Glad to hear it!

Amazing. The most entertaining :)

The red is glue from when they wave solder the boards.. so the parts don't move. Not a leaking capacitor. This is red glue, which is originally designed for the purpose of sticking SMD parts to the circuit board,so the process is also called SMT red glue process. And then the circuit board can pass through wave soldering furnace, so that the parts can be stained with tin and bonded to the welding pad on the circuit board.

The problem was 100% from the electrolytic leaking out of capacitor directly above it and that seeped through the via's under the soic chip. There is the glue there you speak of as well but thats not what the liquid is.

I'm going to start working mainly on these boards myself. Along with Solar controllers & inverters.. commercial or residential services. 👋

what did you replace the controller chip for the mosfet that control the sparks

the meter works in cc mode measures the voltage drop and divides by that cc , try if you have the option to increase it to 1 ma it`s usually at 500uA and 2.8V some have the option and allows a more definite measure because 500ua is many times to small to measure semiconductor behaviour especially when the channels are wide like in the case of this igbts , i usually use the bench supply at 5ma configured in cc with the voltage capped at 1.2v

Hello Sir Amazing video Sir I am just 17 I am going to start this job so what you recommend I have no idea what I must Buy I watched video 1000 times about multimeter and ossilascope but I can not understand it yet,So you are as proseffional what are you recommend? with Best regards

I wish i knew why those caps leaks. Happens a lot in the hyundai hb20 module and some peugeot modules too, damages traces even. Good job and great video. Cheers!

is there any way to get schematics on these ECU's or pretty much you troubleshoot following the circuit

@ecurepair

No schematics. You have to trace it all out yourself.

Have seen just yesterday on youtube some guys doing repairs mentioned site where you can find schematic. Perhaps not all ECU but many and information is not free. Don't know is it subscription or one time payment .

It will be homemade stuff if its true at all, but to be honest you really dont need schematics. You just need external harness pinout which is easy enough to find freely off the web.

@snail2171 I like the saying, Thankfully its not too much like that for ecu work. Its fairly easy to trace the circuits based off the symptoms and pinout data.

Please don’t use hot glue on ECUs, I recommend using the black bostik here as well.

Truthfully I never use hot glue. Thats why I make such a mess of it. In this video I happened to have a stick beside me from where I was putting some transponder keys together and decided to experiment with it. I had already cloned a replacement unit the customer would be using. Hot glue is pretty safe to use for electronics though and the melting point should be high enough to not be a problem. I usually use a special oxime silicone that I have done numerous tests on to ensure it safe for use.

Looks like all the new stuff is being made to fail and stay failed much like battery BMS systems. Only those with the microprocessor firmwares that can program will be able to fix things. Microprocessors will lockout when sensing certain errors. Thats the way its gonna be my homies.
