I found out the problem. During several ECU connecting and disconnecting procedures I've managed to smash one of the pins quite badly, so 12v pin was in conastant contact with ground pin.
Lucily nothing got permanently broken, I straightened the pin, deleted ecu error codes and the car started nicely.
So the ecu unbrick process was a success!

I used a standard USB-TTL interface and it worked great with Renesas Development Toolkit Basic

But for a long time I had 2 major things wrong:

1) The DIY timer was a mess, so I bought a simple NE555 generator for 4 dollars and used multimeter to finetune frequency to 135mz and duty cycle to 50%

2) At first I didn't notice to connect USB ground, P413 and ECU ground all together.

Thank you for all the help!
