Gday to all you R32 guys...

I have an R32 GTST and after say 10mins of highway driving at say 70km/h+ my car feels as if it loses its rear grip for a half and instant - scary stuff. My HICAS light then comes on.

I have deduced with the help of my new mechanic that it is the HICAS system changing the steering direction of the rear wheels. When you first start up the car apparently the rear wheels steer in the opposite direction to the front but after several minutes of driving they revert to the same direction as the fronts / / to / /

/ /

if you know what i mean...

My question is... does your R32 suffer this herendous and sh#t scary tail wag as it changes??? When i say scary i mean drift style sideways (so it seems)...

Your feedback is much appreciated...

Mine's fine, never had any probs with it in the last 14 months. My hicas light used to come on but it was caused by a leak in the power steering pump. The light is only a warning to tell u if its not working. The hicas only moves the rear wheels something like 1.5deg either way depending on speed. Hope this helps :D

Mine does the same thing. I have almost taken out cars when you get caught in rydges in the road. Bloody scary.

My hicas light is on and my steering has gone heavy. I think it might be the power steering solenoid down near the rack.

Let me know if you sought it out.

Cheers guys...

yeah Doc, that's it - it goes really heavy and sometimes my car actually stalls if it occurs at slow speed.

I remember now that my mechanic said it had something to do with the aftermarket steering wheel i have because the sensor is apparently linked at the steering wheel and when they fit an aftermarket jobby it screws up the system somehow.....

Haven't had any problems with my HICAS on the hwy. Did save me from a great mess once though when I saw a turnoff too late and hooked it hard left at (undisclosed)km/h.... Instead of sliding off the road and into that big tree...I was carried merrily on my way & into the corner - felt bloddy wierd!

When I first start the car, I have to turn a left & right a little before the steering becomes light again.

Also If I idle the car for too long the HICAS light comes on. I've tried running the diagnostic, but it wouldn't work :confused:

MY R32 gtst won't show the hicas light at all. Full stop. There is no light from what I've seen. It seems to turn o.k, but i've NFI if the 4ws is actually working or not. The computer is still plugged in under the rear parcel shelf, the rack is still there, all of the hydraulic lines are still there... I dunno?

mine isnt really disabled properly it just doesnt work lol

im waiting for Dr-Drift to come over with my pineapples so i can pull the plug on the hicas and disable it properlly... but if u ask me... its a hell of a lot better... i hate how it pulls to certain sides when driving before it stops working... even before i stuffed it i hated the feeling it gave when turning.

Had the same problem and took it to givin wood on the gold coast.

The problem was the steering selector for the hicas.

It seems that there are two types and on one the selector is at 38 degrees so that at speed the thinks it is in a permanent left turn. this problem is only fixed with the correct part or by a hicas lock kit.

I've never had any issues..

Just a question for all those who are saying that they have a hard to turn steering... have you checked the power steering fluid recently?

Have you changed it at all?

As for the drift pineapples... they do not do anything for the HICAS. I believe that they are simply for stopping axle tramp, and allowing you to set your car to drift a bit more stable.

The only way to disable HICAS on our R32's is to get a proper lock kit.

You can't just disconnect the computer cause that means that the rear is then able to turn 1.5 degrees in any direction the road drags it.. NOW THAT would be scary.

When your HICAS is working properly, it only works when you are traveling above 80kms. And it ONLY works to turn the rear wheels in the SAME direction as the front to make lane changing on the highways, a smoother process.

So this thing about your mechanic telling you that it turns opposite at low speeds and same at high speeds is false.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
