I replaced all the capacitors, the problem remained.

Which S300 pin getting power? How i can check this?

Please see this image(with lamps); How should the lamps light up?

I recorded video with my problem. When you listen beep-beep it's i turn on ignition..

I replaced C21 and C24 capacitors, but nothing changed.

When i connect PC to S300 (without ignition) SManager show online status.
When i turn on ignition, nothing not change.

Do you have any other ideas?

Also check to make sure that there is nothing leaking from any of the capacitors on the ECU. There is a very high possibility that the capacitors are going bad and need to be replaced.

We offer a replacement kit for this: https://www.hondata.com/products/accessories/capacitor-kit

Leaked ...

Can i check work state on the S300 (green light, red light etc..) ?
