Low coolant warning when parked coolant full

[stevesparts]

It might be a harness problem,that's what i had on my w900 it would trip when it got moved or wet the it would go away after i got going down to road. my harness was under 150.00. and it was not hard to change out. but check for lose connection first just in case :)
that's my 2 cent answer. good luck.
