Need help with Pibus and RPi3B+

[TooEasyL2P]

is it working now?

No Have updated to newest version.
And I don't know what might be wrong.
Every other function that I tried is working.
Mirrors are working with button as well.

Could you add a button that folds or unfolds mirrors? Maybe the problem that it's not activating it when car is locking up? By pressing that button at least it would be clear if signal from board doesn't come or is lost somewhere in between.
