Now it looks like, that all coil wires are OK. There is 12V with ignition, ground is OK and now I can tell that signal wire is also OK.

Unfortunatelly this leads me to ECU...

I think you are right.
Ebay is a good source for inexpensive ECUs. I have purchased them for as low $50 US (plus shipping, duty and taxes of $50 to Canada, so $100 total)

I believe you will need to have the VIN re-programmed, and re-sync the ECU and BCM so your intelligent keys will work and you can start the car.

-OR-
you can unsolder the EEPROM (95320 4Kb) and move it to the replacement ECU.

-OR-
you can read the old EEPROM and write to the replacement ECU EEPROM.

Good luck!
