heyas, this problem has been around for about a month now, sometimes its there for days but then the power steering comes back on occasions. Ive checked the power steering/auto fluid and its fine, the fuses have been changed recently and the problem stopped for about a day but now its back. I saw a thread on this problem awhile ago but no one seemed to have solutions, mostly theorys. Anyone have any ideas what it could be, or where the best place to go get it checked out or fixed? thanks a lot

Gauth.

Sneeza, 180SX's and Silvia's have it too you know :rolleyes:

However it was an option which means theres also a helluva lot of 180's and Silvias out there without Hicas.

Steve as usual has generalised to the point of being incorrect. It shouldnt be removed from ALL cars asap, because for starters not all cars have it. There is nothing inherently wrong with 4WS systems its just some people dont like the feel of it, each to their own. Ive never driven my car without it so ive got no idea what its "meant" to feel like.

Unless you are having problems with your HICAS and youve got no issues with the cars handling, theres no reason at all to disable it. Besides HICAS lock kits are yellow sticker material.

R32's in particular seem to be having all the HICAS issues of late, but it might be something to do with age. Perhaps the 33's turn will be soon :)

Hope i'm not hi-jacking here, but i think my HICAS is playing up.

It seems whenever i'm turning a corner and hit a bump, the backend kind of floats to a side. Its hard to explain, but it doesn't feel good at all! Almost loosing control type of feel.

I'm going to disconnect it this weekend,and if anyones interested, will let you know the results.

Having experienced my GTR both with and without HICAS I definately prefer without.

The HICAS takes inputs from vehicle speed and steering wheel position to determine in what direction the rear wheels move and by how much.

Unlike the ATTESSA 4WD system, it doesn't take inputs from individual wheel speed nor from axial or lateral G forces.

When the car is being driven sedately or even moderately hard it does make cornering easier.

When on the limit such as track work, the HICAS system will not pick up that the rear end is sliding and will actually turn into the corner more.

I have found by locking out the HICAS that the car is more predictable when the rear has broken traction.

Each to their own I guess depending on what you plan to do with your car, however I have no plans to refit mine.

Ok, so the HICAS is causing major probs in my car.

Should unplugging the major plug that goes down to the HICAS stop it from working?

Thats what i've done, and found the orange light on the dash lights up. But i still have the problem when i go over bumps, it throws the car out a bit.

So this means that it is either still working, or something mechanical has stuffed up inside the hicas.

As i am only a recent R33 owner I no not too much about them.

From what i understand the HICAS indicator only lights up when there is a problem with the HICAS. Ie when the engine is not on.

Therefore it would also light up if you unplugged the 'major plug'.

Also the HICAS as i understand only alter +/- 1 Degree or part of.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
