Hicas Light problem

Hey,
Anyway from time and time my Hicas light will come on and stay on even if I’m just driving straight. Anybody have this happen to them before? and how can I remedy this?

85% of the time, HICAS problems are related to your power steering fluid level.

10% of the time, your steering wheel isnt aligned properly/other alignment issues. (On the GTR, HICAS uses a steering angle sensor attached to the wheel hub, the 240SX should be the same)

5% of the time, there is actually something WRONG with the HICAS.

yup
