When the ignition is turned to position 2 the HDC warning light comes on and chimes non stop. When the car is started it goes away but there is a psss sound coming from the right wheel or above it in the engine area. Psss. It will stop for 10-20 seonds then psss again. 10-20 seconds psss again. Non stop. It feels like The Rova is driving a little sluggish but am not sure.

This happened after I power washed the under carriage. Does anyone know what it could be? No codes.

 

It's the green HDC light upper left corner ..
