parking sensors have stopped working

[pollardive]

I have just fitted a dedicated towbar wiring kit from westfalia, disocnnected the battery while I connected the wires, battery connected again but no parking sensors. any ideas appreciated.pushing the parking sensor button seems to do nothing. is there a way to reset them?

Doesn't it need coding?
