L322 suspeion inactive

hi guys i've had a problem with the car since i bought it 3 years ago and so far no one has found it, whenever i drive the car in the wet i get suspension inactive pop up in the dash, this also triggers an abs fault (no message from ride height) all the connectors on on height sensors, suspension ecu and abs pump have all been cleaned and checked. so i'm lost where to look now. however i do get transfer case errors occasionally too so is it possible a faulty/dirty connector on the transfer case could be pulling the bus down?

It's an L322 therefore unreliable electric unless maintained. Sounds like you have dodgy wet connectors underneath.

That was my thought, however it seems previous owner replaced all the height sensors with genuine LR so it's time to clean all the connectors. Failing that it could be a faulty suspension Ecu.
