I recently replaced my standard steering wheel with to a Momo sport steering wheel, in my 1994 R33 Skyline.Now a few people have said am i sure its a 33 and yes is a mspec r33 1994

Now every now and again i get the Hicas light light up. What is it and should i be worried about it? other told me its my power steering fluid is low but i checked that and its fine, so what could it be??

mine lights up it seems when my hicas was working. also, yes there were some r33's made in 1994. the only one i know of however came with an rb25e, but there may be more

I can be a number of factors, but with the early R33's changing the steering wheel did often cause the HICAST light to illuminate. You know you have a serious problem when you fell a pulsating in the steering wheel while turning. This means there is a mechanical problem within the HICAS system.
Another cause for the lamp to light up is low battery voltage i.e. a bad alternator or battery, or simply too much current drain from a stereo etc.

It could also be something as simple as an air bubble too. My light only comes on when im on the highway i have been told it would most likely b an air pocket in the hydrolics or something.

By changing the stering wheel on your 33 you need to buy the hub adaptor the sensor is reading everything wrong now....momo makes one for the skyline it just a little black round cylinder that sits behind your steering wheel. or is this problem fixed already being it been in here for so long>/
