Nice one sir. Being learning a lot of stuffs over here. I see alot of Toyota hybrid ECUs, especially, Prius models. They often have green stuffs in them. I think the summary of this video is that, the older ECUs, are prone to capacitor leak failures, and corrosion on the PCBs.

thanks for the video now here is my story i drive a 2007 Toyota Mark x its has the 4GR engine this Engine is similar OR almost Similar to the engine in Lexus is250, many years ago i developed a minor problem with transmission Which seemed to clear away by itself the car Would REV so high(4000RPM) and the rev will not match the speed it was engaging gears 1, 2, 3 but omitting 4 ,5,6 reported to mechanic .. all he did was disconnect the negative side of the battery terminal and reconnect it back then the car performed well with no problem Many months later this problem came once in a while and i did resolve it by disconnecting the battery terminal the problem became more and or routine service i asked the dealer to service my gear box by changing the ATF which was done and problem still persisted, one day on routine battery service the technical told me my battery voltage is low(9.0)V There was no Check engine light , no Battery flashing all good) He Said "U NEED TO REPLACE YOUR ALTERNATOR SOON"look like the alternator is not charging well, he allowed me to drive Few weeks later the Starter died and we had to replace it after replacing the STARTER 2 months passed by and the second STARTER ALSO died we replaced it with a new STARTER thereby after 3 months the ALTERNATOR "DIED/FAILED" question 1 WAS THE POOR OR LOW VOLTAGE FROM THE ALTERNATOR CAUSING THE STARTERS TO DIE? 2. WAS THE LOW VOLTAGE ALSO CAUSING THE COMPUTER TO MALFUNCTION we replaced THE ALTERNATOR and on that replacement we got a volt reading of 12.4V now back to the Transmission the problem became more common NOW I HAD to always reset the ECU by disconnecting the negative side of the battery every time i want to drive and when i switch off the car if i have to drive it i have to reset by the same procedure and this became annoying on diagnostic no error code was captured THEN gear box dealer decided we replace the shift solenoid which we did all 8 of them same problem car shift 123 not 456 Very annoying he then decided its an electrical problem then we took to electrician he Scanned said error codep0176( shift body solenoid c remain open) learning p603 engine stall history He said he cannot fix my car because which 2 " am not sure if its the gear box or ECU OR WIRING" GAVE ME MORE HEADACHE 3.Imay be forced to strip off the car and that is too much of a job to do definitely Replaced TIL I SAW THIS VIDEO QUESTION 1 from my history do u think this is an ECU PROBLEM 2.I CANT FIND A TRANSMISSION WIRING DIAGRAM ANYWHERE ON THS CAR WILL CHANGING THE ECU NEW ECU BE A HELP remember the disconnecting and connecting battery terminal to reset then the car wud function well Please help my e mail mikdan2006@yahoo.com mik2013@gmail.com

Proper Diagnoses is very important. Low battery voltage can cause many issues with items like starters, alternators and ecus so its vital that these components are in good order. We are also seeing lots of ECU issues on the later vehices causing poor shifts like you are experiencing. I would recommend proper testing to identify the issue but in this case I wouldnt be surprized that the ecu may be the cause, based upon the info you provided. Cheers

Bout to send it out to get repaired. Before this happen I was wondering why I was getting crap fuel economy and such.

Hey kelvin, been watching your vids for a while and they’re very informative and well put together. Nice work Do you know if common electrical repair/computer shops with techs that have a knack for working on circuit boards soldering and the like would be skilled enough to do a re-cap and general inspection/service of these old ECU’s? Can I trust them with a UCF10 ecu? I’m in OZ and not sure where else to try, I’d do it myself but I’m a pretty heavy handed heavy diesel mech with minimal solder skills

Note to everyone here, it only took a few minutes to pull and open up the ECU, do it now if you haven't yet! I vaguely remember watching this two years ago, paid no heed to the concerns ahead and now I'm back lol. The one capacitor on the sister board has splooged all its guts but the rest are intact so I'm gonna try this repair myself as it would cost more than what I spent on the sc400 entirely

Hey Kelvin. Very informative viedeo as always 😊👍 I actually got some issues with my 1uz ls400 that can be the ecu. I have also talked with Josh. I got a crank no start issue. coils seems good. ignitors seems good. The thing is im not getting any 12v igniton power to either the coils or the ignitors. Im not getting any voltage from the ecu either. The car ran fine a week ago. But one day over night it just stopped starting. Could this be a relay issue since i do not got ignirion 12v to the coils. and witch relay is it? 😊

@CartuneNZ
3 жыл бұрын
Differences vary between years so due to this the answer is generic. Most ls400 have egr and a viscous fan. Most celsior have no egr and a hydraulic fan. Some models of celsior have air bag suspension. Therefore Im fine using celsior ecu into ls400 but going the ls400 ecu into celsior can cause many issues so I avoid it.
