I've read a couple of things about why HICAS lights come on (power steering fluid low, alternator gone, HICAS dead), but my situation seems a little different.
It comes on when I cold start the car, and once I've been driving around for about 15 mins it switches off. Then it'll come back on only if things get a bit tail happy or traction is lost. Otherwise, it seems to stay off.
Is this normal?
