What was the last thing you did to the car before the light started coming on?

It means it is getting an error of some sort and going into its failsafe mode. You need to work out what is causing the error.

I once had it happen when I shorted the speed signal wire, kept happening. Simply reset the factory ECU (disconnected the battery over night) and hey presto was fine again.

Have you taken your steering wheel off lately? if it's not quite on straight, after a few minutes of driving HICAS will think you're driving in a really big circle and throw up an error..

Does your speedo still work?

the way it knows is there's a hicas related clock spring type wheel behind the steering wheel that turns with your steering wheel. so it keeps track of the angle. 'steering angle sensor'

but i dont know why ppl keep saying check if your steering wheel is off by a tiny bit. coz the splines dont allow you to be off by a tiny bit. it's very noticeable if you're off if only by one tooth.

i suggest taking your boss kit off and check that it has the appropriate holes in the back for the steering angle sensor to lock into. also, check that the sensor is still there.

There is a steering angle sensor behind the boss, HICAS uses steering angle and speed input to decide what it's doing. Even one tooth out will freak the system out.. I'm talking teeth of the splined shaft that the boss goes on to, not the 6 bolts that hold the steering wheel to the boss.

The sensor is a big white looking disc thing with two posts standing proud of it... really hard to miss.. as soon as you take the boss off there it is.

But +1 for binning HICAS. You don't have as much of a weight saving in the R33's but I hate HICAS and removing it gave me more confidence in the abilities of the car as opposed to not being entirely sure what the back end was going to do..

Fortunately, my Stagea came from the factory without it :)

ok an how is the disc supposed to sit? or am i just making sure its in there?

also, while where on the topic, how hard is it to bin the hicus? is it as simple as unbolting and unpluggin the wires and putting in the bar? or will i need to screw around with the wireing etc, and will i need a wheel alignment? how hard is it? whats involved?

Mine did this. Would always come on just outside of Sydney on the way back to Canberra, but never any other time....inclusive of the way TO Sydney :S

I personally just pissed it off with a lock bar when I got my suspension etc done, but that's obviously not fixing the problem (unless of course you agree that HICAS itself is the problem in the first place)

His is an R33.. I know the 32 will light up the HICAS light if the fluid level is low but doubt the R33 does the same..

yeh i thought it still did as it simply doubled as a hicas/steering fluid warning. im probably wrong, i dont like to meddle in r33 things usually lol

do r33's have a separate warning light for the steering fluid sensor?

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
