Hi mates. I'm new at this world, if experts can help I will appreciate it !! I have bought recently a model S salvage tesla 2015/06. I replaced the onboard charger and driver seat module that was not working. Now I'm trying to find MCU problem. It doesn't turn on, I test it on bench, it starts fans and stop immediately. But the lights still on. There are 4 check LEDs that don't turn on (uploaded image) Does someone knows the problem? Do I need a new MCU? I also will need someone who can program all the replaced parts. And ofcourse I will pay for it. Thanks mates !
