This is relay with remote control by RFID (no need to press button with the remote control). The relay has small accumulator battery inside. When first time relay activated (DC voltage to the control legs), then it checks remote control by RFID and if present, then start working as regular relay. The battery inside relay required for safety (so it doesn't disable during driving when RFID fails for any reason). The relay turns off when car off and no remote control inside the car.

It is possible to charge remote control like a cell phone. BTW, click on the photo itself if you want to see what was written (...) for the photo above, and just use arrows left/right in new view photos mode then.

Changed "IG2 No.1" (that is "Multiport Fuel Injection System/Sequential Multiport Fuel Injection System") to the new relay with secret. Now would not be possible to start engine without remote control present. If remote control present, then everything works naturally. If you try to start the car without remote control, then you can start hybrid system without errors, but cannot start engine at all (can see errors like "PCS fail" on dashboard when trying to start engine). What is good, even after fail with errors, then next time you can start car without errors if remote control present.

The names of relays for the photo above. Checked first with relay for "horn" (so to actually hear when horn works and when not if without remote control), then checked that doesn't work good with the "EFI No.1" and found that works as expected with the "IG2 No.1".
