Ok, so we all know HICAS shits itself easily if the steering wheel is non-standard with a non-HICAS boss, and when our steering wheels are not centred.
My car came from Japan with a Nardi wheel with an appropriate boss. I had no HICAS light illumination at all. I went to the trouble of removing the wheel and fitted a stock GTR wheel to my car (R32 GTR). Since then, after 10km of driving, the HICAS light illuminates. I put it down to the wheel being off centre, but I can't for the life of me see how I can get it any more centred than it is!
The other problem I have relates to the cancellation of turn signals. When my wheel points slightly to the right, I find it very hard to keep the indicator on - the cancellation block is obviously close to the switch, which is terribly annoying.
Today I decided to pull the wheel off and have a play around with the HICAS sensor located under the steering wheel, to see if it was perhaps off-centre.
A bit more background... with the Nardi wheel, the HICAS lugs sticking out of the steering angle sensor were sitting at the 12 o'clock and 6 o'clock positions; the factory wheel requires them to be in the 2 o'clock and 7 o'clock positions. Is this normal?
I took the sensor off to have a look at that, to see if it was perhaps 180 degrees out, but it appears not. I also took the back off the steering wheel to see what's inside... I thought that the lug slots were possibly sitting 180 degrees from where they should.
I've attached some pics to show all the details for those who can help, and for those who would like to see how a HICAS steering wheel works.
I'm dumbfounded as to the cause of my problem. Can anyone shed any light on the matter?
