Hey all,
I have a 94' R33 GTS-t and today the yellow HICAS light came on. After this the steering felt a lot heavier and not very nice at all. In the days leading up to this, I'm pretty sure I noticed a bit of a whining noise coming from the rear cradle (this is where the HICAS pump is, yes?) this was after the car was turned off and lasted about 25 seconds.
Do the HICAS pumps contain oil? Is it possible it's just low on fluid if they do, or could it be completely rooted?
Comments appreciated, I don't know much about HICAS
