Put in laymans terms HICAS makes the car easier to drive on the limit but not faster. So if you think you are good enough, lock it and you might gain a bit of lap time. It doesn't start working till you are aggressive with the car, so it won't help you park the car or get around the supermarket easier.

OK i have a R33 with Hicas.I cahnges the steering to an after market wheel now the hicas light comes on. I thought it may of been the boss kit but where i bought it from assures me it correct.My fluids are topped up but the hicas light still comes on after about 20 minutes of driving and normally once i reach over 80km-100km per hour approx. If you have a soulution to my promlem it would be great if you can email me at

thanks

My Hicas light comes on now and then. Standard steering wheel. When my car is goingstraight ahead the wheel is rotated a few degrees...is this a possible reason. Or is it more serious. IId just like to get the annoying orange light off the dash. If I pull the fuse when the light is off will this keep the light off or will it just stay on??

Thanks

From what I know pulling the fuse will cause the light to come on aswell.

My wheel is also not centered when the car is going straight. I assume its just a dodgey install of an aftermarket wheel though (I didnt do it!).

The light coming on shows that there is a problem with the sensors. HICAS kicks in after 80kph. so if the light is coming on that means that the sensors either in the steering wheel or the sensors on the wheels dont line up. My advice is to get the steering wheel re done and get someone to check the angle and camber of your rear wheels. If the light is constantly on then there is a real problem, usually the car has had a aftermarket steering wheel on and had it removed before selling. So if you can, remove the steering wheel and check the sensors, or take it to someone that can do it.

Check your fluid levels too.

the hicas light on my car pretty much stays on all the time but occasionally turns off, i have an r32 i was wondering if the diagnostic procedure is the same .

They are different , R32 = Mechanical - R33 = Electronic - id say it saves weight being electronic. Not sure about later R32 GTR models like the 94, maybe have electronic.

No, hicas light does not come on when becomes active.. I noticed some people dont realize their hicas is working, obivously havnt driven enough in other cars. to know the difference.

Vehicle: R32 GTR

Problem: After a minute or two the steering becomes heavy, soon followed by the HICAS light illuminating on the dash cluster.

My Solution: HICAS ECU is kaput! This can be located in the boot on the drivers side under the parcel shelf.

How to test yours: Under the parcel shelf three 10mm head bolts hold in the ECU, undo these then unclip the ECU, replace with one from a car with working HICAS. For my test I used the HICAS ECU from a R32 GTSt, worked excellently, only took 5 mins to d the swap and back, and probably about 10 minutes driving it. Hopefully this will make it easier to test the ECU before you buy and fit a lock bar and rip out all the HICAS system.

My problem, which I've had no luck in getting anyone to know what I'm on about:

Sometimes when I turn on my car (not all the time, it didn't do it for around 3 weeks but now it's about every third time I turn it on), the HICAS light stays on. Solid. The whole time it's on, it feels like I have no power steering, eg. the wheel is sluggish and hard to turn.

I've checked fluids. That's all fine there.

I've got a MOMO steering wheel, but the HKB boss kit (HKB = HICAS compliant), so there's no problems there. If there was a problem there, it'd be permanent, not just every now and then.

Anyone got any ideas? I'll be performing a diagnostic this weekend, so I guess I'll post up the results of that then rip the car apart till I can find it. Then lock the damn thing down anyway.

consult that bad boy, or try swap ecu with a friends?

i have a small question.... if i start my car (R32) abd just let it idle for about 5 min the light will light up and stay on!!!!! what is this?

And the steering goes real stiff!!!

But when i turn it off and on again, as long as i move or start driving it will be sweet!

just wondering is that a normal thing?

cheers

Hi Kezza,

Seems that you and CPD are experiencing similar problems, just different signs. My guess is that both computers in each case are dying or are close to it.

Check with some wreckers for a HICAS unit (SSS /Just Jap/ ebay perhaps)

Simple plug and play computer located in the boot on the upper inside of the boot line near the battery.

Try that guys see how you go.

Better yet, get a mate's car and play swapsies and see what happens.....

Cheers

Loz

Thanks lozza, im not sure if i should just leave it till it does die... or get in now and do it b4 it does!!! it only seems to do it sometimes, and its only when your not using the steering... just idling for over 5 min!!! hard to say hey!!! maybe the subs are killing the computer, seeing its so damm close to the subs!!! but thanks for your help :D

What I'm going to do is rip out the HICAS computer (I'm assuming it's the shiny silver box attached to the underside of the parcel shelf?) and check to see if there's any loose connections in it or the cable going to it. Because it's only every now and then, it might be due to a loose connection, so here's hoping.

Lozza, my problem isn't so much when it sits there idle, it's just randomly (around 30% of the time) when I turn the car on, HICAS light will be on and steering sluggish, and it'll stay that way until I turn it off and wander off, say to the shops. Even then, sometimes it'll be on again when I come back, but all in all, say 30% of the time. But yeah, checking the computer time, methinks.

maybe this is two problems, but linked to the speed sensor in the dash?

my hicas was fine when the dash fuse blew, worked fine and powersteering didnt go heavy, now it has the dash running again the same old problem is occuring

I have the same problem as you, would be good to know if we can find out what it is

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
