now i took the encoder out of the bus (so i have the relay directly hooked up) and try to check several times in a loop (just to give it a chance) and from what i can see the first time i get an arbitration loss and after that it doesn't return:
```
0.510272 [INFO ] checking connection...
0.510999 [INFO ] result: Err(Abort(ArbitrationLoss))
1.011607 [INFO ] checking connection...
```

if i leave the check out i can talk to the relay without problem and toggle it
