This is absolutely awesome to see the teamwork building and building. I'm excited and just started watching. I'm really gutted that I didn't plan ahead and take off work a few more days. Keep up the awesome work Ivan and Maic 👍🏻
Damn, you got to work with Maic! You and Maic make a great pair especially when it comes to component level repairs. You've officially arrived Ivan. Well done and congrats!
Electrical problems are always interesting, especially when the problem is there and then it's not. It's been awhile since I've watched your videos so I'm on a Pine Hollow Auto Diagnostics video binge right now, lol.
Funny thing about capacitors Ivan. They can wear out from several cycles of use and usually it is because they are being slightly over worked (over amped). Lastly they can point you in the direction of the cause of why they blew.
Great video Ivan! A strange one the way it was acting up. Communicating, then not, then runs and not. Good to see Maic lending a hand too. Great to see the bond of technicians helping and hanging out together!
Remove the cap, clean the juice off the board (it may be conductive which is worse) & repair the traces if they are eaten through. A replacement used ECM might run about $150-300 so worth a try with this older car. Fun to see your approach to this problem - I would probably have latched onto the working, then not working com aspect, which would have still ended up in the ecm. Thanks for the video!
Nice team work, those kinds of electrical problems can be a nightmare. But i think the fact that the ecu works for a few seconds points to the electrical tracks being ok and its just that capacitor bringing the circuit down, i will guess the internal resistance of that cap is through the roof. I would certainly replace the cap, for what they cost - pennies, it's well worth it.
Excellent video, consider the quality of the Lexus, going on 24 years old and it's drought to a stop by a capacitor destroying the engine management computer, clearly everyone got there money's worth out of this car
I'm waiting to see if any vehicle made today will be around in 24 years ;) we all know the answer to that, NOPE.... unless someone still sells and repairs all the computers, wire harness and sensors, I'm willing to bet that would also be a NOPE.
Teamwork! Nice job, fellas! 👍🍻 Wish I could've made it down there for SS. Was on my wife's birthday this year. After this year's trip to OH, I doubt I could've made it even if it wasn't. The funds just aren't there. Long ride from here, and I guess you can't camp there in the city. 🤣 Hopefully I can make it some day, even if it's just to hang in the parking lot with you guys afterwards, lol.
electrolytic is probably a filter capacitor between the power rail and ground rail. just cut it out for proof of concept. it may be a little jittery but it should run. there is going to be a time when good cars go to scrap because the electronics are no longer available
I agree 100%. Should have just cut it out and cleaned it up on both sides of the board. It probably would have come back to life. As you say good enough to prove it is the problem.
Those type caps are usually for filtering noise. Since it would start and run for a minute after removing power it probably would not work without it either. The noise is causing the computer to have a brain freeze.
Yes they are for noise reduction / elimination but usually there are several scattered around the circuit board all in parallel across the supply with not too much thought or serious design. (More is better). If the cap is shorted (like it probably was) or the contents of it's guts was (likely) causing a problem then removing it just for the purposes of seeing if the PCM operates differently is a good approach. If removing it is an obvious fix then a new one should be installed to fix it for the long run. BTW all the other similar caps should be changed as well. They are probably not far behind in failing.
@@davesage9190 Most of what you said is true but not always. Obviously the cap was a filter for the communication part of the circuit. I have seen where one filter cap can affect only part of a total circuit design. I have even seen where replacing a 220uf with a 1000uf caused major problems. Main thing there is a lot of assumption about the cause/effect which we are all doing at this point. Without a schematic or circuit analysis/troubleshooting we don't really know do we?
A lot of times it's the small caps in switching power supplies that cause them to stop working. The part of the circuit they were in hammered them with high frequencies causing the electrolyte to dry up causing high ESR.
Clean the traces, scrub it with a fibreglass pen and see if they are broken, jump them and a new capacitor. Max 1 hour work. Did it years ago on my MK4 airbag pcm and it worked until I dumped the car.
Pretty rare to see a Toyota ECM go bad. In 25 yrs I've only done 3 that I can recall. Wonder what smoked the cap? I'd be leery of putting a used 1 in it with the reflash, without digging a bit to find out why it happened. Nice teamwork. I will look up his channel.
likely just age, although it looked to be one of the better brands. so maybe a bad sensor or wires melted and 12v+ going in a 5v or sensor line. I wonder what the cap rating was =p
Привет, Иван! Конечной целью была диагностика или полный ремонт? Почему бы не отмыть электролит с платы, заменить конденсатор и проверить работу... Смотрю с интересом! Денис
I would rebuild this PCM. Traces are no problem. Its 2 layer PCB probably be couse that it old device. Its worth to change all electrolythic capacitors there.
There is very little that can take down a Toyota...Leave it to an electrolytic capacitor. If this was your own car you could get in there with some jumper wires. I've seen old motor coil winding used since they have that thin insulation coating on it. Scrape each side of the bad spot and solder them on. Then change out the other caps. A used PCM will have the same issue. Maybe buy a used one and hope it's not as bad, change the caps, and then install it.
Great video Ivan it was nice to meet you at super Saturday I think we were the last 4 to leave that night lol. Wanted to put my name to my channel... Jay
Nice work guys again the computers are always an issue in cars today this is one way the dealer can get more money out of the consumer i glad the old school way was so easy to work on and always be Thanks guys.....
How did you feel working with a Latino that tries to fix everything, I wonder how many mechanics would even attempt to open the PCM and try to fix it instead of just getting a new one
It was a great time hanging out with you 2 the night prior! I wish I could've done it all! I went the SI & NYC with Keith, Steve, & the other Brits, which was an amazing time as well! Just not enough hours in a day! It looked like it was just as fun as though..... diags in my own area! Lol😅😂. "Philly Diag Express"?.

Oh, come on, that's totally repairable. Clean up the board, test a couple traces, some jumper wires if any traces are broken, no big deal.

My '99 Camry with 410,000 miles has issues with the traction light staying on. On occasion, it's gone off. When that happens, I can control it with the button. I'm thinking it's a cap issue in the CPU. Thoughts? Great video!
@@wms201 My dad had a 3800 engine with 500,000 km and salt got the better of the car - we live in Canada. But, the engine was still going strong. 3800 series engine is the best engine in the history of the automotive world. GM sold over 25 million of those engines and they proved to be extremely reliable - even better than Toyota engines.
This Lexus has already outlasted most vehicles from the age and mileage. The 3800's are not the best engines in the world, that is an opinion you made yourself. Nobody has proved they are better than Toyota engines.
I realize that Lexus may be someone's only wheels, but as trashed as it is on the inside, and with 300k on the clock, it needs to be put out of it's misery...

That's crazy! I discovered Maic two weeks ago doing an evaporator core on a Camry,.. Now this! Sweet
Thinking that was about the same time motherboards on PCs had many bad electrolytic capacitors. Something to look for on older cars.
It’s so good to see you guys together. Awesome work cheers 👍👍😁
Those large traces are easily fixable to jump change caps. The electrolyte is conducting those traces together.
I think that was the car saying, enough - if you won’t clean me I’m stopping right here. Yuk, nice one as ever.
Good Diag, thanks to both of you!
Wow, great video collab! Nice and hard diag. But you guys called it! Great job!

Hey Ivan. At 300,000 miles/500,000 kms, the next stop is the junkyard.
Cut the capacitor out and use flux remover to clean the board. Tack a new cap onto the solder pads/pass throughs.
Clean the traces, scrub it with a fibreglass pen and see if they are broken, jump them and a new capacitor. Max 1 hour work. Did it years ago on my MK4 airbag pcm and it worked until I dumped the car.
