The idle was a little rough and hard to get correctly adjusted and there was a hesitation during sudden acceleration. So far it seems it might be a little better now, pending further adjustments to the mechanicals to compensate.
Make sure to use the same capacitance, equal or greater voltage, and always use at least 105 degree C temperature rated caps from a reputable brand. Also, only buy from reputable sellers, Digikey, Mouser, Arrow, Element14, RS Components etc. Forget abouy buying from ebay, Amazon, etc. Too many fakes and crap.
I think I am having the same issue but with my Throttle Control Unit! I have a 97 Chaser Tourer V. TRC OFF and ETCS SNOW constantly flashing. Power delivery is laggy and idle is rough. Is there a possible way you can assist I am in Okinawa, Jp.
I'll have to check with the owner how the idle is like on this car, bad idle is a known thing with these cars and is an ongoing battle the owner is having with this car too. My suggestion to him is to rebuild the engine and use after-market engine management, but that's easier to say than afford when it's not your car... :D
@jorge, I also own a 97 chaser tourer v. The trc and etsc flashing lights mean your traction control ECU is bad. Common problem on the jzx100. Power delivery / rough idle is almost guaranteed your maf sensor starting to shit the bed. If not that, then it’s definitely your vvti solenoid
Hi @NFM i have a 2JZGTE ecu that i think has leaking capacitors... i am looking for someone in aus who knows these ecus and can do the work.... is this a service you provide? the car won't fire up now... and when i checked the ecu there was some fluid leak near the first plug/pin set. Don't know what to do and don't want to trust this to just anyone who doesn't know supras/ecus etc.
Unfortunately I'm in Japan so it's a little difficult... I'm not sure who else to get to do it either as I always just did it myself. Sorry I can't be of more help!
I wish mine was that easy, The 2008 Nissan ECU is mounted in a much harder place to get in and out. My module shorted out and blew the 5 volt reg on the input, (it has more than one). So I have to trace it down to where the short is. I hope it is a cap but my luck it will be the CPU. Still a Toyota part though, Nissan used Toyota parts in the Hybrid.
@@NearFarMedia Thanks, I can't get any help on this one, I'm going to the dealer to teach their service person, he is just like me and a nice guy. My point was the Nissan hybrid and the Toyota are identical.
No conformal coating? Automotive boards are often covered with some how-the-hell-do-you-remove-it awesomeness, often turning a simple repair job into a meditative journey.
Toyota are nice in this regard that they use a solder-through conformal coating. None of that thick impervious layer of blast armour some manufacturers use. :D
We didn't bother as we were mainly interested in making sure they were all perfect before chasing any potential problems elsewhere. The capacitors used by Toyota in the '90's were very prone to failure (I've repaired tens of ECU's in the past) so even though these were a bit newer we weren't going to take chances so we replaced them regardless of how they tested. They were old enough (almost 20 years) that new caps definitely wasn't going to be a bad thing.
It's not clear to me, why you change these caps, but endanger the expensive ECU by not wearing any ESD protection. Valeo is one of very renowned Automotive suppliers, beneath Bosch, Continental and others, and all of them validate the components for a full car lifetime, and these have also to fulfill AEC-Q200. They also use AND qualify good brands like Nichicon, therefore an elco fraud as for motherboards is near to impossible. Why you do not check the old caps, is obvious, because that action was not necessary at all.
My workbench is completely covered in an ESD mat so the workstation is safe. :) I've repaired a multitude of Toyota ECU's in the past with bad, dry and leaky capacitors. It's particularly common in the 90's models. Nichicon was at the center of the bad capacitors problem when their formulas were stolen and counterfeited, and Toyota wasn't immune to having faulty capacitors in their products. The capacitor replacement was done to give us a clean baseline for future modifications and troubleshooting on the engine, the capacitors installed were almost 20 years old and certain problems were appearing that are common in Toyota ECU's when the capacitors start showing their age, like unstable idle and stuttering/hesitation when accelerating from standstill. We decided to spend a few dollars now rather than potentially chase our tails later on.
@@NearFarMedia The brand Nichicon itself was NOT affected, escpecially NOT automotive grade types, afaik! It was only their recipe counterfeited in no-name brands, which VALEO (or others) for sure would never have qualified/purchased! Also, you need to wear an ESD strap, otherwise your nice ESD safe environment is useless. I'm working in the development of a huge Automotive electronics supplier for a long time, so I look very differently on your handling as you probably do yourself. If you ruin this PCB by ESD damage, your car will be a complete write-off. As it's 20 years old, as you have written down in the comments, there will be probably no spare parts any more, as the usual OES obligation in this industry is 10 to 15 years after EOP. Most parts on this PCB are unobtainium, either due to PTNs, or because they are automotive - custom specific ones, and especially the µC are probably mask programmed. Therefore you should have shown in your video, that you need to take extraordinary care when tinkering on these electronic devices.
@@johis69 Hello, these videos are a guide for others, maybe less experienced viewers. If the NFM author of this video bricks his car by ESD damage, then it's really enough for his own purpose, but a disservice for others (we are talking about some investment in this case). I'm disappointed, that this basically really good channel demonstrates the recapping in such a non professional way. Another aspect is, that 20 years ago, the ESD protection of the semiconductors, and also of the whole PCB was much worse than today, so with these old devices you have to be extra careful. After 20 years, OES spares are probably not available, only 2nd hand stuff of probably dubious origin or state. Valeo may not have the best reputation of the Tier 1 suppliers, but this PCB looks like all of them looked 20 years ago, as far as I can compare. Toyota themselves very probably had taken care, that this device is working reliably over a long time, by making some extra pressure on the validation, as they do until up to date.. so how or why do you judge over this PCB so badly?
@@DrFrank-xj9bc I agree genuine Nichicon capacitors weren't the problem, it was the counterfeits that made their way into the supply chains that were. I could wear an ESD strap but I am in constant contact with the ESD mat anyway so I'm well grounded enough.

Was the broke down before repair?

@@NearFarMedia Great job, better fix now than later
@@NearFarMedia CPU relearning, don't adjust until run for a while. Often mentioned in repair manual, for example throttle idle reset.
No ESD strap?
I have an ESD mat covering the entire table. :)
Hello, can you help me to buy a set of capacitors for my jzx110 1jzgte Verossa in Japan? How can I get in contact with you?
Very nicely detailed and well researched video. 👏🏻👍
What cap would you suggest for a bone stock 1uzfe gen 2 ECU that’s mounted behind glovebox ??

What are you using for a desoldering station? I'm currently looking for one.
I'm using a Hakko FM-206 with FM-2027 soldering iron, FM-2024 desoldering tool and an FM-2029 hot air tool.

Where can i get the correct capacitors for 90s Toyota ECUs? Nice video 😎
I buy my capacitors from Mouser and Digikey. Good luck on your repairs! :)
@@NearFarMedia where in japan are you located?
