latly my 32's hicas light has been comen on after a little while of driven.

after driven it around for quite a bit since the light has been coming on i have now narrowrf it down to these factors

if i drive for a long period of time it comes on

if i drive for 5 mins slowly and then i boost the light comes on

the light comes on and does not disapear untilli turn the engine off.

so pretty much i have came to the conclusion that if i boost or do highway driving where the wheels are spinning quite quickly my hicas comes on.

i have taken it to a normal mechanic and they had no idea what a hicas really was so im after specific help

what can i do/check to stop the light comen on

where is the hicas fluid located? i see the power steering but is there a seperate 1 for the hicas?

Its the same thing really.

Now I gota GTR (Might be the same as GTS-T, Im not sure, just have a look)

- OK so you check the one at the front in the engine bay. Make sure thats topped up.

- NOW open your boot / As you are facing the boot, on the bottom right handside, there is a panel you can unscrew, there will be another tank/resevour, Top that up with powersteering fluid.

The same thing happend to me and what is said above is what I did. End Result = My HICAS Light turned off.

I have posted this before BUT some ppl seem to think the tank/resevour in the boot is for the ATTESA-ETS...

Only other thing I can suggest its to get your mechanicn check the fuese in the fues box, do a wheel alignment and even diagnose the cars ECU to see if it can pick up any faults in the system if the light still does not turn off.

BTW let me know how you go about filling up the rear tank/resevour (thats if you have one, LOL!), if that is topped up and switches off the light then I can say its for the HICAS.

i had the same problem man, fill up your power steering fluid and then fill up the rear hicas aswell, then start the car and drive it for a while for about 5-10mins and then you will know if there is a lak in your hicas system because i had the same problem and my mechanic told me to do that, and also go get a wheel alignment and im pretty sure you would be ok, i was at the stage of removing the hicas but i ended up fixin it, hope that helps mate,

cheers

My HICAS light comes on in my 32 R after several minutes of highway driving also...

All fluids are fine. Anyone know why it does this? Does it do this with all 32 R's or? Maybe I have a HICAS lockbar? Would the light be on always if I had a lockbar or never?

The reservoir in the boot on the right IS for the 4WD system. Still requires power steering fluid, but is not for the HICAS.

Wheel alignment, steering wheel sensor...

Then check the HICAS computer at the back...

Ok just to clear some things up.

Yes the R32 GTR does have a hicas fluid reservoir in the back right of the boot. NOTE any other varient R32 including GTS-t GTS will not have a reservoir there so don't bother looking.

Wheels alignments should only be a last resort IMO. Here's some possiblilites.

1: If you have an aftermarket steering wheel, you SHOULD have a hicas bosskit or your light will stay on continously.

2: Your hicas ECU in the trunk, on the underside of the parcel tray may have a fault.

3: Possible leaks in the steering / low power steering fluid.

4; If your hicas has been deleted you should be able to see a lock bar in there (in this case you don't need to worry about the light)

If all else fails just eliminate hicas altogether. It's cheap and you'll find handling alot more predictive.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
