4WS problem 1995 Gen 4 Prelude Si - HELP!!!

How's it going all?

I've got a small (I hope) problem with my 1995 Prelude Si.

A few weeks ago, I noticed the 4WS light was comming on, and
staying on, so I took it to my Honda service centre, and they said it was a problem which may need to be traced through the car's computer system and could be quite costly. They said it can be caused due to say hitting a curb, or knocking the wheel.
Anyways, the light turned off by itself a few minutes after I left the Honda service centre, saving me from any repairs.
The problem has since re-occured, comming on last Saturday, and still hasnt' resolved itself.

Has anyone else had this problem, and if so, what was found to be the cause, and what was done about it?

Thanks peeps!
