The issue on HICAS

[cynicks]

I've heard alot of issues on the GTT R34 HICAS. I've experience it once of the 5 months ownership of the car. How can we make sure that the light doesn't pop up again ?

My experience was a leisure drive from Dsara to Puchong, and then back to Dsara. On the way back, it pops up, but nothing 'physical' happen to the car, it still drives, turns ok. Straights ok. I reached home, died down the car, restart, It WAS GONE. :hmmmm:

Any advise are appreciated.

Also, recently my Turbo timer will count down on the 1st start in the morning, eventhough my keys are still at the ignition and turned on. Only the 2nd time, the timer would not cut off the car, but still count down. Its a black Apexi timer. :hmmmm:

Any advise also appreciated :proud:

That's not the worst issue with HICAS. A few people in the UK has discovered that HICAS can suddenly activate even during driving straight. This is very dangerous especially at speed, and some people have attributed their accidents to this malfunction.

Apparently this occurs when the car has a loud subwoofer and the vibration interferes with the g-sensor or something.

I've seen some people remove the whole thing and driftworks in UK sells a complete replacement kit.

However defenders of the system say as long as it well maintained and serviced (and there's no big subwoofer pounding in the boot) it should be fine.

HICAS? who uses hicas? hehehehe..

 

[Temujin]

I'm still using HICAS!

The HICAS light went on even before I bought the car, luckily it was due to low fluid. No prob so far. Try checking the HICAS fluid level..

I contemplated removing it, but since I'm not drifting or doing any motorsport professionally, I decided to leave it. Love the cornering ease with it.

Option to remove costs as cheap as RM350 for new HICAS cancel bar (US made) as well as yanking out the system. Should save u around 20-30kgs.

Err GTT HICAS is electrical motor type, hee.

cynicks:
HICAS faulty on GTT mostly from faulty ABS/Speed sensor. You may check it with CONSULT
1st to make sure which sensor is not working.

But getting a new sensor might expensive compare to HICAS cancel rod~

Apexi timer? Should be the wireman tapping a wrong wire?Hopefully is not a imitation ones~hee

Oooo.. Mine old car still using hydraulics.. Old car for old man..

hicas,trc ....whats that

So I guess, some hardcore guys here have it surgically removed huh... Where's the best 'hospital' to do this kinda operation? I'll check the fluids and top up and see if it happens again. Is this the power steering fluid reservoir?

Any good mechanic can do it bro, taking off stuff is easy. You can also just use a lockout bar but the light will be permanently on.

The fluid reservoir is in the boot on the side.

That's not true.

HICAS good, makes cornering easier,
remove hicas, makes car more predictable, can throw backside easier,
depends on what u want..

 

[Blood Red]

cynicks.... i think u bought the imitation TT. Same symptoms like mine.. Soon it will be kaput.

Insya Allah...

 

[gobiz2]

That's not true.

How so?

 

[[PIMPIN]]

How so?

Well I know which threads you're referring to on GTROC because I went through quite a few some time back. It's inconclusive plus it's hardly common.

 

[V-Spec]

Yea. I've read of how ppl complaining it's unpredictable, etc....

Never had issues or any drama with mine. So why throw away a tool to assist in cornering?

 

[Temujin]

HICAS does screw up ur fun if u intentionally want the tail to come out. But of course, there is only so much angle that HICAS can do (5 deg or sumthing) so it is still possible to slide the back with HICAS still functioning.

From my short experience of having a non-HICAS and a HICAS-equipped Nissan, the system is good to have but not essential. With HICAS (and ATTESA) cornering speeds are higher, while without HICAS cars with RWD will easily get their tail out.

People say HICAS will make cornering unpredictable etc, but seriously how often do people take the cars on the edge at the track? The only thing that appeals for me to remove the system is the weight saving.. 20-30kgs is a lot of dieting.. far cheaper than getting dry carbon body panels..

If u decide to remove the system, just be careful in the wet

 

[Dr.D]

quite difference with HICAS and with out hicas, cornering alot easier and feel safer, but then again how many drivers push there cars to the limit and still enjoy the control at the limits.. for average drivers, do keep the HICAS... another is make sure ur tyre OD all same to make sure the electronics n traction control is in optimum operation, mis reading from sencors can cause HICAS to mal function

HICAS max is 1 deg IIRC.

Anyways, you've pretty much summed up my POV in your post. Unless it's a proper track/race car I don't see the point in removing the HICAS. I guess if I do venture down the psycho hardcore path then I'd feel differently.

 

[shark79]

well there must be a solid reason it is oem right

 

[Dr.D]

the reason of oem is becouse skylines are nose heavy. so u dont really want the car to be tail happy. once u counter weight each corner of the car, the car feels more balance.. thats why the HICAS is removed on most of track cars in event of GT500, jpn GT, even group A and N is removed, le mans etc
