Another Hicas Question From Newbie!

hey all.

my 2nd post here.

yes i have done a search..

however there are 40 threads with the title hicas.

haven't been through em all but most and can't really find what i'm after.

so i just purchased a r32.

i asked the guy about the hicas light and he told me it's on cos of the after marker steering wheel.

after searching a few threads it seems that this is true, if you fit an aftermarket steering wheel the hicas comes on.

the guy that sold me the car said that the light being on will not affect the car.

i know i can do the diagnostic test but just need to know if it's alright if i leave it as it is? if it's just the after market steering wheel causing the light to come on?

or do i need to get proper boss kit or lock the hicas?

your help is appreciated.

thanks!

Fairly certain that if the light is on, then the HICAS is disabled (because there is a problem with it).

so does that means it's ok for me to leave it like that?

it just simply means at speeds over 80k's, the 4 wheel steering won't kick in and make the car understeer more?

thanks

anyone able to give a firm answer on these questions?

if abs is disabled.. this is a major worry!

HICAS is seperate to ABS so dont worry there. it just isnt reading right from the steering so the light is on. Just get a lock bar and be done with it lol.

I must be thinking of ATTESSA sorry, ATTESSA and ABS share the same sensors and fuse, so when you pull it out it disables both. Or when ones not working, the other doesn't work.

the question is do i really need a lock bar?

any problems if i leave it just the way it is?

previous owner has had it like that for the whole time he has had the car.

if it's just the light on the dash and the all wheel steering that doesn't work then besides that it should be fine to leave it like that right???

surely someone can tell me this?

thanks!

It could be that the steering wheel isnt on straight, it's out by say 1 tooth, it's enough to trip the HICAS light. Can be corrected by putting the wheel back on with the wheels perfectly straight.

You can live with the HICAS light on, shouldn't see any problems, but for daily driving Nissan put it there as a safety thing to correct oversteer/understeer. It might actually save you from putting it into a gutter.

The only reason to lockbar it down is that HICAS is interfering or if HICAS is flat out malfunctioning, and usually it requires driving at the track to notice it.

you should pull off the steering wheel and check how the boss kit is interacting with the HICAS hub behind wheel/boss kit.

if the light is coming on straight away everytime you start the car then it might be another issue, most of the time if its the boss kit it wont come on till a couple of minutes of driving above 80kmh, or from what I understand anyway

This is what happened to me, no HICAS light then as soon as I went over 80 for a while it would come on and stay on. My Boss kit was on wrong and wasnt Turning my HICAS HUB correctly, there was a couple of degrees of slop in it

Pull your wheel off and have a look, then try the diagnostics. If your not gonna track the car then you may as well keep it on your car

my hicas comes on straight away after i put keys in, turn on ignition and start.

i'll try taking off the steering wheel but won't have a clue what i'm looking for though.

lol..

I think there is a fuse you could pull to completely deactivate it. then just leave it. I hate

what it does to my car above 80k and would rather be without it but that will come soon lol. my airbag light is always on but that is due to the clock spring being broken behind the steering wheel. that will stay that way till i get around to fixing it.

Pulling the fuse on R33/34 will definitely cause issues - no idea on R32, however (as it's hydraulic), but I would imagine so.

      Pillar gauges

      By MBS206 路 Posted

      See, that button sounds like perfection Duncan! My eyes really don't like light shining at them from a dash when I'm driving. Being part red colourblind, I've found for most cars that I can change colours on, I set everything to red, so my eyes see the elast amount of colour! I miss normal gauges in cars

      bro, knowing the Japanese in  the 90's, i wouldn't be surprised if they shared components across their model lineup.

      Possible swap on R34 RB20DE NEO?

      By Kapr 路 Posted

      Maaaan so many "little" things  i rly hope my old RB20 would be "ok" and not too bad. I try to learn what and what not do i need. I look at crossmember at it looks different...even parts numbers are different. Wiring and all that i rly do not know...yeah someone mentioned the speedo thing. On that yoke clip. I rly do not know what can and cant be done "custom" so that is why iam asking to know and not be suprised 馃檪  I know what it looks like

      By GTSBoy 路 Posted

      Oh, there's also the gearbox crossmember which will probably be different between the small box and the big box, and the wiring loom will probably need to be modified, because the plugs for the switches etc, will probably be different. And I think the speedo on the small box R34s is from somwhere stupid, like the diff, possibly, so you'd need to work out what needs to be done about that (assuming it is different). I think the thing you need to realise is that the front end of that yoke is a large hollow tube with splines on the inside that mates with the splines on the box's output shaft. It is a dedicated thing - not available "aftermarket". They were made to suit that box, by the car's OEM.
