series!!
Fantastic work , almost got you , but you did not give up ! That's what I'm talking about...nice work dude..and you did it without your slippers on..lol
Awesome, you found the problem at last. I really like that you are persistent and don't give up easily. And let us learn from you. I have a cheap 2 channel Pico, and love it so far. But I'm no pro. Greetings from Norway :-)
A better and much cheaper tool for diagnosing intermittent is any old car speaker in series with a tail-light bulb. You hang the speaker and light across the circuit you want to monitor and then you can go wiggle things and you just listen for clicks and scrunches. With an occasional glance at the taillight to see if the juice is flowing. No scope, no eyeballs tied up, dirt cheap and very effective.
If in a hury I would first do wiggle test. But this way deffinitelly better for experience and keep in shape. But somethimes in a busy shop you want to move to another vehicle as quick as posible. Greetings from Serbia.
Makes you wanna beat some little Japanese dude with a hammer. Awesome find. Hope that paid well for all the loss of sleep. That would have kept me awake for days.
Way to be persistent! It paid off. Cool video and diagnosis. Love the pico (which one is it?). I'm curious what advantages the Verus has over it other than being more portable.
Well done! In vid 2, you pulled the relay at about 9 mins, and same code 2102 set. That should tell you right away that you are missing some sort of feed at some point or another, regardless of all of your load testing. I'm really glad you decided to go to the box. I was thinking about rodent damage there myself, but you found a bad connection of a different sort! I fully agree that w/o a scope that has a high live update ability, you would've been firing the cannon. Now, my only question to you, is how to charge for all the time involved? ;)
This video is awesome and shows how to properly diagnose and eliminate possible causes. But I'm wondering, if someone was in there already and the owner already had the relay and throttle body replaced.... were one of those bad initially and this just happened to create a new but same problem. Either way great video and now I've got some digging to do on my new to me 05 legacy wagon with the same code.
Excellent work. You were not lost, you were just in the forest, but you kept walking until you found the problem. Good job keep going. Since you are much more up to date than I am, what brand and model of laptop do you have to match the Pico scope.
Fantastic find there Ivan, you have a very patient, persistent nature. Not too many would have found that. Can I ask how many hours that owed you, and how many you charged?
I have the same problem. I changed the wires from the throttle to the pcm. #17 and 14 which go directly to the pcm. I just now checked that 30 amp fuse. It looked ok. Hopefully that’s the issue. I’ll push it in again and see what happens. Thanks.
Great that you found the fault but what is really amazing was that the fault was reproducible. Had the fault been intermittent then this might have provided a bit more of clue about intermittent electrical continuity. I like the scope but a detailed .visual inspection and wiggle test first can sometimes be a time saver.
Hindsight is always 20/20...the wiggle test can get you in trouble when you accidentally fix the problem itself, which I was trying to avoid. It's definitely a fine line, but yes, I should have gone for the wiggle test a bit sooner in the process :)
+motoYam82 I'm old school (carbs, push rods, distributor shaft, vacuum advance timing) and so my approach is very much still push, pull and examine :-)
How does the problem showing up on a cold first start of the morning fit in here? Would how and where the car was sitting play any part in that? Parking on a incline driveway causing the connecting to pull apart?
My brains in limp mode right now. After watching this. I have those same codes on my toyota corolla 2005. And now after watching this i dont know what to look for .
Great work, man. You know, you really could have used the load pro leads to tie your camera to the hood prop, since you forgot your tripod. Just a thought...

I like this guy already ☝
Actually a relay and throttle body had already been replaced by the owner. Good thing he stopped there and called me to look at it to prevent any further parts cannon accidents haha
@@PineHollowAutoDiagnostics Hi Ivan awesome skills. How did you get started in this line of work? Jim
Awesome diagnosis Ivan. A case study like this is what makes diagnostics so great.
if you're ever stumped like this again, ask yourself "what would scotty kilmer do". he's a diagnostic guru and such an expert with lab scopes and electronics as a whole.
It's insane how many oddball and/or mind-boggling problems can stem from the simplest of faults.
I salute you good sir!
Beautiful. Most technicians would have probably tapped out two videos ago and whipped out the parts cannon. I honestly wouldn't blame them. This shows the value of having the right tools and enough persistence to keep trying different things. You're the kind of person customers would want to have solving tricky problems.
As an aspiring tech, your videos are very useful as they open avenues of diagnoses I would have never otherwise considered. Great work!
Thank you! I definitely learned a lot on this one myself...just more tricks in the arsenal.
I'd be willing to bet the person who changed that relay with the generic one was the person that was in that fuse block. Great work!
One of your best!! I agree with all the other commenters that "a lesser diagnostician" would have given up OR put in many unneeded parts, or both.

That's exactly what I was thinking too! And it was in just right to make the problem very intermittent. You can't make this stuff up lol
Excellent case study. Being persistent usually pays off. A one in a million find.

Yeah, and this was just a simple single-relay circuit lol
I'd have yanked all my hair out on this one, lol!
NICE WORK!
I was wondering how you charged the customer too? I guess it would be a lot cheaper than a replacement car!
Electricity can do some strange things!
My theory is, since the pins in the plug were just lightly touching, just the temperature difference between a cold engine and a hot engine would cause enough expansion to complete the connection when warm, and separate it by contraction when cold.
Must have been the most satisfying thing ever. Congrats on sticking with that, man!

Mind blown Ivan! All that for a loose connector! Fantastic work as always.
Haha. Good find! The relief and excitement in your tone really tells the story of how exhausting this diag was.
Good job !!, it's a great feeling to finally get to the cause of the problem.This case study brought back memories, thanks for doing these videos Ivan.
Were they good memories?
Eh, for the most part.

Great work Ivan, all hope was almost gone there half way but persistence paid off.
Great study Ivan. You are persistent, the majority would have walked away.
Awesome detective work Ivan. You and the Pico kicked butt. Keep up the good works.
Nice, nice work Ivan ..you rocked this bad boy out man..thank you for this diag lesson.. This one most definitely had me scratching my head at first..God bless you brother
That blew my mind. I had to watch part 2 again to keep it straight.

Glad you got it figured out Ivan. Happy your enjoying your new Pico.
I was also glad that this saga came to a happy ending and didn't stretch out for weeks lol
Great job Ivan! Nice to see the Acer working flawlessly with the Pico.

Very impressed with your diag skills. Wish I had your talent and patience. Great work Ivan!
Having worked on pinballs for many years with intermittent faults we always checked fuses then connectors .the only thing you dint do is pull the connector right off inspected and plugged it back on , just the re-mating of the terminals sometimes helps .

I have to do the wiggle test to see if it solves the WARM start and stall on one of my beater cars. Nice find!
That was a very interesting case study! That must of been very satisfying to find the fix for this car.
Great job, took some time to troubleshoot but you gave it 100%
Very nice Ivan!! i've never been across such a problem on this model, and i do work on those subarus... Pico should pay for this... ;)
Good find for sure. Knew you would find it and thats a awesome scope
YAY! You found where the beans leaked out!
Good job Ivan! That was a hard intermittent fault, almost give up!!
Nice diagnosis & find Ivan. Good catch with the faulty backprobe, you could have been chasing a ghost! If it didn't set it on startup it had to be setting it hitting bumps also. After it didn't fail on load testing it pointed towards a contact issue or load detection circuit in the PCM & the ole harness shake test worked.

My 08 Liberty (legacy) is in the shop for this exact reason. I am going in tomorrow to check this out. I have also had this intermittent issue.
Fantastic work , almost got you , but you did not give up ! That's what I'm talking about...nice work dude..and you did it without your slippers on..lol
If I was wearing slippers with socks this would have been a 10 minute diag no sweat LOL
Hahahaaha lol, thanks for the very informative video..and sense of humor. ..
Awesome, you found the problem at last. I really like that you are persistent and don't give up easily. And let us learn from you. I have a cheap 2 channel Pico, and love it so far. But I'm no pro. Greetings from Norway :-)
Awesome fix Ivan, cool an unplugged connector.
Great case study Ivan.
Good repair. All it takes is a simple wire not making good contact.
A better and much cheaper tool for diagnosing intermittent is any old car speaker in series with a tail-light bulb. You hang the speaker and light across the circuit you want to monitor and then you can go wiggle things and you just listen for clicks and scrunches. With an occasional glance at the taillight to see if the juice is flowing. No scope, no eyeballs tied up, dirt cheap and very effective.
Cool tip!
Just to be clear--- speaker and light in SERIES! Otherwise you fry the speaker.
Про таких как ты говорят- гуру. продолжай в том же духе. удачи
nice job ivan,you nearly gave up ,but you solved it,thumbs up
never give up my friend good job
Ivan you are like me, loving technology. I knew you were going to fix it. 😉
Good job ivan that would drive anybody to drink.
ah the old wiggle test. Is there anything it can't fix? Great persistence there Ivan, nice work
If in a hury I would first do wiggle test. But this way deffinitelly better for experience and keep in shape. But somethimes in a busy shop you want to move to another vehicle as quick as posible.
Greetings from Serbia.
The lunch bell must have rung as the Union Plant Worker was installing the fuse box.
Do Subaru plants have union workers? If this was a Ford or GM than no doubt haha
Makes you wanna beat some little Japanese dude with a hammer. Awesome find. Hope that paid well for all the loss of sleep. That would have kept me awake for days.
Subaru not assembled in USA?
Cool , I had a gm power steering issue the other day , it was the power wire not fully clipped in to fuse box .
I was so close, darn. Didn't think about the connector connecting it. Not a winner, no chicken dinner.
Great diagnosis!
Way to be persistent! It paid off. Cool video and diagnosis. Love the pico (which one is it?). I'm curious what advantages the Verus has over it other than being more portable.
Man these 3 vids were awesome, glad you got to the bottom of it
Persistence pays off...... Nice scope..
Well done! In vid 2, you pulled the relay at about 9 mins, and same code 2102 set.

Excellent work. You were not lost, you were just in the forest, but you kept walking until you found the problem. Good job keep going. Since you are much more up to date than I am, what brand and model of laptop do you have to match the Pico scope.
Seems like visual inspections and wiggle/tap tests should be a high ranking action when troubleshooting weird intermittent problems
Fantastic find there Ivan, you have a very patient, persistent nature. Not too many would have found that.
Can I ask how many hours that owed you, and how many you charged?
Great job Ivan!
Sick! New subscriber here Bing watching lol. Great work and thinking.
Great fix and solid persistance in tracking it down.
Keep up the good work and remember your tripod please.
I finally got a small travel tripod! Don't know why it took so long...now I just have to remember to use it :)
fantastic diagnosis :)
Wow, great work!
One question, what is the program on your laptop used to view the wire was showing a open circuit.
I have the same problem. I changed the wires from the throttle to the pcm. #17 and 14 which go directly to the pcm. I just now checked that 30 amp fuse. It looked ok. Hopefully that’s the issue. I’ll push it in again and see what happens. Thanks.
The reason why the owner could not get it to come out of limp home was he was not waiting for that relay to time out !
Great that you found the fault but what is really amazing was that the fault was reproducible. Had the fault been intermittent then this might have provided a bit more of clue about intermittent electrical continuity. I like the scope but a detailed .visual inspection and wiggle test first can sometimes be a time saver.
Hindsight is always 20/20...the wiggle test can get you in trouble when you accidentally fix the problem itself, which I was trying to avoid. It's definitely a fine line, but yes, I should have gone for the wiggle test a bit sooner in the process :)
I say hindsight is 20/15! Can always say, SHOULD HAVE----WOULD HAVE----COULD HAVE!
+motoYam82 I'm old school (carbs, push rods, distributor shaft, vacuum advance timing) and so my approach is very much still push, pull and examine :-)
i have that same small yellow prybar from harbor freight hahah. great fix
omg I use that little guy every day! Super handy for sure?
How does the problem showing up on a cold first start of the morning fit in here? Would how and where the car was sitting play any part in that? Parking on a incline driveway causing the connecting to pull apart?
Wow, you are Persistent.
That's great my brother thanks 🙏 so much
nice find, i know technicians that would've driven the owner to bankruptcy with a problem like this
Way to stick with it Ivan!
Awesome job!
My brains in limp mode right now. After watching this. I have those same codes on my toyota corolla 2005. And now after watching this i dont know what to look for .
LOL! Watch the video again and take some notes. Wiring diagrams are key. Be brave!
I feel you, bro
Great work, man. You know, you really could have used the load pro leads to tie your camera to the hood prop, since you forgot your tripod. Just a thought...
Awesome series and fix! Probably a stupid question, but how is the throttle being controlled during the periods when the relay is not functioning?
Great question! PCM still controls throttle but it only opens like 10% so it doesn't need a high-power feed to do that.
